Suggestions of energy saving for vrm grinding roller manufacturer with the continuous advancement of energy conservation and emission reduction in china, the foundry industry is the first to bear the brunt of high energy consumption and high pollution. as a well-known steel casting manufacturer in china, chaeng can provide customers with large-scale customized steel castings, such as the ball mill.
The industry best in energy-efficient grinding, the ok mill uses five to ten percent less power than other vertical roller mills and 30 to 50 percent less energy than conventional ball mills. easy operation and maintenance. worn roller grinding surfaces can either be replaced or re-welded inside the vertical roller.
The vertical roller mill has been widely used and promoted in the electric power, metallurgy, chemical industry, non-metal industry because the overall efficiency attributed to energy-saving and low consumption is becoming more and more evident in the cement industry. grm series vertical roller mill is developed with the features of high efficiency, energy-saving and environmental protection which.
The vertical roller mill has high energy efficiency and the installation space is smaller compared with tube mills. these days, the vertical roller mills have been widely adopted. a）structure (1) the rollers are hydraulically pressed against a disc table and the feed is.
Vertical roller mills (vrm) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. this and further arguments led to the increased share of vrm for the grinding of finished cement. taking into account that vrm usually have a bigger output than ball mills, it can be declared that the major part of the cement production with newly installed mills comes from.
Vertical roller mills for finish grindingcosts & benefits. energy savings enabled by replacing ball mills with vrms can be 20 to 30% and is primarily a function of the product fineness. electricity consumption can be reduced by 10-24 kwh/ton of cement. savings in the range of 20-24 kwh/t clinker are reported from india, depending on clinker.
