How to process mechanism sand from limestone

The process of limestone processing mechanism sand includes four main steps: raw material crushing, re-crushing, sand making and screening. 

1. Raw material crushing: first of all, the limestone raw materials through the jawbreaker and other crushing equipment for preliminary crushing, the large limestone crushed into a suitable particle size. 

2. Re-crushing: After preliminary crushing, the limestone particles are further crushed by the jawbreaker to make the particles finer. 

3. Sand making: the crushed limestone particles are processed by the sand making machine to make the mechanism sand and gravel that meets the requirements. 

4. Screening: In the process of sand making, the mechanism of sand and gravel is graded by screening equipment to get sand and gravel products that meet the specifications. 

In addition, the process of processing limestone into mechanism sand also involves the choice of equipment configuration. Jaw crusher is a commonly used crushing equipment in limestone processing, which has the characteristics of high efficiency crushing, robustness and durability. According to the water content of limestone, you can choose dry sand process or wet sand process. Dry sand process is suitable for the situation of low water content, while wet sand process is suitable for the situation of high water content, both processes can effectively improve the finished product rate and quality of mechanism sand.
