　　Efficient system sand machine function introduced:

　　1. The feed hopper

　　The appearance of feed hopper is a handstand trustum of a pyramid body, inlet set wear ring, from feeding equipment into the crusher.

　　2. The distributor

　　Distributor is installed in the upper portion of the eddy current crushing cavity, the role of the distributor

　　is the material is divided into two parts, part of the material by the center tube directly into the impeller, others by distributor edge to the vortex chamber, and flung round of high-speed material to form a "stone hit stone" broken effect, no increase in power consumption, increase production capacity, improve the efficiency of crushing.

　　3. The eddy current crushing cavity

　　Vortex structure of the crushing cavity shape for similar cylinder of high wear-resisting material of annular space, the impeller in the eddy current crushing cavity high-speed rotation, eddy current can reside material crushing cavity, the formation of lining materials, the material of the broken process occurred in eddy current crushing cavity, the lining material crushing effect and eddy current crushing cavity wall separated between the crushing effect is limited to the material, since the lining. Observe hole is impeller passage launch mouth wear resistant block and eddy current crushing cavity liner wear, crusher work observation holes must be closed.

　　4. The impeller

　　Impeller structure is made of special materials for a hollow cylinder, mounted on the spindle assembly upper shaft head, with the taper sleeve and key link transmission torque, high-speed rotating impeller type, high efficiency of the key parts of the sand making machine. Material from the center of the impeller on the part of the device into the feeding tube into the center of the impeller, the impeller center cone fabric would materials uniform distribution to different launch of impeller flow channel, the launch port exports, equipped with wear-resistant block made of special material, can be replaced. The impeller material will speed up to 70-75 m/s mass ejection out, first with the organ of material formed the impact, and then to impact on eddy current lining material and lining again hit. On points between cone and wear resistant block is equipped with material, obscene but, protect the impeller from the wear and tear.

　　5. The spindle assembly

　　Spindle assembly installed on the base of power from the motor used to pass through a triangle belt supporting impeller rotation movement. The spindle assembly by the drum, main shaft bearing, bearing, oil seal, end cover, etc.

　　6. The base

　　On both sides of the base is discharging mouth, equipped with wear-resistant liner (exchange), and eddy current crushing cavity, spindle assembly, the motor and transmission are installed on the base of double motor installed on the base with the longitudinal ends, the base fixed on the rack with soft connection methods.

　　7. Drive

　　With double motor drive belt drive structure, double motor drive on both sides of two electric motors are installed in the spindle assembly, the motor pulley with a belt connected to the spindle belt, make the force balance on both sides of the spindle, and does not produce additional torque.

　　8. Lubrication system

　　The equipment adopts the way of thin oil lubrication, have for lubrication oil pump station, using the Great Wall brand in 325 load gear oil for lubrication, lubrication part of the upper and lower bearing two spindle assemblies.
