Cement Industry
Cement IndustryMayerton designs linings for use in cement production. Materials are chosen for rotary kilns and kiln cyclone suspension precalciner. The rotary kiln divides into zones for: long, dry and wet processes (chain section feed cone, preheating, calcining); burning (upper transition, sintering, lower transition); and discharge. Installed “in front” of the cement rotary kiln to reduce the losses and enhance efficiency the suspension pre-heaters and pre-calciners has have three zones including the hot face and safety linings as well as meal chutes. |

Mostly, bricks demonstrating refractoriness, resistance to thermal shock and volume stability line severe furnace operation areas. Bricks include: magnesia-spinel; magnesia-chrome (silicate bonded, direct bonded and rebonded); mid and high alumina (alumina content 50, 60, 70, and 80%); fireclay bricks (super, high, medium and low duties plus semi silica). Castables coat areas exposed to less arduous service conditions, areas hard to reach and areas requiring repair. Chemically bonded refractory castables exhibit strength and density combined with volume stability from ambient to elevated temperatures. Associated features include abrasion resistance. Monolithics include: fireclay; mid alumina (50 & 60%); high alumina (70 & 80%); and phosphate. |
