In the scheme, the problem that the low-nickel matte is easy to grind due to different sizes of low-nickel matte particles when a ball mill is used for grinding the low-nickel matte is solved, the mounting frame 1 is detachably connected with the base 102 through bolts, a bearing can be installed between the supporting seat 2 and the adjacent hollow shaft 3, resistance when the hollow shaft 3 rotates is reduced, the hollow shaft 3 is detachably connected with the cylinder 4 through bolts, a power system consists of a motor, a speed reducer, a gear and a toothed ring, the toothed ring is installed on the right side of the cylinder 4 through bolts, the gear is driven to rotate through the motor, the gear is meshed with the toothed ring and drives the cylinder 4 to rotate (the cylinder 4 rotates clockwise in the right-left direction in the process of grinding the low-nickel matte through rotation of the cylinder 4 and driving grinding balls in the cylinder), and qualified low-nickel matte particles with the particle size are discharged out of the cylinder 4 through the screen 6, so that the situation of the low-nickel matte is prevented from being excessively ground.
The specific working flow of the scheme is that low nickel matte is put into a cylinder 4 through two charging holes 301, then a motor is started, an output shaft of the motor drives an input shaft of a speed reducer to rotate, an output shaft of the speed reducer drives a gear to rotate, the gear drives the cylinder 4 to rotate through a toothed ring, the cylinder 4 drives grinding balls in the speed reducer to move, and the grinding balls move along with throwing movement and pouring movement of the grinding balls (when the rotating speed of the cylinder 4 is small, the grinding balls rise to a certain height along with the inner wall of the cylinder 4 under the action of centrifugal force and friction force between the grinding balls and the cylinder 4, then the grinding balls lose contact with the inner wall of the cylinder 4 and roll down along the grinding balls and low nickel matte particles which are piled up to form pouring movement, and when the rotating speed of the cylinder 4 is proper, the grinding balls rise to a certain height along with the cylinder 4, then the grinding balls do parabolic movement and impact and crush the low nickel matte piled up on the lower side of the cylinder 4, namely throwing movement; because the sizes of the grinding balls in the cylinder 4 are different, a part of the grinding balls are in a falling motion in the rotation process of the cylinder 4, and the other part of the grinding balls are in a throwing motion), the low-nickel matte in the cylinder 4 is impacted and ground, so that the particle size of the low-nickel matte is gradually reduced, the low-nickel matte moves along with the cylinder 4 along with the rotation of the cylinder 4, meanwhile, the low-nickel matte and the cylinder 4 relatively slide, when the low-nickel matte particles move to the upper side of the screen 6, the low-nickel matte particles with qualified particle size pass through the screen 6 and the adjacent discharge groove 601 and enter between the discharge shell 5 and the cylinder 4, and then the low-nickel matte particles move along the discharge shell 5 and finally enter the magnetic separator 101 through the discharge hole 501 to carry out magnetic separation on the low-nickel matte, so that the low-nickel matte is prevented from being overground, and the particle size qualification rate of the low-nickel matte finished product after ore grinding is improved.

In the scheme, the screen 6 is protected, grinding balls are prevented from directly colliding with the screen 6, the service life of the screen 6 is prolonged, the guard plate 7, the split blocks 8 and the reinforcing blocks 9 are made of high manganese steel or high chromium cast iron, the guard plate 7, the split blocks 8 and the reinforcing blocks 9 are made of high impact resistance and wear resistance, the guard plate 7 is approximately U-shaped, the left part and the right part of the guard plate 7 are fixedly connected with the inner side of the cylinder 4, the gap between the middle part of the guard plate 7 and the adjacent screen 6 is larger than the diameter of a filtering hole on the screen 6, low nickel matte particles with the particle size close to the acceptable particle size can enter between the screen 6 and the guard plate 7 and slide along the screen 6, the low nickel matte particles with the particle size acceptable particle size are discharged through the screen 6, the gap between the middle part of the guard plate 7 and the adjacent screen 6 is equal to the gap between the two split blocks 8, and the low nickel matte particles are prevented from being clamped between the screen 6 and the guard plate 7, namely the low nickel matte particles can be pre-screened by utilizing the gap between the two split blocks 8.
