In our manufacturing process, kiln temperatures of 2100°F are carefully maintained and monitored. The extreme heat allows the unique shale raw material to expand and bloat creating a new ceramic product that is stronger than common shale and 30% lighter by volume. Our lightweight aggregate is then cooled and sized to ASTM (C330 and C331) and

From the kiln, the expanded product (clinker) is transferred by conveyor into the clinker cooler where it is cooled by air, forming a porous material. After cooling, the lightweight aggregate is screened for size, crushed if necessary, stockpiled, and shipped. Figure 11.20-1 illustrates the lightweight aggregate manufacturing process.

Get PriceExpanded Shale (and Slate)
Not all shale is suitable for brick, and even fewer deposits are suitable for expanded shale production. The shale must contain minerals (mostly carbonates) that will produce gas at the same temperature as the shale begins to sinter (soften prior to melting). This allows the mass to expand. Rapid cooling preserves expanded voids.

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 yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure. LECA has an approximately round or potato shape due to circular movement in the kiln and is available in

When clay, shale or slate is crushed and then exposed to high heat (3,600 0F) and cooked for a period of time, they expand like popcorn into a very hard rock that is very porous and light weight.
