Abstract

The utility model relates to a tapered disc type ore milling machine, which is provided with a rotary body 2 with the huge weight (relative to the other parts of the machine), wherein, the lower part of the rotary body 2 forms an umbrella shape and is provided with an upper lining plate 5 which also forms the umbrella shape, and then, the rotary body 2 is arranged on the base 9 in the shape of a taper; the base 9 is also provided with a lower lining plate 11 which also forms the taper shape; the rotary body 2 and the base 9 are correspondingly fixed with a bearing, and the rotary body is also provided with a big gear 10 which is driven to rotate by a pinion gear 6 which is engaged with the big gear 10. The surfaces of the upper lining plate and the lower lining plate are in the shape of the corrugation; the materials from a feed inlet can be subjected to the huge pressure of the rotary body and the upper lining plate, and the materials can be pressed and can be subjected to the shear stress. The milling is rapid. The tapered disc type ore milling machine has the advantages of simple structure, light weight, small noise, high productivity and easy manufacture and maintenance.

Description

Tapered disc type milling pit

The utility model relates to a kind of cone disk type ore mill, is used for ground ore and construction material.

The ore mill of using in the metallurgical industry now has the ball mill of being done milling medium by steel ball, and useful rod iron is made the rod mill of milling medium, reaches the tube mill that building material industry is used.These grinding machines are from great, and consumed power is big, noise big (considerably beyond state-set standard).Reason is that machine construction is unreasonable, and huge body only plays carrier function, promptly is used for carrying liner plate, steel ball (rod iron) and grinding charge material, is not used for direct ore grinding.Ore grinding mainly is by steel ball (rod iron).Be exactly autogenous tumbling mill, though there is not steel ball (rod iron) deadweight also very big, this deadweight also is to be used for working as carrier, directly ore grinding.

The purpose of this utility model provides a kind of cone disk type ore mill, and the weight of the rotation upper body of this machine and last liner plate thereof can be directly used in ore grinding.

The purpose of this utility model is achieved in that

There is the rotary body bottom of very big weight (for other pieces on the machine) to be umbrella shape, is equipped with the umbrella shape liner plate on it; Rotary body and on liner plate be placed in the base that is taper and also be on the following liner plate of taper.Be equipped with gear wheel on the week of rotary body garden, this gear again with the pinion and the driven rotary of driven by motor, thereby make the rotary body rotation, when from rotary body middle part throat-fed, material is just ground like this, discharge around the rotary body then.

Because rotary body has the very big weight of relative machine other pieces, add and pacify thereon the weight of liner plate and the weight of other pieces can act on the grinding charge material, the grinding charge material is subjected to weight like this, the shearing force that material is subjected to when adding the rotary body rotation, so fragmentation and grinding efficiency height, under the treating capacity same case, its volume weight is less than garden ball tube mill and rod mill and autogenous tumbling mill, and the noise of ore grinding also significantly reduces simultaneously.Because simple in structure, productivity ratio is high, also just brings cost low, the ore grinding expense is also low.

Further introduce the utility model below by accompanying drawing:

Accompanying drawing 1 is a vertical view of the present utility model;

Accompanying drawing 2 is an A-A cutaway view of the present utility model.

Can see that from accompanying drawing 2 pairs of other pieces of rotary body have huge weight, it is the garden cylindricality in general, and its bottom is umbrella, and the last liner plate 5 that also is umbrella is installed above.Have charging aperture 1 at its middle part, the grinding charge material is from input here.Also be equipped with gear wheel 10 along garden Zhou Fangxiang, it is meshed with pinion 6 again, therefore when motor 7 rotates, by pinion 6, drives gear wheel 10 and therefore also just makes rotary body 2 rotations.The following of rotary body 2 is base 9, and it is taper, and the following liner plate 11 that also is same taper is installed on it.Last liner plate 5 and following liner plate 11 all are separately fixed on rotary body 2 and the base 9 by bolt 4, and the liner plate surface is corrugated up and down.At the center of base 9 bearing 3 is arranged, it be for rotary body 2 and on last liner plate 5 and base 9 and on following liner plate 11 relative fixed establish.Can also see that from accompanying drawing in order to be beneficial to the ore uniform distribution of coming in from charging aperture, last liner plate 4 is shaped on horn mouth 12 in the part, middle part.For the ease of making and installing, liner plate manufactures polylith up and down again, and the centre links up with key 8 then.

After material is come in from charging aperture 1, rotary body 2 by motor 7 by big pinion 10 and 6 driven rotary, material moves downward along the gap that forms between the liner plate up and down, material is subjected to the pressure of rotary body 2 and the 5 huge weight formation of last liner plate during this, add the shear stress that rotation causes to material, make material obtain pulverizing and grinding, the material that mill is good is discharged around base 9.Corrugated is made on the liner plate surface up and down, and this helps promoting material on the one hand with rotary body 2 rotations, also helps material on the other hand and moves downward.

Claims

1, a kind of cone disk type ore mill is characterized by: rotary body 2 bottoms are umbrella, and the last liner plate 5 that also is umbrella is installed on it, and rotary body 2 and last liner plate 5 are placed on the base 9 and following liner plate 11 that is taper.

2, ore mill as claimed in claim 1 is characterized by: there is gear wheel 10 in rotary body 2 gardens on week, there is charging aperture 1 at the middle part.
