Gyratory Sieve Shaker carries upto 7 sieves of 150mm or 200mm diameter. The shaker is driven by a ¼ h.p (motor through a reduction a reduction gear immersed in oil. The sieve table does not rotate but is inclined from the vertical axis and the direction of inclination changes progressively in a 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 holder are supplied. The holder can be fixed on the top of the uppermost sieves and thus the sieve set is firmly held. Suitable for operation on 230 Volts, 50 cycles single phase, A.C. Supply.

Proving Rings are used for load meassurements and are used in the outfits of a number of soil/cement & bitumen testing equipments like Direct Shear Apparatus. Triaxial
Shear test Apparatus, CBR Test. Unconfined Test, Marshall
Test etc. They are made out of special steel carefully forged to give maximum strength and machined to give highest sensitivity combined with stability to ensure long life and accuracy
When compressive or tensile load is applied within the elastic range, the proving rings get temporarily deformed.
This deformation is measured by a sensitive
dial gauge fixed co-axially at the centre of the proving ring
The dial readings thus obtained versus load applied enable the operator to findout unknown load,, just by noting the dial gauge reading for the unknown load.
The proving rings have hogh elasticity and on removing load they regain the orginal shape provided they are loaded in their elastic limits.
The dial gauge and plunger anvil are mounted on brackets clamped to the ring body. The dial gauge is held perfectly rigid without the remotest chance of shifting due to inadvertent shocks or pressure exerted on it. The dial gauge plunger rests on an adjustable anvil.
Proving Rings from 50 kg to, 1,00,000 kg capacity provided with 1/2 inch B.S.F. female threads. Loading bossess and a loading ball nipple and steel ball are supplied with each rings
Rings of capacity over 25000kgf (or 25 tonnes) are not thus threaded.
Each ring is individually calibrated and supplied with works calibration charts and a carrying case.
Calibration charts from Standard Laboratories for the proving rings ordered are also available at extra cost. All Proving rings are Integrall type. Integral type compressicve Proving Rings of different capacities from 50 kgf to 200000 kgf are available

Product Details:

Consists of a  torque head adjustable in height by means of a lead screw rotated by a drive wheel to enable the vane to be lowered into the specimen. Rotation of the vane is by means of a hand wheel which operates a worm gear arrangement turning the upper end of a calibrated torsion spring,  Vane dia,  rod dia,  vane size & vane height are as per IS specification.
The Vane shaft is attached through the hollow upper shaft to resettable pointer,  which indicates the angle of torque on a dial graduated in degress.  The dial reading multiplied by spring factory gives the torque.  A container for soil sample is also supplied,  and a sampiling tube of 38mm I.D. & 150 mm long can also be used as container 6 kgcm,  and 8 kg cm. Complete as above in a wooden carrying case.

For collecting undisturbed samples of 38 mm dia for Triaxial shear strength and Unconfined Compressive strength either straight from the field or from a sample of large diameter. The wall thickness is maintained approximately 1.6mm with an area ratio approximately 17 percent.  Both relieved and unrelieved sampling tubes are available.  In the relieved type of tube, the internal diameter is relieved by about 0.5mm of tube, the internal diameter is relieved by about 0.5mm (Inside cllearance 2%, beyond approx. 19 mm length from the cutting edge of the tube, this is most suitable for highly cohesive soils. In the unrelieved type, the internal diameter is uniform throught, thiis type is most suitable for soils of low cohesion. These 38mm dia tubes are available in different lengths.

For determining the Liquid Limit of soils. This is specially useful to obtain reliable and accurate results for those soils which have low plasticity index. The percenetage moisture contents determined when a cone with half angle of 15 - 30 minutes under a total sliding weight of 148 gm penetrates 25 mm gives the Liquid Limit.
Consists of a vertical pillar mounted on a base provided with leveling screw The head together with dial gauge rod and cone (or needle) slides on a pillar and can be clamped at required height. A rack and pinion and pointer assembly provides adjustment of needle or cone tip to sample.  It incorporates a slipping clutch mechanism which make reading of penetration, and subsequesnt restting a simple and accurate operation
The dial is graduated in 400 1/10th mm sub-divisions,  and the red needle pointer against black figures makes for easy reading.
Suplied complete with 50 mm dia x 50 mm high cup complete with stainless steel cone  50 mm x 40mm dia high made  of gunmetal.
