The new type of sand making machine (vsi vertical shaft impact crusher) is suitable for crushing soft or medium hard and extremely hard ore materials with hardness not higher than 320pa. Sand making machine is widely used in large, smelting, building materials, highway, railway, water conservancy and chemical industry and many other departments.
Sand making machine consists of seven parts: feed, distributor, vortex crushing chamber, impeller experience, spindle assembly, base drive device and motor.
The material falls into the feed hopper, enters the rotor of high speed rotation through the central feed hole, and then it is fully accelerated and thrown out through the launching port. Firstly, it impacts with a part of the material falling freely after rebound, then it impacts on the vortex material lining (or counter block) in the surrounding vortex cavity, and then bounces back to the top of the crushing cavity, then turns to the downward motion, and then it is launched from the impeller channel. The material impact forms a continuous material curtain, and finally is discharged through the lower discharge port.
During the whole crushing process, the materials are impacted and broken by themselves, not directly contacting with metal elements, but are smashed by impact and friction with the material lining, which reduces pollution and prolongs the mechanical wear time. In addition, the smart air flow inside the vortex chamber circulates itself, eliminating dust pollution.
1. Sand making and shaping: the impeller cavity is deep, the stone throughput is increased by 30%, the output is large, and the shaping effect is certain. The finished sand has good grain shape, reasonable gradation and adjustable fineness modulus;
2. Durable and simple maintenance: the core parts are elaborately made and more durable, with a life extension of 1.5-3 times. At the same time, the hydraulic cover can be opened, which is more convenient for users to view and repair, and the daily maintenance is simple;
3. A variety of crushing standards: adopt the crushing principle of "stone striking stone and stone striking iron", small floor area, simple sand making, combined throwing head, which piece is worn and replaced by which piece, reduces the use cost by 30%;
4. Environmental protection, green and energy saving: the air flow inside the vortex chamber is self circulating, with less dust and low noise. At the same time, brand motor is selected, which has sufficient kinetic energy and is more energy-saving.
In addition, the sand making machine can also be directly mounted in the mobile crushing station to form a mobile sand making vehicle, which is more flexible and convenient, and can adapt to the requirements and standards of more different users.
