work order for aggregate crusher plant

The mined aggregate is much larger than the final product, so crushers are used to break it down into smaller particles. The aggregate crushing plant design should be tailored to different production requirements (raw material, capacity, and output size). Generally, the multi-stage crushing principle is adopted. 1. Primary crushing

The raw aggregate is first fed by a vibrating feeder and enters the primary crusher for coarse crushing, where it is reduced to a size of 10–350 mm. The primary crusher can be a jaw crusher, a gyratory crusher, or a hammer crusher. A jaw crusher is generally used. 2. Secondary and tertiary crushing

In a four-step crushing process, the gyratory crusher is usually the fourth crusher. The choices for the second or third crusher are cone crusher, gyratory crusher, or impact crusher. A jaw crusher can be put at the first crushing sector, acting as the primary crusher, which processes material larger than 500mm.

The feeding size of the first crusher in a Crushing Plant is under 100mm. The second crusher has a feeding size of 5-200mm, and the third crusher has a feeding size of 5-100mm. After analyzing the processing flow and aggregate size, the determination of the crusher machine should be taken into consideration next. The crushing effect varies with the type and model.

3 Screening: The crushed material passes through a series of screens to separate it into different sizes. 4 Washing aggregate: Aggregates are washed to remove impurities to ensure the quality and durability of the final product. Aggregate equipment is crucial in aggregate production.

The crushing process is determined by the requirements, cost, and profit. In practice, there is usually a minimum of three crushing processes. Aggregate that is crushed one or two times usually does not achieve the required effect in terms of size or shape. The higher the crushing times, the higher the cost.
