Our external lamella seals are custom designed to fit the size and conditions of each project, keeping the equipment 100% original. The main objective of any seal is to prevent false air intake in the operation of rotary equipment such as: kilns, horizontal ball mills, dryers and coolers.
With our team of experts, we design and supply all the parts that make up our sealing solution at a highly competitive price and delivery time compared to other alternatives in the market. We consider ourselves partners with our clients, which is why we work close together with them to provide a comprehensive solution that meets their specific needs.
Additionally, we provide personalized support through our qualified personnel to facilitate, optimize and carry out a reliable installation of our products.
It is very important for us to support our clients and guarantee the optimal operation of the seal. As part of this purpose, we also design and supply HK kiln spare parts at the inlet and outlet. When these parts are not manufactured and installed properly, the seal can deteriorate prematurely. Our spare parts are manufactured from special steels and high-tech raw materials, each according to its purpose in the operation of our seal solution.
Wear band
The wear band is manufactured with a special anti-wear material to guarantee its service life due to the constant friction with the lamellas. The anti-wear material is a special alloy of fine-grained steels with a typical hardness between 400 and 450 HB. Its high strength, toughness and tensile load make it a very resistant material to plastic deformation and abrasive wear due to sliding and impact.
Lifter system at the inlet
This improvement consists of extending the length and diameter of the current lifter in order to recover and guide the greatest possible amount of material back to the process. This element has the property of a water mill in order to collect all the material that does not reach the process.
The raw material “raw meal” reaches the kiln’s cone at up to 900 degrees Celsius, not having a good size lifter and an appropriate refractory steel characteristic, can deteriorate the seal prematurely in cases where there is material overflow.
Nose ring at the outlet
This complete series of casting parts form a perfect ring around the outlet or kiln’s nose in order to protect against deformation, clinker abrasion, chemical attack and high temperatures which reach between (1450-1550 °C) to this area of the kiln shell.
The nose ring is cooled by a flow of ambient air, which acts as a thermal insulator to prevent excessive heating of the ring. It has two sides, a cold side that is bolted to the shell right at the outlet and a hot side, which is covered by a protective layer of thermally insulating concrete.
Tail casting at the inlet
These casting blocks segments form a complete ring around this area and are made of heat-resistant steel with a high chromium content, they have a flat T-shaped structure and are bolted to the kiln’s inlet.
The tail casting has two sides as well, a cold side that is bolted to the rotary equipment and a hot side which is covered by a protective layer of thermally insulating concrete, with the objective of protecting the kiln’s inlet area from gases flow and hot fine material, these two can range between 800-1100 °C, in addition to protecting this area from the abrasion of the material fed into the rotary equipment and the negative influence that alkalis (Na-K-Cl) and sulfur have on steel.
Sugar scoop
It consists of tongue-type plates segments, made of heat-resistant steel and assembled together, forming a half-circle of the kiln at an angle of about 170°. They are assembled to a seat or fixed plate right at the kiln’s inlet.
The sugar scoop has two sides, a cold side that is bolted or assembled to the back wall and a hot side, which is covered by a large protective layer of thermally insulating concrete. This part has the purpose, depending on its configuration, of transporting the material into the kiln from the tower.
We are aware of the demanding operating conditions of these parts due to high temperatures and exposure to abrasion when coming into contact with raw materials and clinker. To meet these harsh conditions, our materials are thoroughly evaluated under high quality standards, dimensional inspection, hardness testing, microstructural, chemical and mechanical analysis and non-destructive testing.
