Description

Ore raw material thickness sieving mechanism Technical Field The application relates to the technical field of ore equipment, in particular to an ore raw material thickness screening device. Background Mineral powder is one of the common raw materials in the building material industry, and when the mineral powder is prepared, the mineral powder is required to be crushed and ground by a grinder. In the prior art, when grinding the ore raw materials, often direct leading-in material way of ore raw materials, transport mechanism in the material way carries the ore raw materials to grind to the mill, however, the general particle size distribution of ore raw materials of exploitation is uneven, though grind the mill possesses certain crushing capacity, when the inside wearing and tearing of mill is got into to the great ore of granularity, can lead to the moment increase that the grinding roller bore to lead to the grinding roller wearing and tearing, bearing load increases, causes equipment trouble such as main shaft fracture even when serious, and the life of mill reduces, has obvious inadequately. Disclosure of utility model In order to improve the service life of the grinding machine, the application provides an ore raw material thickness screening device. The application provides an ore raw material thickness screening device which adopts the following technical scheme: The utility model provides an ore raw material thickness sieving mechanism, includes the processing case, the feed inlet has been seted up to the one end of processing case, and the discharge gate with grind the machine intercommunication has been seted up to the other end, the inside baffle that is provided with of processing case, the terminal surface that the baffle is relative with the processing case inside wall encloses and closes and form screening district and collection district, the feed inlet with the discharge gate all sets up screening district, screening district has set gradually first screen cloth and second screen cloth along vertical direction, the aperture of first screen cloth is greater than the aperture of second screen cloth, first screen cloth with the second screen cloth is all followed processing case width direction slope sets up, first entry and second entry have been seted up on the baffle, first entry intercommunication first screen cloth upper surface with collection district, the second entry intercommunication second screen cloth upper surface with collection district. Through adopting above-mentioned technical scheme, after the ore raw materials gets into the screening district from the feed inlet, make the ore of different particle diameters roll screening along the screen cloth surface under the action of gravity through first screen cloth and second screen cloth, the big aperture of first screen cloth sieves out the great ore of granularity earlier and falls into the collecting region through first entry, the surplus ore continues to sieve out the medium-sized ore of granularity through the aperture of second screen cloth and falls into the collecting region through the second entry, finally accord with the tiny ore that the particle diameter required gets into the mill from the export, thereby avoided the great ore of granularity directly getting into the mill and lead to the grinding roller to bear moment increase, wearing and tearing aggravation and bearing load too high problem, effectively reduced the probability of occurrence of equipment trouble such as main shaft fracture, the life of mill has been prolonged. Optionally, be provided with first broken subassembly and the broken subassembly of second in the collection district, first broken subassembly sets up first entry with between the second entry, the broken subassembly of second sets up the below of second entry, the treatment box surface is provided with the transfer case, the transfer mouth has been seted up to collection district bottom, the one end of transfer case seted up with the recovery mouth of transfer mouth intercommunication, the other end intercommunication be provided with the conveying pipe of feed inlet intercommunication, be provided with in the transfer case with the ore by the collection district transport to transfer the subassembly in the feed inlet. Through adopting above-mentioned technical scheme, after the ore that does not accord with the grinding machine particle diameter demand gets into the collection district, first broken subassembly and second broken subassembly are broken the ore in proper order for the particle diameter of big granule ore or well granule's ore is broken to the particle diameter that can accord with the second screen cloth aperture requirement, the ore after the breakage returns the feed inlet through transporting the subassembly and takes part in screening again, so make can't get into grinding machine after the breakage through big granule and the medium granule ore of first screen cloth an
