Description

We offer concentrating plant which is based the principle of countercurrent separation with separation in an aqueous medium. DESCRIPTION enrichment plant using coals with steeply inclined separators. BACKGROUND 1. Countercurrent separation gravitational separators differ in their nature and material of the concentrating principle of the mode of regulation. Thus, despite the differences in the structural features of the separators, they realized the generic principles is to increase the separation efficiency due to recirculation of a certain part of the concentrating material within the working area. In all countercurrent gravity separators starting material is divided into two products: - concentrate and waste. Steeply inclined separators (hereinafter SPS) are intended for enrichment of coal and other minerals, it has a high thermal performance, small size, easy and safe to use. The small residence time of the material in the shared work area and ease of adjustment allows separation of the density of their use for coal beneficiation with razmokaet inclusions. CND is a body of rectangular or trapezoidal in length from 3 to 5 meters and with a cross of 0,15m2 to 075 m2. At the top of the section of the channel in the classic version, there are two adjustable deck with baffles arranged across the body section of the device. Above chute - Concentrate deck lower chute - breed in the central portion of the apparatus having a charging nozzle located in the upper part of the hopper, in which the starting raw coal arrives. In the working position the machine is set at an angle of 46 - 52o to the horizontal plane, in this case the loading duct has a vertical arrangement. Position December channel can be varied by independent adjusters disposed on the top cover portion of the concentrate and rock separator. Each deck has an attachment to the adjusting mechanisms at two points on the axes, which ensures their setting in operative position at a right angle to the lower plane of the machine housing. In extreme deck along the length of the points connected with lids rubber collars, that prevents large particles of coal and rock outside the space between the decks and lids. The lower part of the separator by a flange and a transition section connected to the elevator dewatering in case of enrichment grade 6 - 13mm. Or rotary discharger, in the case of enrichment 0 - 6mm class. PRINCIPLE OF OPERATION SOS. The starting raw coal enrichment to be continuously supplied by the loading chute to the central part of the apparatus. Simultaneously the lower part of the channel separator via a transition section arrives at a predetermined speed in the water separator steeply inclined transporting the separated components is performed in different directions due hydraulically forces created ascending flow of separation medium and the forces of gravity. Zones baffles are portions of locally increasing flow rate, however represent repetitive zone loosening material. Furthermore, partitions on the decks is increased flow resistance in the upper part of the canal and create therein a variable length and the width of the flow velocity field that provides the most favorable conditions for the separation of coal and rock in the working area. Heavy oils fall to the bottom layer, moving down towards the water flow further flows through the transition section into the dewatering silo, or in case of small class enrichment and sludge - through a rotary unloader at high crashing. Light ends are carried upwards through a drain separator threshold where subsequently fall on arcuate sieve preliminary water removal and dewatering screen. Efficiency of enrichment depends on a number of fixed and variable parameters. By constant parameters include the angle of the separator body and the position of the movable December. Variables (operational) parameter is the flow rate of water supplied to the lower part of the apparatus, as well as, if necessary, into the hopper. December position of the moving orifice defines a working channel in the concentrate and rock separator parts. From their position depends on the bandwidth (capacity) system, high - quality performance of the separation process, as well as the relative water consumption for processing the raw material at optimum load. Thus formed counter separation processes. Transport streams separation products are moving within the working area to specify the hydrodynamic resistance of their relative movement. When this stream of light fractions is co - current separating medium, and the flow of heavy fractions - counter. When properly chosen for a given feed - through sections of rock and concentrates ratio separator channels and stable feeding concentrating material efficiency KNS separators when enriched even high - ash coal in a single step Epm = 120 - 140 kg / m3 at densities of separation 1700 - 1800 kg / m3. The density of the separation in the separators KNS varies between 1400 - 2000 kg / m3 At the present time in Ukraine has one enrichment facility mounted in 2016 at the mine complex technological 1/3 "Novogrodovskaya" ON "Selidovugol". CND efficiency separators with high - ash coals even enrichment in one step Epm = 120 - 140 kg / m3 at a separation density 1700 - 1800 kg / m3. The density of the separation in the separators KNS varies between 1400 - 2000 kg / m3 At the present time in Ukraine has one enrichment facility mounted in 2016 at the mine complex technological 1/3 "Novogrodovskaya" ON "Selidovugol".