When the cylinder body 4 rotates, the grinding balls in the cylinder body 4 collide with the guard plate 7, the flow dividing block 8 and the reinforcing block 9, so that the grinding balls are prevented from directly colliding with the screen 6 to damage the screen 6, meanwhile, the guard plate 7, the flow dividing block 8 and the reinforcing block 9 are used for providing rigid support for the grinding balls to ensure the collision effect of the grinding balls and the low-nickel matte, and meanwhile, the guard plate 7, the flow dividing block 8 and the reinforcing block 9 are used for enabling the inner wall of the cylinder body 4 to form bulges, so that the grinding balls are driven to move through the cylinder body 4.
Referring to fig. 6, the angle between the diverter block 8 and the side of the adjacent guard plate 7 is between 30 ° and 45 °.
In the above scheme, the area of collision dead points is reduced, and the included angle of the split blocks 8 is 30 degrees, so that on one hand, the grinding balls can impact and grind the low-nickel matte particles near the split blocks 8, the problem that the low-nickel matte particles at the corners of the split blocks 8, which are fixedly connected with the cylinder 4, cannot be impacted by the grinding balls is avoided, and on the other hand, when the low-nickel matte particles are clamped in the gaps of two adjacent split blocks 8, the grinding balls are easy to collide with the low-nickel matte particles in the gaps of the two adjacent split blocks 8 along with the throwing movement of the grinding balls in the cylinder 4, so that the clamped low-nickel matte particles are broken, and meanwhile, the split blocks 8 and the guard plate 7 form bulges on the inner wall of the cylinder 4, so that the auxiliary cylinder 4 drives the grinding balls to move.
Referring to fig. 6, the sum of the width of the diverter blocks 8 and the gap between two adjacent diverter blocks 8 is less than the diameter of the smallest grinding ball.
In the above-mentioned scheme, in order to prevent the grinding balls from shielding the continuous gap (i.e. the gap between two adjacent split blocks 8), when the cylinder 4 rotates, the cylinder 4 drives the grinding balls to move by the assistance of the protrusions formed by the split blocks 8 and the guard plate 7, the grinding balls are easy to stay in the gap between two adjacent split blocks 8, in order to avoid the grinding balls from shielding the continuous row of gaps, two grinding balls cannot be located in two continuous gaps (i.e. the gap formed by two adjacent split blocks 8) at the same time, and in the case that the grinding balls just shield the continuous gaps, i.e. the two grinding balls staying in two adjacent gaps are in contact with each other, at this time, the sum of the diameters of the two grinding balls is equal to the sum of the widths of the two split blocks 8 and the widths of the two gaps, i.e. in order to prevent the grinding balls from shielding the continuous gaps, the diameter of the grinding balls is required to be larger than the sum of the width of one split block 8 and the width of one gap.
Referring to fig. 5 and 6, the device further comprises a plurality of supporting blocks 10 fixedly connected to one sides of the adjacent guard plates 7 far away from the central axis of the cylinder 4, wherein the supporting blocks 10 are fixedly connected with the adjacent reinforcing blocks 9 and the adjacent dividing blocks 8.

Referring to fig. 3, 4, 7 and 9, the device further comprises a plurality of extrusion plates 11, a plurality of elastic sheets 12 and a guide piece 13, wherein the extrusion plates 11 are all in limit sliding connection in the cylinder 4, the number of the elastic sheets 12 is equal to that of the extrusion plates 11, the elastic sheets are fixedly connected to one sides, far away from the central axis of the cylinder 4, of the adjacent extrusion plates 11 respectively, the guide piece 13 is fixedly connected in the discharge shell 5, and the elastic sheets 12 are in extrusion fit with the guide piece 13.
