The crushing and sand making production line is an equipment system used to produce sand and gravel for construction. This system processes large pieces of raw materials (such as ore, river pebbles, limestone, etc.) into sand and gravel aggregates that meet construction standards through multi-stage crushing and screening.
The main components and functions of the crushing and sand making production line:
- Raw material warehouse: stores raw materials to be processed to ensure continuous operation of the production line.
- Vibrating feeder: Evenly transports raw materials to the crusher to prevent damage to the crusher due to uneven feeding.
- Crusher:
- Jaw Crusher: Used for primary crushing to break large pieces of raw material into medium-sized stones.
- Impact crusher/cone crusher: used for medium and fine crushing to further crush the initially broken stone to the required particle size.
- Sand making machine: further crush the finely crushed materials into particles that meet the construction sand standards.
- Vibrating screen: Screens the crushed materials and divides them into finished sand and gravel of different specifications.
- Conveyor belt: connects various equipment to form a continuous production process and transports finished sand and gravel to the finished product pile.
- Sand washing machine (optional): used to clean the finished sand and gravel, remove soil and impurities, and improve the quality of the finished product.
- Dust removal equipment (optional): Control dust generated during the production process and protect the environment.
- Electronic control system: controls the operation of the entire production line, including equipment start, stop, alarm and other functions.
Process of crushing sand making production line
- Primary crushing: The raw materials enter the jaw crusher through the vibrating feeder for primary crushing.
- Medium and fine crushing: The primary crushed materials enter the impact crusher or cone crusher through the conveyor belt for further crushing.
- Sand making: The finely crushed materials enter the sand making machine to form sand particles.
- Screening: The sand-making materials are divided into different specifications of finished sand and gravel through a vibrating screen.
- Cleaning (optional): After cleaning with a sand washing machine, clean finished sand is obtained.
- Stacking of finished products: Transport the finished sand and gravel to the finished product pile through a conveyor belt.
The crushing and sand making production line is widely used in construction, highways, railways, water conservancy and other engineering projects, and can efficiently produce sand and gravel aggregates that meet standards to meet market demand. Choosing appropriate equipment and scientific configuration solutions can greatly improve production efficiency and product quality.
