What are the main parts and functions of the small mixer?

Small mixer: the roller is the main component of the mill. In the course of the work, it directly contacts with the rubber and produces compression and shearing action on the rubber.

Open mill requirements:

1. to have a certain mechanical strength and stiffness, can withstand the force of the rubber compound;

2. roller work surface should have higher wear resistance and corrosion resistance, and the surface hardness is not less than Shaw's 65 degrees;

3., from the structure, it has a reasonable geometric shape, to prevent excessive stress concentration;

4., good thermal conductivity, easy to glue the heating and cooling;

5. the manufacturing process is simple and the cost is low;

6., the diameter error is 1 ~ 0.5mm, the surface roughness is 3.2 ~ 1.6, the factory inspection must guarantee the roller diameter to have the positive deviation.

Mill material:

Generally use chilled cast iron, surface layer of hard, wear-resistant, white layer hardness is not less than Shaw's 65 degrees

Structure: the roller is mainly composed of a working part of diameter D (called roller body) and a support part with diameter of D1, which is called a roller diameter and a transmission part of diameter d3.

Sort:

The classification method is mainly based on the surface shape of the roller. Generally divided into:

A. smooth cylindrical roller (cylindrical surface)

B. drum roller for reclaimed rubber refining,

C. with grooved roller breaking, wash,

According to heating and cooling form, it is divided into hollow and drilling type

According to the heating medium, it is divided into electric heating, steam heating, oil heating and constant temperature water

According to whether the diameter of the front and rear rollers is the same: the same diameter and different diameter
