1. Feeding: The raw materials are continuously and evenly sent to the primary crushing equipment by the feeder.

2. Crushing: In the crushing process of the ore, different crushers need to be configured at different stages. In the primary crushing stage, it mainly relies on the jaw crusher, whose powerful crushing force is suitable for ores of various hardness, as the first choice for coarse crushing. Entering the medium and fine crushing stage, it is necessary to flexibly choose according to the hardness of the ore: for soft ores, the impact crusher is the preferred choice for its high efficiency and energy saving; and for medium and hard ores, the cone crusher stands out for its excellent wear resistance and crushing efficiency.

3. Sand making: According to customer needs, a sand making machine can be configured after the production line is crushed, and the crushed stone can be further processed to produce the machine-made sand required by the customer.

4. Screening:

The sand and gravel that have been crushed or sand-made need to be graded by screening operations. The vibrating screen integrates screening and feeding functions, which can effectively control the specifications of the finished sand and gravel to ensure the quality of the finished product. Therefore, in the sand and gravel processing process, the vibrating screen plays a vital role.

5. Conveying: Belt conveyors are mainly used to transport materials and connect various equipment to make each equipment run in an orderly manner.

Principles of process design for sand and gravel crushing production line

1. Adapt to the times and be sure to reasonably configure equipment according to the work site of the production line to try to save energy and reduce time.

2. Configure equipment according to materials. Different materials require different equipment. A reasonable production line should be configured according to the characteristics of raw materials, production requirements, budget, etc.
