Roll grinding: allied in quality and efficiency in the ceramic industry

In the ceramics industry, the proper functioning of the kiln is essential to guarantee a quality final product and continuous production. In this scenario, refractory rollers play a fundamental role: transporting the parts with precision and stability throughout the oven.

But what happens when those rollers are dirty?

Durante o processo produtivo, esmalte, granilha e argila se desprendem das peças e acabam aderindo aos rolos do forno.

Over time, this accumulation forms so-called scale — crusts of hardened material that alter the surface of the roll and directly impact the production process.
Among the main problems caused, we can highlight:
– Cracks in parts: caused by knocks or misalignment;
– Encroachment inside the oven: the pieces lose stability, overlap and can break several rolls in sequence;
– Unscheduled stops: require the replacement or maintenance of rolls, impacting the production rate;
– Loss of finish or variation in the thickness of the pieces, compromising the final quality.

How grinding helps avoid these losses

Roll grinding is the equipment responsible for restoring the original surface of the rolls, precisely removing accumulated scale. When carried out with the appropriate frequency and quality, this cleaning protects the integrity of the firing line, avoids unforeseen stops and extends the useful life of the rolls — high-cost items for the ceramic industries.

Differentiators of Servitech roller grinders

Servitech develops robust and reliable equipment, designed especially for the demands of the Brazilian ceramics industry — recognized for its high productivity and technical requirements.

Among the main differences of our equipment are:

• Pneumatic pressure adjustment;
• High cleaning speed, with excellent performance in removing debris;
• Extreme durability, with very low maintenance requirements;
• Rear outlet with blower, for efficient dust extraction;
• Collection drawer, for practical removal of larger waste.

In addition to the standard templates for rolls measuring 3000 mm, 3500 mm or 5000 mm in length, with diameters from 35 to 60 mm, Servitech also develops special projects, depending on the needs of each line.

Good practices that complement grinding

In addition to periodic grinding, some measures in the previous stages of the process also contribute to the conservation of the rolls, such as:

• A efficient deburring, which prevents dirty parts from entering the oven;
• A correct application of engobe, creating a barrier that reduces the impregnation of dirt on the rollers.

Also discover the engobe for protection of RH rollers.

These good practices, combined with the use of grinding, help maintain the stability of the furnace and prevent chain damage.

Roll grinding is an indispensable ally in the search for more productivity, fewer stops and higher quality in the final product. With the right equipment and good practices, it is possible to increase the useful life of the rolls, reduce operating costs and ensure the continuity of production safely and efficiently.
