middling products are discharged into bucket elevators or equivalent discharge devices via the jig discharge gates and the chamber bottom outlets. The design of all these discharge devices focuses on aspects of wear and there- fore all outlets are built with replaceable, stainless steel insert boxes.
May 01, 2017· The transfer function of the discharge system in a jig can be approximated by a nonlinear integrating element with saturation determined by the height of the coal layer placed above the upper product overflow gate.
When inputs compressed air, the water in jig washer is forced to ascend; after the compressed air discharged from air chamber, the water level descends automatically, the pulsating flow is formed when water in jig room goes through screen panel up and down, R.O.M is layered according to density under the function of pulsating flow, and is divided into 4 kinds of products by discharge mechanism, coal

LUMP ORE TWO CUT, 3 PRODUCTS (CONCENTRATE/MIDDLING/REJECT) JIG Here the heavy fractions of the first two chambers are producing the concentrate, discharged through the first discharge gate system into the first dewatering bucket elevator (Fig. 2). The heavy fraction of the third chamber is a middling product which can be crushed and fed to a fine
discharge jig pipe Prior art date 1908-08-06 Legal status (The legal status is an assumption and is not a legal conclusion. The overflow from the raw coal screen is treated in a Baum jig, which produces two product streams (a coarse and a middling fraction) and a refuse stream. The product streams are dewatered and sent to the clean coal
A customary practice, for instance, is to draw a middling product from a set of jigs and after dewatering run it through a crusher directly to the tables. Such procedure nearly always provides a variable feed for the tables whereas a constant feed could be obtained by dropping the discharge from the crusher into a bin and having mechanical feeders between the bin and the tables.
methods for measuring the separation density in a jig could be observed in recent years. The first attempt to use a radiometric density meter to adjust the bot-tom product discharge was conducted by D. Bartelt [1] in 1964. Bartelt achieved very positive results in the application of the density meter in a control sys-
Jun 01, 2016· This applies to coal separation jig machines in which stratification of coal grains of varied density takes place in a pulsating coal/water bed. The jig separates the coal into two streams based on their relative densities. These two streams are the coal product with either a discard or a middling product. 2. Technological objective
Jan 01, 2015· This applies to technological systems of coal separation in a jig where stratification of coal grains due to their densities is performed in a pulsating coal/water bed. The jig separates the coal into two streams based on relative density. These two streams are the coal product with either a discard or a middling product.

A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products. A jig is often confused with a fixture; a fixture holds the work in a fixed location.A device that does both functions (holding the work and guiding a tool) is called a jig.
