Conforms to is: 10050-1981, & astm d 4644
This apparatus is used to assess the resistance offered by a rock sample to weakening and disintegration when
Subjected to drying and wetting in a slaking fluid, usually water. The equipment meets the essential
Requirements of is:10050 -1981 & astm d 4644 and comprises the following:
A motor drive with reduction gear mounted on a base board and capable of rotating four drum assemblies at a
Constant speed of 20 rev/min approximately. The motor drive is totally enclosed in a hinged cover for quick
Accessibility. An operating switch is provided in the cover.
Two / four test drums made of brass wire mesh, with one end closed and having a removable cover on the other
End. They have suitable couplings for mounting in the perplex water troughs. The drums are 140 mm in diameter
And have an unobstructed length of 100 mm.
Two / four perplex water troughs, accommodate one test drum each. These drums carry quick couplings on either
End which are in turn coupled with couplings of the motor drive. The troughs allow 40 mm unobstructed clearance
Below the test drum. A water level mark is provided in each water trough 20 mm below the axis of rotation of the
Drum.
Suitable for operation on 220 volts, 50 hz, single phase ac supply.
