This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

Sluices are usually used in alluvial, eluvial, and colluvial ores but many artisanal operations concentrate gold from primary ore ground in hammer mills or Chilean mills. An ore pulp usually with 1020% (in mass) of solids is pumped to the sluices and gold and heavy minerals sink to the bottom of the box allowing the lighter particles to pass ...

Typical moisture loss through a hammermill when fine grinding for aquaculture feeds is ½ to 2%. Hammermills are generally less expensive to install and operate than pulverizers, typically costing between 250 and 350 per HP for a complete system including the hammermill, feeder, and appropriate air assist system.

II. WORKING OF HAMMER MILL MACHINE When feed is delivered to the hammer mill crusher, it is prepared for cyclone furnace firing by being crushed into 1/4 inch or smaller size feed. Feed enters from the top and is violently thrown against the breaker blocks by the hammers. The final crushing is done between the hammer faces and the screen bars.
