Connect abrasive disk, realize during the grinding process adjust abrasive disk between grinding block at a distance from.
Working principle of the present invention is as follows:
(1) after pouring into powder in funnel, material is largely fallen on the broken cylinder of extruded layer by gravity and is formed with the broken disk of layer
Cavity in.
(2) extruded layer crushing device is made of the broken cylinder of extruded layer and the broken disk of layer, and the broken disk of layer is connected by material leakage pipe by key I
It connects and is fixed on main shaft, when material enters in extruded layer crushing device cavity, main shaft rotation drives the broken disc spins of layer, and material is by layer
Broken disk drives rotation, material under the cavity portion when it is broken by panel surface and cylinder inner surface bumps type groove extrusion and collision, in sky
The material in the middle part of chamber and top forms that the nearly material bed rotation speed of disk is big when rotated and the material bed rotation speed of remote disk is small shows
As, form material bed relative motion, it is material bed between mutual extrusion, collision, friction it is broken.Broken small particle material particles are logical
The gap crossed between material particles, which moves downward, gradually to be moved to cavity lower part and is crushed again, until grain diameter is less than cavity
Diameter at lower part outlet is fallen among grinding device.
(3) grinding device is equipped with three groups of grinders being made of abrasive disk and grinding block by grinding cylinder and inner barrel
Structure, grinding cylinder are arranged two and install for half cylinder face of similar shape, are arranged three with shape aperture in cylinder middle and lower part, to
Across the convex block of grinding plate edge, and in tapping, screw thread is set；The angled different pitch on abrasive disk and grinding block,
As the carry out particle of grinding is sheared, attrition crushing is at the smaller particle of partial size, ground as particle is fractured into more little particle
Mill apparatus gap is also smaller, until grain diameter is less than the gap between abrasive disk and grinding block, into next grinding mechanism,
The convex block bottom of grinding plate edge is provided with screw thread corresponding on cylinder, between finely tuning between abrasive disk and grinding block
Gap, when abrasive disk passes through screw thread rotation, abrasive disk adjusts the gap between grinding block axially movable, and material enters grinding
When mechanism, by adjusting the gap size between grinding block and abrasive disk, material particles are ground.
(4) material being crushed after process of lapping progress naturally falls in discharging device, the discharge barrel in discharging device
There is coniform disk that material self gravitation effect is made to pass through four outlet outflows in body.
The device course of work provided by the invention is as follows: blocky or different partial size granulate mixture material by bell mouth into
Material, material accumulation is in extruded layer crushing device cavity, and material rotates with when layer broken disc spins, since material is in cavity inside shape
At material bed movement velocity difference make material occur to squeeze between layers, collision, friction it is broken, realize material by for the first time
It is broken, it is fallen into grinding device due to material self gravity along extruded layer crushing device cavity lower part tapping later, abrasive disk
Different with the disk of grinding block cooperation side angle degree, material enters from larger gap, as the carry out particle of grinding is sheared, squeezes
It crushes and is broken into the smaller particle of partial size, flowed out from small―gap suture, as particle is fractured into more little particle grinding device gap
It is smaller, until grain diameter is less than the gap between abrasive disk and grinding block, the centrifugation that particle is generated by self gravity and rotation
Power is fallen from grinding block edge along and into next grinding mechanism, and material is crushed for the second time；Material is crushed by second
Partial size is more unified afterwards, suitably reduces the distance between second level grinding mechanism i.e. the second abrasive disk and the second grinding block at this time, falls
The material to get off enters the gap of second level grinding mechanism, by diminishing cooperation on abrasive disk and grinding block, by grinding
It grinds and screens smaller particles to fall from grinding block edge, material is crushed for the third time；Suitably reduce tertiary grinding again
The gap of mechanism is regrind by third abrasive disk, and material is crushed by the 4th time, and the powder by grinding is by discharging unit
Discharge port is fitted into recyclable device.
