Precautions for using granulator

  I. Precautions 
  1. The granulator must operate in a forward direction; avoid inversion. 
  2. The granulator prohibits the no-load operation of the air-conditioner and must be operated by feeding the heat engine so that sticking (axis-holding) phenomenon can be avoided. 
  3, feed inlet of the granulator, it is strictly prohibited to enter the iron and other debris inside the vent hole. In order to avoid unnecessary accidents, affect normal production safety. 
  Second, the granulator should pay attention to the work process 
  1, always pay attention to body temperature changes, with clean hands touch the sliver does not change hands, should immediately warming. Until the sliver is touched as normal. 
  2. When the bearing of the reducer is burning hands, or accompanied by noise, it should be stopped and repaired in time, and add refueling. 
  3. When the bearing parts at both ends of the main bearing room are hot, burning hands or noises, it is necessary to stop the inspection and add butter. In normal operation, the bearing compartment is 
  filled with butter every 5-6 days . 
  4, pay attention to clear the machine's operating rules; such as: high or low temperature, speed, speed, according to the circumstances, in a timely manner. 
  5, when the fuselage is not stable, you should check whether the gap between the couplings is too tight. 
  Third, the first boot operation method 
  1, before the start, first warm up for about 40 minutes. Raise the temperature to pull the motor's V-belt by hand until it is free; pull it eight to ten times in the normal working direction. Then continue to heat up for about ten minutes, and then start the machine, but continue to heat, because the normal production needs to continue to add heat; 
  according to different properties of plastic to adjust the temperature.
