dewatering screen coal washing nov 26, 2019 · the coal vibration dewatering screen solves the problem of a low coal washing rate. the vibration dewatering screen is an efficient washing and screening equipment. compared with other washing equipment, this equipment has a high degree of cleanliness, less material loss, less energy consumption, and lower investment costs. dewatering screen 911metallurgistthe test circuit used in the mediumdrainage tests is illustrated in figure 1. a 26inch by 8foot horizontal vibrating screen divided longitudinally was arranged so that one side could be fed with the oversize product of a sieve bend. the other side was fitted with a scalping deck made by attaching the screen surface of the sieve bend directly to the feed end of the vibrating screen. when desired, the sieve bend could be bypassed so only the vibrating screen was in use. thus, with this combination the vibrating screen alone, the vibrating screen fitted with the scalping deck, or the vibrating screen operating in tandem with the sieve bend could be used in testing. all screen underflows passed to a sumpagitator where magnetite or water was added as needed to maintain medium density, then recirculated through the system via the head tank where the coal or refuse was added. all screen surfaces (vibrating screen, sieve bend, and scalping deck) were 0.5mm wedge wire. in all tests, onl see full list on 911metallurgist scalpingdeck position one of the first steps of the investigation was to determine the influence of the inclination at which the scalping deck was mounted on the vibrating screen. tests were conducted to determine the performance of the scalping deck at two angles of inclinationone with the feed end vertical and the other with the discharge end horizontal. both washed coal and refuse, with medium of appropriate specific gravity, were used in these tests. when draining washed coal, the angle of inclination was uni size composition two refuse products, both of ¼inch to 0.5mm size but one much coarser than the other, were tested under similar operating conditions. the only samples collected were those of the feed and discharge of the scalping deck. the amount of magnetite retained in the discharge of the scalping deck varied in proportion to the amount of 14 to 28mesh material in the feeda fourf increase in the percentage of this size caused a fourf increase in the amount of magnetite retained (table 3). th specific gravity of medium the various screen combinations were used in a series of drainage tests in which the specific gravity of the medium was the principal variable. specific gravity was varied from 1.80 to 2.20, which is approximately the range encountered in cyclone underflow. these tests were made at a feed rate of 7.5 tph/ft of coal (or refuse). when only the vibrating screen was used (fig. 2), the amount of magnetite in the screen product increased rapidly with increase in the specific gravity of medium. with see full list on 911metallurgist screen capacity the first step in the investigation of dewatering was to establish the capacity of the vibrating screen when used alone. in these tests a watertocoal ratio of 3 to 1, simulating the washedcoal product of concentrating tables, was used. at a feed rate of 5 tph/ft of screen width, a pool of free water on top of the bed of coal rapidly progressed all the way down to the discharge end of the screen. the screen was obviously overloaded. at 3 tph/ft dewatering appeared to be satisfactory at firs moisture reduction because the performance of dewatering screens is influenced by the amount of water in the feed, a series of tests was made at various watertocoal ratios, using the several screens singularly and in combination. results of these tests, which were made at a feed rate of 8 tph/ft of screen width, are shown in figure 5. when the feed contained about 35 percent solids, the vibrating screen was able to reduce the moisture content to about 36 percent. as the feed became wetter, the vibrating scree recovery of fine coal the loss of fine coal that inevitably occurs on dewatering screens is a function of feed rate and of the moisture content of the feed. when the feed to the vibrating screen was reduced to 1.5 tph/ft to achieve equilibrium dewatering conditions (in treating a feed of 25 percent solids), only 15 percent of the coal finer than 28mesh was recovered in the screen oversize (table 5), when the scalping deck was added to the vibrating screen and the feed rate increased to 8 tph/ft, the recovery of m see full list on 911metallurgist the improvement in both densemedium drainage and dewatering that occurred when the sieve bend or the scalping deck was used in conjunction with the vibrating screen is attributed to two factors. first, these auxiliary devices eliminated enough of the nearaperture size particles to substantially eliminate blinding of the vibrating screen. thus the degree of improvement that can be expected because of this factor depends on the size shape characteristics of the coal. the two coals used in this investigation were both prone to cause blinding, and therefore the improvement observed was substantial. with coals of more favorable sizeshape composition, the degree of improvement would be less. the second factor responsible for the improvement observed when the sieve bend or scalping deck was used is that either of them removed a substantial proportion of the liquid, thus relieving the load on the vibrating screen. under most of the test conditions employed, these auxiliary devices remov see full list on 911metallurgist dewatering screen xinxiang hengyu machinery equipment co china dewatering screen catalog of mining dewatering machine washing
