dry roll press pellet mill mainly depends on the manner of external pressure to force the material going through the gap between two relatively turning rollers to compress into laminar particles. during course of roller pressingthe real density of materials can increase 1.5~3times thus reaching certain demands of granular strength.
processing and handling. to produce pellets or extruded feeds of acceptable quality the particle size of the ground materials must be correct. generally speaking finer grinding will result in a better quality pellet or extruded feed increases the capacity of the pellet mill or extruder and
the pelleting process starts with a bin (figure 1 item 1) in which the mixture of mash is stored. from there the mash will flow by gravity into the pellet mill (figure 1 item 2). this machine is usually located on the ground or main work floor level. the hot extruded mash (pellets) flows by gravity into a
