Pure-hydrostatic tube mill

Abstract

The invention discloses a pure-hydrostatic tube mill comprising a feeding device, a feeding end supporting system, a rotary part, a discharging end supporting system, a discharging device and a lubrication and control station. The feeding end supporting system (3) of the rotary part (4) is provided with a flat-seat-type pure-hydrostatic slipper moving bearing structure; the discharging end supporting system (5) of the rotary part is provided with a flat-seat-type pure-hydrostatic slipper axial anti-thrust bearing structure; and the flat-seat-type pure-hydrostatic slipper moving bearing structure and the flat-seat-type pure-hydrostatic slipper axial anti-thrust bearing structure lubricate a pure-hydrostatic slipper bearing through the high-pressure oil of the lubrication and control station so as to form a thicker oil film between a cylinder sliding ring (7) and a slipper bearing pillow (8) and realize full-liquid lubrication. The invention can solve the problem of overhigh temperature of the slipper bearing in a common tube mill and realize the conversion of the support of a large-size cement mill by a dynamic-pressure bearing or a dynamic and static pressure bearing to the support by a pure-hydrostatic slipper bearing so that the cement mill becomes high-efficiency grinding equipment.

Description

technical field [0001] The invention relates to the technical field of cement equipment, in particular to a pure static pressure tube mill suitable for cement production. Background technique [0002] At present, in the cement production process, due to factors such as cement production process, production area, ambient temperature, and ventilation conditions, the temperature of the cement after grinding will reach above 100°C. Under such high temperature conditions, the traditional sliding shoe cement mill commonly used in the cement industry at present, because the sliding shoe bearing is directly supported on the cylinder of the mill, the high temperature of the material is directly transmitted from the cylinder to the sliding shoe bearing, so the sliding shoe cement The bearing temperature of the mill is generally high. The sliding shoe bearings have short service life, frequent tile burning, low operating efficiency, high wear power consumption, and weak carrying capac...
