Get the most out of your aging pelletizing and sintering equipment

The efficiency of your process equipment is a critical factor in maximizing your operational profitability. If you are operating aging equipment, you face a difficult choice between investing significant capital in new equipment or modernizing your existing equipment. Our pelletizing and sinter experts will work in close partnership with you to design the most suitable modernization solution for your plant and operations.

Minimize shutdown time

We believe that a holistic approach is necessary to maximize the benefits of any modernization project. This means that each case should be evaluated individually and a site-specific solution developed based on the current process and equipment setup, as well as the objectives of the project. Although some modernization solutions are applicable for most installations, in-depth engineering, project planning, and process expertise are key to ensuring the best outcome and minimizing process downtime.

Available for all pelletizing and sintering equipment

We can upgrade your existing Metso Outotec pelletizing and sintering technology or retrofit other manufacturer pelletizing and sintering equipment, from simple technology upgrades to full turnkey implementation. Our sintering and pelletizing upgrades solutions bring measurable value across the key areas of pelletizing and sintering:

  • Product recovery
  • Plant availability
  • Operational costs
Sinter cooler upgrade options

Leaf seal upgrade

The Elimination of egress and ingress tramp air and containment of nuisance dust improves energy efficiency.  The sealing arrangement adequately maintains air pressure and contains dust.  The seals are installed to the existing upper sidewall seal and lower wind box rotating wall.  They are easily accessible for ease of service and replacement with minimal friction on wear surfaces minimized downtime & maintenance.

Curved rails

The new design includes full support under all rail brackets thus eliminating rail bending.  The cross-sectional area of the rail is also increased to provide stronger bending strength and reduced stress imposed by the rotating pellet car wheel across the rail.  New bolt-on bracket design is easier to assemble, install and align.

Thru rod

Grate Kiln Chain stretch is a major cause of misalignment which ultimately leads to the overheating of Grate Kiln components and added downtime.  Our extended wear-life design provides up to 1-2 years of additional life on a properly maintained Metso Outotec grate kiln chain system.  Experience increased time spans between chain system replacements, shorter routine maintenance stops and improved uptime availability which all translates to an overall increase in production and profits.


Tube spacer

The two-piece tube spacer design can be replaced without the need of removing the chain blanket thru rod which the need of the mobilization of equipment and manpower necessary to split the chain pitch reducing maintenance costs and increasing the uptime of the equipment.


Pallet top

The degmented pallet yop design replaces the one-piece pallet top design which is welded to a support frame with eight (8) individually cast segments. Each of the eight (8) cast segments which are now bolted.  Each cast segment can be manufactured to customized metallurgies to adapt and adjust to individual wear patterns of the annular cooler.  Only the cast segmented top sections need replaced and can be done so at a fraction of the cost and lead-time of the current one-piece assembly.


Plate clip

The grate plate clip bolt assemblies are available in all two, three, and four-finger configurations which incorporates the mounting hardware within the cast grate plate clip.  This eliminates the need for mobilizing huck gun equipment and hoses to the platform area underneath the return strand of the grate kiln chain when performing normal grate plate replacement. The extended wear-life castings and improved single-wrench ease of installation promotes maintenance efficiency and uptime availability.

Grate plate

Grate plates and cover castings are exposed to chemical attack and erosion from the cyclic hot gas heat furnace environment. The new Metso Outotec castings are engineered and manufactured to a stringent proprietary process which extends the wear-life of these castings beyond that of the standard offering.  The new design offers shorter routine maintenance stops and improved uptime.

The Grate Kiln Chain is typically the single highest cost of equipment to maintain within this system. This is due to the extreme hi-heat cyclic temperature swings these castings are subjected to plus the number of high-grade stainless steel moving parts involved.  The new design have a lifespan of up to 4 - 6 years on the chain
skeleton and up to 1.5 - 3 years of life on the grate plates and cover castings.


Non-Metso Outotec components

This portfolio of new grate kiln component offerings is designed to upgrade and improve the overall performance and up-time availability of your non-Metso Outotec equipment.  A combination of casting chemistry and proprietary pattern solidification and flow design requirements yields Grate Plates, Link Cover Castings and Side Plates of superior integrity. This superior Metso Outotec design criteria assures proper temperature and material flow control throughout the pouring process which yields castings that exhibit
exceptional extended wear life characteristics compared to all other brands.
