Abstract

The invention discloses a metal semi-autogenous-grinding ball mill lining plate. The lining plate is composed of a plurality of composite cylinder plates uniformly distributed according to the circumference of the semi-autogenous-grinding cylinder body and installed in the semi-autogenous-grinding cylinder body and composite lifting strips installed between every two composite cylinder plates; thecomposite cylinder platse comprise a rubber cylinder plate body with a plurality of embedding grooves, and the cylinder plate body is arc-shaped conforming to the circumference of the semi-autogenous-grinding cylinder body, and two installing lugs are arranged on the two sides of the cylinder plate body; and two rows of embedded groove bodies which are higher than the installing lugs are formed in the middle of the cylinder plate body, one of the rows of embedding groove bodies is higher than the other row of embedding groove body to form steps, the plurality of embedding grooves are formed in each row of embedding groove bodies, and wear-resistant alloy blocks are installed in the embedding grooves; and the composite lifting strips comprise rubber lifting strip bodies, a connecting framework is installed in the middle of the bottoms of the lifting strip bodies, the connecting framework is connected with the installing lugs, a plurality of embedding grooves are formed in the lifting strip bodies, and the wear-resistant alloy blocks are installed in the embedding grooves. According to the metal semi-autogenous-grinding ball mill lining plate, a mill body is high in efficiency, lowin power consumption, long in service life, low in noise, light in weight, convenient to install, safe and reliable.

Description

technical field

[0001] The invention relates to a metal ore semi-autogenous ball mill liner, which belongs to the technical field of mill equipment. Background technique

[0002] At present, the wear-resistant linings in large ball mills, semi-autogenous mills and autogenous mills used in the world's mineral processing industry for crushing materials are mainly made of metal castings. Generally speaking, for liners, the higher the hardness of the material, the better the wear resistance; the higher the strength of the material, the better the wear resistance; the higher the impact toughness (akv), the better the fracture resistance. Therefore, the prior art tries every means to improve the hardness and impact toughness of the metal liner. However, since the manufacturing process of the metal liner is mostly casting, due to the process, the hardness and toughness index of the cast liner is a pair of contradictions, that is, if the hardness increases and the wear resistance i...
