Abstract

The invention provides a resistant rubber lining plate, and relates to the field of mill equipment. The rubber lining plate comprises a lining plate body, lifting bars and bolts, wherein the lifting bars comprise high lifting bars and low lifting bars, and the lifting bars and the lining plate body are fixed on the inner wall of a mill cylinder through the bolts; the high lifting bars and the lowlifting bars are alternately distributed on the lining plate body at the periphery of the inner wall of the mill cylinder. The rubber materials for preparing the rubber lining plate comprise natural rubber, cis-1,4-polybutadiene, carbon black, sulfur, zinc oxide, stearic acid, a vulcanization accelerator, an anti-aging agent, aromatic oil, a processing agent, polytetrafluoroethylene and a wear-resistant agent; the cut-resistant rubber material is prepared by controlling the temperature and the time of plastication and mixing and controlling vulcanization process. The technical problem that thecut resistance of the rubber lining plate in the prior art is low is solved, the prepared rubber lining plate has high resistance and cut resistance, and the service life of the rubber lining plate is prolonged.

Description

technical field [0001] The invention relates to the field of mill equipment, in particular to a rubber liner structure for a mill. Background technique [0002] Mills include semi-autogenous mills, ball mills, and the like. The main purpose of mill grinding is to grind the ore finely in the ball mill, so that the useful minerals and gangue and useful minerals and useful minerals can be separated into monomers. The so-called monomer dissociation means that useful minerals do not contain gangue, and gangue does not contain useful minerals. With the development of grinding technology and mill (semi-autogenous mill, ball mill) manufacturing technology, the size of grinding media and ore feeding has gradually increased, and the impact and wear on the mill liner have increased exponentially. Restricted by materials and production techniques, traditional manganese steel and alloy steel cast liners have reached their performance limits. [0003] Due to the high wear resistance, h...
