Description

Technical Field

[0001] The utility model relates to the technical field of lubrication equipment, in particular to a mainframe lubrication device for an internal reduction pendulum type grinding mill. Background Art

[0002] The pendulum mill, also known as the suspension roller mill or Raymond mill, is a "ring-roller" grinding combined with airflow screening and pneumatic conveying in the form of powder making equipment, which belongs to the disc stationary type disc mill. The pendulum mill is a kind of powder making equipment with strong versatility, and its main features are dry continuous powder making, concentrated particle size distribution, continuously adjustable fineness, and compact structure. The structure of the machine is mainly composed of the main machine, analyzer, fan, finished product cyclone separator, micro powder cyclone separator and air duct. Among them, the main machine is composed of a frame, an air inlet volute, a scraper, a grinding roller, a grinding ring, and a cover. When working, the material to be crushed is added into the machine from the feed hopper on the side of the machine cover. Relying on the grinding roller device suspended on the main machine plum blossom frame, it revolves around the vertical axis and rotates itself at the same time. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring, so that the scraper scoops up the material and sends it between the grinding roller and the grinding ring. The purpose of crushing the material is achieved due to the rolling and rolling of the grinding roller. After the material is ground, the fan blows air into the main housing, blowing up the powder, which is sorted by the analyzer placed above the grinding chamber. The coarse material falls into the grinding chamber for re-grinding, and the material that meets the specifications enters the cyclone collector with the wind flow, and is discharged through the powder outlet as the finished product. The internal reduction pendulum mill often runs continuously for a long time in the outdoor environment, so lubrication is very important, mainly for the main shaft, main shaft base bearing and grinding roller shaft bearing, analyzer bearing and fan bearing chamber to ensure the normal operation of the equipment and extend its service life.
