Abstract

The invention discloses an oblique swing pressurization external circulation mill. A central shaft frame is mounted at the bottom of a base of a milling main engine; milling rings are mounted at an upper part of the base; a cover barrel is mounted on the end surface of the base; a main engine feeding hole is formed in an upper cover of the cover barrel; a main engine discharging hole is formed in the bottom of the base near the central shaft frame and communicated with an external grading system through a pipeline; a lower part of a main-engine main shaft is arranged on the central shaft frame; a fixed roller frame connected with a material scraping frame is mounted at an upper end of the main-engine main shaft; the central shaft frame is sleeved with the material scraping frame; material scraping plates are mounted on the material scraping frame; milling roller devices are uniformly distributed around the circumference of the main-engine main shaft; each milling roller device comprises a milling roller sleeve, a milling roller and a milling roller shaft; the milling roller sleeves are obliquely hung on the fixed roller frame; the milling rollers obliquely lean on the milling rings; a material equalizing plate synchronously rotating and provided with a baffle edge is arranged above the fixed roller frame; a pressurization mechanism acting on the milling roller devices is arranged on the fixed roller frame. According to the mill, a finished product is separated by adopting external circulation, so that equipment is convenient to repair; a shovel blade mechanism is not arranged, so that the power consumption is reduced and the total power loss of the milling main engine is reduced.

Description

(1) Technical field: [0001] The invention relates to powder processing equipment, in particular to an oblique pendulum pressurized external circulation pulverizer. (two) background technology: [0002] The pulverizer is the most widely used equipment in the mineral powder industry, and the most representative equipment is the Raymond mill. [0003] The general structure of the main engine of Raymond mill is as follows: the base of the main engine is equipped with a hollow central shaft frame, a coaxial grinding ring and a cover tube, the main shaft of the main machine is set in the central shaft frame, and the upper end of the main shaft extending outside the central shaft frame is installed. There is a fixed roller stand (or plum blossom stand), on which a plurality of grinding roller assemblies parallel to the central axis and distributed in a circle are hanged evenly through the hinge device. The grinding roller assembly consists of a grinding roller sleeve and a grinding...
