The granulator is mainly composed of feeding, mixing, granulating, transmission and lubrication systems. The working process is to require a mixed powder with a water content of not more than 15%, enter the feeding auger from the hopper, adjust the speed of the stepless speed regulation motor to obtain a suitable material flow, and then enter the agitator, stir and steam through the stirring rod Mixing for conditioning, if you need to add molasses or grease, also add it from the mixing drum together with steam for conditioning. The amount of fat added is generally not more than 3%, otherwise it will be difficult to form. After conditioning, the temperature of the mixed powder can reach 64-85℃ , The humidity is 14-16%. Then pass through the chute through the optional iron absorption device to remove the iron impurities mixed in the powder, and finally enter the pressing chamber for granulation.
The feeder is composed of a speed-regulating motor, a reducer, auger cylinder and auger shaft.
The speed regulating motor is composed of a three-phase asynchronous AC motor, an eddy current clutch and a tachogenerator. It is used in conjunction with the JZT controller, and its output speed can be changed through the JDIA electromagnetic speed regulating motor controller.
The feed reducer adopts a cycloidal pinwheel reducer with a reduction speed ratio of 1.10, which is directly connected to the speed regulating motor for deceleration, so that the effective speed of the feeding auger is controlled between 12-120 rpm.
The feeding auger is composed of auger barrel, auger shaft and bearing with seat. The screw auger plays the role of feeding, and the speed is adjustable, that is, the feeding amount is variable to achieve the rated current and output. The auger shaft can be drawn out from the right end of the auger cylinder for cleaning and maintenance.
