Introduction of batch mix bitumen batching plant
We can divide the bitumen batching plant into batch mix bitumen batching plant and drum mix bitumen batching plant. Batch mix bitumen batching plant: These plants produce asphalt mixture in batches.
The difference here is not just the way of production. And there are different quality hot mix asphalt produced by each equipment. This batch mix bitumen batching plant can also be modified and used to produce hot mix asphalt using recycled materials.
All asphalt batching plants are have same operations
● Cold aggregate storage and feeding
● Drying and heating of bitumen.
● Screening and storage of hot aggregate
● Storage and heating of bitumen
● Measuring and mixing asphalt, aggregates and fillers
● Loading finished asphalt mixture
● Control all operations of the plant through the control panel.
Detailed features of batch mix bitumen batching plant
1. Aggregate supply system
(1) In order to make the supply smoother, vibrators are installed under each hopper.
(2) Add a grid plate at the top of each hopper to cushion the impact of the aggregate flow, and at the same time sieve the oversized aggregate;
(3) The conveyor belt is protected by a dust cover to reduce dust emissions.
(4) Add belt cleaners and pressure rollers to make the supply of aggregates smoother and more accurate. In addition, they extend the durability of the belt;
(5) A small vibrating screen was added between the belts to further screen the oversized aggregate;
2. Drying system of bitumen batching plant
1) The drive unit is equipped with an automatic lubrication device, which greatly reduces labor costs;
2) Different areas within the drying barrel have different blade which can handle aggregates in different processes.
3) Rolling rings and rollers are using high-strength wear-resistant materials. Anti-deflection rollers with two rolling rings
4) The cylinder adopts boiler steel and stainless steel skin, which has high temperature resistance and no deformation;
5) The steel cylinder adopts thermal insulation rock wool material, which can maintain the internal temperature and reduce heat loss.
3. Mixing system of bitumen batching plant
(1) The best materials with high hardness and high wear resistance are used for the mixer, the mixing blade and the liner.
(2) The cycloidal pin gear reducer has better transmission efficiency and simpler structure.
4. Dust Collecting System of bitumen batching plant
1) Multi-staged dust catcher, could reclaim different sized aggregates, increasing utility of aggregates and making sure the quality of hot mixture
2) Snail shell filter could adjust aggregate size, to meet different demands
3) Drawing fan dumper auto adjustable, ensure constant negative pressure in drying drum
5. Screening system of bitumen batching plant
(1) High strength manganese steel screener mesh with enhanced rim, long lifespan
(2) Subsection and layer equipped screener, easy for replacement and maintenance
(3) Vibrator well sealed with wind induced pressure relief, non dust spillover;
