Attrition mill : IN this case, the charge is ground to fine size by the action of a vertical shaft with side arms attached to it. The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the

mechanism in a roller mill can be strictly compression or a combination of compression and attrition. A roller mill can achieve particle sizes as fine as d97 = 10 microns (97 percent of the particles having a diameter of 10 microns or less) and is suitable for friable materials. Both table and ring roller mills have long been used to

Cylindrical zirconia or stainless-steel grinding media should be used for effective grinding of the powder. Union Process Attritor Mill. The attritor mill is a wet grinding attrition mill. It differs from conventional ball mills as it uses much smaller media with diameter less than 5mm, leading to greater media-material contact area.

Attrition mills are more appropriate for "mid-range" size particles. Such mills utilize 3–10-mm media to produce material ranging in size from approximately 1 to 10 microns. The first "small media" mill was introduced about 60 years ago. It was named a "sand mill" because it used 1/64–1/8 in. Ottawa silica from Canada.

This process grinds the powder materials by impact/collision & attrition. • Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid.

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.
