Grinding Media

Description features:Many minerals used in manufacturing processes need to be finely ground before they can be utilised in the preparation of the final product.
Whitfield and Son Ltd offer a wide range of grinding media to enable cost effective reduction of the particle size of the materials.
High Density Alumina
A high aluimina 90% + Al2O3 (Alugrind) is isostatically pressed and sintered at high temperature to give a finished produc. Alugrind 90 has a density in excess of 3. 57gm / cm3 and is completely gas-tight. Isostatic pressing ensures that the density and hardness of the product is the same from the outside surface to the centre of the media and this ensures extremely low and uniform wear rates. High denisty alumina media is used to grind material where contamination must be kept to an absolute minimum, but because ofthe very high efficiency of Alugrind 90 + it SI fining increasing use in the productio of numerous materials from ceramic raw materials to colours, glazes and technical ceramics.
Silica Pebbles
Silica Pebbles are the traditional grinding media for all general purpose grinding of bulk materials such as silica and feldspar. Our supplies are selected from the natural pebble deposits in Southern England and Northern Fance.
Glass Beads
Glass Beads of 3 types are available:
GJ-I General type for normal grinding situations.
GJ-II Strengthening type which exhibits good hardness and wear resistance.
GJ-III Wear resisting type with higher density, superior wear resistance even in high intensity grinding.
YTZ Zirconia Grinding Media
YTZ ceramic media features high density and super hardness which enables the user to achieve superior grinding efficiency. The high wear resistance YTZ ceramic media effectively eliminates product contamination and other problems associated with the use of lower quality grinding media, which may be prone to chemical attack or shor mill life.
Zirconium Silicate Beads
We have available Zirconium Silicate beads made by a fusion process giving a fine crystalline stucture. This material can be used in the grinding of coatings, inks dye stuffs, pesticides, cosmetics, titanium dioxide, magnetic materialsz and numerous other minerals.
We also supply Kaolin beads, alumina silicate beads etc
