At present, Kenya is making every effort to promote the national road expansion and upgrading project, so as to stimulate the cross-border regional trade circulation in East Africa, open up the remote rural traffic network, open up the export channel of agricultural products, and comprehensively drive the national economic growth and employment increase.The Kenyan government has continuously implemented a number of national key infrastructure plans, covering the whole country: widening and renovation of national trunk roads, new construction and repair of county-level rural branch roads, blackening of roads in urban blocks, emergency repair of flood and vehicle damaged roads, etc.The construction terrain of the project has a large span, with construction sites in coastal flat plains, central plateau hills and western blocked mountainous areas. The site conditions and power supply logistics facilities vary greatly from place to place.
There are four prominent pain points in local road construction: firstly, the project points are highly dispersed, and the same construction enterprise often undertakes multiple bid sections separated by hundreds of kilometers at the same time; secondly, the construction cycle of a single project is short, and it needs to be transferred to the next area immediately after phased completion; thirdly, the water and electricity, storage and transportation facilities of remote rural construction sites are seriously insufficient; Fourth, long-distance transportation of hot-mix asphalt mixture is prone to cooling and aggregate segregation, which not only greatly increases the cost of fuel and transportation vehicles, but also directly causes quality defects in pavement paving, and a large amount of capital is lost in later rework.The traditional fixed asphalt mixing plant has fixed site selection, long civil construction cycle and extremely high transfer cost, which cannot adapt to Kenya's mobile and multi-point construction mode. The market urgently needs asphalt mixing equipment with fast deployment, strong mobility and local conditions in Africa. Therefore, the ultra-mobile asphalt mixing plant has become the core equipment just needed by local engineering contractors.

What is an Ultra Mobile Asphalt Mixer?

The ultra-mobile asphalt mixing plant is a complete integrated asphalt hot mix production system equipped with a heavy-duty trailer chassis and fully modular integration.Six core functional units, namely, cold material feeding and screening, aggregate drying and heating, precise metering and batching, forced mixing, tail gas dust treatment and asphalt insulation supply, are independently integrated and installed on special mobile trailers. It is a complete set of mixing equipment developed by Sinode for African decentralized road projects.
Ordinary semi-mobile mixing plants on the market still need local concrete bases, and the disassembly process is cumbersome; while ultra-mobile asphalt mixing plants completely get rid of the restrictions of heavy civil engineering foundation.Equipment transfer only needs to disconnect the circuit, oil and gas transmission pipeline, single or multiple trailers can be towed by the tractor for long-distance transfer.After arriving at the new construction site, it is not necessary to harden the foundation with cement, and only the sand and gravel ground can be leveled and compacted to complete the placement and positioning; the hydropower pipeline can be quickly connected, the whole machine debugging and calibration can be completed, and the material can be put into production in a short time.The asphalt mixture gradation, temperature and uniformity produced by the whole set of equipment are completely consistent with those of large-scale fixed mixing plants, and at the same time, it has the advantages of rapid transition that fixed equipment does not have. One set of equipment can serve dozens of scattered road sections in a circular manner.

Why is the ultra-mobile asphalt mixing plant suitable for Kenya construction scenarios

The unique geographical distribution, construction period requirements and site conditions of Kenya road project make the ultra-mobile asphalt mixing plant an irreplaceable optimal supporting scheme, with three core values meeting local needs:

Adapt to the layout of large-scale scattered construction throughout the whole territory

Kenya has a wide territory span, scattered distribution of highway main line, rural branch line and mountain repair section, and construction enterprises often need to allocate asphalt mixing capacity across counties.The ultra-mobile mixing station can follow the paving team to the front line of operation, and the mixture can be produced and used locally. The transportation distance shall be controlled within a few kilometers, so as to avoid the mixture cooling and fine aggregate stratification caused by long-distance transportation from the root, eliminate the quality hidden dangers such as pavement cracking, potholes and insufficient compaction, and save high long-distance logistics expenses at one time.

Perfect match for local tight, urgent project deadlines

Kenyan government road projects generally have strict construction periods. Subgrade and asphalt pavement must be completed before the rainy season. Old road repair is required to resume operation within 72 hours.Fixed mixing plant foundation pouring, maintenance, equipment assembly often takes months; ultra-mobile equipment omits all civil engineering procedures, site preparation, equipment commissioning cycle is greatly shortened, emergency repair tasks can be quickly mobilized for production, to ensure timely delivery of the project, to avoid overdue contract fines.

