The SRL.XT has proven to have superior wear life compared to hard metal pumps and conventional rubber lined pumps The replaceahe rubber liners are significantly less eipensive than hard metal so. mill operating costs can be dramatically reduced

We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.

around the secondary crusher, a reduction in SAG mill make-up media size to 105 mm (and increased ball charge), a reduction in SAG discharge screen size to 8 mm and smaller, 65 mm ball mill make-up media instead of the 80/65 mm blend. The smaller SAG mill media size was recommended due to the wide range of conditions the mill

• The of a ball mill can either be grate discharge (low level) or simple overflow trunnion discharge. • Grate discharge mills are fitted with discharge grates between the cylindrical mill body and the discharge trunnion. • The pulp flows freely through the openings in the grate and is then lifted up to the level of the discharge trunnion.

Mill SHELL Liner & HEAD Liners. Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.

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.

effective discharge of pulp/slurry from the mill is the key objective of the pulp lifter design. The modelling showed high wear zones at the pulp lifter discharge outlet. In the incumbent design, with the rotation of the mill, slurry was not being discharged effectively and the aggressive recirculation was causing localised wear.
