Batching in the term means to categorize, but in the concrete industry, it acts like a big scale and is responsible for weighing concrete materials, including sand. Concrete batching or batching plant is an automatic system used to produce concrete on site. This system includes various devices such as mixers, silos, conveyors, etc., which operate automatically and allow workers to produce concrete with quality and uniformity. Concrete batching is used in construction projects, road construction and bridge construction.
Concrete
Batching plant or concrete device consists of the following different parts.
1. Feeder or sand tanks: The required sand is stored separately in this part, which is made from three to six houses. 2. Operator's room: This part controls all the valves and the weight and amount of materials by one operator. 3. Cement transfer spirals: This part is responsible for transferring cement from the silos to the cement scale. 4. Water meter: The volume of water needed in each batch is measured by the water meter. 5. Sand scale: This part can measure the required sand and transfer it to the mixer. 6. Mixer pot: To mix cement, sand, sand and water, these materials must enter the other part of the mixer. 7. Cement scale: Cement is stored in silos. Of course, because cement has different types, each type of cement is poured in a separate part. 8. Cement silos: This part of the concrete batching machine is used to store cement, which can be one to five silos. The concrete center station determines the number of silos required. 9. Water storage source: The water required for concrete enters the mixer after automatic measurement by the water meter.
The method of producing ready -made concrete is done in two general types:
Also, a system can be wet and dry, which is done by a two-way funnel. The most important part of a batching plant is its mixer, which is the heart of the batching plant, which is the best type because of its gearbox and high mixing power. Drum mixers are mostly used in North America, and in Europe, twin shaft mixers and pan mixers or planetary mixers are used in prefabricated facilities. In batching plants, materials are made from 2 to 6 houses, which depends on the capacity and volume of concrete needed per day. Conveyor belts or conveyor belts are usually used from 60 to 100 cm wide, which are used to transfer materials from under the main feeder. (under the feeder) and another conveyor belt (mother conveyor) which is placed from the front of the conveyor under the feeder to the mixer (wet batching) or the cement scale (dry batching).
