Material Handling

Feeders
FLSmidth Minerals offers inclined apron feeders for extracting from a dump hopper and feeding to a crusher.
The apron feeder is of heavy duty design with two roller chains, travelling wheels and links, and heavy duty apron plates bolted to the chain links and overlapping each other.
The machinery frame is a sturdy welded and bolted main frame construction with flat steel rails for the travelling wheels of the roller chains and carrying the components of the apron feeder.
The feeders are driven by a dual drive arrangement with a heavy main shaft, directly coupled to the motors at both sides of the main shaft. The main shaft is supported in double row self-aligning roller bearings mounted in heavy steel housings bolted to the machinery frame. The chain wheels are parted in halves and are turnable to reverse direction.

Stackers-Reclaimers Products

Bucket Chain Excavator
The Bucket Chain Excavator, type BCE, is designed particularly for sticky bulk materials.
The store consists of two or more longitudinal stock piles stacked according to the Windrow method. While one pile is being stacked, the other is reclaimed at right angles to the direction of stacking.
The store normally has two stacking bridges, one at either end. The material enters the store on a rubber belt conveyor running along one side. It is discharged onto the upper conveyor on the stacking bridge in operation and proceeds to the lower reversible shuttle conveyor which stacks the material longitudinally according to the Windrow method.

Circular Bridge Scraper
The circular bridge scraper, type CHO, is designed for continuous chevron stacking in one ring shaped pile.
Stacking is effected by a fan shaped sprinkling action in an arc determined by the type of material being processed to ensure appropriate homogenization.
Reclaiming at the other end of the pile is effected by a bridge reclaimer working parallel to a radius line.

Longitudinal Bridge Scraper
The longitudinal bridge scraper, type LHO, operates with two piles. One pile is stacked while the other is being reclaimed. The material entering the store on a rubber belt conveyor is discharged from the jib of the stacker traveling on rails alongside the store at a preset speed.
Reclaiming takes place from the end of a pile at the natural angle of material slide. The bridge runs on rails on either side of the stockpile. On the bridge is mounted a raking harrow system whose sweeping movements cause the material to slide to the pile base.
To loosen sticky and non-free flowing materials active live harrows are available.

Mobile Stacking Conveyor
Mobile stacking conveyors (MSC) provide our clients with an efficient, flexible means of conveying material. The MSC has the lowest average cost per ton of any stacking method and enable stacking in advance and retreat configurations as well as the ability to stack radially and laterally.
Our conveyor designs provide clients with automatic leveling and guidance systems, GPS navigation systems, rugged construction, up to 98% availability, and operating costs as low as $0.05/ton.

Portal Scraper
The non-homogenizing portal scraper, type PS, is normally used in a production line as a bulk material buffer store. The store operates with stockpiles placed in line. While building up one pile by cone shell stacking, another pile is being reclaimed.
The material enters the store on a rubber belt conveyor running along one side of the store. It is discharged onto a stacker jib which is raised and lowered in order to reduce dust emission. Alternatively, stacking can take place by using a tripper car supported by a frame structure above the pile.
The stacker and the portal scraper travel on separate rails along the store.
The portal scraper consists of a portal frame with a scraper chain system. The material is reclaimed by the scraper chain system and transported in a constant flow onto an outgoing rubber belt conveyor.
The PS1 (portal scraper with one arm) and the SPS1 (semi portal scraper with one arm) is provided with one scraper chain only. The PS2 (portal scraper with two arms) has a primary and secondary scraper chain working on either side of the pile while the portal moves to and fro.
The two scraper chain systems are linked together at a knee joint. The secondary scraper chain lifts the material to the crest of the pile feeding the primary scraper chain system. The primary scraper chain system conveys the material to the outgoing belt conveyor.

Radial Stackers
FLSmidth Minerals designs heavy duty radial stackers for handling a wide variety of materials ranging from flash to coarse aggregate material.
Radial stackers are located throughout the world with multiple systems operating in the United States, Chile, China, and Papua New Guinea.

Side Scraper/strong>
The longitudinal side scraper store, type SS, is used in a production line as a relatively small bulk material buffer store.
The store operates with stockpiles placed in line. While building up one pile by cone shell stacking another pile is reclaimed. The material enters the store on a rubber belt conveyor along one side of the store. It is discharged onto a stacker jib which is kept close to the pile crest to reduce dust emission.
Alternatively, stacking can take place by a tripper car supported by a frame structure above the pile. The stacker and the side scraper travel on separate rails along the store. The side scraper reclaims the material by means of a scraper chain system which removes one slice at a time from the pile.
