Jig separator 1. Crushing: The large pieces of coal are sent to the jaw crusher by the vibrating feeder for rough crushing, and the coarsely crushed materials are transported by the conveyor to the impact crusher. The impact crusher is suitable for medium or fine crushing in order to further dissociate clean coal. 2.
Ensure Adequate Air Flow A properly functioning pneumatic system requires a proper supply of plant air. Without adequate plant air, the pressure will sag during use, especially when the machine requires …

Rugged, durable, and versatile Deca pneumatic vibrators offer some of the most affordable units available, to provide cost-effective solutions even in applications where electric or hydraulic power is not practical. Our vibrators feature a low up-front cost and relatively low maintenance requirements over time.
A Batac jig of this size will require the following: Water requirements: 5,300 gallons per minute at 12 psi for the underwater and water with the feed, the latter being generally about one-third of the requirement. Operating air: 130 m³ or 4,590 cfm at 7 psi. Compressed air for controls: 2 m³ or 70 cfm at 88 psi.
Three monitoring and control systems shown in Fig. 7 were tested in the coal preparation plant "Murcki" over a period of two years between 2013 and 2015. ... The aim of this study was to look into particle stratification in a pilot-scale pneumatic jig when varying the particle size and the range of the particle size distribution in ternary ...
This paper aims to provide insights into the factors contributing to the efficiency of separation of solids particles in pneumatic jigging. A batch pneumatic jig was constructed at the University of Nottingham, UK, for solid waste recycling. Synthetic materials (density tracers), colour coded for density, were used as the bed materials in a …
The Paddock pneumatic ore separator is a jig, in which air is used instead of the fluid more commonly employed—water. Like the water jig, it consists of an inclined sieve, over which the crushed ore is passed, …
Today with the advent of modern fine coal jigs in the United States, its place was moved from the coarse to the intermediate coal circuit, the 3/8″ x 100 mesh. Recent theoretical performance and economic …
In this study, -4 mm coal fines from Soma region of Turkey with the ash content of 31-32 % were treated through air jig employing the pulsation effect and the aerodynamic separators which...
The Paddock pneumatic ore separator is a jig, in which air is used instead of the fluid more commonly employed—water. Like the water jig, it consists of an inclined sieve, over which the crushed ore is passed, and through which the air is blown into the ore.

The RAW air type jig is one of the precursors of air jigs currently used. Its construction is based on box equipped with steel sieve arranged in a staircase-like way. Each subsequent sieve is thinner than sieve before (3 parts of sieves, together). The box of air jig is located on steel construction by spring levers (as a result the box shakes).
The jig plant consists of eight modules with three jigs each: the Coarse Jig (-25 mm +8 mm), Medium Jig (-8 mm +3 mm), and Fine Jig (-3 mm +1 mm). The feed to the plant is spread evenly over the width of the …
In general, the pneumatic jigging movement depends on two important factors which are airflow rate and pulse rate. The former lifts the bed, and the latter creates intermittent air current....
Application of pneumatic separators in coal beneficiation is increasing rapidly over the last decade primarily due to their low capital and operating costs, and waste handling problems associated with traditional wet processing methods.
In this study, -4 mm coal fines from Soma region of Turkey with the ash content of 31-32 % were treated through air jig employing the pulsation effect and the …
The Batac jig uses flat discs which are electronically and pneumatically controlled. These valves, both for inlet and outlet of air, …

A properly functioning pneumatic system requires a proper supply of plant air. Without adequate plant air, the pressure will sag during use, especially when the machine requires high air flow during operation. …
Reduced to its simplest terms, the air-pulsated jig essentially consists of two separate mechanisms: one of jigging which occurs in …
Pneumatic valve actuators are powered with air or gas. The air pressure acts as a piston to create linear force to close and open the valve. Power plants have traditionally used pneumatic...
