What is the composition and workflow of a concrete mixing plant?

The concrete mixing plant mainly consists of five major systems including the mixing host, material weighing system, material conveying system, material storage system, and mixing plant control system, as well as other ancillary facilities.

Concrete mixers are divided into forced mixing and self dropping mixing according to their mixing methods. Forced mixer is currently the mainstream used in mixing plants both domestically and internationally. It can mix various types of concrete such as flowable, semi dry hard, and dry hard. Self falling mixing machines are mainly used to mix flowable concrete and are currently rarely used in mixing plants.   

Forced mixers are divided into main shaft planetary mixers, single horizontal shaft mixers, and double horizontal shaft mixers according to their structural forms. Among them, the comprehensive performance of the double horizontal shaft forced mixer is particularly better. The company's series of mixing plants all use double horizontal shaft forced mixers.

A concrete mixing plant is a fully automatic concrete mixing equipment consisting of feeding, mixing, electrical control, and steel structural components, suitable for medium to large-scale construction sites, prefabrication plants, and commercial concrete production plants.

The concrete mixing plant consists of a sand and gravel batching system, a material conveying system, a measuring system, a mixing device, a water supply system, an additive supply system, an air circuit system, and an electrical control system. The process flow is as follows: the cement and fly ash in the cement silo enter the corresponding weighing hopper through a screw conveyor, and the sand and stone in the sand and stone hopper are put into the horizontal belt conveyor below through the arc-shaped door at the bottom of the silo for weighing, and then input into the sand and stone storage hopper through the horizontal belt conveyor and inclined belt conveyor; Water and additives are pumped into their respective weighing buckets by electric pumps. After the ingredients are mixed, they enter the mixer for mixing. The mixed concrete is directly discharged into the concrete delivery truck through the concrete collection hopper.

The concrete mixing plant is stable and reliable, with accurate weighing, short mixing time, and good quality. It has two operation modes, manual and automatic, with a high degree of automation. It can store various concrete formulas and is equipped with a printer for easy production management.
