Abstract

The invention discloses a washing-resistant rubber lining for a cyclone and a preparation method thereof. The rubber lining is prepared by taking the nitrile rubber and butadiene rubber as matrix, taking polyurethane cellosilk, carbon fiber and polyamide fiber as the skeleton fiber, taking the sepiolite powder, carbon black and nano-aluminum oxide powder as filler, taking a aluminic ester couplingagent, liquid coumarone resin and modifying additive as the additive, and mixing the raw materials with anti-wearing auxiliary, a sulfurizing agent BPO and DM, wherein the anti-wearing auxiliary is prepared by mixing nitrile rubber powder, dioctyl phthalate, aluminium oxide, succinic acid and KH580; the modifying additive is prepared by mixing KH570, nanometer aluminum hydroxide, acetone and barium hydroxide. By arranging the rubber lining on the inner wall of the cyclone, thus the ore pulp directly impacts on the rubber lining, and the aim of protecting the inner wall of the cyclone is achieved; the rubber lining is easy to change after being damaged, and the service life of the cyclone is greatly prolonged.

Description

technical field [0001] The invention relates to a cyclone used in the mineral processing field, in particular to a scour-resistant rubber lining for a cyclone and a preparation method thereof. Background technique [0002] The cyclone is a common separation and classification equipment, and the principle of centrifugal sedimentation is commonly used. When the two-phase mixed liquid to be separated enters the cyclone tangentially from the periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent movement is generated. Due to the difference in particle size between coarse particles and fine particles, they are subjected to centrifugal force, centripetal buoyancy, fluid drag, etc., and are subjected to centrifugal sedimentation. Most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged from The overflow pipe is discharged, so as to achiev...
