What are the cooling methods of the extruder?

The cooling method of the extruder. Extruders with a screw diameter greater than 45mm are equipped with a barrel cooling device. The diameter of the small extruder is less than 45 mm, because the barrel contains less plastic. The remaining heat can be diffused by convection between the barrel and the surrounding medium air. Therefore, the outside of the high-speed extruder usually does not have a barrel with a cooling device.

Cylinder cooling methods are generally divided into air cooling and water cooling.

1. Wind cooling.

The air cooler mainly adopts air cooling. In terms of cooling effect, air cooling is softer, but the cooling speed is slower. In terms of equipment cost, the cost is higher due to the need to equip blower and other equipment. In addition, the air cooler has a large volume, and its cooling effect is greatly affected by the outside temperature.

2. Cooling water.

The water cooling often uses ordinary tap water, so the auxiliary equipment he uses is relatively simple, the water cooling speed is faster, but it is easy to cause rapid cooling, and because the water is generally softened, the water pipe is prone to scaling and rust, while the water pipe is reduced Cooling effect or being blocked or damaged.
