Bridge Bucket Wheel-Reclaimers Reclaimer reckaimer two separately driven bucket wheel and speed regulated trolley. The openings of the several series feclaimer axially aligned in circumferential rows but they are so arranged that the openings are concentrated towards the middle of the drum. A drum member according to claim 1 wherein said opposed sides of the or each auxiliary opening are mutually inclined within a range having one limit at which straight-line projections of the opposed sides are substantially tangential to the adjacent end opening of the associated series of openings, and an opposite limit at which an adjacent end opening of the barrrel series of openings has opposed sides from which straight-line projections extend substantially tangentially to barreo nearer ends of said opposed sides of the auxiliary opening.

All contact information Send a message. When installing two bucket-wheel trolleys, the trolleys can be mechanically linked so that they both share a common trolley drive system.

Rakes are equipped with prongs or scraper rods, depending on particle size of material to be reclaimed, and create a continuous flow of material on the escarpment of the pile over the entire width directly into the reclaiming buckets.

To check the reclaimed material flow a radar system is used. Machines employing two bucket-wheel trolleys are able to achieve a higher reclamation rate, whilst also achieving greater homogenization at lower flow rate fluctuations. The frame F is provided with wheeled bogies B, also in a conventional manner, to drive the reclaimer along a stockpile.

Drum reclaimers are particularly suited to the homogenization and blending of brrel material for sophisticated downstream processes, especially for iron ore or coal processing. You reeclaimer find out more by reading our cookie policy. Our team of experts is there for you Distributor contacts. The drive means for rotating the drum in the frame is not shown because it can be entirely conventional.

Where the plant layout dictates an in-line pile arrange, bi-directional machines can be provided. A number of further configurations are also able to be specified, ranging from the number of mounted bucket-wheel trolleys to the manner in which they are arranged.

Low maintenance due to minimum working parts Durable and dependable Maximum possible homogeneity of material properties and particle size distribution in the resultant blend Better blending. Find out more I agree.

In these, the barrel drive is reversible and buckets are oriented to suit either direction of rotation. The buckets continuously remove thin layers of material from the entire cross-section of the stockpile and discharge this onto a belt conveyor located within the drum.

A drum member according to claim 1 wherein at least the greater part of the openings of said plurality of series of openings are arranged in circumferential rows. Bulk material handling and reclaiming equipment.

Metso global bardel Products Reclaimers Barrel reclaimer. Openings in the drum have scoop buckets projecting from them to pick up material from the stockpile as the drum is rotated and progressed along the rails into the stockpile. Our typical machines cover the following flow rates and sizes: They are provided because it has been found that they have a significant abrrel on the pattern of stress in the drum shell and are able to give a considerable improvement in resistance to fatigue failure.

The material picked up by the buckets is deposited on a conveyor which extends axially through the interior of the drum and which delivers the material to a fixed conveyor at the side of the reclaimer track for further transport.

It also appears that the arrangement reclaimfr each series of bucket openings as an unbroken row assists this effect further. An embodiment of the invention will be described by way of example with reference to the accompanying drawings. We’re able to design and build machines according to our client’s specific flow rate requirements.

TAKRAF boom-type bucket-wheel reclaimers are popular in applications where medium to high flow rates from dumps are being reclaimed. Boom type Bucket Wheel Reclaimer in Brazil.

Material collected in the buckets is discharged in a layered stream onto a belt conveyor contained within the barrel, and is then delivered to a downstream conveyor running alongside the stockpile.

We have now found that the fatigue resistance of a barrel reclaimer drum provided with axial series of openings for reclaijer material into the drum, can be significantly increased by arranging that auxiliary openings of tapered form are provided at the ends of the series of openings.

A number of axial series of openings 8 FIG. According to one aspect of the invention therefore, a drum member for a barrel reclaimer comprises a plurality of series of openings provided with projecting bucket means for gathering bulk materials, each said series of openings being arranged in a row extending axially along the drum, at least one of said series of openings being disposed at a spacing from at least one end of the drum, an auxiliary opening being provided in line with and at the or each end of said series of openings so spaced from a drum end, the or each said auxiliary opening having a width which tapers with increasing distance from its barrek series of openings.

It is also helpful if the individual openings of each axial series are uniformly spaced from each other.

For specific hard-working areas that are in contact with material i. Drum Reclaimers Drum reclaimers are particularly suited to the homogenization and blending of bulk material for sophisticated downstream processes, especially for iron ore reclamier coal processing.

Barrel reclaimer Barrel reclaimers continuously recover material from the full cross section of the stockpile and consequently achieve the maximum possible homogeneity of material properties and particle size distribution in the resultant blend.

The form of the reclaiimer openings 8 shown in the drawings is typical of conventional bucket openings. Because it is supported only at its ends, the drum of a barrel reclaimer is subject to beam loading and as it rotates the structure of the drum is therefore subjected to cyclic fluctuating barrdl. It can operate in fully automated mode or in remote mode.

It is also preferred to provide the or each auxiliary opening with a rounded end remote from its associated series revlaimer openings and to have the width of said auxiliary opening immediately preceding said rounded end not substantially more than half the width of the openings of the associated series of openings. The buckets 10 are double-sided, with a central axial partition 12 extending between end plates 14 and oppositely facing outer scoop walls 16 projecting from the partition 12, so that the drum can operate in either direction of rotation.
