How does the concrete batching plant work?

2017-04-17

Concrete mixing plant is divided into four parts: gravel feed, powder (cement, fly ash, bulking agents, etc.) to feed, water and feed additives, transmission and storage stirred their workflow shown in Figure 1. , the mixer control system power, into the human - machine dialogue operation interface, system initialization process, including recipe number, grade concrete slump, producers, etc. according to the amount of weight carried on each silo, weighing hoppers. detection, output material or material empty full signal, prompting the operator to determine whether to activate the control program starts stirring sand, stone belt motor fed into the metering hopper; open fly ash, cement tank valve, start the electromechanical screw conveyor ash cement to the metering hopper; open water reservoir and control valves admixture pool water and additives into the metering hopper metered meet the set requirements doo door open metering, mixing the ingredients into the mixer within already started to set. time to open the mixer door, into the concrete mixer had received material.

A concrete plant, also known as a batch plant or concrete batching plant, is a device that combines various ingredients to form concrete.
Some of these inputs include sand, water, aggregate (rocks, gravel, etc.), fly ash, potash, and cement.
There are two types of concrete plants: 
Ready mix plants (A ready mix plant combines all ingredients except for water at  the concrete plant. This mixture is then discharged into a ready mix  truck (also known as a concrete transport truck). Water is then added to the mix in the truck and mixed during transport to the job site) 
Central mix plants.(A central mix plant combines some or all of the above ingredients  (including water) at a central location. The final product is then  transported to the job site. Central mix plants differ from ready mix  plants in that they offer the end user a much more consistent product,  since all the ingredient mixing is done in a central location and is  computer-assisted to ensure uniformity of product.)
A concrete plant can have a variety of parts and accessories, including but not limited to:
Mixers (either tilt-up or horizontal or in some cases both), The center of the concrete batching plant is the mixer.
cement batchers,
aggregate batchers,
conveyors,
radial stackers,
aggregate bins,
cement bins,
heaters,
chillers,
cement silos,
batch  plant controls,
and dust collectors (to minimize environmental  pollution).
