2. Rolling Cluster Mill: ( Types of Rolling Mills ) A rolling mill with four levels is known as a cluster rolling mill. Each of the two working rolls within this rolling mill is backed by two or bigger backup rollers that can roll rigid materials. Rolls with a minor diameter but a very long length may be required to get the effect sought.

WhatsApp: +86 18838072829Ball Mill Working Principle. In the case of a continuously operated ball mill, the material to be ground is fed from the left through a 60° cone, and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down from near the top of the shell
WhatsApp: +86 18838072829Working Principle of Rolling Process: The rolling process is a metalforming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. This process is mainly focused on the crosssection of the ingot or the metal which is forming.
