Abstract
The utility model relates to a circular trench grading composition lining plate. The utility model is characterized in that the lining plate is a whole cast square disk type structure, the upper surface of the lining plate is an inclined surface, concave grooves are arranged on the surface, and a side of the lower end of the inclined surface is provided with an arc protrusion. The utility model has a simple structure, can overcome the disadvantages of present grading lining plates and circular trench lining plates, and is a replacement type lining plate.
Description
The utility model belongs to the ball mill equipment parts in the grinding technology, particularly a kind of circular groove classification composite liner.
Ball mill is a solid material milling equipment the most frequently used in the grinding technology, and rotating grinding mill barrel inwall is equipped with shell liner around the axle center, mainly plays the protection grinding mill barrel, and the abrasive body motion state that is filled in the grinding machine inner space is had certain influence.The form direct relation of ball milling shell liner the output and the quality of grinding machine.Shell liner various informative, have ten surplus more than the kind.Wherein circular groove liner plate and classifying lining board be that range of application is wide, result of use two kinds of liner plates preferably.Circular groove liner plate exists because of often maintaining material in the circular groove, can avoid abrasive body directly to impact liner plate, reduces both attrition; Milling area in circular groove between abrasive body and liner plate increases, and produces additional abrasive action, pulverizes and grinding efficiency thereby improve; The disengaging angle of abrasive body is bigger than general liner plate, can be significantly energy-conservation; Because the wearing and tearing of groove each several part are impartial, can keep the usefulness of grinding and grinding constant, and the steel scrap rate are very low; Circular groove liner plate also can reduce owing to abrasive body being promoted uneven pulsation moment and the noise that produces.The classifying mechanism of classifying lining board is when moving abrasive body contacts with the liner plate surface, the liner plate inclined plane (along drum shaft to) horizontal component that acts on abrasive body is proportional to the cube of abrasive body diameter, and abrasive body along the axially movable resistance of cylindrical shell be proportional to the abrasive body diameter square, be that the little abrasive body axial moving force of the big abrasive body diameter group of diameter is wanted greatly, translational speed is also fast.Like this, at mill running after a period of time, big abrasive body is just shifted to feed end, and the little discharge end that then is pushed to is so abrasive body has obtained rational classification.Classifying lining board can effectively be eliminated the unreasonable distribution phenomenon that abrasive body makes progress in drum shaft in the mill, the average ball diameter that makes abrasive body along drum shaft to from the feed end to the discharge end, successively decreasing successively, become the anti-positive classification that is classified as, with adapted by the descending technology regularity of distribution of the average grain diameter of grinding material, thereby improve mill efficiency; For compound mill, after adopting classifying lining board since the specification of abrasive body can with adapted by the particle diameter of grinding material, cause the effect of partition device for barn to reduce relatively, can suitably reduce the storehouse number, to increase the dischargeable capacity of grinding machine, reduce flowing resistance; Because abrasive body distributes rationally in the mill, also can reduce the grinding phenomenon.Also there are two shortcomings in classifying lining board: the one, and liner plate thickness is big, and the grinding machine dischargeable capacity is reduced; The 2nd, adjacent two blocks of liner plates and abrasive body have formed one jointly and have been similar to leg-of-mutton dead material district, have reduced the effective area of grinding machine inside, more than 2 output that influence grinding machine to a certain extent, must be overcome.
The purpose of this utility model provides a kind of circular groove classification composite liner, gives full play to the advantage of above-mentioned two kinds of liner plates, overcomes both shortcoming and defect.
The purpose of this utility model is achieved in that
Liner plate is a monoblock cast square plate formula structure, is the inclined plane above the liner plate body, is arranged with concave channels on this face, and low side one side on inclined plane has an arc-shaped protrusions.
The concave channels that arrange on described inclined plane is 1-6.
The function of the utility model composite liner has following characteristics and advantage:
1. often maintain material in the circular groove and exist, can avoid abrasive body directly to impact liner plate, reduce both
Attrition;
2. the milling area between abrasive body and liner plate increases in circular groove, produces additional abrasive action, thereby
Improve and pulverize and grinding efficiency;
3. the disengaging angle of abrasive body is bigger than general liner plate, can be significantly energy-conservation;
4. the steel scrap rate is very low, compares with the generic hierarchical liner plate, and liner plate is thinner; Along with the impartial mill of groove each several part
Decrease, the grinding machine dischargeable capacity is constantly increased, and the usefulness of grinding and grinding remains unchanged;
5. ring-shaped groove can reduce owing to abrasive body being promoted uneven pulsation moment and the noise that produces.
6. the liner plate upper surface can effectively be eliminated the unreasonable distribution phenomenon of abrasive body in the mill along the cylindrical shell axioversion, makes
The average ball diameter of abrasive body along drum shaft to from the feed end to the discharge end, successively decreasing successively.Becoming counter just being classified as divides
Level and is adapted by the descending technology regularity of distribution of the average grain diameter of grinding material, thereby improves powder
Mill efficient;
7. for compound mill, after adopting composite liner since the specification of abrasive body can with by grinding material
Particle diameter adapt, cause the effect of partition device for barn to reduce relatively, can suitably reduce the storehouse number, to increase mill
The dischargeable capacity of machine reduces flowing resistance;
8. because the interior abrasive body of mill distributes rationally, can reduce the grinding phenomenon, help to improve the grinding of grinding machine
Efficient;
9. to have eliminated the generic hierarchical liner plate common with abrasive body above adjacent two contact-making surface for this composite liner
The dead material district that forms;
Below in conjunction with description of drawings embodiment:
Fig. 1 circular groove classification composite liner structural representation
This composite liner is the monoblock cast tray type structure, and it is inclined plane 1 above liner plate body, is arranged with a plurality of concave channels 2 on this face, is expressed as 2 in the present embodiment, can be provided with a plurality of as required.Low side one side on inclined plane has an arc-shaped protrusions 3.
This composite liner is the device that solves the problem that traditional ball mill mill efficiency is low, energy consumption is high, it be used for the fine grinding storehouse improve the mill efficiency of grinding machine, can be significantly energy-conservation; Adopt this new technology circular groove classification composite liner (looped-groove classified compound line) only need change shell liner to original grinding machine and get final product, the retrofit work amount is little.Be specially adapted to carrying of traditional ball mill and produce the consumption-reducing technological transformation.
This liner plate is the shell liner of ball mill, and the available bolt of using is connected with cylindrical shell.
