We produce АБЗ (Asphalt plant) with capacity from 15 to 90 t/h.
АБЗ-60
The plant consists of the following main aggregates:
1 - Feeder aggregate. It is designed for reception and feeding (dosed) materials (sand, gravel). Composition: receiving hopper (4 pieces), support frame, weight belt feeder (4 pieces), belt conveyor receiving, belt conveyor inclined, vibrating feeder, service platforms, stairs.
2 - Aggregate of drying and heating. It is designed for drying and heating of materials (sand, gravel). Composition: furnace and drying plant, heavy oil burner, working tank of fuel oil, fuel pipe, secondary air pipe, service platform, ladder.
3 - Mixing aggregate. Designed for separation of sand and gravel into fractions (0.16 ÷.1.25mm, 1.25 ÷ 5.0mm, and more than 5.0mm), storage, dosing mixer in fractions of sand and gravel, asphalt concrete components mixing. Composition: elevator, pneumatic switch, vibrating screen, hopper of two parts, continuous operation feeders, mixer, hydraulic station, pipeline bitumen, forehearth of the finished product, supporting structure, service platforms, stairs.
4 - Aggregate of preparation and feeding bitumen. It is designed for storage, dosing, and feeding into the mixer of foamed bitumen. Composition: bitumen plant, continuous operation flow meter, bitumen pipeline.
5 - Gas purification aggregate. It is designed for removing dusty exhaust gases from drying aggregate, cleaning them from dust, separating of large (0.071 ÷ 0.16mm) and small (0.0 ÷ 0.071mm) dust, feeding purified heated air in the drying process or heating aggregates of the asphalt plant . Composition: straight-through cyclones precipitators, bag filters, exhaust fans with guide vanes, sluice gates, chimney (gas flues).
6 - Aggregate of mineral supplements. It is designed for storage, dosing, and feeding of mineral additives in the mixer. Composition: storage (silos) of mineral additives, fine dust hopper, coarse dust hopper, sluice gates, flow meters of continuous operation, screw feeders, service platforms, stairs.
7 - Aggregate of ready mix. It is designed for storage and feeding finished asphalt concrete for shipment in vehicles. Composition: skip hoist, storage bunkers, supporting structure, service platforms, stairs.
8 - Control system. Control of the asphalt plant aggregates automatically, remotely or manually. Composition: operator cabin, remote control, power cabinets, pneumatic control, sensors kit.
The plant can be equipped with aggregates for storage and feeding frezezh, fiber, chemical additives (surfactants, polymer modified asphalt cement ...), and other materials.
