screen working principle can be explained using the single deck screen and put it onto an inclined frame. the frame is mounted on springs. the vibration is generated from an unbalanced flywheel. a very erratic motion is developed when this wheel is rotated. you will find these simple screens in smaller operations and rock quarries where sizing isnt as critical. as the performance of this type of screen isnt good enough to meet the requirements of most mining operations two variations of this screen has been developed. see full list on 911metallurgist.com in the majority of cases the types of screen decks that you will be operating will be either the horizontal screen or the inclined vibrating screen. the names of these screens do not reflect the angle that the screens are on, they reflect the direction of the motion that is creating the vibration. see full list on 911metallurgist.com the counterbalance weight will alternately promote and retard the direction of vibration depending upon where within each revolution the weights come opposite each other. see full list on 911metallurgist.com eccentric shaft is used in the inclined vibrating screen. there is an advantage of using this method of vibration generation over the unbalanced flywheel method first mentioned. the vibration of an unbalanced flywheel is very violent. this causes mechanical failure and structural damage to occur. the four bearing system greatly reduces this problem.why these screens are vibrated is to ensure that the ore comes into contact will the screen. by vibrating the screen the rock will be bounced around on top of it. this means, that by the time that the rock has travelled the length of the screen, it will have had the opportunity of hitting the screen mesh at just the right angle to be able to penetrate through it. if the rock is small enough it will be removed from the circuit. the large rock will, of course, be taken to the next stage in the process. see full list on 911metallurgist.com the reason for using two decks is to increase the surface area that the ore has to come into contact with. the top deck will have bigger holes in the grid of the screen. the size of the ore that it will be removed will be larger than that on the bottom. only the small rock that is able to pass through the bottom screen will be removed from the circuit. in most cases the large rock that was on top of each screen will be mixed back together again. see full list on 911metallurgist.com the main cause of mechanical failure in screen decks is the vibration. even the frame, body and bearings are affected by this. the larger the screen the bigger the effect. the vibration will crystallize the molecular structure of the metal causing what is known as metal fatigue to develop. the first sign that an operator has indicating that the fatigue in the body of the screen deck is almost at a critical stage in its development are the hairline cracks that will appear around the vibrations point of origin. the bearings on the bigger screens have to be watched closer than most as they tend to fail suddenly. this is due to the vibration as well. see full list on 911metallurgist.com in plant design, it is usual to install a screen ahead of the secondary crusher to bypass any ore which has already been crushed small enough, and so to relieve it of unnecessary work. very close screening is not required and some sort of moving bar or ring grizzly can well be used, but the modern method is to employ for the purpose a heavyduty vibrating screen of the hummer type which has no external moving parts to wear out the vibrator is totally enclosed and the only part subjected to wear is the surface of the screen. the vibrating screen has rapidly come to the front as a leader in the sizing and dewatering of mining and industrial products. its almost un uses vary from the screening for size of crusher products to the accurate sizing of medicinal pellets. the vibrating screen is also used for wet sizing by operating the screen on an uphill slope, the lower end being under the surface of the liquid. see full list on 911metallurgist.com the type 70 screen is usually made 4 ft. wide and from 5 to 10 ft. in length. for the rough work described above it can be relied upon to give a capacity of 4 to 5 tons per square foot when screening to about ½ in. and set at a slope of 25 to 30 degrees to the horizontal. the type 50 vibrator requires about 2 h.p. for its operation. generally, manufacturers of screening units of one, two, or three decks specify the many dimensions that may be of concern to the user, including the total headroom required for screen angles of 1025° from the horizontal. very few manufacturers show in their screen specifications the capacity to expect in tph per square foot of screen area. if they do indicate capacities for different screen openings, the bases are that the feed be granular freeflowing material with a unit weight of 100 lb/cu ft. also the screen cloth will have 50% or more open area, 25% of total feed passing over the deck, 40% is half size, and screen efficiency is 90%. and all of those stipulations are for a onedeck unit with the deck at an 18° to 20° slope. see full list on 911metallurgist.com a general rule of thumb for good screening is that: the bed depth of material at the discharge end of a screen should never be over four times the size opening in the screen surface for material weighing 100 pounds per cubic foot or three times for material weighing 50 pounds per cubic foot. the feed end depth can be greater, particularly if the feed contains a large percentage of fines. other interrelated factors are: see full list on 911metallurgist.com vibration is produced on inclined screens by circular motion in a plane perpendicular to the screen with oneeighth to ½in. amplitude at 7001000 cycles per minute. the vibration lifts the material producing stratification. and with the screen on an incline, the material will cascade down the slope, introducing the probability that the particles