MMR Roller Mill. MMR mill is high-end products, leading the future market. The contact part of material is made of food-grade 304 stainless steel, no dead angle, no residue; Easy to flip the feeding unit, easy to clean the feeding area; The grinding roller unit, a spin off from the grinding body assembly, convenient operation reducing paring time;
The roller torques are managed by the load share factor (Klf). If Klf = 1, identical torque is delivered by both rollers. For values of Klf < 1 the fixed roller delivers more torque than the movable roller. For values of Klf > 1 the movable roller delivers more torque than the fixed roller. Klf can be varied in fine steps.
Working principle: The main unit of vertical mill is driven by decelerator, then take the grinding plate's rotation, grinding rollers follow grinding plate for the friction, materials pass the feeder valve, first feeder conveyor, second feeder conveyor to the grinding plate's center, with the centrifugal force, materials move to the edge of grinding plate, when reach the grinding track ...

The grinding table – and thus the grinding rollers – of the QMR² mill are set in motion by a motor with a gear unit. The rotating grinding rollers are pressed onto the bed of material by means of a hydraulic cylinder. As the grinding table rotates faster than the grinding rollers, it presses the material under the roller.
for the mills when starting up with a filled grinding track. • The rollers are connected in pairs to a common hydraulic unit (except in the case of 3-roller mills). • An almost parallel grinding gap is maintained between the grinding rollers and the grinding plates during the entire ser-vice life of the grinding parts.
In the vertical roller mill which is widely used in the raw material grinding process, raw materials input grinding table are crushed and pulverized on it and transported to separator by kiln exit gas introduced into the mill as drying, transporting and separating purpose.
Since 1982, Normac has manufactured the Formaster, a CNC grinding wheel dresser, to satisfy two requirements: sophisticated wheel dressing for our own machines and that of the grinding industry at large.

1:40 or 50 (depending upon the grinding wheel) and is used for grinding the following materials. oCast iron or hardened steel oSoft steel oConnected carbide tools (using silicon wheel) In India we use IOC Servocut oils as cutting fluid. There is a special grade oil manufactured by IOC for grinding alone. It is called Servocut - clear.
Grinding roller - Contact roller A perfect surface finish and ideal deburring are achieved in a single operating sequence. The grinding pressure is generated by positioning the roller downwards below the zero level. When the roller approaches the workpieces, the rubber coating of the roller under the abrasive belt is pushed inwards.
