Wear Protection in Cement Production

Wear Protection for Cement, the Mega-Material

The broad spectrum of Kalenborn Abresist wear products used in cement production applications offers the appropriate solutions, which our wear protection specialists implement locally the world over. Cement is the most commonly produced material in the world. The huge quantities of material required cause wear in nearly every part of the production process: from the extraction of the raw material from the limestone quarry to the grinding and conveying of all feedstocks, to the processing of the clinker after the rotary kiln. In cement production, our wear resistance solutions and products reduce wear in all these applications and in other areas as well.

Cement Production – Raw Material Extraction and Processing

Even in the quarry, wear protection linings for buckets, trucks, and conveyor systems are a valuable investment in equipment availability. For subsequent processing in the cement works, Kalenborn Abresist provides wear-resistant and anti-friction linings to ensure the long service life and cost-effective operation of plant components. One good example of this is the combined wear protection solution for the sifter housing with KALOCER® high alumina ceramic in conjunction with hard overlay welded plates made of KALMETALL® above and below.

Cement Production – Clinker Production

From homogenization to the raw mill and from preheating to charging the oven – Kalenborn Abresist provides technically and economically optimized wear protection for every area. After the rotary kiln, our thermostable materials KALCRET®KALCOR® or KALMETALL extend service life in the clinker cooler and in the downstream equipment and lines. Just about every component involved, such as crushers, chain conveyors, and bucket elevators, can be effectively protected against wear and the resulting downtime and production losses.

Cement Mills

The transportation of clinker from silos or bunkers to the cement mill and the subsequent crushing process also subject components and machinery to abrasion. And although adding blast furnace slag or fly ash reduces the cost of the cement, it also increases wear. In addition to supplying linings for feeders, mill housings and separators, the range of wear protection services offered by Kalenborn Abresit also includes the regeneration of grinding tables and rolls by way of hardfacing and the supply of abrasion-resistant mill rollers and nozzle rings made of KALCAST. A further step in the reduction of wear in cement production.

Cement Loading and Transport

Kalenborn Abresist wear protection materials provide economical protection for components involved in handling the finished cement. In equipment used to transport the cement to silos, for example, ABRESIST fused cast basalt is used. Close attention is also paid to wear protection and anti-friction properties in the equipment used to load the cement onto trucks, freight cars and ships, in order to guarantee thousands of hours of trouble-free operation during cement production.
