Charge behaviour and power consumption in ball mills: sensitivity to mill operating conditions, liner geometry and charge composition. Author links open overlay panel ... the effects of changes in mill operating parameters and particle properties on the charge shape and power draw of a 5-m ball mill. Specifically, changes in charge fill level
[email protected]Aug 26, 2017 Reagent to Help Reduce Steel Consumption. Composite Materials for Ball Mill Liners. Rubber Liners. The fact that over 25% of the original weight of steel liners and balls is discarded as waste is probably one of the factors that has not been considered often. This is particularly true for mill liners, “Mill liners are finished metal products
Get PriceApr 22, 2017 Ball Mill Liner Consumption Average consumption of shell liners, for both chrome and manganese steel, is 1/3-lb. per ton of ore crushed. The consumption of lining seems to be fairly constant regardless of the hardness of the ore, fineness of product, or other conditions
Get PriceP.W. Cleary [10] is a pioneer in the study of the mineral industry using DEM. M.S. Powell et al. qualitatively analyzed the changes in the shape of the ball mill liner over working time through
Get PriceJan 05, 2016 Optimize Ball Mill Liner Replacement. Shell liners may be furnished of various materials and of several designs. In each case the material used is the best obtainable, resulting in the lowest cost per ton of ore ground. ... it is claimed, leads to a greater power consumption and to improved grinding. Furthermore it would appear that the studs
Get PriceSAG mill liner change-out life/cycle vs. tons/kg consumed. Ball mill liner efficiency based on liner geometry and its influence on kW-hours/ton, total tons/life cycle, and P80 transfer to cyclones. Ball mill grind is based on different principle; it has some attributes similar to SAG mill optimization
Get PriceJul 05, 2017 Table No. 8 summarises the liner and media consumption for both mills. Total liner consumption in Mill I was 0.0953 vs 0.0898 kg/tonne (0.1906 vs 0.1796 lbs/ton) in Mill II. Total media consumption in Mill I was 0.8635 vs 0.7540 kg/tonne (1.727 vs 1.508 lbs/ton) in Mill II. Mill II thus shows a 6% lower liner consumption and a 15% lower media
Get PriceMar 26, 2021 Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closed-circuit grinding and feed rate. (Ball mill) To improve the ball mill grinding efficiency, you must first understand the factors that
Get PriceJun 17, 2021 The mill performance is analyzed using three parameters: useful power, percentage of useful energy consumption and tangential cumulative contact energy. In this paper, a new method for parameter design and optimization of trapezoidal liner is proposed based on

Get Price（2）Light weight, thin thickness, energy saving and electricity saving. The thickness of magnetic liner is very thin. It is about 40-50% of high manganese steel liner. It can effectively reduce the load of ball mill, reduce the consumption of ball mill and increase the volume of ball mill. （3）Noise is low, drop ball consumption

Get PriceJan 11, 2020 The liner made of ordinary material is too thick, which will reduce the effective volume of the ball mill cylinder. Besides, thick liners increase power consumption due to the large weight and reduce the production efficiency of the ball mill
Get PriceDec 13, 2018 The ball load behaviour in a pilot mill is studied under conditions of increasing particle filling, for coarse silica feed (0.8–1.8 mm) and fine silica feed (0.075–0.3 mm), at the mill speeds
Get Priceoperating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree
Get PriceMay 19, 2020 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
