ALT series asphalt drum mixing plants are Aimix self-developed products. Due to its low energy consumption, easy installation and other characteristics, asphalt drum plant is widely used in the highway and municipal constructions for more than a decade, obtaining high praise from customers. In recent years, Aimix asphalt drum mixing plants have been penetrating into people’s life with more excellent performance and more stable mixing quality after continuous improvements. It plays a more important role in city and rural road constructions day by day.
Main Features Of Aimix Asphalt Drum Mixing Plant :
Asphalt drum mixing plant is mainly consisted of aggregate batching system, drying & mixing systems, bitumen supply system, dust collecting system, finished material elevator, finished material silos, electrical control system. The whole body adopts modular structure, for example, the aggregate batcher, aggregate collecting belt and conveying belt of aggregate batching system constitute a convoying unit; the drying & mixing system is a single unit. In this way, the transportation and installation of asphalt drum mixing plant become very simple to operate. That’s why Aimix asphalt drum mixing plant is so popular with worldwide clients.
Aggregate batching system main includes: batch hopper, feeding belt, collecting belt, vibrating screen and belt conveyor. There are 4 batch hoppers carrying aggregates with different specifications to meet the gradation requirements of asphalt mixture. At the lower part of each batch hopper equipped with adjustable belt feeder, which can realize stepless speed regulation. The collecting belt under the hoppers will collect the aggregates and transfer them to the vibrating screen. Particles with diameter greater than 40mm will be screened out, and the rest will be sent to the belt conveyor. Then the belt conveyor will move the aggregates to the drum dryer.
Drying & mixing system consists of drying cylinders, combustion devices, and oil ignition system components, etc. Drying drum contains 4 carrier rollers, 2 rolling rings, 2 blocking wheels, a cylinder and shovel plates. The cylinder was supported by carrier rollers with its rolling rings and driven by the reduction gears stably and evenly. When aggregates get into the drying drum, they will be raised by the shovel plate to the highest point and then poured down, forming a wall where the fire will go through to dehydrate the materials. The cylinder is rolling with inclination of 3.5°to get the aggregates mixed with bitumen and out off the cylinder for elevating in right time.
The bitumen supply system is composed of bitumen tank, bitumen gear pump, pipes and bitumen spray tube. The gear pump is driven by the adjustable-speed motor and transfer the bitumen from bitumen tank to the drying drum for mixing process.
The dust collecting system has two collecting levels, cyclone dust filter and water dust collector. The purified air flies up and gets discharged from the chimney, while the dust mud sinks in the sedimentation basin thanks to the gravity.
Finished product elevator has driving device, chains, chain wheels and a hopper. Its main function is to raise the finished product up to the storage silo.
Finished product silo is used to temporarily store the asphalt mixture before truck loading. It mainly includes stand columns, storehouse, ladders, etc.
The Electrical control system which adopts centralized control technology, is composed by distribution cabinets, control room and other small auxiliaries. All the electrical components attached to the distribution cabinets are brand products, qualified and durable.
