Vertical shaft impact crusher is a necessary sand making equipment in the process of sand making. It uses the working principles of "stone hitting stone" and "stone hitting iron" to complete the crushing process through the high-speed rotation of the impeller. The equipment has strong practicability and large throughput. , The finished product is of excellent quality and widely used. When the crushed material is not ideal, what are the factors that affect the effect of the vertical shaft impact crusher?

1. The hardness of the material: the harder the material is, the more difficult it is to make sand, and the more serious the wear of vertical shaft impact crusher is. The speed of sand making is slow and the ability is low. Therefore, we need to pay attention to the selection of materials.

2. The composition of the material: the more fine powder contained in the material before the vertical shaft impact crusher, the more it will affect the sand making, because these fine powders are easy to adhere and affect the conveying. Therefore, materials with a high content of fine powder should be sieved once in advance. Screen out the fine powder from the material as much as possible, so as not to affect the normal operation of the impact crusher.

3. The fineness of the material: the fineness requirement is high, that is, the finer the material required for sand making, the smaller the sand making capacity. This aspect depends on the specific requirements. If there are no special requirements, generally the fineness of the material can be set to medium and fine.

4. The viscosity of the material: that is, the greater the viscosity of the material, the easier it is to adhere. The materials with high viscosity will adhere to the inner wall of the sand making chamber in the vertical shaft impact crusher. If they cannot be cleaned in time, the working efficiency of the impact crusher will be affected, and in severe cases, the normal operation of the vertical crusher may be affected. Therefore, when selecting materials, we must pay attention to the viscosity of the materials is not easy to be too large.

5. Humidity of the material: When the moisture content in the material is large, the material is easy to adhere in the vertical shaft impact crusher, and it is also easy to cause blockage during the feeding and conveying process, resulting in the reduction of the sand-making capacity. To solve this problem, first of all, the humidity of the material should be strictly controlled when the material is selected. If the humidity of the selected material is too high, sunlight or air drying can be used to reduce the percentage of moisture in the material.
