The depth h2, i.e. h1 > 2*h2 of the mill groove of the depth h1 > 2 times lower millstone of groove.
Up big and down small is because of the fixed upper millstone rotation of are as follows: lower millstone, and slurry more in mill groove drives when upper millstone rotates
Few slurry elapses from inside to outside in lower millstone mill groove, and slurry is avoided to block.
Further, upper interior mill groove is equipped between the most inner side annular groove of upper millstone and the end face of feed opening；Lower millstone
The region of mill groove is equipped with lower interior mill groove in correspondence, and upper interior mill groove and lower interior mill groove angle are arranged.
Graphite slurry can be led in nearest annular groove by upper Nei Mogou, lower interior mill groove, then to external diffusion.
Further, outer mill groove is connected on the outside of the outermost annular groove of upper millstone；The corresponding outer mill of lower millstone
The region of groove is equipped with lower outer mill groove, it is preferable that upper outer mill groove and lower outer mill groove angle are arranged.Outside lower outer mill groove
End is equipped with blanking through slot in communication.
Graphite slurry is ground in mill, at the same the centrifugal force and frictional force the effects of under, graphite powder eventually enters
The lower outer mill groove of discharge tray.After blanking through slot is arranged, graphite slurry is fallen eventually by blanking through slot, is then collected.It keeps away
Exempt from out mill to collect.
Further, the driving mechanism includes transmission shaft, and one end of transmission shaft is connect with upper millstone, transmission shaft it is another
End is connected with driving device.
In practical applications, transmission shaft can be connect by spline with upper millstone, naturally it is also possible to by mandrel connector with it is upper
Mill connection, driving device can be motor, and motor can directly drive transmission shaft rotation, can also be driven by transmission mechanism
Transmission shaft rotation.
Further, the middle part of the upper millstone is equipped with mounting hole, and the middle part of mounting hole is equipped with fixed cylinder, the side of fixed cylinder
Face is connected by the side of multiple spokes and mounting hole, and the gap between adjacent spoke is the feed opening, fixed cylinder with it is described
Driving mechanism connection.
