At present, most polymer blends, the main equipment used by manufacturers is single screw extruder, twin screw extruder, but! There is a device that is indeed an upgrade of these two devices! That's a double-rotor mixer! Below, Xiaobian will jointly decrypt this model for everyone!

In fact, when it comes to the extrusion industry, each equipment has its own advantages and disadvantages, including single screw extrusion has the advantages of simple structure, easy manufacturing, low cost, but the mixing ability is poor; As a mixing equipment, the twin-screw extruder has outstanding mixing characteristics, but the filling mixing capacity is weak, and the energy consumption per unit product is high. The mixer is widely used in plastic mixing, but the intermittent operation has unstable product quality, unreasonable energy utilization, and high energy consumption per unit product.

So, because these devices themselves have become increasingly unable to solve the needs of customers, then is there a model that can solve the needs of customer product quality? Can rational use of energy, reduce the energy consumption of products?

Of course there is! That's the continuous mixer! Also called double rotor continuous mixer!

The double-screw continuous mixer gearbox uses the ZLYJ series, a high-quality hard-toothed surface gear transmission device designed specifically for single-screw rubber and plastic extruders, with the output shaft made of high-quality 42CrMo. Other gears and shaft components are made of high-quality 20CrMnTi material. The gears of the double-screw continuous mixer are carburized, quenched, and ground, with high precision and hardness. The gear precision is GB10095-88, Grade 6, and the surface hardness is HRC-54~62. An anti-axial thrust bearing is installed at the front of the hollow output shaft to bear the axial thrust of the screw during operation. The entire machine has a small size and high load capacity, with smooth transmission, low noise, and high efficiency. Furthermore, based on the high-stretch chaotic type screw, the plastic melting process in the continuous mixer is in a dispersed melting state, increasing the heat transfer efficiency and melting speed. By establishing energy coupling between the melting zone and the mixing zone of the continuous mixer, the heat demand of the solid resin during melting is solved by utilizing the heat dissipation generated during mixing. By establishing an efficient stretching flow in the mixing field, the mixing efficiency is increased. Ultimately, the energy consumption of the entire mixing process is greatly reduced!

Next time, I will introduce the characteristics of the COLOWE double-rotor continuous mixer.
