Description

Technical Field

[0001] The utility model belongs to the technical field of mining production and relates to an ore-sliding device for a gyratory crusher. Background Art

[0002] As the main component of the ore conveying system in underground mines, the chute system mainly transfers the ore through the transfer chute and puts the ore into the crusher for coarse crushing using a vibrating ore-feeder. During the operation of the vibrating ore-feeder, the vibrating motor uses high-frequency vibration to make the ore flow at high speed in the ore-feeder and then be crushed in the crusher cavity. When the ore enters the crushing cavity through the discharge port of the vibrating ore-feeder, a certain distance needs to be reserved for the installation height of the equipment due to the installation requirements of the vibrating ore-feeder and the crusher. During the operation, the ore is continuously accumulated to form an inclined surface, causing the ore-feeder to descend slowly and the wear speed of the crusher shaft wall to accelerate. Personnel need to cooperate with the hook machine to clean it twice a month, which seriously affects the normal operation of the entire crushing system. During this period, the main The following problems: (1) When the vibrating ore discharger discharges ore normally, the ore at the discharge port accumulates from bottom to top and falls into the crusher cavity, forming an inclined plane with the crossbeam base plane, so that the ore is blocked below the discharge port, resulting in indirect contact between the discharge port table and the ore, which can easily cause the vibrating ore discharger to overload; (2) There are certain risks when the operators enter the crushing cavity to clean the ore, which brings great difficulty to the crushing ore and cleaning operations, and is time-consuming and labor-intensive; (3) The height difference between the vibrating ore discharger and the crusher cavity reference plane is close to 8~10m. The large height difference causes impact on the crusher cavity, making the crushing cone unbalanced, resulting in an increase in the force area and increasing the wear of the ore on the machine body.
