How to choose crushing equipment when investing in sand and gravel plants?

With the vigorous development of my country's high-speed railways, highways, and urban infrastructure construction projects, the demand for sand and gravel aggregates is increasing day by day, and the number of new sand and gravel plants is also increasing linearly. During this period, customers often asked how to choose sand and gravel plants. Regarding the problem of crushing equipment, SMMVIK company gives some suggestions for this problem, hoping to help customers who have doubts.

Common machine-made sand production lines are composed of feeding equipment, crushing equipment, screening equipment, and conveying equipment. According to the physical properties of the raw materials and the specifications and fineness requirements of the crushed products, the production line is often divided into two-stage or three-stage crushing.

Sand and gravel production line process equipment layout principle:

1. According to the actual needs of the job site, between the crushing processes at all levels, a buffer section and a storage site should be set up to ensure the normal operation of the equipment.

2. Sufficient stacking and shipping space should be reserved between products of different specifications, and necessary passages should be set up considering daily maintenance and hoisting requirements.

Sand and gravel production line crushing commonly used crushing equipment at all levels:

1. As a coarse crushing model, jaw crusher is generally suitable for crushing raw materials with high or medium hardness, and is not suitable for crushing viscous ores.

2. The cone crusher should be used as a medium and fine crushing model, and is generally suitable for crushing raw materials with high or medium hardness.

3. The impact crusher should be coarse, medium and fine crushing models with a large crushing ratio, and is generally suitable for raw materials below medium hard.

4. Vertical impact crusher can also be called sand making machine, such as 5X sand making machine and VSI series sand making machine , which discharge more fine materials and less needle flakes, and are generally suitable for the production of machine-made stone shaping machine-made sand.