Adapt to simple and changeable temporary field construction site

A large number of rural and mountainous construction sites have no stable industrial power supply, lack of large-scale equipment parking hardening sites and supporting workshops.The ultra-mobile mixing plant is integrated and equipped with auxiliary systems. It occupies a small and flexible area. Even if the hillside is flat and small, the temporary storage yard on the roadside in the countryside can be arranged and operated normally. The equipment has a complete set of insulation, dust removal and electric control systems. It is still stable and continuous production in the wild environment of East Africa with unstable power supply, large wind and sand, and large temperature difference between day and night.

Core performance characteristics of ultra-mobile asphalt mixing plant

Trailer integrated modular design

All production modules are independently equipped with special heavy-duty trailer chassis. The frame has been strengthened with anti-torsion treatment to adapt to long-distance traction and transportation on bumpy rural roads in Africa.The whole set of equipment is divided into multiple groups of independent trailer units, with length, width and height, axle load strictly conforming to Kenya's local road transportation control standards, no need to split core large parts for cross-county transfer, no need to apply for over-limit transportation approval, and no obstacle to road traffic and long-distance transportation.Each functional unit is designed with independent trailer, which can be split and transferred separately according to the project scale. Small-scale rural projects can be used only by allocating some units, so the flexibility is greatly improved.

Fast start-up without foundation

Completely abandon the traditional mixing plant large-area reinforced concrete foundation construction, only need bulldozer simple leveling, roller compaction sand or soil hard ground, meet the horizontal placement requirements.After the equipment arrives, the trailer leg leveling, cold bin alignment, asphalt pipeline and dust removal pipeline docking, circuit wiring and metering system calibration shall be completed in turn. The whole process shall be completed within several days, and stable discharge shall be realized within one week at the earliest.Save large civil engineering expenses such as foundation reinforcement, cement and manual maintenance, greatly reduce the preparation time of the site in the early stage of the project, and start asphalt paving operation in advance.

High-precision batching metering system

Aggregate, mineral powder, hot asphalt three sets of raw materials are all equipped with imported high-precision pressure sensor weighing device, using independent dynamic measurement mode, real-time monitoring of each raw material weight, automatic compensation drop error.After the system sets the standard proportion, the proportion of coarse aggregate, asphalt and mineral powder in each batch of mixture is stable and uniform, and there will be no imbalance between coarse and fine and oil-stone ratio.The stable mixture formula can ensure that the pavement strength, waterproof property and wear resistance of all levels of roads in the country are balanced and up to standard, and reduce the frequency of road maintenance in the later period.

Efficient drying heating system

In view of Kenya's high temperature and high diesel purchase cost throughout the year, the equipment optimizes the lengthened drying drum structure, built-in multi-stage lifting blades, aggregates are fully contacted with high temperature hot air, and the heat exchange efficiency is greatly improved.Energy-saving fuel burner is equipped, fuel is fully burned, and ineffective heat loss is extremely low; even under outdoor conditions with high temperature above 40℃ at noon, aggregate is still heated to standard mixing temperature stably, significantly reducing fuel consumption per ton of mixture, continuously reducing fuel cost during long-term operation, and improving overall project profit of contractor.

Bag-type environmental protection dust removal system

Set up a large capacity pulse bag dust collector, covering all dust producing points of drying drum, stirring pot and cold bin. The three-stage dust interception filter design can collect fine ore powder and aggregate dust more than 99%. The dust emission of the construction site meets the road construction dust control standard of Kenya Environmental Management Bureau, and will not be suspended due to environmental protection failure; the collected mineral powder can be recycled and put into mixture reproduction, which not only reduces air pollution, but also saves the purchase cost of mineral powder raw materials, giving consideration to environmental protection and economic benefits.

PLC intelligent automatic control system

The whole machine is equipped with independent sealed centralized operation control room, indoor heat insulation and sun protection, suitable for high temperature exposure environment in Africa. It is equipped with mature PLC intelligent automatic operation system, supporting 24-hour automatic continuous production; the operator can adjust the aggregate supply amount, combustion temperature, asphalt dosage ratio and other operating parameters in real time on the operation console; the system has automatic fault identification and sound alarm function, and prompts the operator at the first time when there is material blockage, lack of oil and abnormal weighing; Simultaneously and completely store daily production data of output, proportion and energy consumption, which is convenient for enterprises to calculate project cost and connect supervision and acceptance data, and greatly reduce problems such as proportion error and temperature out of control caused by manual operation.

Compact layout, smaller footprint

The whole machine adopts three-dimensional compact arrangement design of upper and lower layers, eliminating redundant structure, occupying more than 30% less area than conventional semi-mobile equipment under the same production capacity. There is no need to plan a large yard, only a small narrow flat site can complete the complete set of equipment placement, perfect for county and county rural roads, narrow mountain road temporary construction sites on both sides, outstanding advantages in the field projects with scarce site resources.

