Discharge end device of high-energy mill

Abstract

The invention relates to the field of mills, and discloses a discharge end device of a high-energy mill. The device comprises a discharge end cover connected with a mill cylinder, the discharge end cover is connected with the mill cylinder through an end cover flange, and the discharge end cover is provided with a wet discharge module and / or a dry discharge module. The discharging end device of the high-energy mill can be used for a wet grinding mode and a dry grinding mode, the discharging ore grinding fineness is adjusted by adjusting the height of an overflow adjusting pipe during wet grinding, and meanwhile the discharging end device has the functions of discharging ore grinding materials in a first release hole and discharging steel ball media and steel forging media; during dry grinding, materials are released through a dry discharge port, and ore grinding materials or steel balls and steel forging media are discharged through a second release hole; and the device can be suitablefor a high-energy mill with the characteristics of large size, high ball loading rate, low energy consumption, universality for dry grinding and wet grinding, and has the advantages of material blockage prevention, ore grinding fineness adjustment and medium discharge and the like.

Description

technical field

[0001] The invention relates to the field of mills, in particular to a high-energy mill discharge end device. Background technique

[0002] The discharge and discharge end of known ball mills or other types of mills is a sealed end cover with a discharge hole in the center, which does not have the functions of medium discharge and material fineness control.

[0003] For example, the national patent document CN201342360 discloses a "ball mill discharge end cover". The utility model discloses a ball mill discharge end cover. The hollow journal (4) is fixedly connected to the end cover plate (2). A hole (3) is provided, the upper end of the end cover disk is concaved to form an inner cone surface, and a step (1) is provided at the mouth of the end cover disk. This utility model cannot be applied to high-energy mills with the characteristics of large-scale, high ball loading rate, low energy consumption, dry grinding and wet grinding, and does not have functions...
