Small Laboratory Jaw Crusher
Item code: EBTE-20

Small Laboratory Jaw Crusher The laboratory crusher is designed to speed up the crushing of aggregates, ores, minerals, coal, coke, chemicals and other similar materials. It is compact and of rugged construction for general laboratory or small pilot plant operation. Two jaws of manganese steel are provided in the jaw crusher. The moveable jaw produces two blows for every revolution. Thus reducing over sizing to a minimum. A combination of forward and downward stroked with a rocking action exerts pressure on the coarser material, yet permits the finished material to pass through the jaws. A hopper is provided at the top for feeding materials. The smooth jaws ensure a uniform product and easy cleaning is possible.

• Jaw size : 100 x150 mm Max.
• Size of fed : 50 mm (approx)

Static Cone Penetrometer, 30KN (300KGF) Capacity,Hand Operated
Item code: ESTE-70

The drive is by means of a rack and pinion manually through a gearing arrangement. The gear box and pinion are fixed on two handles, sprockets and chain arrangement. The movement of the rack is guided by a bracket ( attached to the rack) and two pillars. The penetration resistance i.e. the pressure is indicated on hydraulic gauges through a hydraulic measuring head. Two pressure gauges of 15cm dia dial and 2 capacities 0-160kg/cm are provided. An automatic cut-off valve, to protect the low capacity gauge from being overloaded is provided. The 2 valve can be adjusted and locked at desirable values between 20 to 60cm . A provision is made to anchor the unit to the ground (with the help of four anchors supplied with the unit) and there is a provision for lateral 2 movement of the unit so that subsequent tests could be performed without shifting the entire anchorage. A 10cm penetration cone with friction jacket is provided along with fifteen mantle tubes (non-uniform having an effective length of 1 m each with sounding rods for finding out the cone (point) resistance or jacket friction.

Shrinkage Limit Apparatus :

Item code: ESTE-131

Shrinkage Limit is the maximum water content at which a reduction in water content does not cause an appreciable reduction in volume of the soil mass. At shrinkage limit, on further reduction in water, air enters into the voids of soils and thus keeps the volume constant. The apparatus can be used to determine shrinkage limit and to calculate other shrinkage factors like shrinkage ratio, shrinkage index and volumetric shrinkage.

Salient Features Specifications :

Set consists of one each :

1. Porcelain evaporating Dish.
2. Shrinkage Dish.
3. Glass Cup.
4. Perspex plate with three metal prongs.
5. Perspex plate.
6. Flexible spatula.
