Abstract
The utility model relates to a vertical spiral agitating ball mill, used for processing the milling of the fine fraction mineral. The vertical spiral agitating ball mill carries out anti-wear processing towards blades of a main shaft. A cone structure is at the bottom of the blades of the main shaft, and a main shaft hanging part is arranged. The stability of the running of the whole machine is enhanced, the vibration is eliminated and the service life of the blades is enhanced.
Description
The utility model is a kind of vertical helical agitating ball mill.Be particularly suitable for handling the mineral of the difficult mill of fine fraction.
Traditional grinding machinery is horizontal.The grinding of ore is by the cylindrical shell running, drives the motion of milling medium steel ball and carries out.This grinding machine is because the ore grinding principle has determined hold ball rate not surpass 48%, and ball also has certain " dead band " when the grinding machine internal motion, so grinding efficiency low energy expenditure height, the fine grinding of incompatibility mineral.
The novel vertical ball mill was all successively studied by the U.S., Japan in recent years, and maximum processing ore ability is 50t/h.This kind ball mill has advantages such as grinding efficiency height, power consumption are low to handling the fine fraction mineral.
The domestic unit application has also the been arranged patent of vertical ball mill.The one, Qinhuangdao Ferrous Metal Metallurgical Mine Design Inst., the patent No. is 87214940.4, two, Changsha Mining and Metallurgy Research Inst., Ministry of Metallurgical Industr, the patent No. is 90200524.3.The former has limited the disposal ability of this machine because of barrel diameter is little, add whole machine installation on multi-functional under casing, and the high running of center of gravity is unstable.The helical blade life-span is short, is difficult to adapt to the industrialness production requirement.And the latter does not possess the function of wet grinding for dry milling machinery.
It is wear-resisting that the purpose of this utility model provides a kind of main shaft helical blade, long service life, vibrate little, the agitated ball mill that disposal ability is big.
For realizing the purpose of this utility model, now in conjunction with the accompanying drawings.As shown in the figure, the utility model is by motor 1, and cycloidal planetary gear speed reducer 2, bearing suspension part 3, pin shaft joint 4, main shaft helical blade 5, centering cone 6, cylindrical shell 10, (comprising overflow launder 7, tube skin 8, tube lining 9, mineral-feeding pipe 11) concrete pedestal 12 are formed.
Operation principle of the present utility model is: by pin coupler moment of torsion is passed to minor axis on the bearing suspension part 3 by motor 1 and cycloidal planetary gear speed reducer 2, and then the shaft coupling and the main shaft that connect firmly by bolt link, drive helical blade rotation on the main shaft, make the steel ball in the cylindrical shell produce motion, reach effect the mineral fine grinding.
3 tops, the utility model bearing suspension part are connected with reductor 2 bolts of lower base, and bottom and concrete pedestal 12 Bolt Connection make complete machine be fixed on the concrete pedestal by the bearing suspension part, have improved the stability of operation, have eliminated vibration.Be provided with the bearing bag at center, bearing suspension part, the inside has radially and thrust bearing, thus eliminated main shaft rotate produce axially and radial load to the impact of reductor.
The utility model is in order thoroughly to solve the influence of main shaft axial force to reductor, and the bearing suspension part is provided with minor axis, and speed reducer output shaft is with adopting pin coupler 4 to transmit moment of torsion between the minor axis of bearing suspension part, and the bottom connects with shaft coupling and main shaft helical blade.
The utility model is provided with a centering cone at main shaft helical blade lower curtate, and the high 150-200mm of cone, diameter are 250-300mm, and the cone angle is 100-120 °.Solid conical is the garden wimble structure, and in order to improve service life, material is a Cr35Mo cast steel, and at the Fe-05 of surface overlaying 3～5mm antifriction alloy powder agglomates.
The utility model helical blade Cr35Mo cast steel, and carry out Wear-resistant Treatment, the Fe-05 antifriction alloy powder agglomates of built-up welding 3～5mm at edge easy to wear and blade surface.
Tube lining of the present utility model adopts ring-like potassium steel liner, and the thickness upper-thin-lower-thick is synchronous with service life about guaranteeing.Between two joint liners is the seam connecting mode, goes up most simultaneously between joint liner plate and the tube skin and is provided with sealing ring, to prevent advancing foreign material between a skin and the liner plate, causes difficulty to replacing.
The utility model barrel is provided with two feed ports 11, is provided with removable double-edged fine-toothed comb in the feed port, enters mineral-feeding pipe to prevent steel ball, and the double-edged fine-toothed comb installation site is lower than liner plate upper surface 50-60mm.Make the part ball enter this space, play the effect of conservation of nature giving the ore deposit double-edged fine-toothed comb.
The utility model top is ring-like overflow discharge trough 7, is used for collecting the ore pulp after the grinding.
The utility model has following advantage and effect:
One, the life-span that experiment showed, this machine spindle helical blade can be brought up to more than 2000 hours from 500 hours of original ordinary steel.Possessed the condition that industrialness is produced that is applied to.
Two, this equipment has been eliminated the vibration problem in the operation process, complete machine stable and reliable operation.
Three, the utility model compact conformation, floor space is little, and installation, dismounting and maintenance are all very convenient.
Four, this equipment can improve ball-milling treatment ability 3.2t/h, and grade improves 0.22%, has solved the handling problem of the difficult ore grinding of fine fraction.
