detailed description

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

See Figure 1 and Figure 2, the structural diagram of the self-lining impact crusher, the cross-sectional structural diagram of the self-lining impact crusher crushing chamber, the self-lining impact crusher, including the feeding port 1, the crushing chamber 2, the ore automatic Lining layer 3, rotor 4, discharge port 5, main shaft 6, spiral bevel gear transmission 7, power transmission shaft 8, pulley 9, base 10, casing 11, lining plate 12, rotor cavity 13 and rotor discharge 14, the top of the crushing chamber 2 is provided with a feeding port 1, the interior of the crushing chamber 2 is provided with a rotor 4, the inner side of the crushing chamber 2 has an ore self-lining layer 3, and the lower part of the rotor 4 is provided with a discharge port 5. The rotor 4 is axially connected to the main shaft 6, and the main shaft 6 is connected to the power transmission shaft 8 through a spiral bevel gear transmission 7. The end of the power transmission shaft 8 is provided with a pulley 9, and the pulley 9 passes through a belt It is connected with the motor, the motor is connected with the power supply, the lower part of the discharge port 5 is bolted to the organic casing 11, the lower part of the casing 11 is bolted to the base 10, the main shaft 6 is located inside the casing 11, and the main shaft 6 is perpendicular to the power transmission shaft 8, and the linear speed at which the rotor 4 rotates is 120-150 m/s. The lining plate 12 is welded or riveted on the inner wall of the crushing chamber 2 , the rotor 4 is circular, and a rotor discharge port 14 is arranged on the edge of the rotor 4 , and a rotor cavity 13 is opened in the rotor 4 .

When in use, connect the motor to the power supply, start the motor, and the rotation of the motor drives the belt pulley 9 to rotate, and the rotation of the belt pulley 9 drives the power transmission shaft 8 to rotate, thereby driving the main shaft 6 to rotate, and the rotation of the main shaft 6 drives the rotor 4 to rotate, and the raw ore is fed from the feed port 1 Feed into the crushing cavity 2, when the ore falls on the rotor 4, it enters the rotor inner cavity 13, and the ore in the rotor inner cavity 13 rubs against the ore fed by the feeding port 1 to perform the first crushing After the first crushing, the ore is thrown out by the centrifugal force from the rotor outlet 14 and flies to the inner wall of the crushing chamber 2. The liner 12 welded or riveted on the inner wall of the crushing chamber 2 can effectively protect the crushing chamber 2, and the ore and The inner wall of the crushing chamber 2 is effectively impacted and crushed for the second crushing, and at the same time an ore self-lining layer 3 is formed on the inner wall of the crushing chamber 2. When the ore is on the rotor 4 again and is thrown out by centrifugal force, the ore and ore Collision occurs from the lining layer 3 for the second crushing, so that the ore is crushed, and the crushed ore is discharged through the discharge port 5.

In the utility model, the rotor 4 throws out the ore at a high-speed linear speed, and the crushing process includes impact, impact, friction and shearing, and has the functions of crushing and grinding at the same time, so it has the characteristics of integrating crushing and grinding. It has high crushing efficiency and strong crushing process, which can replace the impact crushing in industrial production, the fine crushing of cone crusher and the coarse grinding of self-grinding machine, so that the process flow can be simplified, and the investment and production costs can be reduced.

In the utility model, the rotor 4 throws the ore at a high-speed linear speed and hits the self-lining ore for crushing.
