What is the cooling device of the twin-screw extrudrel

The twin-screw extruder barrel cooling device includes an oil tank with a built-in heat-conducting oil, a high-temperature oil pump is connected to the oil tank, the inlet end of the high-temperature oil pump can absorb the heat-conducting oil from the oil tank, and the output port of the high-temperature oil pump passes through a high-temperature electromagnetic The valve is sequentially connected with an oil filter, a spiral cooling groove of the twin-screw extruder barrel, and a high-temperature oil cooler, the other end of the high-temperature oil cooler being connected with the oil tank. Compared with the prior art, the advantage is that the heat transfer oil is used for circulating cooling, the noise is small, the cooling capacity can also meet the requirements of large extruders, and it will not cause rapid cooling, will not disturb the stable flow of the plastic, and water cooling is easy to generate. Limestone clogs the pipes.

PVC extruder screw and barrel with high hardness

The temperature control device of the rubber extruder includes three heaters connected side by side and a heating wire arranged in the heater. The two ends of the heater are respectively connected with a water inlet pipe and a water outlet pipe, and the water inlet pipe and the water outlet pipe are connected to the Constant temperature water tank; when the heating wire in the heater is energized and heated, each heater can reach a different temperature, so that the internal rubber melts. When the temperature in a certain heater is too high, the heat can be taken away through the circulation of the flowing water in the water pipe. , without oil temperature machine, energy saving and environmental protection and easy to operate.
