Product Introduction

PCL Sand maker is also called impact sand maker, through impact sand maker, impact crusher, PCL sand maker, or straight sand maker. As an international advanced machine with high performance and low energy consumption, it plays an irreplaceable role among all equipment for fine crushing. It’s the most effective, practical and reliable sand making machine currently.

Working Principle

Materials go into PCL sand maker from the feeding inlet and are divided into two parts by separator. One part go into the speedy impeller and is sped up to hundreds of times the speed of gravitational acceleration and is cast away at the speed of 60-70 m/s from three evenly-distributed runners of the impeller. First, part of materials that fall free from all around the separator are crushed and then are pushed to the settled layer inside the cavity. Then, they are rebounded by the underlayer of materials to rush obliquely into vortex cavity which will be impacted, abraded, ground and crushed for twice or more.

The crushed materials are discharged from the lower discharging outlet. In the course of crushing, materials impact and crush voluntarily. Instead of being in direct contact with the hardware, they are impacted, abraded and crushed with the underlayer of materials which reduces wastes pollution and prolongs the period of abrasion. Inside the vortex cavity, air flow self-circulation is achieved dexterously which reduces the dust pollution.

Performance Characteristics

1.Simple and reasonable structure, self-impact crushing, fewer charges for use;

2.Unique bearing installation and advanced main bearing design endow the machine with features of heavy load and fast-rotating;

3.Fine crushing, coarse grinding.

4.Reliable and tight security device to guarantee the security of people and the machine;

5.Stable operation, low noise, energy-saving, high efficiency of crushing;

6.Small effect of about 8% moisture content of materials;

7.Less loss of abrasive components. All abrasive accessories adopt wear-resistant materials of high quality with long duration. A small amount is made of ultrahard wear-resistant materials which are featured by small size, lightness, and convenient renewal of accessories.

8.The self-circulation of air flow inside the vortex cavity reduces dust pollution;

9.The lining of materials inside the vortex crushing cavity together with the impeller greatly reduces the charges for abrasive components and maintenance workload. In the process of production, the stone stock can form a covering layer to protect the body which is durable to use.

10.Various ways of installation, movable installation;

11.The product is cubic with large bulk density and less iron pollution which can be made into stone shaping machine.
