Concrete batching plant is usually divided into three types:
1. Stationary Concrete Batching Plant which is characterized by large output, high efficiency and small cover site.
2. Assemble Concrete batching plant which adopts the double type mixer, which is characterized by convenient removal.
3. Mobile concrete batching plants. The mixing machine, feeding machine, platform and silo are all self-contained, and they can be towed easily.
The single stage concrete batching plant usually uses the belt conveyor to lift the aggregate to the top floor of the mixing station and unload them into each bin respectively;
The double stage concrete batching plant usually adopts Forklift trucks and loaders to upload the aggregate. The water, the admixture and the admixture are respectively provided with a container storage and a pipeline pumping facility.
The measurement of coarse aggregate, mobile concrete batching plants usually adopts the Loadometer weighing;
The stationary concrete batching plant usually adopts the lever type weighing hopper or electronic scale. Water and liquid additives are mostly measured by flow meters.
There are two kinds of concrete mixer: one is the self loading concrete mixer, the other is twin shaft compulsory concrete mixer.
(1) Self loading concrete mixer. There are some radial stirring blades in the inner wall of mixing drum, repeated lifting and self loading the material, to achieve uniform mixing, This self loading concrete mixer is characterized by simple structure, high durability, convenient maintenance, mainly mixing the plastic concrete in general, whose discharging mode is reversed discharging and tilting material.
(2) Twin shaft concrete mixer. The rotating shaft of the mixing drum is equipped with stirring blades, and the material is stirred and stirred into the cylinder to form a cross flow, and mix the concrete well. This method of mixing is stronger than the self loading mixing.
In the automatic control concrete mixing station, the electric, hydraulic and pneumatic systems are centrally located in the control room for centralized monitoring.
