Introduction to production technology of concrete batching plants

 The production technology of concrete batching plants mainly includes raw material preparation, concrete mixing and concrete transportation.

Preparation of raw materials

(1) Cement and admixtures are fed into designated silos for storage according to their varieties and grades, and are fed to hoppers and metering hoppers of mixing stations by screw conveyors.

(2) The coarse and fine aggregates of the concrete mixer are loaded into sand and stone warehouses by the loader from the material yard, and transported to the hopper and metering hopper of the mixing station by the transdermal belt conveyor.

(3) Additives (liquids) are stored in storage tanks according to their varieties and pumped through pipelines to external metering tanks; mixed water is pumped through pipelines to water metering tanks.

(4) All kinds of material measurement should meet the requirements: raw materials should be measured by weight, water and liquid admixtures can be measured by volume, and the allowable deviation of raw materials measurement should not exceed the prescribed range.

concrete mixing

The concrete mixing station operators metered strictly according to the mix proportion. The first step was to pour sand and gravel into the concrete mixing station, then to install cement, mix evenly, and then mix with water.

(2) The mixing time of concrete can be determined by referring to the operation instructions of the concrete mixer. The mixing time is related to the type of mixer, slump and bucket capacity.

Concrete transportation

(1) Transport by mixer trucks specified in the standard.

(2) The transportation of concrete should be controlled within the prescribed time. If the transportation time needs to be prolonged, corresponding technical measures should be taken and verified by tests.
