River pebble sand crusher

Application Area

Used in public buildings, paving (long cobblestones can prolong life), garden art, etc. Cobblestones provide high quality materials for water purification, sewage treatment, electric power, garden and other projects, as well as raw and auxiliary materials for ceramics, precision casting, papermaking, spray grinding, chemical industry, monocrystalline silicon and national defense.

Introduction To Materials

River pebble is a kind of pure natural stone material, which is taken from the sand and stone mountains generated by the ancient riverbed uplift after the crustal movement of thousands of years ago. It has experienced the impact of mountain flood and the constant extrusion and friction in the process of moving water. In the evolution of tens of thousands of years of vicissitudes of life, they have experienced the movement of waves and water, and lost their irregular edges and corners due to the collision and friction of gravel. Finally, they become river pebbles with strong quality, bright color and simple, resistant to pressure, abrasion and corrosion, which is an ideal green building material.

Material Handling Process

Material from the feed hopper to impact crusher, the distributor will material is divided into two parts, part from the distributor in the middle to high speed rotating impeller, the impeller is rapidly accelerating, impingement cobble sand making machine speed can reach hundreds of times the gravitational acceleration, and then at the speed of 60-70 - m/s from three uniform mass ejection of the flow passage of impeller to go out, first with received by distributor around the drop impact part of the material, and then hit with vortex cavity lining material and be lining material rebound, oblique upward shocks to the top of the vortex chamber, and change the direction of movement, deflecting downward movement, The material emitted from the impeller runner forms a continuous material curtain. Such a piece of material is subjected to two or even many probability impacts, abrasions and grinding crushing in the vortex crushing chamber. The crushed material is discharged through the lower discharge port. In the whole process of crushing, the materials break each other by themselves, not in direct contact with the metal components, but with the material liner impact, friction and crushing, which reduces the Angle pollution, prolong the mechanical wear time. The ingenious air circulation in the vortex cavity eliminates dust pollution.
