Energy-saving ball mill

Abstract

The invention discloses an energy-saving ball mill which consists of a first hydrostatic bearing, a second hydrostatic bearing, a rotating body, hydrostatic bearing sealing covers, a local dust collector, a pinion and a transmission system, wherein hollow shafts at two ends of the rotating body are respectively arranged on the first hydrostatic bearing and the second hydrostatic bearing and are respectively covered by the two hydrostatic bearing sealing covers; the periphery of the rotating body is provided with a gearwheel meshed with the pinion; high pressure oil forms a lubricating oil film among the first hydrostatic bearing, the second hydrostatic bearing and the shaft neck of the hollow shaft of the rotating body, the rotating body can float, the lubricating oil film can be kept complete, and the liquid lubrication is completely realized; the bearing has high bearing capacity; when the rotating body generates small elastic bending deformation, the bearing bodies of the first hydrostatic bearing and the second hydrostatic bearing relatively rotate by a small angle around first pin shafts respectively, so that the thickness of the oil film is basically invariable along the axial direction; according to the corrugated lining plate in the rotating body, the abrasive action between the abrasive medium and mineral aggregate and between the mineral aggregate is enhanced; and moreover, according to the sealing covers and the local dust collector, the dust particles in the ball mill operating environment can be efficiently prevented from entering the operating space of the hydrostatic bearings.

Description

technical field

[0001] The invention relates to a ball mill, in particular to an 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, the existing large-scale ball mills, the productivity needs to be improved, the operation reliability is low, failures occur frequently, and the operation energy consumption and higher maintenance costs. Contents of the invention

[0003] The object of the present invention is to provide an 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 journals of the hollow shaft are respectively placed on the first hydrostatic...
