A grinder-mixer is a type of agricultural machine used to process livestock feed from grain. It is a portable mill that combines the mixing and grinding operations. Grinding of ingredients generally improves feed digestibility , acceptability, mixing properties and pelletability .
The energy needed for mixing comes from a loss in pressure as fluids flow through the static mixer. [2] One design of static mixer is the plate-type mixer and another common device type consists of mixer elements contained in a cylindrical (tube) or squared housing. Mixer size can vary from about 6 mm to 6 meters diameter.
Meat grinder blades rotate at a much slower speed than blade grinders, which may rotate at speeds as high as 20,000 to 30,000 rpm; for example, the Steele model mixer-grinder by Indian appliance manufacturer Preethi has a no-load speed of 23,500 rpm and loaded speed of 11,500rpm. [3]
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%. [9] [10] The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [11]
The mixer plays a vital role in the feed production process, with efficient mixing being the key to good feed production. If feed is not mixed properly, ingredients and nutrients will not be properly distributed when it comes time to extrude and pelletize the feed, or if the feed is to be used as mash.
