This sieve shaker is designed to carry up to 7 sieves of 6 inch or 8 inch diameter. The 12 inch dia.sieves
can be used with the help of Adaptor. A 1/4 HP. motor through a reduction gear immersed in oil drives the
shaker. The sieve table dies not rotate but is inclined from the vertical axis and the direction of inclination
changes progressively in clockwise direction. If the stop-pin below the table is removed. the shaker can
have a rotary motion. In addition to this gyratory motion of the table, there is an upward and downward
movement ensuring that each square cm of the sieve is utilized. A pair of rods and a holder is supplied.
The holder can be fixed on the top of the upper most sieves, and thus the sieve set is firmly held. Suitable
for operation on 230 volts, 50 cycles single phase A.C. Supply.
Adaptor for 30cm dia test sieves can be fitted in above.
FOR 45 CM DIA SIEVES
This sieve shaker is designed to carry up to 7 sieves of 18" diameter. The shaker is driven by a 1/2
H.P.Electric Motor through a reduction gear. The sieve table does not rotate but is inclined from the
vertical axis and the direction of inclination changes progressively in the clockwise direction, in addition to
this gyratory motion of the table, there is and upward and downward movement at a frequency of about
270 vibration per minutes ensuring that each square inch of the sieve is utilised. The whole gear
mechanism runs in an oil bath, without test sieves or time switch. Suitable for operation from 220 Volts 50
cycles A.C. supply.
OPTIONAL EXTRA:
• DIGITAL Time switch 0-99 minutes for above
• MECHANICAL Time switch 0-60 minutes for above
GENERAL DESCRIPTION AND SPECIFICATION:
The apparatus comprise of a slump cone with handles made of mild steel sheet, a chrome plated steel
tamping rod of 16 mm diameter X 600 mm long, rounded off at one end, with a scale marked on it and a
steel base plate with a carrying handle.
The mould for the test specimen will be in the form of frustum of a cone having the following internal
dimensions as follows.
• Dimensions Cm
• Bottom diameter 20
• Top diameter 10
• Height 30
The Cone is constructed of metal of at least 1.6 mm thickness and the top and bottom are open and at
right angles to the axis of the cone. The mould have a smooth internal surface and provided with suitable
foot pieces to a base plate and also handles to facilitate lifting it from the moulded concrete test specimen
in a vertical direction as required by the test. The base plate is provided with cleats & swivel handle.
