Ball Mill

Ball mill is a crucial equipment for the material to be milled after crushing. widely used in cement, silicate products, new construction material, fireresisting material, fertilizer, ferrous and nonferrous metel processing, and glass ceramics ,etc, It is mainly used to mill all kinds of materials with or without water

Ball Mill  Working Theory

Dived by external gear,this ball mill is horizontally tubular running type device with two cavities. The raw material enters spirally and evenly into the first cavity through input middle hollow axle. In this part, there are ladder or ripple plates, as well as different types of steel ball. Formed during cylinder rotating,the centrifugal force brings those balls into a certain height. And consequently the materail is stricked and grinded. After that, the material enters through single layer plate into the second cavity for the further grinding, which had been embedded with flat plate and steel balls. In the end, the powder is discharged by output grate plate and the milling function have been realized.

Ball Mill Structure Characteristic
This machine is made up of feeding part, discharging part, gyre part, transmission part, (decelerator, small transmission gear, generator, electrical control ) and so on.  With casting steel fot the middle hollow axle, replacable lining, casting rolling gear for the rotating big gear embedded werable plates in the cylinder, the ball mill shows the characteristic of bearing well with wearing, running steadily and woking reliably.

the classification of grinding mill

1.Ball Mill

Ball MillThe ball mill  is a key equipment to grind the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc, and the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.

2.LM Vertical Roller Mill

LM-series vertical roller mill is one advanced mill, adopting top technology domesic and abroad, and based on many years mill experiences. It can crush, dry, grind, and classify the materials.

Raymond MillFrom the shape look like a steel container to erect , with inlet , outlet and central parts of the feed port . MPS mill shape and some approximation . Raymond mill  stick rotation axis is vertical , MPS mill grinding stick rotation axis is the approximate level . Within the lower part of a motor driven mill grinding mill rotation will need to stick with the grinding material crushing or grinding through the air inlet of the wind blowing finished materials , mill within the upper part of separator can be separated coarse and fine powder , and then passed through the mill The wind machine out of the outlet from the collection

5.coal mill

coal mill must be crushed before grinding. The crushing plant common includes Vibrating feeder as feeding material to Jaw crusher, which is as primary Jaw crusher. If need secondary crusher, Cone crusher or Impact crusher can be used. After primary crushing, the coal can be feeding to Ball mill to fine grinding. To increase Ball mill effective, the vertical coal mill or coarse powder mill can be setted before Ball mill as pre-grinding.

Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other end. Large to medium-sized ball mill  are mechanically rotated on their axis, but small ones normally consist of a cylindrical capped container that sits on two drive shafts (pulleys and belts are used to transmit rotary motion). A rock tumbler functions on the same principle. Ball mills are also used in pyrotechnics and the manufacture of black powder, but cannot be used in the preparation of some pyrotechnic mixtures such as flash powder because of their sensitivity to impact. High-quality ball mills are potentially expensive and can grind mixture particles to as small as 5 nm, enormously increasing surface area and reaction rates.
The Ball Millis a horizontal rotary drum apparatus driving by gears outside. It is a lattice pattern with two storage cells. The raw materials enter into the first cell of the Ball Millevenly through the quill shaft in charging part.

vertical roller mill

Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine comes with roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the level of circular movement imposed by external grinding roller in the vertical pressure on the disc on the material being the joint action of compression and shear, and to crush.
Material grinding process: motor through reducer rotating drive disc, the material falls from the mill under the central entrance and exit, under the action of centrifugal force to the disc edge by the roller to move and the crushing, grinding out lap after the material was speed up the flow to and vertical mill with one of the separator, after the meal by the separator back to the mill, the re-grinding; powder while grinding out with air, dust collection equipment in the system to collect down, that is, products . Established through the mill in the pneumatic conveying of materials, a larger air flow rate, which can use waste heat of gas, at the same time dry grinding operations.

Vertical Roller Mill Principle:
Used in cement grinding production grinding parts of its various forms, there is a cylinder, cone type, ball type, etc., and roller surface is also flat, curved, convex round noodles. Applied to the grinding roller to roller grinding along the track bed in close contact with the material strength of a spring pressure, hydraulic, etc..

How Vertical Roller Mill Works:
It has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. There are two circular disc slot, and roller to the tire shape, work pressure in the tank. Disc roller and the relative sliding velocity between small and roller can swing, even if the roller sleeve and the disc after the liner wear can guarantee a good abrasive, will not affect the grinding effect. Roller symmetrical structure, one side can be upside down after use and wear.
Material grinding process: hydraulic pneumatic roller device through the pressure applied to the material on the crushing of materials, the materials have been moved to crush the edge of disc, from the disc around the nozzle from the exhaust air to improve these materials to Separator.Meal to separate returns after a concentrated mill, fine powder was collected in the precipitator unloading. In the gas flow is small, the meal can not be increased to enhance air flow, they would fall through the nozzle discharged outside the mill, bucket elevator to be transported to the feeder of vertical roller mill, and was re-grinding mill feed people. This cycle features of the way there:
① ring by adjusting the air valve, can change the product fineness can Shide mill bed load material uniformity and stability, improving the grinding efficiency;
② coarse particles in the external circulation, helps reduce Fan power consumption and overall system power
