Why do we need sand and gravel processing sanders in industrial production? The mechanical sand we usually call is that the large stone is polished and sieved by grinding equipment, and the product particle size meets certain technical indicators. The machine-made sand produced by the sand-making production line has many excellent properties that cannot be compared with natural sand. The sandstone sand making machine is specially designed to provide high quality gravel aggregate for the foundation construction of highways, dams, etc. It is an ideal equipment for artificial sand making and stone shaping.
The sand and gravel processing sand making machine is composed of five parts: box body, rotor, hammer head, counter-attack lining plate and sieve plate. The working principle is to use the hammer head inside the grinding machine to impact and polish the original material, and the boring entry after polishing is completed. In the lower part of the rotor, the material is pulverized by the hammer head to the grinding plate for the second time. The hammer head is continuously impacted by the animal material and pulverized during the high-speed rotation. When the sand and gravel processing sanding machine is ground to a certain extent, the material enters the sieve plate under the impact force, and the particle size is smaller than the hole above the sieve plate, then the polished material is discharged through the sieve plate, which is larger than the diameter of the sieve plate hole. The coarse-grained material will remain on the sieve plate and continue to be struck and ground by the hammer until it is sanded to the size that can be screened through the sieve plate. The material passing through the sieve plate is directly passed through the sieve hole and then transported to the gravel processing. Sand machine discharge port.
Performance characteristics of sandstone sand making machine:
1. The structure is simple and reasonable, and the running cost is low;
2. It has the functions of fine crushing and coarse grinding, high energy consumption and high crushing rate.
3. equipment volume Xiao impeller self-lining wear filial operation is simple, easy to install and maintain.
4. It is affected by the moisture content of the material, and the water content can reach 8%.
5. with plastic function, the product is cubic, bulk density, iron pollution
6. more suitable for crushing medium hard, extra hard materials.
7. A small amount of wear-resistant parts are made of special hard and wear-resistant materials, which are light in weight and easy to replace.
8. working noise is less than 75 decibels (dstrong level), less dust pollution.
