Single-compartment mills are of a similar design to air-swept mills, but the material is discharged mechanically by a discharge diaphragm. These mills are well-suited for finer feed materials. They are used for secondary grinding downstream of a primary grinding unit or in a combi-grinding system with a polycom ® high-pressure grinding roll.

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42'' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

Liner wear in primary mills is reported to be greater than the wear on crushing surfaces and mill liners in a crushing and grinding circuit. Overall savings in steel consumed are estimated to be 55% to 60% of the cost of rod and sometimes ball wear. Savings in semi-autogenous milling should be less due to ball wear and increased liner wear.

Ball Mill Operation. Ball mills ride on steel tires or supported on 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 synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

Posted by. u/BradleyPutters. 3 days ago. I’ve wanted to make a coral-themed putter for a while now, and always thought I would 3D print molds for the coral designs. Turns out that’s mostly impossible, so I used a dremel and hand-carved the pieces instead from acrylic. The alignment line is real coral.
