ATTRITORS are used for fine grinding, dispersing of paints, gravure inks, chocolates, dyes, ceramics, high alumina, zirconium, ceria, rare earths, titanium, minerals, chemicals etc. While occupying less space and consuming less power, these attritors are 10 to 100 times faster than the conventional ball mills. Thus they are highly efficient.

A standard attritor consists of a vessel with milling media in which specially designed agitator rotates to achieve fine grinding and dispersion. Usually, the heat generated in milling is removed by cooling. In certain applications, hot water is circulated through the jacket.
Depending on the application, material of construction is chosen. Vessel is made in MS, SS, MS lined with rubber or polyurethane. Quick release coupling between agitator shaft and the drive shaft is provided. Measurement of temperature and control are optional. Tilting arrangement is also provided as an option.
Grinding media: Steel balls or flint, steatite balls of size ranging from 2mm dia to 12mm. Based on capacity and mode of operation, laboratory, batch, continuous and circulation type attritors are available.
Laboratory Attritor : 0.75 litre to 5 litre capacity vessel volume attritors are generally used for laboratory requirements.
Batch Attritors : 80 litre to 1100 litre vessel volume attritors are used to process pasty materials & viscous materials like chocolate paste. The operation is batch wise. The material is fed, attritor is operated for a certain time and the product is removed.
Continuous Attritors : In these, the feed enters from the bottom, flows through the attritor and is discharged through a side nozzle at the top of the medium level. These are suitable for continuous large scale production for single pass grinding or processing applications. Typically, these are used for cocoa liquor, compound coatings and such applications. 15 litres to 400 litre capacity attritors are used for continuous applications.
Circulation Attritors: The system consists of an attritor, pump and a holding tank which has a capacity of about 10 times that of the attritor. Slurry is circulated through the attritor using a pump from the tank till the desired fineness is achieved. 15 litre to 400 litre attritors are used for the continuous operation.
Volume of product processed is usually about 40 ~ 50 % of the total volume.
Drive and power transmission: Induction motor, pulleys, V belt and gear box.
Loading and unloading: Loading for batch operation is manually through the top. Unloading is through grill and valve at the side or bottom.
Murhopye offers laboratory, batch, continuous and circulation attritors over the entire range of capacities and can supply in any of the material of construction mentioned above. Custom designed attritors can also be offered to suit a particular application.