In short, the core advantages of fixed mixing plants are concentrated in uninterrupted mass production in a single plant; while ultra-mobile asphalt mixing plants accurately match all construction needs of Kenya's decentralized road network upgrading project by virtue of flexible transition, elimination of high civil engineering, significant reduction of hot material transportation costs and rapid mobilization and commissioning.

Customer practical application case

A local medium-sized road construction enterprise in western Kenya has successively won the bid for several phased county road renovation projects around Kisumu, with each bid section separated by dozens to hundreds of kilometers. Before purchasing Sinode equipment, the enterprise leased local fixed asphalt mixing plant for construction for a long time, and there were three major business problems for a long time: firstly, the long-distance transportation of hot-mixed asphalt resulted in huge fuel oil and vehicle rental expenses, and the project profit was greatly compressed by logistics; second, the mixture temperature dropped due to long-distance transportation, the aggregate was layered, and the pavement flatness and compaction after paving were not up to standard, resulting in frequent rework; Third, after completing a bid section, dismantle the fixed mixing equipment and re-pour the foundation assembly. The shutdown period is as long as three weeks, seriously delaying the overall construction progress and facing Party A's construction period punishment for many times.
In order to solve the above pain points, the enterprise purchased a Sinod 60 tons/hour ultra-mobile asphalt mixing plant. After the equipment is transported to any new construction site by road trailer, site leveling, pipeline docking, metering system calibration, complete machine trial production can be completed in only 18 days, and asphalt mixing operation can be quickly put into operation. The whole set of equipment goes back and forth to serve the construction site of Jisumu and more than ten scattered counties around, and produces hot mix asphalt mixture on site, which is directly supplied to the nearby paving team. After use, the total transportation cost of finished materials of customers is directly reduced by more than 65%; the discharge temperature of mixture is stable, the aggregate is evenly mixed, the one-time acceptance rate of pavement is significantly improved, and the rework cost is almost zero. A single equipment simultaneously undertakes multiple independent bidding sections, without repeated investment in multiple sets of fixed mixing station equipment, greatly reducing fixed asset investment, and achieving a substantial increase in the annual overall project profit of the enterprise.

How to choose the suitable ultra-mobile asphalt mixing plant

Mixing plant selection directly determines the construction efficiency and long-term comprehensive income of the project. When Kenya local engineering contractors purchase selection, they need to comprehensively evaluate six core dimensions to avoid resource waste caused by blind procurement:

Match the actual capacity requirements of the project

According to the road scale undertaken by the enterprise all the year round, the hourly output demand is calculated: county and township roads, small and medium-sized old road renovation projects, 40-80 tons/hour models are the mainstream choices in the market; national high-speed widening, large-scale ring road construction and other large-scale paving projects, 80-120 tons/hour high-capacity equipment can be selected. Do not blindly purchase super-capacity models, idle capacity will increase the pressure of idle funds for equipment procurement and fuel maintenance.

Equipment size complies with Kenya local transport regulations

Check the length, width, height, size and single-axis load standard of the whole trailer before procurement, confirm that the equipment is in compliance with Kenya road traffic overrun control regulations when transferring and towing, and avoid being detained by road administration department during cross-county transfer, thus delaying the construction progress. Preference is given to models with modular, detachable trailer designs to suit local rural narrow road traffic conditions.

Fully adapted to high temperature and dusty conditions in Africa

Priority shall be given to the special African version with heat insulation protection of fuselage, fuel saving optimization of burner and stable dust removal performance of bag. The core motor and electronic control components of the equipment shall be well protected against dust and sun protection, so as to be able to cope with Kenya's field construction environment with high temperature exposure, large sand storm and large temperature difference between day and night for a long time, so as to reduce the frequency of fault shutdown.

Easy automation for local workers

It is preferred to carry mature PLC automatic control system with simple operation logic and Chinese/English bilingual visual interface, complete operation teaching manual, lower learning threshold for local workers, no need to hire foreign professional operators with high salary, and save long-term labor cost.

Supplier after-sales network and original parts guarantee ability

Focus on equipment suppliers with localized service warehouses and resident engineers in East Africa and Kenya. The construction site is mostly located in remote villages, and the parts are quickly delivered and the engineers come to repair the service, which can minimize the shutdown loss caused by equipment failure; small manufacturers without overseas service outlets are eliminated, and the procurement cycle of later parts is long, and there is no technical support for maintenance.

Comprehensive accounting of equipment life cycle cost

The model selection cannot only compare the initial purchase price of the equipment, but it is necessary to comprehensively calculate the fuel consumption per ton of mixture, the service life of wearing parts such as rollers, bags and mixing blades, and the annual maintenance labor cost, calculate the comprehensive operation cost of the full cycle of 5-8 years, and select a complete set of high cost-effective solutions with lower total cost and less failure rate for long-term use.
