One of the major differences in the sequence of operations between fruit and vegetable canning is the blanching operation.

Face mills are tools with a large diameter that are used to cut a wide shallow path for facing operations. Facing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out.

BALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume.

The used m ills in paints industry is rotary mills and ball mills, and as mentioned previously using ball m ills is better than rotary mill. 3.5.1.1: Rotary mill

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The following operations are each defined by the type of cutter used and the path of that cutter to remove material from the workpiece. End milling - An end mill makes either peripheral or slot cuts, determined by the step-over distance, across the workpiece in order to machine a specified feature, such as a profile, slot, pocket, or even a ...
