Three new breakthroughs in underwater granulation technology

breaking the production bottleneck of 100t/h

at this year's K exhibition, Coperion's booth B33 in hall 14 will be the most eye-catching template of the world's largest underwater pelletizer ug1250. It breaks a series of template manufacturing limits: the average cutting diameter is 1250mm and up to 11000 mold holes

ug 1250 underwater granulator size is amazing

in the template manufacturing process, wear protection and uniform distribution of melt on the cutting ring are unprecedented challenges. The PE output of ug1250 can exceed 100t/h, and the water volume can reach 1500m3/h. The supporting hydraulic and drive system has been long-term verified on other models. The first ug1250 will be put into use soon. Ug925 with smaller size but the same structure has been put into use in mid-2009

copetron has also built a special large underwater granulator for thermoplastic elastomer: ug750 will be put into use in early 2011. Because the viscosity of TPE particles is very large, the radial flow along the knife axis to the granulation cavity and the axial flow along the knife to the granulation cavity minimize the turbulence in the granulation cavity. This can reduce the collision between newly cut particles with high viscosity, so as to avoid sticking

the high wear-resistant system meets the granulation needs of glass fiber reinforcement

bruckmann kreyenborggranuliertechnik (bkg) will demonstrate its professional and technical ability in the design of wear-resistant granulation equipment. At present, bkg has 15 underwater granulation production lines (uwp) designed with wear-resistant components in the world, which are used to produce glass fiber reinforced plastic pellets. Through continuous improvement of various component designs, the maintenance and operation costs of wear-resistant uwp have been reduced by 50% in the past five years

the new generation of sphere granulator is not only convenient to operate, but also has high energy-saving efficiency.

during the granulation process of glass fiber reinforced plastics (GRP), the machine components are inevitably worn. Uwp has obvious advantages in granulating such materials. Uwp fully automatic operation is very economical, especially under the high material processing capacity of up to 6 tons/hour. This kind of GRP material is very brittle, and the strip will often break when using the commonly used stretch granulation process. Uwp can completely eliminate the problem of strip fracture, so few operators are required. In addition, the amount of waste produced in the process is greatly reduced. Uwp starts very fast, generally only takes minutes, and the production process is economical and efficient

bkg underwater pelletizing system has made a lot of innovative designs to improve the wear resistance of parts

in addition to its compact structure, uwp process has other important advantages. The granular material is contained in a closed process water circulation system, which is not in direct contact with the ambient air, so it will not discharge steam or dust to the production area. Finally, cutting the plastic melt underwater can ensure that the glass fiber is well coated in the particles

uwp process has a proud industry in the production of PP, PBT, PC and PA Blends with glass fiber content up to 66%, mainly due to high product quality and full-automatic operation mode of the equipment

in addition, in order to reduce the production cost of GRP pellets per ton, the cutter head of the granulator is made of special materials with excellent wear resistance. The service life of each side of the cutter blade is days. The template can be used for up to 1 year. The equipment is equipped with surface grinding tools, which can easily regrind the cutting surface without removing the formwork from the machine. The box knife rest cavity and the process water inlet and outlet pipes are equipped with wear-resistant lining to ensure long service life. The pellet catcher is equipped with a hardened wear-resistant threaded rod, which can be quickly replaced if necessary. The dryer is redesigned so that it is no longer necessary to replace the whole rotor after wear, but to replace a single component, thereby greatly reducing the cost. All components, such as rotor lifting mechanism and outlet and inlet devices, are made of wear-resistant materials

higher energy efficiency and more convenient operation

convenience of operation is an important problem for underwater granulation

at this year's K exhibition, automatik will exhibit a new generation of sphere underwater granulation solutions. The company will exhibit sphero70 at booth 9a04. This is the first public appearance of the company on an important occasion after its merger with maagpump

the new generation spbruckmannkreyenborggranuliertechnik (bkg) will demonstrate its professional technical ability in the design of wear-resistant granulation equipment.

The service life of each side of the cutter blade is days. The template can be used for up to 1 year.

The box knife rest cavity and the process water inlet and outlet pipes are equipped with wear-resistant lining to ensure long service life. The pellet catcher is equipped with a hardened wear-resistant threaded rod, which can be quickly replaced if necessary.

higher energy efficiency and more convenient operation

convenience of operation is an important problem for underwater granulation

hero granulator adopts the improved pellet water slurry straight-line outlet design, so the process water flow is better and the demand for energy is reduced. It also adopts a new interlock device, which can easily open the pelletizing chamber with one hand, which is a new technology

the advantages of linear process water design (i.e. flowing into and out of the pelletizing chamber along the tangential direction) are easy to clean, reduce wear, and prevent agglomeration in some demanding occasions (such as processing thermoplastic elastomers). In addition, the cutter head assembly is redesigned, and a new type of universal joint is adopted, which can make the cutter edge always accurately locate with the template, and prolong the service life of the cutter by 30%

the process water treatment device in the new version of sphere has a compact structure and is pre configured before leaving the factory, so it can be installed quickly and conveniently. Similarly, the process water system is very convenient to use during operation. Compared with drawer filter, curved filter and vibration filter, the new inclined filter is an efficient and economical alternative

when redesigning the sphere product series, the high reliability of operation and easy installation are the priorities of ottomatik. All electrical components are pre configured with cables and plugs to achieve "plug and play". In addition, the operation of upstream equipment such as extruder has also been improved, with ample space and convenient operation

the new generation of sphere models has significantly improved energy efficiency. In addition to using the straight-line outlet of granular water mixture to reduce the energy demand, the energy consumption of drying blower is reduced by 50%. New superflow heat insulation formwork is adopted to further reduce energy consumption. The working range of sphere series equipment is expanded, such as anti slip coefficient and axial force. The existing models from sphero50 to sphero350 with a maximum production speed of 18 tons/hour are extended to sphero560, which can strengthen and maintain the tightening effect by making the skin produce deformation memory, and the processing capacity is as high as 32 tons/hour. The range of options is wider, and the basic models can be customized to accurately meet the specific requirements of different customers
