What is attritor mill?

Attritors or stirred ball mills are a simple and effective method of grinding and dispersing fine and homogenous material quickly. The Attritor can operate wet or dry, introduce inert atmospheres, operate at controlled temperatures, and vary grinding speed.

What is an attritor?

attritor (plural attritors) A type of grinder in which particles suspended in a liquid are moved by paddles and are ground as they collide with each other or with the grinding medium.

What is the most preferrable milling technique?

ACMs are the most widely used milling technology in the powder-processing industry today for the general size reduction of fine chemicals and food products. The basic advantage of these mills is that they grind and classify in one step.

What is the principle of fluid energy mill?

Principle: Fluid energy mill operates on the principle of impact and attrition the feed stock is suspended with in a high velocity air stream. Powder is introduced through the inlet of venture. Air introduce through the grinding nozzles transport the powder in the circular track of the mill.

What are the two main types of milling operations?

There are two major classes of milling process: In face milling, the cutting action occurs primarily at the end corners of the milling cutter. Face milling is used to cut flat surfaces (faces) into the work piece, or to cut flat-bottomed cavities.

What is advantage of fluid energy mill?

Advantages of Fluidized Energy mill 1. The machine has no moving parts and thus the tendency of contamination due to wear of parts is minimized. 2. The equipment is easily sterilized.

Which fluid is used in fluid energy mill?

The energy for milling is provided with a compressed fluid such as compressed air, or in the case where materials being milled provide a risk of a dust explosion, gaseous Nitrogen. The compressed fluid issues through the nozzles forming a very high velocity tangential circle within the grinding chamber.
