A barrel reclaimer has a drum member with axially extending series of openings provided with buckets for taking material from a stockpile. Bridge-type bucket wheel reclaimers and drum reclaimers. High-performance and robust systems are needed for the high performance handling and blending of. Barrel Reclaimer for Base mix. TRF’s Barrel Reclaimers are operation at major steel plants in India. The reclaim capacity of TRF Barrel Reclaimer is. TPH.

It also appears that the arrangement of each series of bucket openings as an unbroken row assists this effect further. Up to buckets can be arranged in 6 to 8 parallel rows with these symmetrical buckets swiveling automatically in the pre-selected working direction. In applications where reclaiming in two different directions is required, machines are equipped with two rakes, one on each side, which are activated automatically according to the rotational direction of the drum.
We design, fabricate and supply a wide-range of reclaimer machines ranging from bridge bucket-wheel reclaimers to boom type bucket-wheel reclaimers and drum or barrel machines. A barrel reclaimer comprising a drum member according to claim 1.
Next Patent Apparatus and method Thus, the five central circumferential rows have six openings at equal angular intervals and the number of openings in each row then decreases towards the drum ends, there being only one opening at each end circumferential position.
Metallurgical slag filtering apparatus which effects uniform charging of a conveyer belt. The remote end 30a of each auxiliary opening is generally circular and the width of the opening immediately preceding the rounded end is less than half of the width of the bucket opening.
BARREL TYPE BLENDER RECLAIMER & TRASNFER CAR
In regions with extremely low temperatures, rakes can even be equipped with hardened tines that are able to break frozen surfaces. Bulk material handling and reclaiming equipment. A trolley speed controller, developed in-house by TAKRAF, is then employed as this increases interaction efficiency between the two bucket-wheel trolleys.
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. With this design, the need for the transfer car and its pit are eliminated. We’re also able to provide bridge bucket-wheel reclaimers for one or two directional reclaiming and all our machines are automated. 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.
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. A drum member according to claim 1, wherein the or each auxiliary opening has a rounded end remote from its associated series of openings.
In bagrel manner, power transmission between bucket-wheel trolley and bridge is enhanced which has a positive effect on machine life. It is also found to relaimer an advantage if each axial series of openings has its individual openings substantially uniformly axially spaced from each other. It is a feature of the illustrated construction that the non-uniform axial distribution of the buckets is obtained while arranging the buckets at each angular position in an unbroken, uniformly spaced, axial series.
In these, the barrel drive is recliamer and buckets are oriented to suit either direction of rotation.
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 provision of auxiliary openings of the forms discussed rwclaimer found to increase the rfclaimer resistance of the drum member. Integral hydraulic jacks are provided to raise the machine for slewing the bogies. An embodiment of the invention reflaimer be described by way of example with reference to the accompanying drawings.
A drum member for a barrel geclaimer, said drum member comprising a cylindrical wall and a plurality of series of openings in said wall, each said series of openings being arranged in a row extending longitudinally of the drum, bucket means projecting outwardly of said wall at each said opening for gathering bulk materials, at least one of said series of openings being disposed at a spacing from at least one end of barerl drum, an auxiliary opening being recalimer in line with said at least one series of openings between the end of said series of openings and said at least one end of the drum, the or each said auxiliary opening having opposed sides defining a width of the opening which tapers inwardly with increasing distance from its associated series of openings.
Despite the precautions that have been taken in the design of such equipment the problem remains that barrel reclaimer drums are prone to fatigue cracking after a relatively short operating life, in particular because of the higher local stresses occurring at the bucket openings.
A SumoBrain Solutions Company. Metso in your language. In this project the reclaimer is working on two parallel stockpiles and it can be moved between with a transfer car. To go to the correct working position the reclaimer uses a GPS system.
T Barrel Reclaimers Made-to-Order for Bhushan Power & Steel – [email protected]
Alternatively, the machine may be equipped with slewing bogies to permit transverse travel on rails laid at ground level. Bridge type Bucket Wheel Reclaimer in Russia. In the case of parallel pile arrangements, a transfer car is provided, running in a pit across the open end of the stockpiles, to enable the reclaimer to be positioned on any pile. Find out more I baarrel.
Our typical machines cover the following flow rates and sizes:. A drawback with this design however is the increased number of pivot joints. 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 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.
