coal jigging is a process pulsation

Jigging - an overview ScienceDirect Topics

One of the oldest forms of coarse coal cleaning is jigging. Jigging is the process of particle stratification due to alternate expansion and compaction of a bed of particles by a vertical pulsating fluid flow. A single jigging vessel can treat large particles (up to 200 mm) at capacities approaching 680 tonnes (750 tons) per hour. Common versions include the baum and batac designs. The baum ...

Simulation of the Jigging Process: Coal Preparation: Vol ...

08/02/2007  Jigging is one of the most important separation methods used in coal preparation plants. The process is very complicated and is affected by many factors. In order to estimate and predict the optimum production performance, the process is modelled as a Markov technique and simulations are carried out. The Markov technique is a stochastic process.

Influence of Pulsation Frequency in Iron Oxide Jigging

coal preparation because of its high separation precision, cost-effectiveness and high throughput rate. A jig is a gravity separator that uses pulsation (repeated expansion and contraction of a vertical bed of particles) of water. The result of this movement is the bed stratification, where the materials density splits in ascending order from the top to the bottom [4][5]. MMME 121-2 Jigs uses ...

Jig concentrators - Wikipedia

Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are ...
