The ball mill is the most commonly utilized products in sector grinding, the grid kind ball mill and overflow ball millis utilised in the EPTral processing industry and other EPTT sectors .Dry type grid variety ball mill is primarily utilised for EPTT milling, largely employed for grinding components EPTT.

Composition of ball mill

The ball mill is typically composed of cylinder, liner, feeder, hollow shaft, bearing, EPTT device and lubrication system. The framework of the ball mill is introduced with the case in point of the 3200x5400mm overflow ball mill underneath.

one)CylinEPTTof ball mill

The cylinder is welded by a number of thick thirty-32mm metal plates, with flange plates welded at each ends so as to join to the casting stop handles. The cylinEPTTis outfitted with a replacement liner. In orEPTTto make the liner make contact with tightly with the cylinEPTTand buffer the influence of the metal ball on the cylinder, plywood is used between the liner and the inner wall of the cylinder. In orEPTTto faXiHu (West EPT) Dis.Hu (West EPT) Dis.tate the alternative of the lining and the inner situation of the cylinder, a manhole is opened on the cylinEPTTbody. The manhole is mostly rectangular, and the size is EPTTly 350-550mm.

2)Feeding part of ball mill

The feeding component is composed of an conclude cover with a hollow shaft neck, a joint feeEPTT, a supporter-formed liner and a shaft neck internal sleeve , and so on. The inner neck of the hollow shaft can stop the sporting of the internal area of the axle neck. The internal floor of the inner sleeve is spiral and helps to feed. The feeEPTTis bolted to the finish of the internal sleeve. The EPTT use of the joint feeder, adopted by the drum feeEPTTand worm feeder, and so on.

3)Discharge component of ball mill

The discharging component is made up o the conclude include of the hollow neck, the wedge , the cEPTTr liner and the inner sleeve of the axle neck, and radial bars are positioned on the inner wall of the conclude include, which is equivalent to the partition board. There is a latticed plate in between each and every of the two bars and is pressed and mounted with a wedge. Wedge iron by the screw by means of the wall on the fastening ribs on the end protect. The cEPTTr element makes use of the cEPTTr liner to hold all the grid liners. The internal sleeve of the hollow shaft neck is made of a trumpet shaped blade at one particular end of the discharge grid to XiHu (West EPT) Dis.Hu (West EPT) Dis. the pulp naughty from the partition board to circulation down the blade. The EPTT discharge EPT is firmly fixed on the flange plate of the barrel as nicely as the feeding element.

4)EPTT component of ball mill

The EPTT component is composed of large EPT wheel, pinion, EPTT shaft and elastic coupling. The mill barrel is EPTn by the EPT EPT gadget by the motor by way of the couplings. The EPT EPT unit is composed of a EPT ring and a EPTT EPT put in at the stop of the barrel. The EPTT EPT is mounted on the EPT shaft, and the EPT shaft is supported on the two double row cEPTTring rolling bearings in the bearing seat. The EPT include is completely coated with a dustproof go over.

5)Major bearing of ball mill

The hollow Journal of the ball mill is supported on the self aligning major sliding bearing. The main bearing is created up of the reduced bearing seat , the bearing cap , the decrease bearing bush with the Babbit alloy , the cylindrical pin and the sealing ring. The bearing pedestal and the lower axle bush are made of spherical make contact with in orEPTTto compensate for the set up mistake. There is a cylindrical pin in the cEPTTr of the base and the axle of the axle bush, which helps prevent the Bush from sliding out of the bearing seat. The oil EPTTring the pipe is fanned into the journal bearing on the neck of the nozzle, and the oil after the lubrication is returned to the tank by the exhaust pipe.

Overflow ball and grid ball mill

The framework of the overflow ball mill is basically the exact same as that of the grid ball mill , but there is no material row in the cylinEPTTend, and the reverse spiral blade is installed on the interior floor of the hollow neck bushing, which can return the pellets and coarse ore blocks in the pulp back to the mill.

Compared with the overflow type ball mill, the advantages of grid variety ball mill is the discharge pulp area is low, the pulp can pass quickly, can lessen the overgrinding the ball can be loaded, and the ball will not be discharged, good operating circumstances can be shaped unEPTTthe exact same problems, the manufacturing potential is greater. And the EPTT use is low, it is somewhat complicated construction. But the overflow variety ball mill has the rewards of simple structure, administration and routine maintenance are handy, so the operation rate is fairly higher. Normally, the overflow kind ball mill should be employed with the good grinding fineness, and the grinEPTTtype ball mill is ideal for the coarse grinding fineness. (The adverse outcomes of extreme grinding on ore dressing can be avoided ).

Operating theory of ball mills

-The primary element of overflow ball mill is a rotary cylinEPTTsupported by bearings which is revolved by transmitting EPTTry. EPTs are place in cylinEPTTthrough the feed opening and then thoroughly grinded. The falling training course of iron balls and ores can generate enormous slipping affect and autogenous grinding. The ongoing feeding of ores can EPT considerable force to make ores shift from feed opening towards discharge opening. Lastly, acceptable particles are discharged from the discharge opening. Hollow shaft with the anti-spiral blade returns the steel ball and the coarse ore.

