Four-Rolls Rubber Calender for Rubber Sheet Processing

Rubber calender is the basic equipment in the process of rubber products, it is mainly used to put rubber on fabrics, to rubberize fabrics, or to make rubber sheet.

Features:
1. Rolls: chilled alloy cast iron rolls with surface hardness 68~72hs. the rolls are mirror finished &

polished, duly grinding and are hollowed for cooling or heating.
2. Roll clearance adjusting unit: nip adjustment at two roller ends is done manually using two separate

screws attached to the brass housing body.
3. Roll cooling: universal rotary joints with inner spray pipes with hoses and headers. piping is complete

up to supply pipe terminal.
4. Journal bearing housing: heavy duty steel casting housing fitted with anti friction roller bearings.
5. Lubrication: full automatic grease lubrication pump for anti friction roller bearings fitted in dust

sealed housing.

6. Stand frame & apron: heavy duty steel casting.
7. Gearbox: hard-tooth reduction gearbox, GUOMAO brand.
8. Base frame: common base frame heavy duty, steel channel and ms plate fabricated accurately

machined on which whole machine with gearbox and motor are fitted.
9. Electric panel: star delta electric operating panel with auto reversing, voltmeter, ampere, overload

protection relay, 3 phase indicator and emergency stop switch.

Rubber calender is an industrial machine used in rubber processing to produce sheets, films, and coated materials with uniform thickness and high-quality surface finish. It works by passing rubber compound through a series of heated rollers that apply pressure and shape the material according to required specifications.

The rubber calender is widely used in tire manufacturing, conveyor belt production, rubber flooring, and waterproof materials. It ensures consistent thickness, improved density, and smooth surface quality, which are essential for downstream processing and final product performance.

Made with high-strength steel rollers and precision control systems, the machine offers stable operation, adjustable speed, and accurate thickness control. Rubber calendering is a key process in industrial rubber production, helping improve efficiency, product quality, and material performance.
