preparation example Construction

[0051] As further preferably, the preparation method of above-mentioned rubber material, comprises the following steps:

[0052] S1: The natural rubber is masticated separately, the masticating time is 110-130s, and the masticating temperature is 130-150°C;

[0053] S2: Add cis-1,4-polybutadiene rubber, polytetrafluoroethylene and wear-resistant agent to the natural rubber masticated in step S1 to continue masticating. The above masticating time is 50-60s. The temperature is 70-90°C;

[0054] S3: Add carbon black, aromatic oil, anti-aging agent, zinc oxide, stearic acid and processing aids to the mixture completed in step S2 for mixing and debinding. The above mixing time is 180-220s. 140~160℃;

[0055] S4: Cool the mixture that has been mixed in step S3 to below 23°C, and park it for more than 24 hours, add sulfur and a vulcanization accelerator to continue the second mixing and debinding, the above mixing temperature is 90-100°C, and the mixing time 170~190s;

[0056] S5...

Embodiment 1～3

[0062] Embodiments 1 to 3: according to the rubber material formula specified in Table 1,

[0063] S1: the natural rubber RSS1 was masticated separately at 140°C for 120s;

[0064] S2: Add cis-1,4-polybutadiene rubber, polytetrafluoroethylene and E2203-PU wear-resistant agent to the natural rubber after masticating, and continue masticating for 60 seconds at a temperature of 80°C;

[0065] S3: Add carbon black, aromatic oil, anti-aging agent, zinc oxide, stearic acid and processing aids to the masticated mixture for mixing and debinding, the mixing time is 200s, and the mixing temperature is 150°C;

[0066] S4: The mixture after mixing is cooled to below 23°C and parked for more than 24 hours, adding sulfur and vulcanization accelerator to continue the second mixing and debinding, the mixing temperature is 95°C, and the mixing time is 180s;

[0067] S5: Put the mixture obtained by kneading into the mold cavity. Under the condition of 185KGF, control the vulcanization temperat...

Embodiment 4

[0076] Embodiment 4: according to the formula of the concrete rubber material of embodiment 1,

[0077] S1: masticate natural rubber RSS1 alone at 130°C for 110s;

[0078] S2: Add cis-1,4-polybutadiene rubber, polytetrafluoroethylene and E2203-PU wear-resistant agent to the natural rubber after masticating, and continue masticating for 50 seconds at a temperature of 70°C;

[0079] S3: Add carbon black, aromatic oil, anti-aging agent, zinc oxide, stearic acid and processing aids to the mixture that has been masticated to carry out mixing and debinding. The mixing time is 180s, and the mixing temperature is 140°C;

Abstract

The invention provides a cutting resisting rubber composite liner plate structure for a ball grinding mill and relates to the field of grinding mill equipment. A rubber composite liner plate comprisesa liner plate body, a lifting strip and a bolt. The lifting strip is formed by compositing rubber, wear-resisting metal and a metal skeleton. The connecting face of the wear-resisting metal and the rubber is provided with wave-shaped round steel. The rubber material for preparing the rubber liner plate comprises natural rubber, cis-1,4 polybutadiene, carbon black, sulphur, zinc oxide, stearic acid, vulcanization accelerator, an aging-proof agent, arene, a processing agent, polytetrafluoroethylene and a wear-resisting agent. The prepared rubber liner plate has high wear resisting and cutting resisting properties, by means of the wave-shaped round steel, the connecting area of the wear-resisting metal and the rubber is increased, thus the connecting strength of adhesive is improved, and theservice life of the liner plate is prolonged.

Description

technical field [0001] The invention relates to the field of mill equipment, in particular to a cut-resistant rubber composite liner structure for a ball 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. The mill liner is used to protect the cylinder from the direct impact and friction of the grinding body and the material. At the same time, different forms of liner can be used to adjust the movement state of the grinding body to enhance the crushing of the material by the grinding body. It helps to improve the grinding efficiency of the mill and increase the output. In addition to protecting the cylinder, the...
