At Polymer Alliance Services, we have grinding mills which are ideal for achieving results with increased surface area, higher bulk density, better dispersion quality, with the power to break down large sheets and pre-process tough materials. Additionally, we are equipped to grind heat sensitive, elastic, and tough materials with equal ease.
The selection of abrasives for the grinding wheels are depends on the material type of the work piece. On grinding wheel specifications abrasives is represented by an alphabetic character. If we consider three basic types of work materials i.e. very hard, hard and soft or medium then for each category different types of abrasives are used.
FRITSCH Planetary Mills: fine grinding of various materials, mixing,, for loss-free grinding down to a final fineness of 100 nm of hard, medium-hard, desired final fineness, the grinding can be performed dry, in suspension or in, To achieve this, the grinding bowl, containing the material to be ground and grinding balls,....
the rate of grinding in the planetary ball mill is known to be about 100 times greater than that in a tumbling ball mill and about 50 times greater than that in a stirred ball mill2). Another result is given in Fig. 3, from which it is seen that even small glass beads with a low density can be used to grind hard materials
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.
Turbo mills are used in a wide variety of applications from fine grinding of all types of soft and medium-hard materials to coating of powders, grind drying and the fiberisation of various products. Advantages. Easy adjustment of the refiner gap from 0.5 to 5 mm through the conical rotor and moveable stator. Ultra-fine powder.