In the above scheme, the aim is to improve the moving efficiency of the grinding balls when the cylinder 4 rotates, because the grinding balls in the ball mill are different in size, when the ball mill is in running, one part of the grinding balls are in a falling motion, and the other part of the grinding balls are in a throwing motion, if the rotating speed of the ball mill is simply increased, one part of the grinding balls are in centrifugal motion (i.e. are always attached to the inner wall of the ball mill), so that the proportion of the grinding balls in the throwing motion cannot be increased by simply increasing the rotating speed of the ball mill, the guide piece 13 is positioned at the front upper part of the cylinder 4, the limit sliding of the extrusion plate 11 and the cylinder 4 can be realized through a sliding groove and a limit bulge (see fig. 9), meanwhile, the sliding groove of the extrusion plate 11 is positioned at the back side in the circumferential rotating direction, so that the probability that low nickel matte particles are clamped in the sliding groove of the extrusion plate 11 is reduced, the normal running of the extrusion plate 11 is facilitated, and when the cylinder 4 rotates, the cylinder 4 drives the extrusion plate 11 to rotate in the circumferential direction, the extrusion plate 11 drives the adjacent elastic piece 12 to gradually contact with the guide piece 13 and move along the guide piece 13, the guide piece 13 extrudes the adjacent elastic piece 12, and the elastic piece 12 drives the adjacent extrusion plate 11 to move, and the adjacent nickel ball 4 to move into the inner wall, thereby improving the friction and the grinding ball grinding mill, and the grinding polishing efficiency.
Referring to fig. 7, all the squeeze plates 11 are staggered with all the discharge grooves 601, and the distance between the squeeze plates 11 and the adjacent split blocks 8 is smaller than the distance between the squeeze plates 11 and the adjacent reinforcing blocks 9.
In the scheme, the extrusion plate 11 is used for shielding the gap between the two adjacent flow dividing blocks 8, low-nickel matte particles with proper particle sizes are prevented from continuously entering the gap between the two adjacent flow dividing blocks 8, the barrel 4 is assisted by the extrusion plate 11 to drive the low-nickel matte particles to move, the low-nickel matte particles are thrown down, the uniformity of distribution of the low-nickel matte particles in the barrel 4 is improved, and the probability of collision between the low-nickel matte particles and grinding balls is further increased.
Referring to fig. 7 and 8, the distance between the pressing plate 11 away from the guide 13 and the central axis of the cylinder 4 is greater than the radius of the cylinder 4, and the elastic sheet 12 is provided with two bent portions 121, and the bent portions 121 are in contact with the cylinder 4.
In the above scheme, the purpose is to form a pit on the inner wall of the cylinder 4 by using the extrusion plate 11, change the motion track of the grinding ball, make the motion track of the grinding ball more complex, change the motion direction and speed of the grinding ball by using the collision of the grinding ball and the groove, further increase the impact collision times and strength of the grinding ball and the low nickel matte, improve the ore grinding speed of the low nickel matte, and simultaneously make the contact point of the bending part 121 and the cylinder 4 arc, avoid scratching the outer wall of the cylinder 4 when the corners of the elastic sheet 12 move, and also improve the service life of the elastic sheet 12 and the cylinder 4.
In the process of rotating the cylinder 4, under the action of the rotating speed of the cylinder 4 and the friction force of the cylinder 4 on the grinding balls and the low nickel matte particles, the low nickel matte particles and the grinding balls slide relatively when moving at the middle lower side of the cylinder 4, so that the low nickel matte particles can pass through the gap between two adjacent flow dividing blocks 8, enter between the screen 6 and the adjacent guard plate 7, slide along the side surface of the screen 6, pass through the screen 6 when the low nickel matte particles slide along the screen 6, enter the adjacent discharge groove 601, then after the extrusion plate 11 rotates to the middle upper side of the cylinder 4 in the circumferential direction, the elastic piece 12 is in contact with the guide piece 13, the extrusion plate 11 is extruded to protrude out of the cylinder 4 by the guide piece 13, and at the moment, the extrusion plate 11 blocks the low nickel matte particles and the grinding balls from sliding relative to the cylinder 4, thus the cylinder 4 is convenient to drive the low nickel matte particles and the grinding balls to move, throwing movement is easy to form, and the crushing effect of the low nickel matte particles is improved.
