Modelling of particle stratification in jigs by the discrete element ...

Abstract. This paper attempts to review the theories and mathematical models which have been advanced to explain the jigging process. The existing literature on mathematical modelling and quantitative analysis of jigging reveal that very little is known about the stratification of particles in a jig bed. It is realized that a microscopic model ...

Coal preparation plant Wikipedia

A coal preparation plant ( CPP; also known as a coal handling and preparation plant ( CHPP ), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into ...

Jigging: A Review of Fundamentals and Future Directions MDPI

For centuries, jigging has been a workhorse of the mineral processing industry. Recently, it has also found its way into the recycling industry, and the increasing concerns related to water usage has led to a renewed interest in dry jigging. However, the current scenario of increasing ore complexity and the advent of smart sensor technologies, such as sensorbased sorting (SBS), has ...

PDF Jigging: A Review of Fundamentals and Future Directions

Introduction Jigging is one of the oldest methods of ore treatment and remains one of the workhorses of the mining industry. Until recently, it was, together with dense medium separation (DMS), the main (when not the only) choice for preconcentration and concentration of coarsesized ores and coals.

Efficacy of Pilot Scale Batac Jig on LVC Coal Utilization for Coke ...

The focus of present research is to see the effectiveness of Pilot scale Batac jig for beneficiation of coarse (− 13 + 1 mm) low volatile coking coal from Jharia through a series experimentation wherein appropriate diverse process parameters were exploited for definitive study. The feed coal properties were measured in terms of proximate and ultimate analysis. The gross calorific value was ...

Mineral Beneficiation and Processing of Coal | SpringerLink

Baum and Batac jigs are two types of airpulsated jigs, which have found extensive applications in the coal industry. Stratification of particles in a Baum jig is caused due to the effect of pressurized air into the jig water system, which in turn causes alternate pulsation and suction of coal particles fed over the ragging bed.

Definition of Baum jig

Definition of Baum jig. A washbox in which the pulsating motion is produced by the intermittent admission of compressed air to the surface of the water following a principle introduced by Baum. Also called Baum box; Baumtype washbox. See Also: jig.

Role of water velocity for efficient jigging of iron ore

Jigging is a densityseparation process which is widely used to separate heavier particles from the lighter ones. It is used for beneficiation of ore minerals as well as washing of coal. In its class it is by far the simplest yet a robust mechanical device that can treat comparatively larger size feed materials at higher throughputs.
