The model shall enable the prediction of the throughput, the particle size distributions around the verticalrollermill circuit, the specific energy consumption and in a later stage the wear to be expected in dependency of ore treated. The model combines performance data from pilot and industrial plants with mineral characterization methods.
Due to the compact design and material transportation system of vertical roller mills (VRM), some important streams (total mill feed and discharge, dynamic separator feed and reject) remain in the

roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC 70oC with strip recoil temperatures and interstand strip temperature rarely exceeding 160 oC depending on product. Roll Bite temperatures in slower heavily drafted stands can peak in the region of 300oC, diminishing with the
Problems concerning reduction of the dynamic loads on the horizontal and vertical rolls of universal rollingmill stands are examined. The unacceptably large shock loads that develop in the
The vertical roll mill usually consists of several generator sets composed of rolling mill and a series of auxiliary machines. In general, the equipment that causes plastic deformation of rolled pieces is called rolling mill. Vertical rolling mill is usually composed of sound card stand, press down system software, gear transmission, vertical

Specialty Polymers & Polymer Processing. James L. White, Kyonsuku Min, in Comprehensive Polymer Science and Supplements, 1989 9.3.2 Tworoll Mills. The tworoll mill was used in industrial operations of various types well into the dimmest past.It was, however, only with the 1836 patent of Chaffee 31 that roll mills began to be used in the
Feeders for Vertical Roller Mills. Williams industrial roller mills are used for a wide range of applications and materials, which means that the proper feeder selection is essential for highcapacity, troublefree operation and more efficient production. You can customize your vertical roller mill depending on what material you need reduced.
When a mill has to produce billets of different sizes the gap between working rolls of the millstand must be adjustable. To ble to reduce the thickness of the metal gradually the motors of consecutive millstands must have differing speeds. This requires that the motor must be capable of speed control in the range 1.5:2.

Both multiblade and sail type mills run at speeds of 60 to 80 rpm. The propeller type has two or three aerofoil blades and runs at a speed of 300 to 400 rpm. These rotors have to face the direction of the wind in order to generate wind power. The fourblade type rotor is shown in the figure. This motor runs at low speed in the range of 100 to
