In recent years, with the advancement of urbanization and economic development, more and more buildings, roads and railways have been developed and constructed, and the demand for construction sand is increasing. People have turned their vision to cobblestone, quartz stone, on some stone materials such as granite and basalt, the mechanism sand industry is developing rapidly, and the mechanism sand production lines across the country are increasing. Relative to natural sand, the sand particles made of stone have a cubic shape, the content of stone powder is between 3% and 10%, and the fineness modulus is moderate. The concrete has more stable quality and higher strength. If you want to get high-quality sand and stone, you must start with the crusher equipment for crushing ore. The sand making machine is the third-level crushing equipment of the machine-made sand production line.
The stones mentioned here are our common pebbles, river pebbles, quartz stones, granite, basalt, limestone and other ores. There are many types of sand making machines that turn stones into sand. The quality of sand produced by different types of sand making machines is also different. It is generally recommended that you choose the PLS series vertical impact crusher. The stone material is finely crushed to complete the sand making product. And it has the effect of shaping, and has the function of optimizing and adjusting the particle size gradation of the finished sand.
Realize the free conversion of the double crushing principle of "stone beat stone" and "stone beat iron"
The work of PLS series sand making machine is to use the "stone beat stone" and "stone beat iron" combination of two sand making principles to crush ore, which solves the multi-purpose problem of one machine and greatly reduces the damage of wearing parts. In order to adapt to more working conditions and the requirements of crushing and shaping different materials: artificial sand, crushed stone and shaping, abrasive materials, etc.
Environmental protection standards, less dust
The closed design is adopted. During the whole crushing process, the materials impact and crush each other, and do not directly contact with the metal components in the equipment. Instead, it collides with the lining of the material, crushes and crushes, and the clever airflow inside the vortex chamber self-circulates, with less dust pollution.
Simple operation and high intelligence
The equipment can also be optionally equipped with a thin oil lubrication system and a PLC automatic control and monitoring system, which can timely monitor the feed volume, current, oil temperature, spindle temperature, vibration protection and other functions.
Directly hit the sand site of PLS sand making mechanism
Material: pebbles
Production capacity: 175t/h
Finished material: 0-5, 5-10, 10-20, 20-31.5mm
Equipment: JC series jaw crusher + HPY series multi-cylinder hydraulic cone crusher + PLS series vertical impact crusher + YKR series vibrating screen + ZKR series vibrating screen + XL series spiral sand washing machine
Process design: The aggregate of this gravel production line adopts three-stage crushing. Before entering the raw material silo, the river pebble raw materials are sieved by a bar screen. The sieved raw materials enter the pre-screening. After initial crushing, the crushed material enters the intermediate crushing adjustment silo. The secondary crushing is completed by the cone crusher. The material from the cone enters the first screening workshop for sieving. The material larger than 31.5mm is returned to the cone crusher to be crushed again. A closed loop is formed, and the materials smaller than 20mm enter the vertical impact crusher for shaping and sand making. The materials are screened by the second screening workshop, and the screened materials are transported to various finished product piles by a belt conveyor.
