Vibrating Table Manufacturer,Supplier and Exporter in India
Product Code : EL-WT-8785
Jlab Export is a leading Vibrating Table Manufacturer,and suppliers in India
This table shakes freshly filled concrete cube moulds from below, so the concrete settles and its trapped air escapes without hand rodding. The 500 x 500 mm top has raised edges and carries up to 140 kg. A variable pitch pulley sets the frequency anywhere from 2600 to 3600 rpm, while the amplitude stays fixed. A starter switch turns the table on and off.

Concrete Cube Practicals on the Table
A typical concrete practical starts with a trial mix in the Laboratory Concrete Mixer and a workability check with the Slump Test Apparatus. Students oil the Cube Moulds, set them on the table and fill them in layers, vibrating each layer until air bubbles stop rising and the surface closes.
After curing, the cubes are crushed on the Compression Testing Machine. Casting one set on the table and one set by hand rodding shows what compaction does to strength. Students can also vibrate a stiff mix at the low and the high end of the frequency range and compare the finished faces of the cubes.
Frequently Asked Questions
How long should each layer be vibrated?
Vibrate until large air bubbles stop rising and a thin film of mortar shows on top. A stiff mix needs longer than a wet one. Stop once the surface looks closed, because running much longer drives the heavy aggregate down and brings water to the top.
Can the vibration frequency be changed?
Yes. The variable pitch pulley alters the drive ratio, so the frequency can be set anywhere between 2600 and 3600 rpm. The amplitude is fixed by the machine, so speed is the one setting the operator changes for different mixes.
How many cube moulds fit on the table?
That depends on the mould size. The 500 x 500 mm top takes as many moulds as fit inside its raised edge. The moulds and fresh concrete together must stay within the 140 kg maximum load. Weigh one filled mould to work out how many can go on at once.
Should I choose this table or a poker vibrator?
The table vibrates the whole mould from outside, which suits small specimens such as cubes. A poker is pushed into the concrete and works from inside, which suits beams, cylinders and large batches. Many labs keep both and use the Poker Vibrator for the larger moulds.
How is it different from a mortar cube vibrating machine?
The Mortar Cube Vibrating Machine holds one small mould of cement mortar and runs at a much higher fixed frequency. This table takes several concrete cube moulds on an open top and lets the operator set the frequency within its range.
