Hammer mill for laboratory 48-D0535/A

Hammer mill for laboratory

Model : 48-D0535/A Hammer mill for laboratory. Maximum capacity 50 Kg/h. 380V/50Hz/3ph

Brand/Supplied From : Controls – Italy

Standards : ASTM C289

ASTM C289 : 1.1 This test method covers chemical determination of the potential reactivity of an aggregate with alkalies in portland cement concrete as indicated by the amount of reaction during 24 h at 80°C between 1 N sodium hydroxide solution and aggregate that has been crushed and sieved to pass a 300-μm sieve and be retained on a 150-μm sieve.

Description

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.
