If I have a ball mill 6x12, I wish to get better energy consumption, then It is possible to get when I change the trunnion bearing by roller bearing for mill grinding application? If it is possible, which is the percentage (%) to save from the actual power consumption? Thanks & Best regards
Jun 21, 2019 The Vertimill product line features standard mill sizes from 11kW (15hp) to 3352kW (4,500hp) and can handle feed sizes up to 6mm and grinding products smaller than 20 m.
Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills
between the ball-mill power draw values determined from the Denver slide rule, and those calculated from the proposed model. zFrom the distribution of the points around the line of comparison the good agreement of the results received is obvious. 0 200 400 600 Ball mill power draw predicted from the Denver slide rule, kW 0 200 400 600
grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to 100% of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded upon which milling energy consumption
The cement industry, as a traditional high power consumption industry, power consumption in the cement grinding process takes a large ratio in the whole production, electric power consumption is about 60%-70% of the total consumption. With more and more strict Energy conservation and environmental protection policy published, excess production capacity, and severe market competition, energy …

The aim of this study was to determine the effect of main milling variables on power requirements and energy consumption of laboratory ball mill refiner for chocolate.It is consisted of vertical cylinder, equipped with a rotating shaft with arms, and filled with steel balls as a grinding medium.
Its electricity consumption is lower than that of ball grinding mill of the same level by over 60%. VANGUARD adopts the high-efficiency impeller energy-saving fan and the working efficiency of which can reach 85% or above while traditional grinding mills equipped with straight blade fan can reach only 62% of air inducing efficiency.
The high power intensity results in a small mill with short residence times – less than a minute – which avoids overgrinding. This, together with the 8 consecutive stages of grinding and product separator, produces a sharp size distribution without external classification.
contributed to an increased rate of production and reduced specific power consumption in the grinding operation and wear rates. Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of
