Vibratory mills Description

This is the first mill we will consider which does not rely on rotation for the main grinding action. The vibrating mill is a grinding chamber which is filled to about 65 – 80% of its capacity with grinding media such as balls or rods. The chamber is vibrated at a frequency of between 1000 and 1500 times per minute (can be variable speed) by cams or imbalanced weights.

The grinding action is efficient and thorough. Grinding media material and chamber lining can vary depending on application.

Vibratory mills Characteristics

Vibrating mills can grind hard or soft materials. Maximum throughput is in the order of 20 t.p.h. but feed size should be kept fairly small. Although final product size can be as low as 0.005mm this type of mill is often used for less fine applications. Product size and shape is a function of the time spent in the mill, media type and size, and frequency of vibration. Commonly functions as a batch mill.

Material suitability for vibratory mills: Lime, calcium carbide, alumina, gypsum, bauxite, chromites, limestone , sillimanite, fluorite, pigments, dolomite, magnetite etc.

Vibrating Grinding Mills

Vibratory mills are for continuous or batch grinding materials to a very fine end product. Two vibrating / grinding cylinders are placed either directly above the other or inclined at 30 degrees to perpendicular. Located between the two tubes an eccentrically supported weight is driven to produce a small circular vibration. The tubes are charged with ball or rod media to aid in the grinding action (attrition) from the constant impulses. Material is ground as it travels from the input end of the tube to the outlet end. Conventional tube mills for hard, coarse or if very fine grinding is required are connected in series so the material is ground through the top tube and subsequently through the bottom tube. If each tube is charged separately the grinding of the material is subsequently not so intensive. Useful for soft feed materials or if a low degree of fineness is required. Center feeding is also possible.

Vibratory grinder mills or vibrating mills have a very small size and low energy consumption (based on throughput) compared to other mill types. Grinding operations can be performed either wet or dry. Three tube vibratory mill configurations are also available.
