Pebble sand making machine

Pebble sand making machine (also known as pebble sand making machine). As a kind of pure stone, the river pebble is taken from the sand and stone mountain produced by the ancient riverbed uplift after the crustal movement tens of thousands of years ago, and has experienced the continuous extrusion and friction in the process of mountain flood impact and water transport. In the course of tens of thousands of years of vicissitudes, they have been subjected to the movement of waves and water, and have lost their irregular shape by the friction of gravel collision. The quality of the pebble is hard, the color is bright and simple, and it has the characteristics of pressure resistance, wear resistance and corrosion resistance. Pebble sand making machine has three modes of crushing, sand making and shaping in one, a model of combining professional crushing technology with mechanical manufacturing, which is the full embodiment of new technology and new technology. Widely used in river pebbles, mountain stones (limestone, granite, basalt, diabase, andesite, etc.), ore tailings, stone debris artificial crushing sand.

Working principle of pebble sand making machine:

The material enters the river pebble sand making machine by the hopper, and is divided into two parts by the distributor, one part enters the high-speed rotating impeller by the middle of the distributor, and the speed of the river pebble sand making machine can reach hundreds of times the acceleration of gravity, and then it is thrown out from the wheel at a high speed. First, it shocks and breaks with a part of the material collected and falling around the distributor, and then it impacts the material lining layer in the vortex branch cavity together. Rebound by the material lining layer, oblique upward impact to the top of the vortex chamber, and change its direction of movement, deflection downward movement, the material emitted from the impeller flow path to form a continuous material screen. Such a piece of material is subjected to two or more chances of impact, friction and grinding in the eddy crushing chamber. The work of the pebble sand making machine is to break the ore with the principle of stone beating stone, with selective crushing effect, and the particle size of the broken product is more uniform, the shape is mostly cube, and the broken material is discharged from the lower discharge port. In the whole crushing process, the material is broken by impact with each other, not in direct contact with the metal components, but with the material lining impact, friction and crushing, which reduces the Angle pollution and extends the mechanical wear time. The ingenious self-circulation of air flow inside the vortex chamber eliminates dust pollution.

Internal structure of river pebble sand making machine

Advantages of pebble sand making machine:

1, uniform grain shape, large production capacity, small supporting power, low noise, smooth operation.

2, in the production process, stone can form a protective bottom, fuselage without wear, more durable.

3, easy to wear parts made of extra hard wear-resistant material, small size, light weight, easy to replace parts.

4, high degree of automation, automatic detection and alarm system, reliable.

5, air self-circulation system, greatly reduce the exhaust air volume, reduce dust, protect the environment.

6, finished particle size in line with sand standards.
