A pellets making machine is a type of molding machine that can manufacture materials into specific shapes, and it has very important applications in the plastics industry. This article will give a brief introduction to how to choose a pellets making machine.

Why can pellets making machines achieve energy savings?

The energy efficiency of a pellets making machine is a major factor in purchasing a pellets making machine, as most factories want to spend the least amount of money. Energy-saving on pellets making machine can be divided into two parts: one is the power part and the other is the heating part.

The power part of the energy-saving: most of the use of inverters, energy saving by saving the residual energy of the motor, for example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production is enough to produce, that excess energy consumption is wasted, the inverter is to change the power output of the motor to achieve the effect of energy-saving.

Heating part of energy-saving: heating part of energy-saving is mostly used electromagnetic heater energy-saving, the energy-saving rate is about 30%-70% of the old resistance circle. Induction heating has the following broad advantages.


  • Compared to resistance heating, induction heaters have an extra layer of insulation, and the utilization rate of heat energy increases.

  • Compared to resistance heating, electromagnetic heaters act directly on the material tube heating, reducing the heat transfer heat loss.

  • Compared with resistance heating, the heating speed of the induction heater is more than a quarter faster, reducing the heating time.

  • Compared with resistance heating, electromagnetic heater heating speed, the production efficiency is increased, so that the motor is in a saturated state so that it reduces, high power low demand caused by the loss of electrical energy.


How to buy and sell pellets making machine?

The following are the key points for purchasing a granulator.

  • Use a daughter machine, double screw feed.

  • The reduction box should be good, the gears inside must be heat-treated and the bearings adjustable.

  • Gearbox, screw, barrel, head and wear parts should be used by strength treatment, life guarantee more than 1 year.

  • The main parts should be made of standard materials.

  • Reducer and motor to buy professional manufacturers to produce sets, do not buy the granulator manufacturers to assemble their own.

  • To have a power distribution work cabinet.

  • The most critical equipment is the quality of the screw and barrel to be good.

  • The washing machine must be continuous production, without stopping to change the water, with a cleaning pool, otherwise, the efficiency is extremely low.

  • Heating should be segmented, and segmented heating should be uniform and controllable.

  • To have a supporting waste plastic washing machine, using recycled water, without the discharge of sewage.

  • Efficient power saving.

  • The length-diameter ratio of the machine must not exceed 20 (in 16:1-20:1 is appropriate, that is, the length of the screw is 16-20 times the diameter of the screw).

  • The model must not be smaller than 100, the larger the output the higher.

  • To have a double exhaust.

  • Pellets making machine flange (die) heating power is very important, to be designed by 2.5W per square centimeter (cross-sectional area).
