Whereas the slide shoe supported or shell supported mill is relatively young. However, there are many advantages over trunnion mounted mills with slide shoe / slipper pad bearings. The main issue (to my mind) is the relatively conservative nature of the mining industry - it is more a "if it isn't broken don't fix it" mentality.

the mill support bearing and shell structural design. • Reduced maintenance – The low-profile T-track system eliminates the need for frequent inspections, repair and bolt tightening. Vulco ® rubber conforms to the mill's internal surface, creating a seal that prevents leakage, slurry erosion of the mill shell and precious metal lockup

Shell-supported ball mills are becoming the mills of choice over those with trunnion bearings. Depending on the size of the mill, there are two, four or six sliding shoes per bearing assembly. The expected bearing load determines whether hydrostatically or hydrodynamically lubricated bearing shoes are used. Sturdy and reliable: mill bearing ...

The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The only way to eliminate the problem of flow-back and carry-over of slurry and pebbles is by optimizing the design of the discharge arrangement.

Mill shell thicknesses increased and the head and discharge walls of trunnion supported mills became massive. The question as to whether or not energy was being effectively transmitted to the material being ground as the layers of balls increased in the grinding chamber remained unanswered.

Ball Mill System. Compact and efficient! KHD Humboldt Wedag mills are space-saving, compact, high on performance and low on maintenance. This is primarily due to the support bearing design and the mill drive used. The mill is shell-supported, mounted on slide shoe bearings at both ends and made completely as a welded design.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

When ball mills are supported on individual bearing jewels via races or surfaces on the mill shell, this is referred to as a slide shoe bearing. This modern bearing is effective and inexpensive because the head linings of the mill do not have to be designed to carry the load. Depending on the mill size, two, three or four sliding shoes are used ...

mill internals. Sepro Mill shells are manufactured in one piece to high quality standards and are thermally stress relieved to eliminate localized high stress areas. The machine utilizes the Sepro Pneumatic Tyre Drive System (PTD) which provides an alternative to standard trunnion supported mills. This system of rubber tyres

3. Operation of Tubular Ball Mills. Tubular ball mills ride on steel tyres or are supported at both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronous motors that operate through an air clutch or gear system.

Cement ball mills can be divided according to discharge method: grate ball mills and overflow mills, and can be divided into wet mills and dry mills according to their processing conditions. 【Cement mill structure】 Ball mill is mainly composed of feeding part, supporting frame, rotary part, discharge, transmission, lubricant and cooling part.
