"Dalian made" large continuous mixing extrusion granulator passed the appraisal in Beijing

Dalian Daily, December 10, 2019

    News (Li Changmin reporter Li Nan) on December 9, dalian rubber plastic machinery Co., LTD. Developed an annual output of 300,000 ~ 350,000 tons of large continuous mixing extrusion granulator, in Beijing smoothly through the organization by the China Machinery Industry Federation of research and development and application results appraisal.
The appraisal committee is composed of 14 experts from China General Machinery Industry Association, China Plastics Machinery Industry Association, South China University of Technology, Beijing University of Chemical Technology, Petrochemical Design Institute and users.
Listened to the project team technical summary report, testing report, on-site test reports, use of the user, such as reporting, consult the relevant technical documents, after inquiry, answering questions and discussion, the appraisal committee agreed that the results with independent intellectual property rights, broke the blockade of foreign technology and market monopoly, the overall technology has reached the international advanced level, the double support rotor continuous mixing in the lead internationally, such as underwater granulation technology;
The results have significant economic and social benefits.
The unit is currently the largest domestic polyethylene large extruding and granulating machine group, in the process of development, the cracked rotor alternating load resistance, melt self-lubricating bearing, large, complex shape surface of rotor and barrel processing, surface strengthening and heat treatment technology and technical problems, such as developed online monitoring, fault diagnosis, predictive maintenance and one-click drive intelligent control system, such as long cycle and stable operation of provides the technical support.
The unit has been granted 17 invention patents and 12 utility model patents.
Formulate 2 national standards and 2 industrial standards.
Since October 2016, a model unit in TRW in ordos coal deep processing demonstration project in succession and polyolefin plant branded on coal chemical projects coal to olefin plant put into use, to realize the long cycle and stable operation, the field test, capacity, power consumption, vibration, etc. The main technical indicators fully meet the design requirements, can effectively replace imported products, greatly promoted the Chinese petroleum and chemical industry in the structure optimization adjustment, coal chemical industry rapid development, and led the world clean coal utilization, etc.
