Description
Technical field
The present invention relates to a kind of ball mill barrel liner plate, be meant a kind of stepped shell liner for ball mill especially; Belong to the crushing grinding mechanical field.
Background technology
The shell liner of ball mill can be divided into crest part and bottom parts.The main effect of crest part is that abrading-ball is taken to certain altitude, so that abrading-ball is fallen suitable position fragmentation and grinding material expeditiously; The main effect of bottom parts is the barrel-type casing of protection ball mill, and barrel-type casing is not contacted with abrading-ball with mineral aggregate, thereby not by mineral aggregate and abrading-ball wear down.The crest of shell liner part is most important to the influence of the crushing grinding efficient of ball mill and unit-hour output.So how to guarantee the crest of shell liner partly being difficult for being worn, is high efficiency and the key steady in a long-term thereof that improves the service life of shell liner and keep ball mill crushing grinding material.
Existing ball mill barrel liner plate waveform, to how alleviating the abrasion deformation of liner plate crest part, do not give due attention, the liner plate that causes existing various waveforms, after using the short period, crest height and shape are just because of great changes have taken place in heavy wear, and the dribbling of liner plate descends highly thereupon, and ball mill efficient broken and grinding material obviously descends.In bargh, cement plant, thermal power plant, can often see because of the undue ball grinding machine lining board of seriously scrapping of crest distortion.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art and provide a kind of simple and reasonable, processing system easily, can effectively reduce the deterioration of ball mill barrel liner plate crest, keep the crest waveform good, keep the liner plate dribbling highly steady in a long-term, the fragmentation and the grinding efficiency long-term stability that keep ball mill, the stepped shell liner for ball mill that increase substantially the service life of liner plate.
Stepped shell liner for ball mill of the present invention, the crest of liner plate are step, and a crest is made of at least two steps.
Among the present invention, the height of described step is all greater than the radius of minor diameter abrading-ball, less than the radius of major diameter abrading-ball.
Among the present invention, the width of described step is all greater than the radius of minor diameter abrading-ball.
Among the present invention, described step crest, the height and the width of each step can be the same or different, the height of step number, each step and width are determined according to factors such as the diameter of type, length, diameter and the rotating speed of ball mill, the characteristic of going into the ore grinding material and granularity, the indexs such as fineness requirement that go out the ore grinding material, abrading-ball and proportionings.
The present invention is owing to adopt said structure, and the crest of liner plate is a step, and crest is made of two or more step; When liner plate moved clockwise, the side of each step was used for stoping the tangential relative motion of minor diameter abrading-ball, made the minor diameter abrading-ball only produce short-range friction with the end face of step; The end face of each step supports the minor diameter abrading-ball and is stacked into certain altitude, makes most of major diameter abrading-ball can only touch the minor diameter abrading-ball and isolates with crest; The drift angle of each step makes the major diameter abrading-ball that touches roll along drift angle, and the change sliding friction is rolling friction, and the major diameter abrading-ball do not reach the side of step, is difficult to touch end face.Thus, the wearing and tearing of crest greatly alleviate, and increase substantially the service life of liner plate.
Step waveform of the present invention, the side height of each step be greater than the radius of minor diameter abrading-ball, but less than the radius of major diameter abrading-ball, and the end face width of each step is greater than the radius of minor diameter abrading-ball, greater than, be less than or equal to the radius of major diameter abrading-ball; The side height of each step and end face width can be identical also can be inequality; According to factors such as the diameter of type, length, diameter and the rotating speed of ball mill, the characteristic of going into the ore grinding material and granularity, the indexs such as fineness requirement that go out the ore grinding material, abrading-ball and proportionings; the size of appropriate design step number and each step; can not only increase substantially the service life of liner plate; can also under the situation that reduces ball load, improve the output of ball mill and the Grinding Quality of mineral aggregate, obtain and save material, save electric energy, improve output, improve the quality of products, reduce overall economic efficiencies such as shutting down maintenance.
In sum; the deterioration that the present invention is simple and reasonable, the processing system is easy, can effectively reduce ball mill barrel liner plate crest; keep the crest waveform good; keep the liner plate dribbling highly steady in a long-term; keep the fragmentation and the grinding efficiency long-term stability of ball mill, increase substantially the service life of liner plate, can effectively save material, saves electric energy, improves output, improve the quality of products, reduce maintenance downtime; can with the supporting use of the ball mill of various models, be suitable for suitability for industrialized production.
Description of drawings
Accompanying drawing 1 is a principle of the invention schematic diagram.
