Ash Grove Cement to receive longest pivoting pan conveyor
The delivery of a 232 meters long pivoting pan conveyor via its US subsidiary, to Ash Grove Foreman (USA) marks a new length record set by AUMUND Fördertechnik in Rheinberg, Germany. The pivoting pan conveyor forms part of a delivery package for a new line and has been designed for the transport of clinker with a conveying capacity of up to 272 mt/h. The Ash Grove Cement Company founded in 1882 and headquartered in Kansas, operates cement plants in the South Western US states. With a yearly production of 9 million tons the company is one of the leading cement producers in the USA. The cement produced by Ash Grove is utilized for main infrastructure and housing projects.
AUMUND pivoting pan conveyors (type SPB) provide a proven solution, when more than two clinker silos or several mill hoppers are to be fed. The conveyor’s special feature is that it allows intermediate discharge, wherever discharge stations are located along its entire conveying path. Thus, various tasks of material distribution may be realized in a single conveyor.
A special pan pivoting system in the area of the drive and tension station enables the pan to be upright in the upper and lower run, and allow simultaneous material transport in both runs.
The pivoting pan conveyor for Ash Grove will transport cement clinker in both directions in a single conveyor, a two-way chute will feed the material in the lower run onto the conveyor. The upper run is fed by a standard feeding chute. The material transport which may be performed simultaneously in upper and lower run allows clinker to be transported to and from the new plant to the old line with a single conveyor.
It would e.g. be possible to feed the material in the upper run and subsequently transfer it via an upper run discharge station into the lower run. The material distribution may be effected via discharge stations in the lower run into clinker silos or mill hoppers..
In the past, AUMUND implemented most difficult transport solutions by means of the pivoting pan conveyor. For instance, cement clinker was fed in the lower run into a silo, while the upper run transported gypsum to another hopper at the same time.
Sensor-monitored and computer-aided remote control of the discharge stations as well as automatic feeding of silos form part of the standard equipment. Optimum material distribution is achieved by co-operative planning. Different constructional heights may be compensated by chute systems. Decisive aspects for the design of the pivoting pan conveyor are the requested conveying capacity, the conveyor speed, the bulk weight of the material and the filling rate. In the past, AUMUND already implemented conveyors with capacities of over 600 t/h.
The conveying elements of the pivoting pan conveyor consist of approx. 1 m long pans, which have formed sides and overlap by approx. 70 mm. The standard side wall heights of 150 or 200 mm. Each conveyor pan is supported by a rod that connects to the chain on each side. The other end of the conveyor plates is supported via two rollers on the track. The rollers follow the track and the pan pivots about the rod, creating the tipping action. The pans are pulled in the lower run via the flight axle and pushed in the upper run.
The lowering of the rails in the discharge station and the pivoting arrangement of the pans enable the process of discharging and the flipping of the pans in the area of the drive and tension stations.
The discharge stations may be located in such a way that an optimum feeding of silos or hoppers is ensured. They are activated and monitored by a programmable logic control. When the discharge stations are activated, the inlet point opens the access to the rail recess of the discharge station by means of a geared motor. This inlet point may be remote controlled. Additional monitoring by means of a limit switch ensures that there will be no roller in the area of the inlet point during the switching operation.
The AUMUND pivoting pan conveyor, as part of a long history of conveying technology, excelled above all by its multitude of possible applications.
In the last years orders for modernization of old clinker halls by means of pivoting pan conveyors had a considerable share in the order intake. Often, old clinker halls are equipped with bridge cranes. In permanent operation, these cranes distribute the continuously conveyed clinker in the hall or transfer it to the mill hoppers. At the same time, additives, such as gypsum and slag must be transported to the corresponding mill hoppers. For modernization of clinker halls, AUMUND has realized several installations using a pivoting pan conveyor to provide the mill hoppers automatically with both clinker and additives. Level detectors at the mill hoppers indicate the clinker requirement and control the pivoting pan conveyor with its discharge stations.
The pivoting pan conveyor is functional, efficient and achieves a constant and uniform material distribution with little effort, demonstrated by its very low power demand. In addition to its considerably lower dust generation contributes to environmental protection and humanization of industry.
