Our Lamellas in Operation: Wafer and Wafer Plus

Our Seal Plus by Motofrenos seal solution for rotary kilns and other equipment operates with a set of flexible external lamellas that are resistant to temperature and abrasion, generating a reliable and optimal seal operation. The service life of the lamellas is one campaign, between 12 and 15 months of constant operation, the purpose of the lamellas is to maintain their sealing or closing position, to avoid false air intake in the process during the campaign.

As part of our solution, we offer two types of lamellas according to our client’s needs: Wafer Lamella and Wafer Plus Lamella. Our Wafer lamellas are composed of three layers, a spring steel plate, a ceramic paper layer and a thermal steel plate that is in contact with the wear band. Our Wafer Plus lamellas have an additional layer, that means that it has two spring steel plates instead of one, for this reason they have greater mechanical resistance. Its application is mainly in the lower half of the kiln at the inlet, where they have a greater demand in operation due to the loss of material and inclination of the kiln.

The spring steel is a material whose mechanical properties allow the plate to accommodate the radial deformation of the kiln; its hardness and mechanical resistance properties allows them to have the same guarantee of duration during a campaign for normal kiln operations.

The ceramic paper is manufactured with material whose thermal insulation properties allow the plate to dissipate the temperature coming from the kiln and the thermal steel and therefore protect the spring steel.

The thermal steel or contact steel is a material that has a low coefficient of friction, this allows it to be in contact with the moving element without the plate wearing out prematurely. In addition, it has a special chemical composition that allows it to withstand the high temperatures of a kiln and other rotary equipment.

Our seal solutions are custom designed, they fit the size of the kiln or rotary equipment. According to the current needs of the client, we supply all the parts that compose the seal at a competitive price and in a short time delivery compared to other alternatives on the market. Additionally, we work together with our clients throughout the process with highly trained personnel, which facilitates, optimizes, and makes the seal installation very reliable under worldwide standards.

From the first time, we do things right!
