【発明の詳細な説明】 〔産業上の利用分野） 本発明は、回転する鉱物破壊機に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a rotating mineral destruction machine.

く左右される。A previous example of a rotating mineral destroyer is described by US Pat. No. 3,970,257. This specification describes a mineral crusher comprising a rotor positioned within a housing. The minerals are fed into the rotor and thrown at high speed against the housing walls (the walls themselves being aligned with the minerals). Mineral-to-mineral contact is highly dependent on the grinding action of the equipment.

限定された接近を介して取り外され、固定されている。US Pat. No. 4,586,663 discusses the problem of vertical top surface wear. Similar, if not more severe, wear problems apply to horizontal surfaces. There are a number of problems with the above-mentioned precepts for which there are no obvious solutions. Rotors are subject to extreme conditions of wear and mechanical stress, as recognized from the same functional understanding. It has been previously assumed that strong tensile resistant materials must be used on the top, bottom and sides of the rotor due to the extreme mechanical forces that the rotor must withstand. Conventionally constructed rotors are therefore configured as one-piece cages with the only access to the wear section being through the upper ports or outlets on the sides of the rotor. Due to insufficient access, protective alignments for the upper and lower inner surfaces of the rotor are provided separately and can be removed and fixed through the very limited access afforded by the inlet and outlet sections. ing.

外側表面が最小量の突出で可能な限り円滑であることも
また望まれる。The sides of the rotor are subject to constant frictional contact with materials that may be crushed, and grooves on the side walls of the rotor should be avoided if they can become a focus of wear. It is also desirable that the outer surface of the rotor be as smooth as possible with a minimal amount of protrusion.
