4 Roll Calender Machine For Sale

4 Roll Calender Machine is one of the specifications of rubber calender machine, which is used for processing rubber, plastic, silicone and so on. Different from 3 Roll Calender Machine, 4 Roll Calender has two pairs of rollers, one on top and one on bottom, which work together to process raw materials.

When working, the raw material is firstly fed into the machine by the upper feeding roller, and the rollers of the upper and lower roller groups work together to extrude the material. Before entering the lower roller group, the materials are crushed many times and gradually become diluted materials sent out by the discharging roller.

Structural characteristics

Upper roller group: including upper feeding roller and upper calendering roller. Among them, the function of upper feeding roller is to introduce raw materials into the working area, while the upper calendering roller is located above the upper feeding roller for applying processing pressure. Both of them cooperate with each other.

Lower Roller Group: Includes the lower feed roller and the lower calender roller. The lower feed roller is mainly responsible for receiving and conveying raw materials. And the lower calender roller is located below the lower feed roller for applying processing pressure.

Roller Diameter and Length: The diameter and length of each roller can be customized according to the specific application. The rollers in the lower roller set are larger than the rollers in the upper roller set to help provide processing pressure.

Roller material: The rollers are made of wear-resistant alloy steel and cast iron to withstand high pressure and friction.

Roller surface treatment: the surface of calendering rollers has a specific texture, and the texture can be customized according to the needs.

Roller spacing adjustment device: This device allows the operator to adjust the spacing between the upper and lower roller sets to control the thickness of the processed material.

Drive system: The machine is equipped with a powerful electric motor that provides sufficient torque and speed to ensure smooth operation.

Safety devices: To ensure the safety of the operator, the machine is equipped with safety devices such as emergency stop button, safety fence and guard.

Feeding system: The machine is equipped with automatic or manual feeding system, which can easily introduce raw materials into the working area.
