A new type of energy-saving ball mill

Abstract

The invention discloses a novel energy-saving ball mill. The novel energy-saving ball mill consists of a first hydrostatic bearing, a second hydrostatic bearing, a rotator, hydrostatic bearing sealing covers, a local dust collector, a small gear and a transmission system; the shaft journals of hollow shafts at the two ends of the rotator are respectively placed on the first hydrostatic bearing and the second hydrostatic bearing and are covered by the two hydrostatic bearing sealing covers respectively; a large gear which is engaged with the small gear is arranged on the periphery of the rotator; high-pressure oil forms a lubricating oil film among the first hydrostatic bearing, the second hydrostatic bearing and the shaft journals of the hollow shafts of the rotator, so that the rotator can float, the completeness of the lubricating oil film can be guaranteed and the complete liquid lubrication can be realized; the bearing capacity of the bearings is large; when the rotator generates the small bending elastic deformation, bearing bodies of the first hydrostatic bearing and the second hydrostatic bearing rotate at a small angle relatively around respective first pin shafts, so that the thickness of the oil film is not changed basically; the grinding effect between a grinding medium and a mineral aggregate and among the mineral aggregates can be enhanced because of a corrugated liner plate in the rotator; and the sealing covers and the local dust collector can effectively prevent dust particles in the working environment of the ball mill from entering the working space of the hydrostatic bearings.

Description

technical field [0001] The invention relates to a ball mill, in particular to a novel energy-saving ball mill. Background technique [0002] The specifications of ball mills continue to increase, which puts forward higher requirements for their productivity and energy consumption. The existing large-scale ball mills have to improve productivity, low operating reliability, frequent failures, high operating energy consumption and use and maintenance costs. Contents of the invention [0003] The object of the present invention is to provide a novel energy-saving ball mill. [0004] The present invention is composed of a first static pressure bearing, a second static pressure bearing, a rotary body, two static pressure bearing sealing covers, a first partial dust collector, a second partial dust collector, a pinion and a transmission system; The two journals of the hollow shaft are respectively placed on the first hydrostatic bearing and the second hydrostatic bearing, and ar...
