We have XRP 783/803 coal mills in our power plant. Those mills are fitted with rotary air vane. Presently we have overhauled 8 mills and converted those into HPMS system where sinter cast inserted grinding elements are in use. Also vanes fitted in rotary air vane segments are backward curved with an angle 45 deg in respect to direction of rotation.


High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.


Within the mill roll division we also produce replacement hardened steel rolls for the cattle feed industry. The second division is the kernel processor division and it was created in 1999 and this division specializes in kernel processors for self-propelled forage harvesters. We work with large OEMs, distributors and dealers worldwide.
