Aggregate Storage Methods for Concrete Batching Plants

Aggregate Storage Methods for Concrete Batching Plants Brief Introduction: The storage system of a ready-mixed concrete mixing plant can be of three types: underground type, star-shaped type and steel in-line bins. Aggregates are an important raw material of concrete. While we are familiar with huge silos for storage of powder materials, we are not necessarily clear about storage methods for ...

Concrete Batching and Mixing Plant Storage System

The storage system of a concrete batching and mixing plant consists of two parts: raw material storage devices (powder material silo, water tank, aggregate hopper, aggregate waiting hopper and additive tank) and concrete storage device (discharge hopper). It’s essential to guarantee storage quantities of raw materials in order to realize continuity and efficiency in production.
