Industrial Grinder capped 50 for materials? : playark
50 materials max and only 25% of required materials. That means that 1) it's pointless to put structures in there because just placing the structure and destroying it nets 50% of materials (IIRC), and 2) unless you have insane amounts of spare saddles and armor sitting around, you'd probably never recoup the cost of building the thing by just grinding stuff.

Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most size-reduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.

A pilot-scale grinding technology of ceramic medium stirred mill was proposed in this study. Based on the specific productivity and grinding efficiency, the appropriate grinding parameters were ascertained as follows: material ball ratio of 0.7, ceramic ball medium size ratio (10 mm: 15 mm: 20 mm = 3:2:5), stirring speed of 110 rpm, grinding concentration of 50%, and medium filling rate of 90%.
11.31 Abrasives Manufacturing
and close sizing of either natural or synthetic abrasives. Raw abrasive materials first are crushed by primary crushers and are then reduced by jaw crushers to manageable size, approximately 19 millimeters (mm) (0.75 inches [in]). Final crushing is usually accomplished with roll crushers that break up the small pieces into a usable range of sizes.
Back to Basics Hammer Milling and Jet Milling Fundamentals
feed stream in hammer mills for grinding tough materials. However, liquid nitrogen is seldom used in jet milling opera-tions due to the swift heat exchange between the material and the grinding gas. The grinding gas heats up the super-cooled feed stream, and the material loses its brittleness when it absorbs this heat. Stickiness.

Milling may also be used to reduce all the particles in a material to a given size or smaller. Because grinding is selective (larger particles receive more force than smaller particles), size reduction tends to proceed to a given size and then slow down, making it possible to obtain a reasonably tight size distribution. Size Classification ...
