The Tripper Conveyor is designed to load individual bins by moving over the top of bins on the Layco Stationary Conveyor. The flow-through T. 13) Travelling tripper on conveyor Nos. .. Find out the design capacity for down line belt conveying system. . Therefore belt conveyor design capacity will be. A traveling tripper is a wheel mounted motorized equipment which moves on rails over a conveyor to stack material to intermediate/desired locations (bunkers or.

The reason for applying this strategy is straight-forward, belt tension increases as material is mined and loaded on the conveyor, to protect the physical integrity of the belt the tension regulator is only required to regulate i. Whether you need a reversing belt with discharges at both ends, filling trippre bins along the length of the conveyor, or you need to create a long continuous pile such as in filling a vonveyor storage building, FEECO has your material handling needs covered.

If a DC or AC drive can be used, the regenerative energy that results from regulating belt tension can be put back into the electric feeder mains as electric energy instead of into the mine shaft environment as heat energy.
Using a PI controller for the tension regulator G T s the asymptotic Bode plot shown in Figure 6 approximates the open loop transfer function Equation 9 from tripper tension reference to tension feedback. The PI regulator by itself cannot adequately compensate for extremely low frequency damped plant resonances such as those that occur in conveyor applications. Tripper discharge spouts are built to suit each installation. To facilitate a better understanding of the philosophy driving the proposed regulator structure a description of the clutch-type tension regulated tripper follows.
The use of regenerative trippre in the tripper can result in significant gripper savings, The following analysis provides an enlightening perspective on the potential for energy cost reduction using active regulation with drives as opposed to passive regulation with clutches.
To improve mine productivity, seam lengths and tonnage rates are increasing. Much like belt trippers, belt plows can release material on either side of the belt at pre-designated locations. While this increases consumption of fuel, it lessens time wasted in repairing damaged parts because desgin conveyor remains functional to some degree. A secondary clamp is locked to the rail as a double safety. The conveyors must be easily assembled and disassembled to facilitate quick turn around times when moving operations from a depleted seam to a fresh seam.
For that reason, newer model tripper conveyors have a smaller motor attached to the underside of the conveyor for every hundred yards desitn belt. Significant energy savings and more responsive tension regulation can be realized with this control topology if the tension regulator is designed with a stable and responsive closed tension loop. The following parameters were used in the model: As the belt passes over the upper pulley, the material is discharged from the belt into a collection chute.
Oklahoma State University, March The material is then diverted to one side or both sides of the belt for discharge, or back onto the belt if the desired discharge position is at the end of the conveyor.
Given that w R2 can be as low as 0. Experience has shown that considerable damping of the dominant low-frequency pole pair results directly from the conveyor belt construction and the substantial viscous, static and dynamic friction that is found in such systems.
A belt tripper can either be in a fixed position, or travel continuously at a constant speed for layered ttipper. To achieve this result, the lag should be set at approximately twice the crossover of the tension loop with the conveyor unloaded.
Additional cost reductions can be realized from the time saved when moving the ddesign. A Tripper Conveyor is a form of conveyor belt used in construction, mining, and other large-scale earth-moving businesses. Traveling Belt Trippers are independent units which travel on tracks discharging at selected points or allows continuous uniform stock-out of material along its travel. The basic concept of operation follows: This paper outlines a regulation scheme that addresses these problems and paves the way for cost effective underground mining conveyor solutions using AC or DC drives.
Implementing the tension regulator shown in the architecture described in Figure 3 with a PI only regulator will invariably result in an unstable or extremely de-tuned tension loop. Go to Navigation Go to Content. The Chantland team was invited to visit the site and after reviewing with the plant engineer and operations personnel, determined resign could design and build what they wanted.
In most mining conveyor applications the accumulator is located very close to the head pulley, therefore the mass of the belt between these trippwr sections can be neglected. Chantland MHS has built a variety of belt tripper designs over the conveyorr seventy years, most all of which have been motor driven, however a few years ago we began desing requests to replace trippers for belt conveyors powered by the main conveyor belt.
Figure 3 presents a single-line diagram of the proposed scheme.
This particular type of conveyor was designed to ferry debris, earth, rocks, etc, uphill. Click to Request a Quote or call us at Care should be taken to ensure the units are correct. Additional pole and zero pairs that occur at higher frequencies tend to cancel and do not contribute significantly to the dynamics of the tension control loop.
Our familiarity with a wide variety of materials allows us to accommodate even the toughest of material characteristics to provide an efficient material handling solution.
