In the construction of roads and railways, stones are usually used, but the stones purchased are relatively large, and the construction of roads and railways requires smaller stones, which is what we often call fine sand. Therefore, before the stones such as oil, it is necessary to make sand first, that is, break the large stones into small ones. The equipment that can achieve this effect is the sand machine, which turns the large stones into fine sand through a series of operations. So what is the working principle of the sand making machine? How does it do it? In addition, what are the performance characteristics of the sand making machine? Next, Xiaobian will introduce it in detail. Let's take a look with Xiaobian.

Working principle of sand making machine:

The material enters the sand making machine from the feed hopper, and is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller. Its acceleration can reach hundreds of times the gravitational acceleration, and then it is thrown out from the three evenly distributed flow channels of the impeller at the speed of 60-70 M / s. first, it is impacted and broken with a part of the material collected and dropped around the distributor, Then they impact on the material lining in the vortex branch chamber together, rebound by the material lining, impact the top of the vortex chamber obliquely upward, change its movement direction, deflect and move downward, and the materials emitted from the impeller channel form a continuous material curtain.

Such a piece of material is subjected to two or more times of probability impact, friction, grinding and crushing in the vortex crushing chamber. The crushed materials are discharged from the lower discharge port. In the whole crushing process, the materials impact and crush each other without direct contact with metal components, but impact and friction with the material lining, which reduces angular pollution and prolongs the mechanical wear time. The ingenious air flow self circulation inside the whirling chamber eliminates dust pollution.

The materials fall into the feeding hopper, enter the high-speed rotating rotor through the central feeding hole, and then are fully accelerated and thrown out through the launching port. First, they collide with a part of the materials that fall freely after rebound, and then impact on the vortex material lining (or counterattack block) in the surrounding vortex chamber together. First, they are bounced to the top of the crushing chamber, and then deflect to move downward, and collide with the materials emitted from the impeller channel to form a continuous material curtain, Then it is discharged through the lower discharge port.

Performance characteristics of sand making machine:

1. The sand making machine has simple structure and low cost.

2. The sand making machine is efficient and energy-saving, with high crushing efficiency.

3. The sand making machine has the functions of fine crushing and coarse grinding.

4. The sand making machine has a strong ability to pass through non broken materials and is less affected by the moisture content of the materials, which can reach 8%.

5. The sand making machine can crush medium hard and extra hard materials (such as corundum, sintered bauxite, etc.).

6. The products of the sand making machine are cubic and have little iron pollution.

The above is about the working principle and performance characteristics of the sand making machine. From the above content, we can see that the sand making effect of the equipment should be good, otherwise there will be no manufacturers to use it. If you need to make fine sand in the future, you can choose it.
