concrete mixing plant

The concrete mixing plant is mainly a large-scale facility consisting of a weighing system for the main materials of the mixing device, a material processing system, a material storage system, and a control system as auxiliary systems.

1. Material handling system

Material conveying consists of three parts. Aggregate transportation; At present, there are two ways of conveying in the mixing plant: hopper and conveyor belt. Advantages: The bucket elevator has a small footprint and a simple structure. The advantage isThe conveying distance of the belt conveyor has a low failure rate. Conveyor belts are mainly used for aggregation mixing plants and temporary storage of mixing plants to improve productivity. Transfer powder; The available powders for concrete are mainly cement, fly ash, and slag. At present, the commonly used screw conveyor for powder conveying includes a large mixed plant pneumatic conveying and AFC. The advantages of Og are simple structure, low cost, and reliable use. Liquid transportation mainly refers to water and liquid additives, which are delivered separately by water pumps.

2. Material storage system

Concrete can basically be used to store the same materials. Outdoor stacking of aggregates (products in a large city, blocking concrete mixing plants); Powder storage silo fully enclosed steel; A storage container mixed with steel.

3. Control system,

The entire device is controlled by the nervous systemmixing plantAccording to the different requirements of users and the size of the mixing plant, the control system has different functions and formulations. Small mixing plants can be located in the construction control system, which is generally simple, while large mixing plant systems are relatively complex.

4. Host mixing

Enter the mixing and free fall mixer according to their method, and use a forced mixer mixer. The forced mixer is used in mainstream mixing plants abroad, and it can mix flowable, semi-rigid, rigid, and other dry concrete. The self mixing console is mainly used for mixing flowable concrete and is rarely used in mixing plants.
