Sand making machine is not only used for crushing hard materials, but also used for fine crushing and superfine crushing in artificial sand making, pre grinding cement, mining, refractory and other industries with different material properties.
Crushed materials such as granite, basalt, limestone, quartz stone, gneiss, cement clinker, concrete aggregate, ceramic raw materials, iron ore, gold mine, copper mine, corundum, bauxite, silica, etc. Here we introduce the advantages and working principle of the sand making machine.
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. The acceleration can reach hundreds of times of the gravity acceleration, and then it is ejected from the three uniformly distributed flow channels of the impeller at the speed of 60-70 meters/second.
First, a part of the materials collected from around the distributor will be impacted and broken, and then they will impact the material lining in the vortex branch chamber together, bounce back by the material lining, impact the top of the vortex chamber obliquely upwards, change its direction of movement, deflect downward, and the materials emitted from the impeller flow channel will form a continuous material curtain. Such a piece of material is impacted, rubbed and ground in the whirling crushing chamber twice or even several times.
The crushed materials are discharged from the lower discharge port. In the whole crushing process, the materials will impact and crush each other by themselves, not directly contacting with the metal components, but impact and friction with the material lining, which reduces pollution and extends the service time of the machine. The ingenious air circulation inside the whirling chamber eliminates dust pollution.
Advantages of sand machine:
1. The equipment has stable and reliable operation performance, simple process, simple, reasonable and compact structure, easy replacement of parts, and convenient maintenance.
2. Simple maintenance, convenient movement, high reliability, and tight safety devices ensure the safety of equipment and personnel.
3. Change the three-stage crushing into two-stage crushing, with large production capacity, long service life of hammers, environmental protection and energy conservation, which is widely applicable to the fine crushing of granite, basalt, cement clinker, quartz, emery, ore, iron ore, bauxite and other raw materials, overcoming the disadvantage that traditional sand making equipment is only applicable to soft rock raw materials.
4. It is widely used, with fine crushing and coarse grinding functions, and can produce sand and stone.
5. Unique structure, unique high chromium plate hammer, unique inertial impact balancing device, unique simple disassembly and maintenance window, unique bearing installation and spindle design make this machine have the characteristics of heavy load and high-speed rotation.
6. Stable operation, low working noise, energy saving and high crushing efficiency. It is less affected by the moisture content of materials, and the moisture content can reach about 8%.
