Reclaimers

Power and Performance for the Mining Industry

Designed to transfer the coal stock pile to the Coal Handling Pre-Plant (CHPP) or to the Coal Loading Facility, these machines are critical to any CHPP. Demands for product availability and higher feed rates require the power transmission components to exceed the industry standards now and into the future.

Operating conditions like this require the best in design and innovation, and Tsubaki is the proven name in the field for delivery on performance and increased profitability.

For these machines Tsubaki has designed a made-to-order Stacker Reclaimer Chain.

With a wide variety of options, these chains are specifically designed and manufactured to meet the unique challenges of your operation. To help battle against potential dust build up between bushes and rollers, Tsubaki is proud to introduce the improved anti-dust capabilities for the Bearing Roller Conveyor Chain. Also widely utilized are Tsubaki's highly customizable Large Scale Conveyor Chains. With a wide variety of base materials, corrosive resistant coatings, attachments and rollers available, Tsubaki is confident we have a Large Size Conveyor Chain that can meet the unique challenges of your mining site.

Stacker Reclaimer Chains

reclaimer chain

Stacker Reclaimers are popular when heavy industrial processes require large storage piles of raw material. Reclaimer chain and flight assemblies function like scraper conveyors, less the trough, with flight blades that push material toward a belt feeding conveyor. The reclaimer conveyor's chain with digging flights are supported by rails and structure which span over or across the pile being reclaimed for transfer to plant processes.

Chain for this demanding application should provide the longest service life to achieve the best overall value. Chain must have large bearing areas, high hardness and deep case depth to provide the best performance. Tsubaki engineers have used these principles while retrofitting many reclaiming conveyors with chain and sprockets, achieving longer service life than O.E.M. chains. For superior value and performance, Tsubaki Chain is your best choice.

Note that due to their complex requirements, reclaimer chains are normally manufactured on a made-to-order basis, designed and manufactured to meet the specific unique requirements of each site. Please contact your local Tsubaki representative to obtain certified prints for design and construction.

Improved Anti-Dust Capabilities

3x the wear life of Bearing Roller Conveyor Chain Standard Specs

Tsubaki's Bearing Roller Conveyor Chain Anti-Dust Specification solves the problem of dust causing early wear between bushes and rollers that afflicts standard conveyor chains.

anti-dust specs
  • Exhibits the same performance and efficiency of the Bearing Roller Conveyor Chain, even in dusty environments.
  • Same dimensions as standard R or F rollers and RF Conveyor Chains

Please contact your local Tsubaki representative for further details.

Large Size Conveyor Chains

Along with the above mentioned Stacker Reclaimer Chain, Tsubaki is proud to offer its large line up of highly customizable Large Size Conveyor Chains. As these conveyor chains are highly customizable, with a variety of materials and corrosion resistant coatings, attachments, and roller types available to match the unique conditions of your mining site, we at Tsubaki are confident that our Large Size Conveyor Chains can meet any challenges your site has to offer. Furthermore, because many of our innovative products are a direct result of answering specific challenges presented by our customers, please do not hesitate to contact your local Tsubaki representative if your mining site has unique challenges other chains just can't stand up to.

Detailed information about the chain base material, corrosion resistant coatings as well as types of attachments and rollers available is shown below.

Tsubaki's Wide Selection of Large Size Conveyor Chains

Tsubaki Conveyor Chain is made from carbon steel, high tensile structural steel, or stainless steel ( 300 / 400 Series ) parts to satisfy any application.

General Use Conveyor Chains   DT Series

Our most versatile chain

  Increased Functionality
  Increased Tensile Strength
Wear Resistant/ Heavy Duty Conveyor Chains  
GT Series
Wear resistance between the bush and roller is better than the DT Series
AT Series
Twice the tensile strength of the DT Series, with wear resistance between bush and roller, wear resistant link plates.
               
       
     
   
CT Series
Increased wear resistance between pin and bush. Ideal for conveying cement and other wear inducing materials.
BT Series
Increased wear resistance between pin and bush. Ideal for conveying cement and other wear inducing materials.
Corrosion Resistant Series  
MT Series
Pin and bush are made of 400 Series stainless steel, and the roller of high tensile structural steel. The MT Series has increased wear resistance between bush and roller.
     
               
       
     
        RT Series
Pin, bush, and roller are made of 400 Series stainless steel, increasing corrosion resistance. Link plates are made of carburized steel.
YT Series
Pin, bush, and roller are made of SUS400 stainless steel for increased corrosion resistance. The link plate is made of high tensile structural steel. Higher tensile strength than the RT Series.
               
       
     
        DS Series (formerly NT Series)
High wear resistance thanks to the anti-corrosion/hardening properties of 400 Series stainless steel.
GS Series (formerly PT Series)
Has 1.6x the tensile strength of the NT Series.
   
SS Series (formerly ST Series)
Corrosion, heat, and cold resistance thanks to 300 Series stainless steel.
     
   
NEP Series
Raises the corrosion resistance of general use and wear resistant/heavy duty conveyor chain. (Coated Conveyor Chain)
     

 

Attachment Types

Attachments can be placed at any link spacing.

Standard Attachments (A1, A2, K1, K2, GA2, GA4)

Standard attachments are both economical and versatile.

A Attachments

reclaimer chain

A attachments have a bent link plate on one side. They are referred to as A1, A2, or A3 attachments, depending on the number of bolt holes.

*TSUBAKI may send an A3 attachment for some A1 attachment orders. Contact a Tsubaki representative for more information.

K Attachments

K attachments

K attachments have a bent link plate on both ends. They are referred to as K1 or K2 attachments, depending on the number of bolt holes.

*TSUBAKI may send a K3 attachment for some K1 attachment orders. Contact a Tsubaki representative for more information.

GA Attachments

GA4 attachments

GA attachments have holes in the link plate itself. They are referred to as GA2 or GA4 attachments, depending on the number of bolt holes.

Please note that other non-standard attachments and special "Outboard Roller" (OBR) bearings are available. Furthermore, special sealed, long life outboard rollers to suit highly contaminated areas are also available upon request. Please contact your local Tsubaki representative for more details.

Roller Types

Tsubaki Conveyor Chains use three basic roller types.

  1. R Rollers
    R RollersThe outside diameter of the roller is larger than the height of the link plate.Tsubaki's most basic, versatile roller type. It has a large allowable load and low frictional resistance.
  2. F Rollers
    F RollersF RollersThere is a flange on the roller, attached on the T-pin side, that acts as a guide. Flange rollers are a simple way to prevent side oscillation. They are perfect for rough usage conditions and regular slat conveyance. Be careful when using K attachments, as the attachment area may contact the roller flange.
  3.  S, M, and N Rollers
    S, M, and N RollersThese rollers are effective in alleviating the shock and wear the chain would normally suffer during sprocket engagement.
  4. S Rollers
    The outside diameter of the roller is smaller than the height of the link plate.
  5. M Rollers
    The outer diameter of the M Roller is slightly larger than that of the S Roller.
  6. N Rollers
    The roller diameter of the M and N rollers are the same, but the pin diameter is larger, increasing its strength. (RF26200N and above)
