As shown in Figure 1: this broken grinding machine is by feed hopper, support, discharge bucket, wherein be provided with breaker and milling device in the support, they by a main shaft be connected as a single entity up and down form.Wherein feed hopper 16 is located on the support 1 and covers, and discharge bucket 15 is fixed in the bottom of support by bolt and nut, and support 1 joins by bearing axle sleeve and main shaft 2.Breaker places the top in the support, and milling device places the lower part in the support.Wherein breaker mainly is made up of tup seat 4, tup top board 5 and dental lamina 6 that the lower platen 18 of tup 3, protective shaft sleeve 17 and tup is constituted.Shown in Fig. 2,3: wherein top board and tup seat are contained on the main shaft, the tup seat is fixed on the main shaft by key 19, between the outer toroid of tup seat lower platen and protective shaft sleeve, be provided with rib, there are 2～4 to adjust the also draw-in groove of fixed hammer between the rib, top board 5 is the equilateral triangle face, be provided with corresponding draw-in groove on itself and the corresponding face of rib, the upper and lower side of tup 3 is processed with the protrusion contiguous block respectively, with its device on top board and tup seat in the set upper and lower draw-in groove.Shown in Fig. 8,9: also can be at the tup seat rib, protective shaft sleeve and and top board between welding one upright plate 27, on upright plate, be processed with long slot bore 26, also be provided with the zigzag draw-in groove on the interior plate face of upright plate, be assemblied in the tup on the tup seat, be processed with on it with upright plate on two sawtooth being meshed of sawtooth draw-in groove, and and the connecting hole that fixes of tup seat, they by the bolt connection for together.End device has a gusset seat 7 in support, and it partly is made of a cylindrical portions may and a large circle that has rib, and it is used as parts such as device dental lamina, abrasive stick, and wherein dental lamina 6 is embedded in the inboard of gusset seat cylinder, and evenly distributes every 36 degree.Referring to Fig. 4: milling device is that gusset seat 7 and pallet 12 are formed by last abrasive stick 8, abrasive stick 9, upward round abrasive stick 10, round abrasive stick 11 down down.Last abrasive stick is 3: 2 with the ratio of following abrasive stick number, wherein goes up on the rib that abrasive stick is separately fixed at the gusset seat, and following abrasive stick is fixed on the rib set on the pallet, and an end of upper and lower abrasive stick is the inclined-plane, and it has two effects: 1, to reduce the frontal drag of air.2, generation wind-force up and down blows out the material that crushes from the slit of last lower grid plate.Pallet is contained on the main shaft and by key and limits.Top grating 13 is housed on the gusset seat, lower grid plate 14 is housed above the pallet, upward round abrasive stick 10 is fixed on the large circle of gusset seat 7 by bolt and nut; Round down abrasive stick 11 is fixed on the periphery of pallet, justifies an adjacent week of abrasive stick having formed gap, an inclined-plane up and down, and this gap is 3mm.As shown in Figure 5: the bottom of above-mentioned gusset seat 7, pallet 12, support 1 all is similar to shape shown in Figure 5, their centers are provided with the centre bore with spindle mounted, an outer shroud is arranged, between centre bore and the outer shroud muscle is arranged, rib for leaking the space of material, is provided with draw-in groove between the rib on the pallet each other.See Fig. 1, the upper end of gusset seat 7 is contained on the loam cake 25 of support by six bolt screws, wherein three bolts 23 and other three screws 24 direction when assembling is opposite, bolt 23 is to cover for gusset seat 7 is fastened on the support, and screw 24 is to be used to impel the gusset seat to be separated from the support loam cake and adjusting downwards.Shown in Fig. 6,7: the upper end of discharge bucket 15 is that annular is collected mouth, and referring to Fig. 1, a side of its ring side face and upper end annular are collected mouthful structure in angle of 45 degrees.This discharge bucket sealing is tight, and discharging smoothly.Its major advantage is a good airproof performance, isolates fully with motor pulley, makes belt pulley not contact dust with belt and is protected.

The course of work: when motor (motor is rotated counterclockwise) drives belt pulley 20 rotations, main shaft 2 is in rotation, all rotating with all parts that main shaft extremely is connected, be that top board, tup seat and tup rotate simultaneously, compress by nut 21 on the top board, so can not become flexible, the pallet band down abrasive stick, lower grid plate and down round abrasive stick along with main shaft is also rotating.When material (for example stone 22) is sent into from feed hopper 16, space from top board enters in the breaker then, by the interaction of tup and dental lamina and the interaction of material self, make material in fragmentation, broken material reaches below the 20mm, the space of the material that is broken on the tup seat fallen in the milling device, because action of centrifugal force, material is entered up and down between the abrasive stick, last abrasive stick maintains static, because of following abrasive stick with pallet around main axis rotation, make material mill again and reach below the 3mm, on, the discharging gap of lower grid plate is also designed at 3mm, in addition, on, gap between round down abrasive stick also is 3mm, at this moment reaches 3mm or less than the material particles of 3mm, from last, lower grid plate and last, discharge in the gap of round abrasive stick down.And the effect of upper and lower round abrasive stick mainly is in order to seal a week of upper and lower abrasive stick, prevents that from then on big material from missing.Gap on the screen can be designed processing as required.The small particles material that is discharged from enters in the discharge bucket from the space of support bottom.

All main wear-out parts in this design are all easily changed, and no matter are shown in Fig. 2,3 or shown in Fig. 8,9, and one pair of tup can carry out 3～5 times to be adjusted, till it is used up (unrenewable).Last abrasive stick is 2: 1 with following abrasive stick, if last abrasive stick is 12, and abrasive stick is 8 down, and machine is when work in other words, and abrasive stick is in afterburning work done up and down to remain four pairs, and this design has promptly guaranteed operating efficiency, saves the energy again.When abrasive stick wearing and tearing up and down and spacing when strengthening, but loose bolts 23 by artificial adjustment screw 24, moves down gusset seat 7, also moves down and go up bar abrasive stick 8 thereupon, guarantees the original spacing of abrasive stick up and down.
