Function of vertical shaft impact crusher (VSI5X sand making machine): The vertical shaft impact crusher (VSI5X series sand making machine) efficient centrifugal impact crusher, introducing the advanced German technology, are the new generation products owning many patents. It combined three crushing models and become main efficient crushing equipment in the machinery sand making industry.
Usage of vertical shaft impact crusher (VSI5X sand making machine): The vertical shaft impact crusher (VSI5X series sand making machine) can be widely used in metal and non-metal, building materials, artificial sand and all kinds of metallurgical slag crushing and shaping. This machine is suitable for Mons’ hardness less than nine of the brittle materials, does not for vicous material and stone containing more soil.
Working Principle of vertical shaft impact crusher (VSI5X Crusher): The Centrifugal impact crusher uses high-speed movement of materials with their own friction to crushing. Centrifugal impact crusher not only crushes, but also shapes the stone. According to the feeding pattern, there are two working farms: completely central feeding and central feeding with cascade feeding ; according to the crushing resistance and corrosiveness of the materials, there are two working forms: crushing between materials and crushing between materials and liners. So totally there are four kinds of the working forms. Working principle for central feeding with cascade feeding and crushing between materials. The materials enter the machine though the feed hopper, and fall into the material tray through the material distribution plate, and be divided into two parts. One part of material enter the high speed rotated rotator through the center of the distribution tray and are accelerated quickly inside the impeller, and then are thrown out through flowing chute of the impeller at high speed, firstly are crushed by impaction with another parts of the materials falling from the distribution tray, and then together they are impacted to the material lining of the crushing chamber, after that they are rebounded from the material lining up to the top of the crushing chamber, and then change the moving direction from upwards to downwards and formed continuous material screen. In this way, one piece of the material will be impacted, crushed, and grinded many times in the crushing chamber.
The broken materials depart from the crushing chamber under the gravity action and fall into the lower-part shell and are discharged by the discharge hopper. Upper and lower impact protecting pieces are installed on the wall of the crushing chamber to protect the body shell from wearing. Its characteristic is that the materials are accelerated by the rotator, and half of the materials are thrown out by the energy got from the rotator and then crushed, impacted, grinded with the materials lining or the materials crushed by their own high speed rotated impact, which is called “crushing between materials”.
