The simple process of limestone processing into machine-made sand is as follows:

1. Coarse crushing

The jaw crusher is the first step in limestone processing, responsible for continuously and evenly feeding large pieces of limestone into the crushing chamber. Through the reciprocating motion of the movable jaw, a strong extrusion force is applied to the limestone, causing it to break into smaller-sized stones, laying the foundation for subsequent processing.

2. Medium and fine crushing

The stone particle size after coarse crushing is too large and needs to be further refined. At this time, the cone crusher or impact crusher comes on the scene. They perform medium and fine crushing to reduce the stone particle size to the acceptable range of the sand making machine, ensure the smooth progress of the sand making process, and improve the overall production efficiency and product quality.

Among them, the cone crusher is suitable for the crushing of hard materials, and the impact crusher is suitable for the crushing of medium and brittle materials. Just choose according to the specific material.

3. Sand making

The finely crushed limestone is screened by a vibrating screen to select the limestone that meets the sand making requirements and enters the sand making machine, which makes sand and shapes it. The limestone that does not meet the requirements is returned to the previous level for further processing until it meets the feed requirements.

4. Cleaning process

The sand washing process can effectively reduce the impurity content in the sand and gravel aggregate, improve the cleanliness of the sand and gravel, and expand sales. The main equipment used in this process is a spiral sand washing machine or a wheel sand washing machine.
