Abstract

The invention provides pulping equipment based on shearing, pulp filtering and coarse and fine ball milling in sequence. The pulping equipment mainly comprises a pulp generation device, a power driving device, a shearing and pulp filtering device consisting of a millstone A, a screen drum and an anti-overflow cover, a coarse and fine ball milling device consisting of an annular disc, a millstone Band a millstone C, and an anti-settling crushing device mainly consisting of an impeller rotor. The equipment is characterized in that slurry is firstly sheared, crushed, decomposed and filtered, andthen subjected to coarse and fine high-pressure double grinding. Shearing, crushing, decomposing and filtering of slurry are achieved through the shearing and pulp filtering device, coarse and fine double-grinding and high-pressure grinding of the slurry are achieved through the coarse and fine ball milling device, and ground pulp is prevented from depositing and impacting, crushing and grindingthrough the anti-settling crushing device.

Description

technical field [0001] The present invention relates to a kind of refining equipment based on firstly cutting and filtering pulp and then coarse and fine ball milling, especially relates to a kind of generation and output of pulp through a refining generation device, and a power drive device is a shearing and filtering device, a coarse and fine ball mill The device and the anti-sedimentation crushing device provide continuous power. The shearing, crushing, decomposition and filtration of the slurry is realized through the shearing and filtering device.
