I. VSI Sand Maker The working principle of VSI Sand Maker can be divided into "stone to stone" and "stone to iron" crushing principles according to the feeding method. Gravel adopts waterfall diversion system, which divides the material into two paths, one path enters the inner cavity of the impeller rotating at high speed, the other path enters the inner cavity of the equipment, and the latter two paths of materials collide strongly in the impeller area to form gravel; "Strike while the iron is hot" means that all materials are introduced into the impeller cavity, accelerated by the impeller and thrown out, and collide with the metal impact plate on the inner wall of the equipment to achieve the crushing effect.
Second, the advantages of VSI sand maker 1, the crushing ratio of VSI sand maker equipment can reach more than 50, which is greater than that of traditional sand maker equipment;
2. When the VSI sand maker breaks the material, it will break along the fragile layer of the material. Most of the broken materials are cubic, and the needle content is low, which is about 5% lower than that of ordinary sand makers.
3.VSI sand making machine has selective crushing effect, which is suitable for both soft and hard materials. The particle size after crushing is smaller than that of important materials, and the particle size of materials with small specific gravity is larger after crushing;
4. The crushing cavity of 4.VSI sand maker is deep, which can make full use of impact force to crush materials, and the produced machine-made sand has uniform particle size and good particle shape.
VSI sand making machine is a common sand making machine in domestic sand and gravel industry, and it is also an advanced technology and widely used sand making machine. Compared with the same type of sand making machine, VSI sand making machine has better sand grain size, higher output and lower use cost, and is a common equipment for producing machine-made sand aggregate.
