Automatic companion stone embedding and lining autogenous grinder

Abstract

The invention relates to an automatic companion stone embedding and lining autogenous grinder which is formed by a motor, a speed reducer part, a transmission part, a support foundation part and a shell part. The shell part is formed by at least one section of shell unit. The automatic companion stone embedding and lining autogenous grinder is characterized in that one end of the shell unit is a feed end; the other end of the shell unit is a discharge end; a shell liner is arranged on the inner wall of the shell unit and is formed by grid sections uniformly distributed on the circumference at intervals; a grid section groove is formed between each two adjacent grid sections; a cross section of each grid section is characterized in that the end in the direction toward the center of the shell unit is wide, and the end in the direction toward the inner wall of the shell unit is narrow; a cross section of each grid section groove is characterized in that the end in the direction toward the center of the shell unit is narrow, and the end in the direction toward the inner wall of the shell unit is wide; the horizontal surface in the length direction of each grid section is narrow at the feed end and wide at the discharge end; and the horizontal surface in the length direction of each grid section groove is wide at the feed end and narrow at the discharge end. The automatic companion stone embedding and lining autogenous grinder has the advantages of light liner weight, capabilities on automatically selecting applicable mineral particles to be inlaid into a liner groove so as to substitute lining and assist grinding, and capabilities on automatically locking stones and retreating and supplementing stones.

Description

technical field [0001] The invention relates to an automatic interlining self-grinding machine with accompanying stones, which belongs to the field of mineral processing equipment. Background technique [0002] The inner wall of the traditional autogenous mill barrel is equipped with a full-cover metal liner or a full-cover ore liner. The ore is directly fed into the autogenous mill, and the ore itself is used as the medium to achieve crushing through mutual impact and grinding. In order to improve the processing capacity, a small amount of rods and balls are sometimes added to the autogenous mill, so it is often called a semi-autogenous mill. Therefore, the self-grinding machine is a kind of grinding equipment with two functions of medium and fine crushing and coarse grinding. It is widely used in the grinding of artificial stone sand, mineral processing plants, chemical plants, electric power and other departments. [0003] The main structure of the traditional autogenou...

AI Technical Summary

Problems solved by technology

The number of lining boards is large, and hundreds of holes need to be drilled on the cylinder shell, which seriously affects the strength of the cylinder. Thick metal lining boards or stone lining boards are vulnerable parts, and the manufacturing cost is high. The surface is smooth and the grinding performance is high. Poor, low production capacity, heavy weight, high energy consumption, large consumables, high replacement and maintenance costs

The particle size of the feeding and discharging ore in the center of the shaft hole is limited, and the larger material cannot be fed into the cylinder. The material that has entered the cylinder is rotated and accumulated beyond the center radius due to the central discharge, and the ore is thrown from the side of the cylinder. Small, the potential energy is weakened and the impact force is insufficient, which directly affects the grinding effect

Abandoning the central hole discharge and changing to a single bottom discharge of the cylinder, its structure also has obvious defects such as inability to separate diameters, classify and delay grinding; it is impossible to discharge small particles at the tail end or tail of the cylinder immediately, and it is impossible to discharge the larger particles. Large particles are discharged after continuous finishing; it is impossible to choose suitable granular minerals in the input ore to insert grooves to replace the grinding aid, and it is often replenished and renewed; it is impossible to automatically lock and restore stones, and it is impossible to use attapulgite as teeth , act as a gripper, act as a wear-resistant medium, and improve the efficiency of grinding, descaling and rust removal; it cannot reduce the cost of manufacturing and replacing the lining plate, and cannot reduce the weight of the cylinder and the large power required by the motor.

Individual water injection process is adopted, but the load-bearing effect of the discharge screen is poor, it is not wear-resistant, the diameter is small, and the performance is low
