Impact sander equipment details:

1、 Introduction

The impact sanding machine produced by Jinqiang Mining is a device used for manual sand making. According to the condition of materials and the requirements of finished products, it can be a reaction sanding machine, a cone sanding machine, or an impact sanding machine. According to the degree and scope of application in the industry, the impact sanding machine is the most widely used equipment, so the industry usually refers to the impact sanding machine as a sand making machine.

2、 The impact sanding machine is widely used in fine grinding operations of metal and non-metallic ores, cement, refractory materials, grinding materials, glass raw materials, building aggregates, artificial sand, and various metallurgical slag. The impact sanding machine is particularly suitable for medium hard, extra hard, and abrasive materials such as silicon carbide, emery, bauxite, magnesia, etc., and has more advantages than other types of crushers. The impact sanding machine is used in conjunction with hydraulic protection jaw breaker, and can handle various metallurgical slag. The impact sanding machine is suitable for construction sand and road sand.

Due to the excellent low wear characteristics of the impact sand machine, the sand making machine also adopts high wear resistance and secondary disintegration crushing production. In addition, since the product has zero pollution, the impact sander is suitable for the production of glass quartz sand and other high-purity materials. Within the production capacity of 10-500t/h, the impact sander can meet any production requirements.

3、 Advantages

1. The structure of the impact sanding machine is simple and reasonable, and the operating cost is low. Utilizing the principle of stone striking, with minimal wear and tear;

2. High crushing rate and energy saving of impact sanding machine; Has fine crushing and coarse grinding functions;

3. Less affected by the moisture content of the material, with a moisture content of around 8%;

4. The working noise of the impact sander is less than 75 decibels, with less dust pollution;

5. Suitable for crushing medium to extremely hard materials;

6. The product is cubic, with high stacking density and low iron pollution.

4、 Working principle of impact sanding machine

The material enters the crusher through the feed hopper, and is divided into two parts through the distributor. One part enters the high-speed rotating impeller through the middle of the distributor, and accelerates rapidly in the impeller. The acceleration can reach hundreds of times, and the Gravitational acceleration can reach hundreds of times. Then, the material is thrown out of the three uniform flow channels of the impeller at the speed of 60-70 m/s. First, it is crushed together with some materials that fall from the surrounding distributor, Then they impact the material lining inside the vortex support chamber together, which bounces back and obliquely impacts the top of the vortex chamber, changing its direction of movement and moving downwards. The material emitted from the impeller channel forms a continuous material curtain. This material is subjected to two or more chances of impact, friction, and grinding crushing in the eddy current crushing chamber. The crushed material is discharged from the lower discharge port. It forms a closed circuit with the circulating screening system, and can generally crush the material into less than 20 mesh after three cycles. During the entire crushing process, the materials collide with each other and are not in direct contact with metal components, reducing the friction of dust inside the materials and the friction from the lower discharge port, thereby eliminating the dust inside the machinery.
