What are the heating methods suitable for polypropylene spinning machines? The heating of the polypropylene spinning machine requires the use of electromagnetic heaters. The main component of the machine is the heat roller, which can be heated to a certain temperature and runs at high speed.

The size of the heat roller is different, generally there are diameters Φ160 Φ180 Φ190 Φ210 Φ220. Length of hot roller: 200-450mm, speed range: 750-5500m/min, surface temperature of godet: ≤240℃-140℃, surface treatment of hot roller: hard chrome plating, ceramic plating.

The current heating method of the heat roller is power frequency induction heating. Its disadvantage is that the heating coil is easily damaged. The frightening thing is that it is easy to heat the central shaft of the motor and burn the motor. However, the newly developed all-digital application in polypropylene spinning machine heating roller heating is efficient and energy-saving, effectively solving the shortcomings of traditional heating and greatly reducing costs. Its main advantages are:

1. Make the surface temperature of the hot roller work area uniform, which can meet the requirements of different industrial yarns and civil yarns FDY spinning process.

2. The surface temperature of the working area of the hot roller rises rapidly, energy saving is obvious, and the efficiency is greatly improved.

3. After using the electromagnetic heater, the rotating shaft of the heat roller motor will not damage the motor due to induction heating.

4. The coil of the electromagnetic heater will not be damaged, reducing maintenance trouble and cost.

5. The equipment has a complete system, simple structure, stable and reliable operation at high temperatures, and can meet the requirements of different fiber FDY spinning processes. It is an economical and reasonable choice for polypropylene spinning machines.
