braking tail frames coupled with high torque hydraulic braking systems, braking tail frames offer complete control of downhill and regenerative conveyor systems. tail frame braking protects the loop take-up from the large braking belt tensions. braking tail frames are capable of producing up to 1200kw of braking power
head pulleys . the head pulley is located at the discharge point of the conveyor. it usually drives the conveyor and often has a larger diameter than other pulleys. for better traction, the head pulley is usually lagged (with either rubber or ceramic lagging material). tail and wing pulleys. the tail pulley is located at the loading end of the belt.
conveyor boot end fenner dunlop provides a complete proven range of boot end and tail end systems to receive material from multiple sources including shuttle cars and breaker feeders. our engineering team has the experience with complete conveyor system design which means our range of boot and tail ends are manufactured to cater for conveyor system dynamic belt loads that occur at the tail of the conveyor.
tail end: usually the end of a conveyor nearest loading point. tail pulley: a pulley mounted at the tail end of a conveyor, its purpose is to return the belt. take-up: the assembly of the necessary structural and mechanical parts which provide the means to adjust the length of belt and chain to compensate for stretch, shrinkage or wear and to maintain proper tension.
the tail pulley is located at the tail end of the conveyor and it turns freely. now a 'belt' can be put around the pulleys. the drive pulley turns and moves the belt around (and around, and around). but it is dangerous to have the belt hang down under the conveyor bed. so small rollers are put into the conveyor bed to hold up the belt.
tail pulley: the terminal pulley at the loading end of the conveyor. guard between the conveyor belt and the tail pulley for the in-running nip on the return run of the belt, considering nips between the pulley, and/or the belt and the framework of the conveyor. firm fencing is preferred for full isolation.
the inclusion of additional drive at tail end will need redesigning the conveyor i.e. new tensions at various points and consequent changes in forces acting at head end structure, tail end structure, take-up, pulleys, belt etc. then one has to see existing which items will remain unchanged and which items will change.
tail pulleys can utilize internal bearings or can be mounted in external bearings and are typically located at the end of the conveyor bed. tail pulleys commonly serve the purpose of a take-up pulley on conveyors of shorter lengths. snub pulley – a conveyor pulley used to increase belt wrap around a drive pulley, typically for the purpose of
the essential features of a belt conveyor system than be described with reference to. it consists of a driving pulley (1) at the head end and take up pulley (2) at the tail end, both being accommodated in a steel frame (3) an. endless belt (4) connects the two pulleys on both runs, and supported by suitable roller-type supports, called the idlers.
a head pulley is at the discharge end of a conveyor and in a simple conveyor is normally the drive pulley. a tail pulley is at the loading end of a conveyor and in a simple conveyor is normally the takeup pulley. a drum type welded steel pulley design with a solid hub was next introduced which appeared to be an improvement over the arm design.
the screw take-up on shorter belts is normally located at the tail end. 35-a 1400 mm width inclined belt conveyor has its head pulley at the elevation of 22 meter from ground, is used to convey 45 tph coal. the head pulley is coupled to motor of rpm 1450 through planetary gear box of efficiency 80%.
in general, powered conveyors employ head shafts and tail shafts where the head end provides the drive arrangement, and the tail end provides for adjustment of the chain or belt tension. conveyor controls can be simple on/off varieties, slightly more sophisticated soft-start types which cushion loads upon startup, or variable frequency drives that can control the speed, acceleration, etc.
for belt conveyors start at the tail end of the conveyor and work toward the head end of the unit. for belt driven live roller conveyor start at the head end of the conveyor and work toward the tail end of the unit. conveyor belting will track in the direction which is perpendicular to the axle of the tracking roller.
i pro rata the angle change / distance to specify its location, e.g. 35 - 0 degree / transition length [tl] = degrees / tl, rearranging, tl20 = degrees / tl * 20 degrees. i also require contractor to verify the installation with stringlines etc.
transition idlers are found at either end of the conveyor, adjacent to the head and tail pulleys.these idler sets comprise standard idler rolls however the bases into which these rolls are fitted, have a smaller troughing angle to that of the rest of the troughing idlers on the conveyor.the reason for this is that the conveyor belt is flat as it passes over the pulleys, under high tension.
horizontal screw take-up: the takeup mechanism maintains tension at the tail end of the conveyor to make sure that the conveyor belt is guided correctly as it returns to the top side. tail pulley: located near the feed chute, the tail pulley guides the conveyor belt
level and inclined conveyor receiving material at and near tail end, having vertical curve to incline, and discharging at head end. 3 4. level and inclined conveyor with chute. material received from bins too close to elevated head end to permit use of vertical curve.
m from the joint), towards head end of the conveyor belt. ii. to pull the loose belt, it should be clamped with a pair of angles (also called as pulling angles) at a distance of 3 to 5 m from the joint & towards tail end. iii. pull the belt from the pulling angles with the help of suitable chain blocks & slings. iv.
tail pulley is similar to the head end pulley of the conveying system, but the tail end pulley is not attached to a driving mechanism rather it moves with the movement of the conveyor belt which draws power from the head end pulley. the tail pulley is located at the tail end of the conveyor
usually the ultimate delivery end of a conveyor. ii. that part of a mining belt conveyor that includes the head section, a power unit, and, if required, the connecting section and a belt takeup. ref: nema, 2
the course covers the fundamentals of belt conveyor engineering including: belt width and velocity selection, conveyor power demand, belt sag, drive traction, drive types, brakes and holdbacks, information on conveyor arrangements, vertical curves and transitions, material trajectory calculations etc. plus belt, idler and pulley selection.
a troughed belt conveyor comprises an endless, rubberized flat belt (a) suspended between pulleys at either end and supported along its length by a number of rotating idler rollers (b). the belt is driven via one of the pulleys (usually the head pulley (c)) and the tension in the belt is maintained by using a sliding pulley (d) which is tied to a gravity take-up unit (e).
two drive pulleys (2 x 250kw and 1 x 250kw) at the conveyors head end at redcliff and the one drive (1 x 250kw) at the tail, are electronically controlled and provide a soft start, stop and an inspection speed of 1 m/s for easy belt maintenance. at full speed the belt travels
while drive assemblies can be installed at either the head or tail end of the conveyor, head end installation is typically preferred, as this “pulls” the conveyor belt, which is more effective than pushing. when space is limited, it is sometimes beneficial to install the assembly at a point along the conveyor (between the head and tail ends).
that is the tail end for belt conveyors and head end for belt driven live roller conveyor. observe direction of belt as it leaves end pulley/roller. if the belt moves toward one side of conveyor, adjust the snub roller just prior to the end unit by moving the end of the snub roller, on the side to which the belt is moving, toward the end unit.2
however, if the take-up is installed at the tail end, then the counterweight could be reduced to 55 kn. this is due to the fact that the return side belt tensions are increasing from the tail to head conveyor. therefore the 55 kn tail tension would result in the same 85 kn t2 tension.
first program: the design primarily delas with peoducing only the belt tensions at the head end, the motor power required and the belt safety factors based on the head end tensions. this program assumed the conveyor profile to be a straight line between the head and tail pulleys; and that all the materials to be carried is loaded at the tail.
