Pelletizer market prospects and purchase guide

Market prospects for granulators

At present, the plastic granulator used in the petroleum and petrochemical industry is becoming more and more large-scale, and due to strong demand, the situation of tight supply and prolonged delivery is becoming more and more prominent. Plastic granulator refers to a unit that adds different additives to the resin according to different purposes, and is heated, kneaded and extruded to make the resin raw material into a granular product suitable for secondary processing. The plastic granulator is widely used in petroleum. Petrochemical industry. At present, there are two large granulator manufacturers in the world, one in Japan and one in Germany. The Japanese Kobe Steel Company has a very high market share in the Chinese market.

According to industry experts, due to the rapid development of the global petrochemical industry in recent years, the demand for plastic granulators has increased rapidly, plastic granulators have become more and more large, and users have mechanical stability and energy saving requirements for the unit. It is getting higher and higher. The main reason for the current difficulty in supplying granulators and prolonging the delivery period is the increase in demand.

Granulator selection guide

1, with the mother machine, double screw feeding

2, the gearbox is better, the gear inside must be heat treated, the bearing can be adjusted

3, gearbox, screw, barrel, head and wear parts should be treated with strength, life guarantee for more than 1 year

4, the main components should use standard materials

5, reducer and motor purchase professional manufacturers to produce suits, do not buy granulator manufacturers themselves assembled

6, there must be a distribution work cabinet

7, the most critical of the equipment is the quality of the screw and barrel is better

8, the washing machine must be continuous production, no need to stop water, use the cleaning pool, otherwise the efficiency is extremely low

9, heating should be segmented, segmented heating should be evenly controllable

10, there must be a matching waste plastic washing machine, using circulating water, no need to discharge sewage

11, efficient energy saving

12, the machine's aspect ratio can not exceed 20 (in the range of 16:1-20:1, that is to say the screw length is 16-20 times the screw diameter)

13, the model can not be small 100, the greater the higher the output

14, there must be double exhaust

15. The heating power of the granulator flange (die) is very important. It should be designed according to 2.5W per square centimeter (cross-sectional area).
