    This pelletizer is designed by our company through repeated research on the same kind of production lines in the world, through the cooperation of R&D Department and Technology Department of our Company's technology center with Chinese scientific research institutes, universities and industry elites, combined with targeted special researches on the high labor cost, high energy consumption, plastics easy to aging and other bottlenecks of waste plastic granulation production in the current market. The whole production line is mainly composed of specially designed humanized automatic feeder, mandatory automatic feeder, scientific and reasonable self-heating energy-saving main machine, auxiliary machine, automatic screen changer and wear-resistant granulator. The basic features of the production line are high efficiency, energy saving, economy, environmental protection, good appearance, practicability, high stability and high degree of automation. Besides, the produced plastic particles have stable geometric size, good gloss and no pores and maximum protection degradation. It is the development trend of pelletizer, epoch-making innovation of pelletizer market, the extension of the deep processing project of plastics after crushing and cleaning as well as the ideal choice for investment in and production of waste plastic particles project.
The main application fields of waste plastic particles are as follows: injection molding, blow molding, extrusion molding and compression molding factories. It is widely used, with remarkable cost performance and outstanding competitiveness. In particular, after the domestic prohibition of foreign wastes from entering into China, the demand has soared and exceeded supply in the market.
