apr 01, 2017· pilot plant test results with various ores showed that low energy consumption feature of vertical roller mills is applicable to the ore industry. grinding test results for zinc ore showed that it is possible to decrease the total grinding energy consumption from 20.11 to 11.40 kw h/t by using vertical roller mill instead of ag
highly productive rolling can be carried out by setting up as many rolling mills (2hi mills or universal rolling mills) in a straight line as there are rolling passes for non-reversible rolling. it is a method that is often applied for rolling small to medium-sized shaped steel.the predominant style is the stand-exchanging method through which the roll is exchanged in its stand.

modern wire rod mills are high speed mills capable of rolling of smaller dimensions at high production rates, while at the same time keeping investments and operating costs at the reasonable levels. as a rule, wire rod mills are designed for an annual output of between 300,000 t and over 800,000 t (two strand mills).
hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. it produces size reduction by impact. the materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer) which rotates at high speed inside the chamber.
