• Test sieves are woven wire or perforated metal pans that are used for sifting and filtration. 
• Test sieves are accurately constructed by placing wire cloth between two suppressed die formed frames. 
• Stainless steel or brass is generally used in the construction of both the frame and woven wire mesh.
• Sizes: 76, 100, 150, 200, 250, 300, 350, 400 mm, etc.
• Sieve frames stamped using 22 ga. Sheet metal.

• The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal distance of 800 mm from the centre of the table. 
• The table can be raised and allowed to fall freely on the stop by a cam which is connected to a motor and gearbox through a V-belt an pulleys.
• There is a projecting lug with a plane face on the upper face of the table beneath which is a stop with a rounded upper surface. 
• Locating pins are provided for mounting the mould compartments on the table. 
• The mould surmounted by the hopper can be clamped rigidly to the table.  
• The cam rotates at a rate of 60 Rev/Min. 
• A stroke counter fitted with micro-switch is provided which stops the machine after 60 Jolts. 
• Suitable for operation on 230 Volts, Single Phase, A.C. Supply. 
• A Digital Preset Counter can be supplied at an extra cost.
• Supplied complete with mould and hopper.

Spares and Accessories :
(1) Steel mould with base plate having three compartments each having 40 x 40 x 160 mm, internal dimensions.
(2) Apparatus for de-moulding the specimen.

Specification: 

• The instrument employs a friction free, accurate, double lever system, the load being applied by means of sliding weight on the top lever.
