What equipment does a sand and gravel production line with an hourly output of 150 to 200 tons have?

A sand and gravel production line with an hourly output of 150 to 200 tons is a medium-sized production line that can meet the production requirements of most construction projects. The equipment configuration of such a production line mainly includes the following components:

1. Feeder: A feeder is used to evenly feed raw materials into the crushing machine. In a sand and gravel production line, it is usually an vibrating feeder.

2. Coarse crusher: The coarse crusher is responsible for crushing larger raw materials (such as granite, limestone, or river stone) into coarse particles. The common main crushers include jaw crushers, cone crushers, and impact crushers.

3. Secondary crusher: The secondary crusher further crushes the coarse particles from the primary crusher into finer particles. Common secondary crushers include cone crushers, impact crushers, and vertical shaft impact crushers.

4. Tertiary crusher (optional): If the final product size is very small, a tertiary crusher can be added to further crush the particles. Common tertiary crushers include roller crushers and ultrafine grinding mills.

5. Screening equipment: Screening equipment is used to separate the crushed particles into different particle sizes. In a sand and gravel production line, it is usually a vibrating screen or a circular vibrating screen.

6. Washing equipment (optional): If the final product requires high purity, a washing machine can be added to remove impurities and clay from the sand and gravel.

7. Conveyor belts: Conveyor belts are used to transport raw materials and products between different equipment components in the production line.

8. Control system: A control system is responsible for controlling and monitoring the operation of various equipment in the production line, ensuring smooth production and stable product quality.

The equipment configuration of a sand and gravel production line with an hourly output of 150 to 200 tons can be adjusted according to the specific production requirements and budget of the customer.
