The match of Middle Chrome Mill Linings and High Chrome Cast Balls has been the typical model in coal mills and cement mills. Pearlitic Chromium-Molybdenum Alloy Steel Series: The Pearlitic Chromium Molybdenum Alloy Steel Liners are widely used in AG Mill,SAG Mill and Ball Mills. Hardness: HB310-375 (equivalent to HRC33-42)

Most mills can be converted from metal liners to composite rubber liners. These liners combine the best characteristics of metal alloys and rubber to obtain a superior design for use in AG/SAG, grate discharge, overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates

The robotic system is composed mainly of a robotic manipulator of at least 5 degrees of freedom, and a gripping mechanism which allows, in a sequential and programmed way, to take, manipulate and...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Grinding with Forged Steel or Cast Balls? Are you are looking for grinding efficiency or grinding costs? Grinding efficiency: as a first estimate, I would tend to say no major difference if you ad the same ball sizes (to control mill power draw). Grinding costs: very much depends on the milling conditions. Main parameters are corrosion (ie iron ore), impact (ie grate …

I assume you are referring to a ball mill, since cyclone discharge recycle normally goes back to ball mill feed. I am less versed in ball mill grinding. Ball mills break rock by compression fracture, while SAG mills predominantly break by shear. Some compression fracture does occur, but, it is not the major comminution mechanism.

With grate discharge mills – typically SAG, AG and ball mills – the conventional relining process at the discharge end usually involves removing the dischargers and grates, replacing with new lined versions and hammering in large, long bolts through the …

"In recent years, the trend to smaller top-size ore feed into SAG mills has been matched by a trend toward smaller but more balls in the SAG mill charge. High ball-to-rock ratios and low overall mill charge levels are now widely used. These practices can result in periodic loss of rock charge and ball-on-liner damage," said Royston.
