Vertical vs. Horizontal Milling and Turning - 3ERP
Vertical milling is most applicable to projects where the main focus of the object in question is on one particular side. This can be something like a large metal plate or a sinking die. They also have the benefit of being generally less complex than horizontal milling machines, being both cheaper and easier to use and maintain for this reason.

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
Ball Mills - Mineral Processing & Metallurgy
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Milling is used to remove a layer of material from the work surface. It is also used to produce a cavity in the work surface. In the first case it is known as slab-milling and in second case it is known as end- milling. Basically, the milling process is used to produce a plane or straight surface. The cutting tool used has multiple cutting edges.