-The primary part of grid ball mill is a rotation cylinEPTTrotating little by little by the EPTT device. The substance is fed from the cylinEPTTinlet and grinded by the affect of metal ball and ore and self-grinding. Because of to the constantly feeding content, the force pushes substance to the outlet and the grinded substance is discharged from the cylinEPTToutlet. In soaked grinding, substance is taken out by h2o in dry grinding, the substance is taken out by air. The grid set up in the outlet of mill is relied for pressured discharge. Lower pulp surface area in cylinEPTTreduces the ore in excess of-grinding, and avoid the metal ball out. UnEPTTthe exact same production circumstances, generation ability of grid mill is larger than overflow ball mill’s.

Dry sort ball mill is a grid ball mill of horizontal rotating unit with outer EPT EPT system, two hoppers. EPTs evenly spirally EPTTr into the initial hopper by means of hollow shaft, the warehouse has stepped lining board or corrugated liner board and different measurements of steel balls, the centrifugal drive made by cylinEPTTrotation delivers the metal balls to a particular height, then the slipping balls pound and grind resources. After the tough grinding in the initial hopper, by monolayer partition panel, the material will EPTTr the next hopper, which has airplane scale board with steel balls inside of to grind content. The powEPTTis discharged from grid plate and grinding procedure is concluded.

Liner and grinding medium of ball mill

liners and grinding media are EPTTant factors of ball mills or indispensable for operate, they are effortless to wear and take in a good deal.

1)Liners of ball mill

Liner materials can be manufactured of tough chromium metal, substantial manganese steel alloy cast iron, rubber and magnetic lining etc.. EPT manganese steel has ample affect toughness, and it can harden and become challenging and wearable when subjected to a specific impact. For that reason, high manganese steel is extensively utilized to make liners. Even so, large manganese steel processing EPT calls for substantial value and large cost. For grinding , the affect resistance of liner is not high, and other alloy solid iron with use-resistant and less expensive alloy can be selected. The defect of the metallic liner is that it is not convenient for processing and forming, the high quality is huge and it is not simple to put in and disassemble.

The geometry and configuration of the liner have a direct impact on the production efficiency of the mill. Consequently , there are a number of distinct styles of liners to meet up with the wants in different scenarios. In EPTT, it can be divided into two sorts of liner, smooth and unsmooth.

The clean liner is suited for fine grinding since of the greater sliding of the steel ball and robust grinding and stripping. The unsmooth liner can provide the metal ball to the higher place, have the increased impact force, and have the robust agitation to the steel ball and the ore, so it is appropriate for the coarse grinding. The EPTT strip liner has the rewards of straightforward manufacturing, no or much less screw fixation, compression only with end protect liner or wedge layering, convenient set up and so on, which can also reduce the leakage of slurry aEPTT the screw gap and enhance the power of the cylinder. In addition, angular spiral liner has been deveXiHu (West EPT) Dis.Hu (West EPT) Dis.ed and adopted at home and overseas.

The rubber liner is normally a flat convex tree plate with an approXiHu (West EPT) Dis.mate rectangle, which is usually manufactured up of a K or B condition with a cylindrical bar (i.e., a lifting liner). EPTTnine firm can provide numerous kinds, specs and use of rubber liner, and the top quality is outstanding. It has been popularized in numerous factories and EPTs, and the use effect is extremely very good.

The thickness of the steel liner is EPTTly fifty-150mm, and the thickness of the rubber liner is EPTTly 40-80mm. The service existence of the previous is EPTTly 6 months to 1 many years, and the latter can be up to three several years.

In current a long time, the deveXiHu (West EPT) Dis.Hu (West EPT) Dis.ment of magnetic liner is fast, its performance is increasing, and it is steadily popularizing and implementing. The magnetic liners of ball mills are manufactured of rubber or steel wrapped everlasting magnetic supplies, so they are divided into two types: steel magnetic liners and rubber magnetic liners. EPTic liners can adsorb a layer of ferromagnetic material on the surface area by magnetic pressure, so that materials and media can not straight get in touch with with the lining surface area throughout the functioning process, so as to minimize lining dress in. At the same time, it can also be adsorbed on the wall of ball mill, and it is not fastened with bolts. As the magnetic liner is lighter and thinner than the manganese metal liner, it also has the impact of conserving strength and bettering the output. Simply because the granularity of first stage ball mill is huge, the effect pressure is excellent, and the use is significant, so the magnetic liner is EPTTly only suited for the next phase ball mill.

2)EPT medium of ball mill

The grinding medium is crucial for the ball mill, and the usage is quite large. It was all spherical, and then the casting and baseball media appeared. The diameter of the ball medium is about 15-125mm, and the diameter of the casting EPT is about eight-30mm, and the size is about 8-40mm. Steel balls can be created by forging, rolling and casting. Steel ball is divided into carbon steel ball and alloy steel ball. According to the articles of carbon and alloy components, there are substantial, medium and lower carbon metal balls and substantial, medium and reduced alloy metal balls. The ball is divided into normal solid iron, alloy solid iron and organic multi element lower alloy cast iron ball. Following the metal ball is produced, it can be further treated by warmth therapy to increase its put on resistance. EPTTly, diverse dimensions and various sorts of grinding balls must be picked in accordance to various particular scenarios, so as to accomplish the best grinding result and get the best financial positive aspects.
