How a Grate Discharge Ball Mill Works
Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape.
IMPROVING ENERGY EFFICIENCY VIA OPTIMIZED …
ore entering through the feed port is ground by this field and, after being sufficiently ground to the grate slot size, the slurry leaves through the slots in the grate. The field of breakage influences the rock mass in the SAG mill. Should the incoming ore be harder and the field of breakage insufficient to reduce the size, the ore stays in

The grate shall be ½ - #13 galvanized steel or ½ - #13 304 stainless steel per ASTM F1267. Alternatively, aluminum slot grate may be left open top. The grate shall have diamond-shaped openings with a 52% open area and be ADA compliant. The flange at the bottom of the aluminum slot grate frame shall be riveted to the pipe with a minimum of two
SAG Mill Liner Design
Grate design should incorporate an integral radial lifter. This lift on a grate can increase the grate life by up to 50 percent. The slot opening size is determined by the lump size to be retained in the mill. Grate plugging is minimized by proper slot taper and alloy selection. See Figure 5.

10 Types of Graters | Popular Grater Types
Graters come in small sizes for the home kitchens and large sizes for commercial kitchens. The size of a grater impacts the final outcome of the food. For example, small size graters such as zesters range in size close to 15 x 2.13 x 1.42 inches. Medium size grater are around 11.75 x 0.75 x 3.5 inches.
