12-station roll-reducing machine

The 12-station roll-reducing machine multi-pass progressive compression, increases the density of magnesium oxide to over 1.65-1.75 g/cm³, thereby significantly improving the heat transfer efficiency, insulation strength, and mechanical stability of the heating element. Whether in home appliances or industrial applications, this equipment is a key process tool for achieving quality upgrades in heating element manufacturing that pursues higher power density, longer lifespan, and greater safety and reliability.

1. The 12-Stations roll-reducing machine body utilizes an integrated coin structure, resulting in minimal distortion, high precision, and long-lasting durability.

2. As the pipe diameter decreases, the speed rate of each pair of axis wheels increases. This ensures good linear characteristics and minimal distortion after pipe shrinkage, leading to elongation length and material savings.

3. During the adjustment of the roller compression ratio, the roller's high center remains unchanged.

4. The compressed pipe exhibits high geometric precision, with ovality maintained at less than 0.05.

5. The motor is equipped with overload protection, automatically stopping in case of blockage.

6. The pipe shrinking speed reaches 18m/min, ensuring high efficiency.

The 12-Stations roll-reducing machine can also be used with an automatic feeder. The operator simply places the tubes to be processed into the feeder hopper in batches; subsequent sorting, loading, high-pressure testing, conveying, and tube shrinking are all completed automatically. An integrated solution of "automatic feeding + intelligent sorting + precision tube shrinking."

 The 12-Stations roll-reducing machine is used for compacting elements in order to increase the density of MgO. The speed rate of each pair of axis wheels will increase while the diameter of the pipe changes. Compression and elongation of the tube tend to match the variation. It's not easy to roll pipe blockage in the pipe elongation ratio constant rolling machine increased by 5%. And with a fixed-size trench roller R series, its heating element professional first choice, an ideal product.

Technical Parameter Classification

Pipe Diameter Range: Applicable to outer diameters of Φ6mm-Φ25mm (specific range depends on equipment capacity).

Wall Thickness Range: Applicable to pipes with wall thicknesses of 0.4mm-1.5mm.

Between Reduction Ratio: Continuous online diameter reduction (e.g., Φ12mm→Φ10mm) is possible, increasing density by 20%-40%.

 The  12-Stations roll-reducing machine is widely used in the production of heating tubes. Mainly in household appliances heating tube and industrial heating elements:

Household Appliances
