With the high development of human society, and in order to provide human beings with a high-quality and guaranteed life, it is necessary to build various living facilities that are shock-proof, noise-proof, dust-proof, storm-proof, environmentally friendly, and keep warm. Then the concrete mixing plant It is one of the essential key equipment.
What’s the Concrete batching plant?
In short, the concrete batching plant is mainly composed of material storage system, material weighing system, material conveying system, mixing system, powder storage system, powder conveying system, powder metering system, water and admixture metering system and control system and five major systems and other auxiliary facilities.
Mixing host
According to its mixing method. The mixing host has forced mixing and self-falling mixing ,Forced mixer is the mainstream used in mixing plants at home and abroad. It can mix fluid, semi-dry and dry-hard concrete. The self-falling mixer mainly mixes fluid concrete, which rarely appears in life
Compulsory mixers mainly include main shaft planetary mixers, single-horizontal shaft mixers and twin-horizontal shaft mixers according to their structural forms. Among them, the comprehensive performance of the twin-shaft forced mixer is the best.
Weighing system:
The material weighing system is a key component that affects the quality of concrete and the cost of concrete production. and it has three parts: aggregate weighing, powder weighing and liquid weighing.
The weighing accuracy of aggregate is ±2%, and the weighing accuracy of cement, powder, water and admixtures all reach ±1%.
Conveyor system:
Material conveying consists of three parts:
Aggregate conveying: The mixing plant conveys in two ways: hopper conveying and belt conveying. The advantages of hopper lifting are small footprint and simple structure. The advantages of belt conveying are large conveying distance, high efficiency and low failure rate. Belt conveying is mainly suitable for batching plants with temporary aggregate storage silo, so as to improve the productivity of the batching plant.
Powder conveying: The powders available for concrete are mainly cement, fly ash and mineral powder. The commonly used powder conveying method is screw conveyor conveying, and large-scale mixing buildings use pneumatic conveying and scraper conveying. The advantages of screw conveying are simple structure, low cost and reliable use.
Liquid transport: mainly refers to water and liquid admixtures,There will have the water pump to transfer
Storage system:
The material storage methods available for concrete are basically the same. Aggregates are stacked in the open air (there are also closed silos used in large urban commercial concrete mixing plants);
powders are stored in fully enclosed steel structure silos;
admixtures are stored in steel structure containers.
Control System:
The control system of the mixing station is the central nervous system of the whole equipment. The control system has different functions and configurations according to the different requirements of users and the size of the mixing station. Generally, the control system of the small mixing station available on the construction site is simpler, while the system of the large mixing station is relatively complex.
