Page 26: Safety System
Safety system The safety system consists of overload protection, pellet chamber door protective switch and external discharge of meal. 4.5.1 Overload protection device When any foreign hard materials enter the pelleting area, or the feed flow rate is in excess, the pressure between die and rollers will exceed the normal design work- ing torque for the main shaft, and thus the shearing force transmitted to shear pin will exceed its shear strength and the shear pin will break. - Page 27 Hot material and steam will cause serious damage , please open the door after close the steam and the material getting cool. Pull the knife out before you open the door, other it will cause damage to the door , when close the door the knife should be postion again at the right position.

Page 35: Commissioning
Commissioning Putting the subassembly into operation 7.1.1 Die-roller clearance adjustment Open the pellet chamber door, loosen the fastening bolts of the feed cone (See Figure 12), hold two handles of feed cone tightly with hands, turn the feed cone clockwise, thus feed cone can be removed. Then clear away the accumulated ma- terial on the inside surface of die (1) and surface of rollers (3), loosen lock screws (2) and retaining nuts (6), twist the adjusting screw (7) so as to make the roller ad- justing quadrant (10) turn. -
Page 36: Knife Adjustment
It is very important to control die-roller clearance correctly. Too small clearance will severely wear rollers and die, too large clearance will affect the output and even pelleting effect. Generally clearance should be 0.05-0.3mm. Clearance between new die and rollers can be measured with feeler gauge. If adjusting the clearance during ordinary production, control clearance to the following manner: when turning die with hands, rollers rotate intermittently and just touch the die through visual in- spection. -

tional speed is mounted on the controller for determining the speed value objec- tively. During the normal operation, the variation of working current of main motor should be observed when adjusting the rotational speed of the feeder. When speed and product output are increasing, the working current of main motor must not ex- ceed the rated value (Refer to the rated value stipulated on the nameplate of main motor). -
