Materials for laboratory mills:

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
