Mixing, Calendaring or Refining Mill Roller

Mixing mills or refining mills, also known as =mixing machines used in the rubber,tire or plastic industry to process raw materials into more usable compounds. Let’s take rubber refining mills as an example: Inside the mills, rubber bales are fed through large roller assemblies which help breakdown, soften, and create a more homogeneous blend of the rubber.

The alloy rolls used in rubber open mixing mills, rubber mixing machines ; rubber fining mixers ; rubber mixing mills, plastic mixing mills, roll open mixing mills are critical components and have a significant impact on the mill’s performance and efficiency.

The rollers are typically made of cast iron, forged steel, or chrome plated steel to withstand high pressures and wear. Roller diameters range from Φ216 mm to Φ710 mm. Larger diameters provide higher nip pressures for better refining. Roller length correlates to the width of the rubber sheet. Common lengths are between Φ990mm to Φ2200mm.
