  • Roller Mills Amp Roll Crushers 1200 Series Cpm

    Roskamp Roll Crushers are designed for the most demanding crushing applications, with roll corrugations and roll speed differential ratios available to match any operating conditions. Available in two-, four- and six-roll designs, the 1200 Series has a 12 roll diameter and a range of 30 to 225 HP.Roskamp Roll Crushers are designed for the most demanding crushing applications, with roll corrugations and roll speed differential ratios available to match any operating conditions. Available in two-, four- and six-roll designs, the 1200 Series has a 12 roll diameter and a range of 30 to 225 HP.called the roll speed ratio or roll speed differential. For instance, if one roll rotates at 1,000 rpm and the other at 500 rpm, the roll speed ratio is 21 1,000500. More shear and thus a larger roll speed ratio is required to crush less friable particles.For roller mill grinding, roll gap was the most significant factor affecting energy requirement, followed by the roll speed differential. For hammer mill grinding, screen opening size had the most significant effect. For both mills, feed rate was not significant and energy efficiencies were about the same.

    This results in a differential in speed between the roll pair. Typical differentials range from 1.21 to 2.01 fast to slow. Typical roll speeds would be 1,300 feet per minute 395 mmin for a 9-inch 23 cm roll to 3,140 feet per minute 957 mmin for a 12-inch 30.5 cm roll.This results in a differential in speed between the roll pair.

Roll speed differentials simply means one roll turning faster than the other and is usually described in the form of a ratio, slow roll speed expressed as 1. For example, rolls operating at 1.51 differential with a fast roll speed of 1,000 RPM would have the slow roll turning 667 RPM.Jan 09, 2012 Jan 09, 2012 Msec with roll speed differentials.

For example, rolls operating at 1.51 differential with a fast roll speed of 1,000 RPM would have the slow roll turning 667 RPM.The use of HTD belt drives to achieve differential roll speeds of up to 2.51 is now well proven, and as a result of such engineering technology there is little need for lubrication of the modern roller mill.A roller mill is a milling machine that gently and gradually reduces material to a smaller size. There are one or two pair of chilled cast iron rolls inside the machine. These rolls are lying parallel and are supported at each end by roller bearings. The back roll is in a fixed position and the front roll is movable to adjust the roll clearance .
