Vibrating Machine
Concrete moulds are easily cast by using a tamping bar or a vibrating
table. However air tapped in cement mortar paste can not be thus
removed while casting cement mortar moulds. Easy method is to impart
greater vibration of lesser amplitude to the mould while casting. This
is achieved in a vibrating machine. Vibration machine is used for the
preperation 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.
Salient Features
Specifications :
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. A balance weight is an intergral bottom part of the frame. The centre of gravity of the assembly is brought to the centre of the eccentric shaft or within a distance of 25mm mould. The frequency of vibration is 12000 400 vibration per minute. Supplied complete with on 7.06cm cube mould with loose base plate, a time switch 0-5mins x 1min and certificate of vibration from a standard laboratory.Vibrating Machine ALTEC Laboratory Equipments and ALTEC Laboratory Instruments Tenders.
