The granulator is mainly composed of feeding, mixing, granulating, transmission and lubrication systems. The working process is to require a mixed powder with a moisture 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 and conditioning. If you need to add molasses or grease, add it from the mixing drum and temper it with steam. The amount of grease added is generally not more than 3%, otherwise it will be difficult to shape. After conditioning, the temperature of the mixed powder can reach 64-85℃ , Humidity reaches 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.
Feeder
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 tachometer generator. It is used in conjunction with the JZT controller, and its output speed can be changed through the JDIA electromagnetic speed regulating motor controller.
reducer
The feed reducer adopts a cycloid 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. [1]
Feeding auger
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.