will either pass through the screen openings or over their surface. the main feature of the vibrating screen is the patented mechanism. in operation, the screen shaft rotates on two eccentrically mounted bearings, and this eccentric motion is transmitted into the screen body, causing a true circular throw motion, the radius of which is equivalent to the radius of eccentricity on the eccentric portion of the shaft. the simplicity of this construction allows the screen to be manufactured with a light weight but sturdy mechanism which is low in initial cost, low in maintenance and power costs, and yet has a high, positive capacity. see full list on 911metallurgist.com screen capacity is dependent on the type, available area, and cleanliness of the screen and screenability of the aggregate. below is a general guide for determining screen capacity. the values may be used for dried aggregate where blinding (plugged screen openings), moisture buildup or other screening problems will not be encountered. in this table it is assumed that approximately 25% of the screen load is retained, for example, if the capacity of a screen is 100 tons/hr (tph) the approximate load on the screen would be 133 tph. see full list on 911metallurgist.com it is possible to not have enough material on a screen for it to be effective. for very small feed rates, the efficiency of a screen increases with increasing tonnage on the screen. the bed of oversize material on top of the marginal particlesstratification prevents them from bouncing around excessively, increases their number of attempts to get through the screen, and helps push them through. however, beyond an optimum point increasing tonnage on the screen causes a rather rapid decrease in the efficiency of the screen to serve its purpose. see full list on 911metallurgist.com these efficiency determinations necessitate taking a sample of the feed to the screen deck and one of the material that passes over the deck, that is, does not pass through it. these samples are subjected to sieve analysis tests to find the gradation of the materials. the results of these tests lead to the efficiencies. the equations for the screen efficiencies are as follows: see full list on 911metallurgist.com where: f0 and f1, from analysis of the feed to the screen deck and fp and fs are from analysis of the feed passing over or through the screen. examples to show how these equations are used will help. they can be illustrated by simple diagrams and arrows for the flow of material in the following cases: case 1where the amount of oversize material is small and so the stratification is poor and the screen efficiency is low. case 1where the oversize material is small: as was discussed with screen efficiencies, there will be some overs on the first passes that will contain undersize material but will not go through the screen. this material will continue recirculating until it passes through the screen. this is called the circulating load. by definition, circulating load equals the total feed to the crusher system with screens minus the new feed to the crusher. it is stated as a percentage of the new feed to the crusher. the equation for circulating load percentage is: to help understand this determination and the equation use, take the example of 200 tph original or new material to the crusher. assume 100% screen efficiency and 30% oversize in the crusher input. for the successive cycles of the circulating load: therefore, circulating load = new feed to crusher times r = 200 x 0.429 = 85.8 tph see full list on 911metallurgist.com case 2where the amount of oversize material is large promoting better stratification and screen efficiency. the patented design of dillon vibrating screens requires just two bearings instead of the four used in ordinary mechanical screens, resulting in simplicity of construction which cuts power cost in half for any screening jobreduces operating and maintenance costs. with this simplified, lighter weight construction all power is put to useful work thus, the screen can operate at higher speeds when desired, giving greater screening capacity at lower power cost. see full list on 911metallurgist.com the vibrating screen is available in single and multiple deck units for floor mounting or suspension. the side panels are equipped with flanges containing precision punched bolt holes so that an additional deck may be added in the future by merely bolting the new deck either on the top or the bottom of the original deck. the advantage of this feature is that added capacity is gained without purchasing a separate mechanism, since the mechanisms originally furnished are designed for this feature. a positive method of maintaining proper screen tension is employed, the method depending on the wire diameter involved. screen cloths are mounted on rubber covered camber bars, slightly arched for even distribution. see full list on 911metallurgist.com standard screens are furnished with suspension rod or cable assemblies, or floor mounting brackets. initial covering of standard steel screen cloth is included for separations down to 20 mesh. suspension frame, fine mesh wire, and dust enclosure are furnished at a slight additional cost. motor driven units include totallyenclosed, ballbearing motors. the vibrating screen can be driven from either side. the driven sheave is included on units furnished without the drive. see full list on 911metallurgist.com the unit consists of the freely suspended screen body and a shaft assembly carried by the screen body. near each end of the shaft, an eccentric portion is turned. the shaft is counterbalanced, by weighted flywheels, against the weight of the screen and loads that may be superimposed on it. when the shaft rotates, eccentric motion is transmitted from the eccentric portions, through the two bearings, to the screen frame. see full list on 911metallurgist.com 2021 buick envision looks to win buyers with style, ux more striking is the multilayered instrument panel that adds
