Rotary Kilns in Expanded Clay Aggregate Production

Expanded clay aggregates, also called exclay, or lightweight expanded clay aggregates (LECA), are a beneficial material in a growing number of Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a lightweight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The heating process causes gases trapped in the clay to expand, forming thousands of small bubbles and giving the material a porous structure. LECA has an approximately round or oblong shape due to circular movement Expanded clay aggregate

What You Need To Know About Aggregates Cement and Concrete

Cement, or Portland cement, is the fine powder that acts as the glue that holds concrete together when mixed with water, sand and aggregates. It is manufactured by heating a precise mixture of finely ground limestone, clay and sand in a rotating kiln to temperatures reaching 2800ºF. This produces cement clinker, an intermediate product, whichExpanded clay aggregate , the free encyclopedia.

Rotary Kiln Uses Mechanical Drive Or Hydraulic Drive As Kiln Drive

Actually, a rotary kiln uses a mechanical drive. Rotary kiln is a slowly rotating device, mainly composed of a motor, a deceleration case, and big and small cones. Big cone normally is split into two parts cause of its large size and fixed into the meddle kiln by bolts. Its speed ratio against a small cone is generally around 5-7.Shrinkage of Calcium Silicate and Concrete Masonry. J.J. Brooks, in Concrete and Masonry Movements, 2015 Geometry of Cross-Section.
