The wet batch concrete plant is the commonly used concrete production equipment. According to the different needs of users, it may have different configuration. However, the main systems are same, which include concrete mixer, material weighing system, material conveying system, material storage system and control system.
1. Concrete mixer
The concrete mixer a wet batching plant adopts is JS concrete mixer, that is twin shaft concrete mixer. It is the mainstream concrete mixer machine for concrete batching plant. It can can mix a variety of concrete such as fluidity, semi-dry and hard, which has he advantages of high production efficiency, energy saving and environmental protection.
2. Material weighing system: PLD batch machine
Material weighing system is a key component that affects the quality of concrete and the production cost of concrete. It is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing. The production of concrete with different specifications mainly depends on the weighing system.
3. Material conveying system: screw conveyor
Material transportation consists of three parts:
Aggregate transportation: At present, there are two methods of hopper transportation and belt transportation in the concrete mixing plant. The hopper lifting are of small footprint and simple structure. The belt conveyor is of large conveying distance, high efficiency and low failure rate.
Powder conveying: The powders available for concrete are mainly cement, fly ash and mineral powder. At present, the commonly used powder conveying method is screw conveyor, which is of simple structure, low cost and reliable use.
Liquid delivery: It mainly refers to water and liquid additives, which are delivered by water pumps.
4. Material storage system: cement silo
The storage methods of different wet mix concrete plants are same. Aggregates are stacked in the open air, powder materials are stored in fully enclosed steel structure cement silos and admixtures are stored in the steel structure containers.
5. Control system
According to the scale of concrete batching plant and the requirements of different customers, the control system can have different functions. It can fully automatic or semi automatic. the control system of the small concrete mixing plant can be a little simple while that of the large concrete batching plant is relatively complicated.
