A series Feed Mill Grinder Introduction. Feed hammer mill is a necessary equipment in animal feed pellet plant.We supply three types of feed hammer mills, this one is called common feed hammer mill mainly used for grinding grain products that are to be made into livestock feed pellets or poultry feed pellets.
Mill housing is fully lined with replaceable liner plates. Final required product size is defined by feed rate, rotor speed and aperture size of bar grids. The mill can also be designed to accommodate heavy-duty perforated plate screens or fine stainless steel wedge wire screens for much finer products.

Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding. Ball mills use an established technology and offer certain advantages. However, they have higher energy demands. By using an appropriate kind of the more efficient roller mill technologies – either as a replacement or in combination with ball mills – considerable energy savings can be ...
Hammer mills are more energy-efcient in producing fne particles than knife mills (Liu et al., 2016a; Miao et al., 2011) and are appropriate for producing fne particles (Liu et al., 2016a). Also, the relationship be-tween particle size change and energy consumption was described by a number of comminution laws (Charles, 1957).
GD Hammer Mill Process The GD hammer mill is designed for the animal feed industry, to grind raw materials into small particles and meal. The hammer mill range covers capacities ranging from 10 100 tons per hour, dependent on type of raw material, formula and required grinding structure. The hammer mill can be incorporated in both a pre ...
