Introduction
      As the important equipment on pellet production, SZLH250 pellet mill is specialized in pressing pellets for poultry and livestock feeding and common fish feeding with an annual output of 3 thousand tons, and this equipment is suitable for large and medium-scale feed mills and aquaculture farm.
(Note: the calculated annual output is based on the following condition: )
         Material: corn;
         Moisture: 12%;
         Diameter of ring die hole: Φ4mm;
         Working hours: 8 hours per day, 200 day per year
     SZLH250 pellet mill has been improved and developed by summarizing salient features in  our 18-year experience in design, combining with various advantages of similar machines both at home and aboard.
      Pellet machine manufactures with high output, low noise, low energy consumption, long operating life, convenient operation, and has magnet to remove all the foreign matter. In addition, overload protection is also been added, which can ensure a safe and reliable operation.
     This mill adopts continuous variable motor to control rpm, making it easier to regulate. It is equipped with external discharging mechanism and pressure oil pump lubricating system.
      Pellet Diameter
     This machine is equipped with dies of Φ3, Φ4.5, Φ6, Φ8, Φ10, Φ12, which can be chosen by user according to requirements. (generally, Φ3 for chicken, Φ4.5~Φ6 for pig and fish, Φ6~Φ8 for ox and horse). If necessary, users can choose dies with Φ2 or other custom-made size to suit your own requirements.

     Operation Process
The following is the specific process of operation: prepared powder with about 13% of moisture comes into feeder screw (its rotational speed is adjustable) from hopper and next into mixer. After the stirring of shaft mixer and the mixing with steam, temperature of mixed powder will raise to 70~90℃, and moisture content to 15%. Then coming into feed chute and iron-attractive device, these powders will be purified since all foreign matter will be removed. Finally, all the powders will flow into pellet chamber, which is the place for press the pellets.

     Tips –Steam
      Steam should be added during the operation since it can improve the production. If water is used to replace steam, the output it produced is much smaller to the half, and the power consumption of this pellet mill will increase with a large degree. In addition, using steam can avoid the mill getting rusty, which can prolong the service life.
