Classifications of Feed Pellet Mill
Pellet mill equipment can be classified into three categories according to working principle of forming part: Pressing, Extrusion and Stamping
1. Pressing: formed by compression effect between pressure rollers with the opposite direction , same speed and hole .
2. Extrusion : the pressure roller presses the conditioned materials out of die by frictional resistance to materials from pressing die
3. Stamping : Using the reciprocating linear motion of the piston to press the material into certain shape
commonly used types of pelletizer in the feed industry can be divided into pistons pelletizer, auger-type pelletizer, ring die pellet machine, flat die feed pellet machine and so on according to the structure features of pressed parts
The Basic Demands of Feed Pellets Production
The pellet feed are often short strip and the pellet diameter is set by the size of animals and poultry. Generally the range of baby animal feed pellet is about 0.5-2.5mm and the length is longer than the diameter by 1-2 times. Depending on the physical shape of the processing and the finished product, the pellet feed can be classified into soft pellet feed produced by pellet feed processing equipment , hard pellet feed and 135 extruded pellet feed by extruder. The following is the requirements for hard pellet feed:

2.
3.
Stability in water for shrimp and eel pellet feed is required(loss ratio). the method is putting them in the net, soaking about two hours , fetching out, drying with drier and then measuring the loss percentage. Shrimp pellets loss rate is less than 12%; pellet feed for eel should be less than 4%. The general stability in the water of more than 15 minutes is allowed.The pellet feed are often short strip, and the pellet diameter is set by the size of the feeding fish and shrimp. Generally the rang of it: fish feed is about 0.5-2.5mm and the length is longer than the diameter by 1-2 times. Depending on the physical shape of the processing and the finished.

Tips: Well and evenly mix these feed stocks with water and feed the rabbit regularly, and also feed the rabbit with green forage, making the rabbits choose the feed that want freely.
