The equipment required for a 300-ton sand production line is mainly the following:

1. Feeding equipment

- Vibrating feeder: such as GZD1100*4200 vibrating feeder, used to feed raw materials into the crusher evenly and continuously to ensure the stable operation of the production line. While feeding, the vibrating feeder can also pre-screen the material to remove impurities.

2. Crushing equipment

- Jaw crusher: such as PE600*900 jaw crusher or YZ106 European version jaw crusher, used for the initial crushing of raw materials, breaking large pieces into smaller particles. Jaw crusher is famous for its simple structure, easy maintenance and high crushing ratio.

- Impact crusher: such as PF1214 impact crusher, used for secondary crushing of materials after primary crushing to further improve crushing efficiency. Impact crusher has high crushing efficiency and uniform product particle size.

- VSI Sand Making Machine: such as VSI-8518 VSI Sand Making Machine, used for fine crushing and sand making to produce the required sand and gravel particles. Vertical shaft impact crusher has strong crushing capacity and good particle shape.

3. Screening equipment

- Vibrating screen: such as 2YK1545 vibrating screen, 4YK1548 vibrating screen, used to screen crushed materials, separate particles of different sizes, and obtain the required sand and gravel products. Vibrating screen is famous for its high screening efficiency and accuracy.

4. Sand washing equipment

- Sand washing machine: such as ZH1500-9 spiral sand washing machine, is used to clean the sand and gravel particles after screening, remove dirt, impurities, powder, etc., and make the particles purer. The sand washing machine uses water flow to clean the sand and gravel to achieve the purpose of cleaning.

5. Auxiliary equipment

- Belt conveyor: used to transport materials between different equipment to achieve automated and continuous production. The number and length of belt conveyors depend on the actual site conditions.

In summary, a 300-ton sand and gravel production line requires vibrating feeders, jaw crushers, impact crushers, vertical shaft impact crushers, vibrating screens, sand washers, belt conveyors and other equipment. These equipment work together to complete the crushing, screening and cleaning of sand and gravel to produce the required products. The specific equipment configuration and selection need to be comprehensively considered based on factors such as raw material properties, production scale, and product requirements.
