Universal grinder is a high-speed rotary percussive, depending on the structure and force through a combination of different grinding components, can be composed of a turbine, needle stick type, wing plate, half ring half screen type and ring gear type several crushed equipment.
1.1, the principle
Material from the hopper by the screw conveyor into the crushing chamber, generated by the high-speed rotation of the rotor (such as leaf and needle bar, toothed, etc.) with a fixed stator (e.g. ring gear) between the strong impact force, shear force by friction be crushed so that the material generated by the strong impact force, shear force, friction, the material is pulverized, the powder is discharged through the sieve machine chamber, the particle sizes obtained through the replacement of the different aperture sieve.
1.2, Features
Has its universal grinder:
(1) high-yield, low noise, low energy consumption, simple maintenance, easy installation;
(2) gap between the rotor and the stator precise fit, the smash best results;
(3) good sealing performance, internal labyrinth seal, the door has an O-ring seal, to prevent dust to escape;
(4) Due to the high-speed rotation of the rotor, into a lot of air, and thus self-cooling function, low heat-sensitive material crushing to the applicable requirements;
(5) The system piping connections Quick release structure, can quickly and easily disassembly, cleaning;
(6) can be equipped with a cyclone and dust, no dust in the production process, the dust collection bag micronized effectively trapped gas stream. At the same time, the fine powder dust collection bag interception can effectively recover and reduce the rate of material loss
The universal grinder correct use
1, universal grinder and power unit should be securely installed. Universal grinder fixed long-term job, it should be fixed on a cement foundation; universal grinder is a mobile operation, the unit should be installed in the chassis made with angle iron, and to ensure that the power machine (diesel or electric motor) and Universal crushed The machine pulley groove is rotating in the same plane.
The universal grinder after installation to check ministries fasteners fastening tighten if loose be. At the same time you want to check the belt tightness is appropriate.
Universal grinder before starting the first hand to rotate the rotor, check teeth claw hammer and rotor operation is flexible and reliable, shell or without collision phenomenon, the direction of rotation of the rotor is under the machine arrow direction, the power machine and the universal grinder lubrication.
4, it should not replace the pulley to prevent excessive speed grinding chamber to produce an explosion, or the speed is too low to affect the efficiency of the universal grinder.
Universal grinder starter should idling 2 ~ 3min, no anomalies before feeding. Work to pay attention to a universal grinder functioning, feeding should be uniform to prevent blocking boring car, not to overload of work for a long time. If there is vibration, noise, bearing and body temperature is too high, spray material outward phenomenon should immediately stop check, troubleshooting before they continue to work. |
Is very important to use the correct universal grinder can extend equipment life
