RITEC proposes grinding media for all types of vibratory mills and ball mills.

The hardness of materials is measured according to two scales: the BRINELL scale (noted HB) and the ROCKWELL scale (noted HRC).

The Brinell scale measures the hardness of materials by compressing a ball, usually made of steel, on the material to be tested.

The ROCKWELL scale measures the penetration of the material by a diamond cone (in HRC notation).


Whatever the brand of your mill and your materials to be milled, we have the capacity to supply you with grinding media



Grinding balls

Forged grinding balls with a hardness to suit your application (up to 65 HRC, 780 HB).

Grinding balls with a hardness of 60-65 HRC with high chromium content: 11-13%, 17-19%, 19-21%, 24% or 30%.

Chrome steel grinding balls from 1mm to 150mm

Aluminium oxide grinding balls for iron contamination free grinding


Grinding Bars

Grinding bars suitable for all types of vibrating mills with hardness 19-37 HRC, 280-350 HB

sizes: 16mm, 20mm, 25mm, 30mm, 35mm, 40mm, 50mm and 60-100mm



Cylpebs are used for both dry and wet grinding and can be used on all types of materials, whether they are very hard or soft.

Examples of materials to be ground are: metal carbides, quartz sands up to 100% SiO2, iron, copper, lead, zinc, baryte, spath-fluor, cement, plaster, lime and even cocoa beans.

The cylpebs have a slightly conical shape with rounded edges.

We offer cylpebs in the following sizes:

12 x 12 mm

16 x 16 mm

20 x 20 mm

22 x 22 mm

24 x 24 mm

25 x 25 mm

28 x 28 mm

32 x 32 mm

35 x 35 mm

40 x 40 mm

45 x 45 mm

54 x 54 mm


An additional advantage of Chillard II cylpebs is that its wear resistance is proportionally higher than that of other grinding media.

In the range of 450-550 HB, 46-54 HRC, the wear resistance of these cylpebs corresponds to a resistance of 600 HB, 58 HRC for other grinding media.
