Sturdy Base Vibrating Machine

Vibration machine is used for the preparation of mortar cubes for the determination of compression strength of ordinary and rapid hardening portland cement, low heat portland cement, portland bleast furnace cement and high alumina cements. 
The machine consists of a vibrating frame assembly and an electric motor mounted on a sturdy base. The complete frame assembly consists of a vice to hold a 7.06cm cube mould and two studs threaded at top and a hopper to feed the sample in the mould. This assembly is supported on four springs and has an in built rotating shaft which rotates eccentrically and thus imparts vibrations to the entire frame.
