Flow tables are used for
different purposes. They can be used to determine the flow of cement and
concrete. They can also be used to determine the workability of building
limes and for measuring the consistency of Pozzolanas and also cement
mortar and hydrated lime.
Types
Depending on their working principle, Flow Tables are generally of two
types:
- Hand Operated Flow Table
- This type consists of finely machined brass or steel table
top of about 30 inch diameter.
- There are integral cast ribs designed for support and
strength of table top.
- The stand of the table is fabricated out of cast iron and is
of sturdy construction.
- There are holes for mounting in foundations that are drilled
in the base plate.
- There is a ground and hardened steel cam, which is designed
to lift and drop the table by 12.5 mm.
- Provided with hand wheel, which makes operation of the table
simple and easy.
- Provided with one conical mould with handles of different
specifications.
- Also provided with a tamping rod.
- Motorized Flow Table
Specifications of the motorised flow table are same as that of hand
operated. But this type is fitted with a electric motor, which is
connected to the cam shaft through a reduction gear to give
approximately 100 rpm. It is electrically operated to raise and drop
the table top approximately 15 times in 15 seconds. It is suitable
for operation on 230 Volts, 50 cycles A.C. supply.
