Description
Technical Field
The utility model relates to a gold mine equipment technical field, concretely relates to novel wear-resisting disc rubbing crusher.
Background
The disc crusher is a device which is specified to be used in a gold ore sample crushing process of DZ/T0130.2-2006 geological mineral industry standard-rock mineral analysis sample preparation of the people's republic of China. The main working executing part consists of a movable grinding disc and a fixed grinding disc. The fixed grinding disc is connected with the machine body, and a feeding hole of the fixed grinding disc is communicated with a feeding channel on the machine body. The movable grinding disc is connected with a transmission main shaft on the machine body, and a fine adjustment locking device is arranged on the transmission main shaft, so that the movable grinding disc can be subjected to axial fine adjustment, and the discharge gap between the movable grinding disc and the fixed grinding disc is ensured to meet the granularity requirement of a mineral preparation sample. The conical curved surface on the traditional fixed grinding disc and the conical curved surface on the movable grinding disc jointly form a sample preparation machining cavity, and a prepared sample to be machined enters the machining cavity through the feeding hole. The conical curved surfaces of the movable grinding disc and the fixed grinding disc are respectively provided with 4 fixed convex lobes. The edges of the two grinding discs are provided with a grinding material shaping belt.
The traditional horizontal structure (the grinding disc surface is vertical to the horizontal plane) has the defects that: the materials between the convex lobes of the fixed grinding disc are lack of geometric constraint, so that the pressure of a processing material cavity is reduced, and the materials flow back. As a result, the rotation of the movable grinding disc can not drive all materials entering the grinding disc to be fully ground, and the lamination grinding and shearing grinding capacity is lower, so that the granularity of the prepared sample is influenced.
The invention patent with the application number of CN201210274856.9 discloses a disc grinder, which comprises a movable grinding disc and a fixed grinding disc, wherein two bosses are arranged on the central plane of a processing material cavity of the movable grinding disc, a material throwing groove is arranged between the two bosses, and convex lobes are arranged on the outer sides of the two bosses. The convex lobes are symmetrically distributed on a straight line. The curved surface at the top of the boss is a conical surface, and the outer side surface is a cylindrical surface. The top conical surface of the boss is parallel to the conical surface of the fixed grinding disc, and the diameter of the outer side cylindrical surface is equal to the diameter of the bottom surface of the top conical surface. The invention overcomes the defect that the movable millstone of the horizontal disc grinder can not drive all materials to be fully ground, realizes the laminated grinding in the processing material cavity of the millstone along the circumferential normal direction, ensures that the processed materials can be ground more finely, and provides a choice for the optimization of the disc grinder.
However, while solving the prior art problem, the technical scheme of this patent brings new defect, because the setting of boss makes the space in processing material chamber diminish, and then leads to work efficiency to descend.

Preferably, the rolling roller is also made of hard alloy materials.
Preferably, the outer wall of the central shaft between the transverse shafts of the adjacent rolling rolls is also fixedly connected with an ore material guiding device.
Preferably, the mineral aggregate guiding device is of a triangular pyramid structure, the bottom surface of the triangular pyramid structure is fixedly connected with the surface of the outer wall of the central shaft, and one side surface of the triangular pyramid structure is in sliding connection with the bottom surface of the processing material cavity of the movable grinding disc.
Preferably, the length of the mineral aggregate guiding device along the radial direction of the central shaft is greater than or equal to the length of the transverse shaft, and the average height of the two ends of the mineral aggregate guiding device relative to the bottom surface of the processing material cavity is greater than the height of the transverse shaft relative to the bottom surface of the processing material cavity of the movable grinding disc.
Preferably, the mineral aggregate guiding device is made of hard alloy materials and is detachably and fixedly connected with the central shaft.
Preferably, a plurality of spherical protrusions are uniformly arranged on the wall of the rolling roller.
This novel wear-resisting disc grinder's beneficial effect divide into 4 parts:
1. the working surface of the movable grinding disc and the fixed grinding disc is made of hard alloy materials, so that the wear resistance is greatly improved.
2. This novel roller mechanism that rolls that still is provided with can fully grind the entering processing material chamber, has improved work efficiency.
3. This is novel still to be equipped with mineral aggregate guider, has overcome prior art in the easy long-pending problem of staying at processing material chamber middle part of mineral aggregate.
4. This neotype rolls roller mechanism occupation space and is little, has overcome among the comparison file occupation space too much and has leaded to smashing the defect that efficiency descends.
