Agsag mill liners we have supplied rubber pulp lifters for sag mills up to 40 ft in diameter we are pioneers in the design of both radial and curved pulp lifters also design and manufacture rubber polystl grates and discharge systems
Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wearresistant lining plate as the sag mill does not contain grinding medium the abrasion and impact on the equipment are relatively small the feed of the ball mill contains grinding balls
Ball mill a typical type of fine grinder is the ball mill a slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls ball mills normally operate with an approximate ball charge of 30
The sag mill uses lifting plates along the interior of the drum which lift material throughout the rotations causing them to fall onto one another to promote crushing a ball mill has many steel or porcelain balls put in a drum to grind the feed between balls and between the balls
Both the ball mill and the sag mill can process nonmetals ferrous metals nonferrous metals rare metals etc and are divided into dry and wet types to meet the needs of various materials the structure of the ball mill and sag mill is similar in the rotary system the compo
Sag milling extends itself to many applications due to the range of mill sizes available they can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work done by a ball mill sag mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult if not impossible efficiency through
Even though production was dramatically improved the product size of the secondary ball milling was reduced and recovery increased the results in sagmill line 2 are even more dramatic because of segregation on the coarse feed stockpile sagmill 2 receives a higher percentage of coarse material
