step liner for ball mill

The wrong liner design will increase power and steel consumption, as well as reduce the grind and throughput of the mill. Liners not only come in different designs, they are available constructed from different materials. Liners may he built from MANGANESE STEEL for rod mills and ball mills that use bigger than two inch balls.

3.The material is uniformly fed into the first chamber of the mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, and various steel balls are loaded therein. The rotation of the cylinder generates centrifugal force to bring the steel ball to a certain extent. The ...

The mill is normally used for grinding of ores. Lining of the cylinder plays very important role. It protects the mill from abrasions and at the same time it helps in lifting of the material from the bottom of cylinder. The types of lining are (i) smooth liner, (ii) wave liner, (iii) ship lap liner, (iv) step liner, and (v) Osborn liner.

The results show that the sand mill is far superior to the ball mill in terms of grinding efficiency and preparation cost. The sand mill can produce a powder with an average particle size of less than 0.5μm, which is far smaller than the particle size of the product obtained by the ball milling mechanism. Next, we use an experiment to compare ...

The basic structure of both is composed of the main parts such as the feeding part, the discharging part, the rotating part, and the transmission part (reducer, small transmission gear, motor, electric control). ... There is a step liner or a corrugated liner inside the bin, which contains steel balls of different ...

A ball mill for reducing grain size of silica powder resulting from the interaction of the powder with a milling media and the interior of the mill; the ball mill comprising: a cylinder container having interior radial and end surfaces, each of said surfaces being entirely covered with a liner, said liner being made entirely of silicon nitride.

Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Mill HEAD LINERS. Head liners are of the segmental type constructed of Manganese Steel, Chrome molybdenum, or Ni-Hard and are designed to pass easily through the manhole opening or discharge opening in the case of rod mills. For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner ...

We have a Russian customer, who has a cement clinker production line, which includes a Ф 2.2m × 6.5m ball mill. One month after the ball mill was put into operation, the mill liners. and step liner of the first bin was broken frequently. At most, 18 pieces were broken …

Our Double Wave Ball Mill Liners Capability: EB can fabricate the Ball mill liner plates as per your material and your sizes. EB is a professional manufacturer of high-quality ball mill liners, focusing on wear-resistant ball mill liners for 21 years.

Lorain liners consist of high carbon rolled steel plates held in place by manganese or hard alloy steel lifter bars. Ball mill liners may be made of hard cast iron when balls of up to 5 cm in diameter are used, but otherwise cast manganese steel, cast chromium steel, or Ni-hard are used. Efforts to prolong liner life are constantly being made.

Answer (1 of 2): You'll find a number of unique layouts and fashions of ball mill designs. Like milling balls neighbourhood economics and fundamentally managing costs ascertain the great layout and style and stuff to use. The preliminary pair of backpacks is infrequently the last design picked. D...

According to different grinding requirements, ball mill liners are roughly divided into 9 types, which are wedge-shaped, corrugated, flat-convex, flat, stepped, elongated, rudder-shaped, K-shaped ball mill rubber liner and B-shaped ball mill rubber liner. These 9 kinds of grinding mill liners can be classified into two categories: smooth grinding mill liner and unsmooth grinding mill liner.

concavities. The liner shape of MODEL II was step liner as shown in Fig. 1(b). MODEL III (Fig. 1(c)) had wavy shape on step liner. MODEL IV was the trapezoidal liner (Fig. 1(d)). The mill without liner (MODEL O) was also simulated to compare with those mills. The total number of lifters was set constant at 28, and the rotating direction of the ...

The thickness of the liner and the weight increase the power consumption, reduce the effective volume of the cylinder, and reduce the production efficiency of the ball mill. If the magnetic lining plate is selected, the effective volume of the cylinder can be increased, and the weight is relatively reduced, and the power consumption is reduced.

A longer lasting mill liner means less downtime for maintenance or new liner installation. A mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. Safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners.

The liner are almost not affected by the slurry corrosion and wearing, that is, it showed very high worn proof character in the wet type ball mill, which make the lifespan double increase. Usually the liner has 1~2 time higher than the high manganese liner.
