On the basis of the technical scheme, the screening roller comprises roller sleeves, a main shaft, bearings and bearing seats, the roller sleeves are fixed on the main shaft through flat keys, two ends of the main shaft are installed with the bearings in the bearing seats, the positions of the roller sleeves on the main shaft are staggered and gaps are reserved, and the size of the gaps can be set according to particle requirements.
On the basis of the technical scheme, the counterattack grate A and the counterattack grate B are provided with feed openings, and the size of the feed openings can be set according to the particle requirements.
Compared with the prior art, the utility model has the following advantages: the screening rollers are not provided with power transmission, the main shaft is driven to rotate by the falling gravity of ore, due to the fact that a proper gap exists between the roller sleeves, the material smaller than the gap between the roller sleeves is screened in advance and does not enter the grate to be crushed any more in the falling process of the ore along the roller sleeves, and the counterattack grate A and the counterattack grate B are provided with the discharge ports, so that the proper material is discharged in advance and is not crushed repeatedly. The crushing efficiency of the equipment is greatly improved, the useless work of part of rotor crushing is reduced, the unsmooth crushing and discharging condition is improved, the service life of the hammer head is greatly prolonged, and the yield of the equipment is greatly improved.

Detailed Description
The utility model is explained in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1-5, a heavy hammer crusher comprises an upper shell 1, a counterattack lining plate 2, a counterattack grate a3, a grate frame 4, a lower shell 5, a grate 6, a hammer 7, a hammer shaft 8, a rotor 9, a counterattack grate B10, a screening roller 11 and a material receiving chute 12, and is characterized in that: go up casing 1 and lower casing 5 and pass through the bolt installation, casing 5 is fixed through rag bolt and ground down, it has a plurality of counterattack welts 2 to go up 1 inboard upper surface of casing through the bolt fastening, it has counterattack grate A3 through the bolt fastening on the vertical face in left side in the casing 1 to go up, comb frame 4 is fixed in casing 5 down for semicircular structure, 4 medial surfaces of comb frame are fixed with a plurality of grates 6 through the slider, and are a plurality of the tup 7 is installed in the circumference outside of rotor 9 through hammer spindle 8, rotor 9 and comb frame 4 concentric installation, it has counterattack grate B10 through the bolt fastening on the vertical face in right side in the casing 1 to go up, the screening roller 11 of slope is installed on the right side in the casing 1, screening roller 11 is greater than 30 degrees with the horizontal plane contained angle, the swift current of screening roller 11 right-hand member connects the material son 12 and is fixed with last casing 1.
