I would like to open a waste plastics processing granules factory, to those techniques and attention. What are the processes?
Two, how to purchase, buy what kind of machine?.1, with a machine, double screw feed2 、 the gear box is better, the gears inside must be treated by heat treatment, and the bearings can be adjusted3, gear box, screw, barrel and die and wear parts to the strength of life, to ensure that more than 1 years4. The main parts should be made of standard material5, reducer and motor purchase, professional manufacturers, production kits, do not buy granulator manufacturers to assemble their own6, to have power distribution cabinet7, the equipment is the most critical screw and barrel, good quality8, washing machine must be continuous production, without stopping water change, cleaning pool, otherwise the efficiency is very low9, heating to subsection, paragraph heating to uniform control10, there should be a matching waste plastic cleaning machine, the use of recycled water, do not waste water11, electricity saving, not more than 300 degrees per ton12, the machine's length diameter ratio can not exceed 20 (in 16:1 - 20:1 is appropriate), that is to say, the screw length is 16 to 20 times the diameter of the screw13, the model may not be small 100, the greater the output14, should have double exhaust15, the heating power of the flange (die head) of the granulator is very important, and it should be designed according to 2.5W per square centimeter (sectional area)
(two) technical guidelines for the purchase of advanced waste plastics granulator;First, the characteristics of advanced waste plastics recycling machine:1 、 high efficiency and energy saving (high output, electricity saving);2, environmental protection (supporting cleaning machine, using recycled water, no sewage);3, the quality of vulnerable parts (especially screw) (after nitriding or 45 steel quenching and tempering, strength treatment);4, specific requirements:The power consumption per ton of granulation shall not exceed 300 degreesBring water productionDrainage and exhaustThe automatic non-stop screen changing (preferably two)The produced particles have a high degree of finish and compactnessThe mechanical properties, leading screw designThe application of HDPE (high density polyethylene), LDPE (low density polyethylene), PP (polypropylene), PS (polystyrene), PC (polycarbonate), PVC (polyvinyl chloride) resin, regeneration granulation, granulation, powder granulation PET and ABS all kinds of plastic.The customer service service.Single screw mixing head equidistant designThe double screw feed, coal (gas) dual power11, material: 38CrMnAl, at least 45# steel quenched and tempered screw12, accidental protection device "cross slider.""13, a number of wet dual-use, longer on the machine. But the general water making machine barrel length not less than 2 meters, otherwise easily was born (refers to electricity)14, models should be 120, 180 and 150, the ratio of length to diameter in 16:1 - 20:1 is appropriate
Several important points should be paid attention to when choosing plastic granulator(1) 1. determine the type and yield of the main granulation plasticsThis is the most critical step, don't fall into the trap of a plastic granulator is to do all the plastic. Because of the different plastic plasticizing and extruding pressure requirements are not the same. But the plastic granulator generally of plastic recycling and granulating of our daily life. But for some special engineering plastics such as plastic, crosslinked poly, plastic granulator etc must be special. The yield is mainly decided to purchase different types, namely the screw size, but not only because of the specific models, with different types of the manufacturers is different.2., inspection of plastic granulation machinery manufacturers (technology and services)When you set for your granulation equipment, to the factory inspection (mainly inspect the manufacturers local users and the use of plastic granulator case) is very necessary. Don't be afraid to consult the 02826240333, if the buy is not suitable for their own equipment, consumption is not only these, such as time, human. The important of course is money.When the study is not only to see the equipment manufacturers, but also the customer service service, because no matter how good things are inevitable problems in some aspects, which requires manufacturers technical support. A lot of purchase may not know about the various aspects of the equipment, how to do? This is to rely on their own to truly strength assessment, equipment manufacturers have the technology will not cheating, because this is the real manufacturers put quality in the first place, is the real consideration of sustainable development.It should be noted that, according to their own conditions to assess the situation, not everyone is suitable for plastic granulation, such as factory buildings, electricity (industrial power must be), can find a stable source of plastic and so on.
