1. Feeding equipment

Vibrating feeder: It is the most commonly used feeding equipment at present.

Performance: The feed hopper of the feeder needs to be compatible with the feeding equipment and is determined according to the user's feeding method. It can convert the intermittent feeding of dump trucks and loaders into continuous feeding of crushers, pre-screen before feeding, and screen out materials that the crusher cannot handle, which not only reduces the load fluctuation of the equipment, but also helps to extend the service life of the crusher.

2. Primary crushing

Jaw crusher: It is the primary crushing equipment commonly used in the current 1,000 tons per hour gravel production line.

Performance: The equipment adopts a deep cavity crushing design, with a large crushing ratio and excellent crushing effect. Among them, the upper limit of the feed particle size of the larger jaw crusher can reach 1 meter, and the output is quite high. And its models are rich and diverse, which can fully meet the diverse needs of different users in different production scenarios, and users can flexibly choose according to needs.

3. Secondary fine crushing

Cone crusher: This equipment is mainly used for secondary crushing of hard materials, such as pebbles, granite, etc. It has a selective crushing function and can accurately control the crushing force according to the transmission power, rotor quality and speed. At the same time, the equipment has a low operating cost, which can save money for users and improve economic benefits.

Impact crusher: It is mostly used for secondary crushing of soft and brittle materials, such as limestone, coal gangue, etc. It adopts the principle of impact crushing. There are more fine particles in the discharge, which is very popular among users in the 1,000 tons per hour gravel production line.

4. Three-stage sand making

Sand making machine: The sand making industry is developing rapidly. This equipment has the functions of sand making and shaping for materials, and its application is relatively wide.

Performance: The equipment can flexibly control the size of discharged particles by adjusting the rotor structure, speed and motor power. It has outstanding processing capacity, smooth and unobstructed material flow, can make sand and shape, and has significant results in optimizing and adjusting the finished sand particle size grade, which can well meet the requirements of different production for sand particle size.

5. Screening equipment

Screening machine: It is an indispensable equipment in sand production, with low price and many performance advantages.

Performance: First, it can reduce the processing volume of the subsequent crushing process (it can separate the materials with smaller particle size than the subsequent crushing discharge in the previous crushing discharge, and reduce the processing volume of fine-grained materials in the subsequent crushing discharge); second, it can screen and obtain some large-sized raw materials.

6. Sand washing equipment

Sand washing machine: In order to obtain higher quality machine-made sand, it needs to be washed with water.

Performance: This equipment can remove impurities in the soil and control the content of fine powder. The washed sand and gravel not only have improved quality, but also can be sold at a higher price in the market. Therefore, the use of sand washing machines in sand and gravel plants has become more and more common.
