Hammer mill ASTM C289

Hammer mill

The hammer mill is used to reduce the sample size, previously crushed to 5 mm size with the Laboratory Crusher (see link other producs below), in order to perform various tests as, for instance, the chemical properties of aggregates. The grinding operation is obtained by the combination of three efforts: impact, shear and rebound. After entering the grinding chamber through the hopper, the material reaches the required fineness down to 1 mm and through the filtering hoses arrives to the collector. The machine is supplied complete with screens of 3, 2 and 1 mm opening. The material passing to the 1 mm screen goes down practically to powder.

 

This is one of the apparatus required to obtain particles that pass through 300 μm sieve conforming to ASTM C289. See also Laboratory Crusher and Jar Mills in links to other products below.
