This sand production line is a kind of typical process flow

Typical configurations of sand production line include: coarse crushing equipment (such as jaw crusher), medium and fine crushing equipment (such as vertical impact crusher, sand making machine), screening device (such as circular vibrating screen), and cleaning equipment (such as screw sand washer or bucket wheel sand washer).

Characteristics of sand production line:

1. reasonable combination of equipment: close connection between the equipment, smooth material flow.
2. Excellent particle shape: the finished sand is cubic, with reasonable particle grading and good bonding performance.
3. Controllable fineness modulus: the fineness of sand can be adjusted according to the demand to meet different uses.
4. Strong abrasion resistance: the wear-resistant parts of the core equipment are made of high hardness materials with long service life.
5. high degree of automation: support PLC centralized control, easy operation, stable operation.

Advantages of sand production line:

1. high efficiency of sand making: Vertical impact crusher has the dual function of shaping and crushing, which improves the efficiency of sand making.
2. High sand rate: reasonable screening and closed-circuit recycling system can improve the rate of finished products.
3. Environmental protection and energy saving: it can be equipped with dust removal and noise reduction system to reduce the impact on the environment.
4. Wide range of application: it can deal with a variety of hardness and types of raw materials, including hard rock, soft rock and slag.
5. excellent cost control: low energy consumption of the production line, low labor input, moderate maintenance costs, outstanding economic benefits.

The working principle of sand production line:

1. crushing stage: large materials are fed into the jaw crusher through vibrating feeder for preliminary crushing, forming medium-sized materials suitable for further processing.
2. screening stage: the crushed material is screened by circular vibrating screen, the coarse material is returned to be re-crushed, and the fine material goes into the next process.
3. sand making and shaping: qualified materials enter the vertical impact crusher, the materials are accelerated in the high-speed rotor and impacted with the liner plate to complete the sand making and shaping process.
4. sand washing stage: the sand is cleaned by screw sand washer to remove impurities and dust and improve the cleanliness of sand.
5. Finished product output: the cleaned mechanism sand is transported to the finished product stockpile area through the belt, completing the whole sand making process.

Application areas of sand production line:

1. Construction industry: used in the processing of sand and concrete aggregate for high-rise buildings.
2. Transportation infrastructure: widely used in highway, high-speed rail, airport runway and other projects.
3. Municipal engineering: covering the demand for aggregate in city roads, sidewalks, and sewerage projects.
4. Water conservancy project: applicable to the supply of aggregates in the construction of dams, canals and artificial lakes.
5. Mine tailings utilization: processing waste slag or tailings into recycled sand, turning waste into treasure.
6. Sand and gravel mixing plant: providing high quality mechanism sand for commercial mixing plant, replacing natural sand source.
