Product Description
Application of Sand Making Machine
Sand making machine also named sand maker is a kind of advanced stone-crushing equipment in home and abroad with high-efficiency, which is designed by adopting the tone-beating-stone theory and technology from Barmac Company of America.The Sand making machine is widely used for crushing hard and brickle materials including various minerals, abrasive material, refractory material, cement, quartz, iron ore, etc.Sand maker is specially suitable for making sand for buildings, road building. The HX Sand making machine(sand maker) consists of inlet, material-scattering device, whorl crushing chamber, impeller, main shaft, base, transmission drive, motor, etc.
Working process: Materials fall from the upper part of the machine to impeller which rotates at a high speed. Under great centrifugal force, they hit materials scattered around the impeller. After hitting each other at a high speed, there forms a vortex between impeller and shell. Materials hit and abrase each other for several times, finally smaller pieces come out through downside outlet, then go to vibrating screen which controls the size of final product.
Working principles of sand making machine: Materials are transferred to sand making machinery from hopper, then they fall into two parts by material-scattering device. One part falls to the impeller which rotates at a high speed from material-scattering device. In the impeller, materials rotate at even higher speed, and their acceleration is as big as hundreds of acceleration of gravity, then they are thrown out through three passages of impeller at a speed of 60-70 meters/second. They firstly hit part of materials falling from material-scattering device, then strike with materials inside the cavity, and rebounded by underlayer to top of cavity, thus its direction of motion changes to downward, then materials fall from the impeller passage form a continuous fall. Then one piece of stone will be hit, abrased for twice or more times in the crushing cavity. The closed circuit forms, usually materials can be crushed to smaller than 20 mesh after three times in the circulation. The crushed materials will be discharged from outlet. They hit each other but will not hit metal parts of equipment directly because of material underlayer, thus the pollution is less, and service lifetime of equipment is prolonged. The cute air current self circulation in the cavity removes the powder pollution.
Features of Sand Making Machine
Working characteristics of sand maker:
1. Simple structure and low cost owning to sand maker;
2. High efficiency, low consumption and high crushing ratio;
3. Suitable for fine crushing and crude grinding;
4. Slightly influenced by moisture content of material and the max moisture content is 8%;
5.Suitable for crushing mid-hardness and extra hard materials (like corundum, agglomeration aluminium, etc.);
6. Cubic shape of final products and low iron pollution;
7. Impeller and material layer in the crushing cavity can prolong service lifetime of easy-worn parts and avoid maintenance;
8. Easy operation and installation;
9. Low working noise (lower than 75 decibel);
10. Light weight and various ways of installation, and portable installation, etc.
