Laboratory Ro-Tap Sieve Shaker

Product Details:
  • Applications: laboratory testing of particle size and size distribution in samples of solid materials
  • Motion: Circular

Laboratory Ro-Tap Sieve Shaker are used for laboratory testing of particle size and size distribution in samples of solid materials. Used for soils, geological materials, alloys, and a host of other solid sample types that have individual particle sizes of from over 5" down to 20 microns. Testing is accomplished by stacking a set of sieves of various sizes on top of each other, where the larger-hole sieves are on top and smaller-hole sieves are on bottom, in decreasing order. A solid pan is at the bottom to catch all sample particles that can pass through the smallest sieve's openings. The ro-tap sieve shaker is an apparatus that holds the entire stack of testing sieves, mechanically shaking / rotating them in a circular motion and tapping the top of the stack at the same time (this, rotap). These actions help the various sized particles to be able to move through the stack of sieves until they rest on a sieve whose openings are too small for them to pass through. After a designated period of time of this mechanical shaking/tapping, the screens are removed from the ro-tap, and each sieves contents are weighed up and recorded individually, from this data set, the % retained on each sieve is used to classify the size fractions present in the sample.

The materials of construction of grinding media depends up on the type of samples to be grind for geological ores & minerals - hardened steel grinding media, for alloys - tungsten carbide lined grinding media for coal & coke - tungsten carbide coated grinding media.

Laboratory Mineral Jig

Approx Price: Rs 92,000 / Unit

Jigging is the process of separating the particles of different specific gravity, size and shape by introducing them on screen though which a fluid is made to pulsate alternately. It is consists of a rectangular open top container. The bottom of the container is either a screen or a perforated surface which supports the bed of the solids. Pulsion and suction strocks of water through the screen are given by means of a reciprocating piston. During the pulsion stroke, solid bed is opened and the particles are lifted. The particles settle into more homogeneous layer during the suction stroke. By repeated pulsoin and suction stroke, a complete stratification is achieved with the heavy particles at the bottom and lighter particles above them.

The following three effects contributes to the stratification in Jig:-

  • Hindered settling classification.
  • Differential acceleration at the beginning of fall.
  • Consolidation trickling at the end of the fall.
