ESCS lightweight aggregates are fired in a rotary kiln. During this process, an unconnected network of interior voids forms to reduce the material's density and increase its internal friction angle and shear strength. After the fired aggregate has cooled, it's crushed and filtered to ensure a highly regulated particle size.

ural shale is expanded in an oil fired rotary kiln maintained between 1,900 and 1,200 C. At this temperature, the shale is in a semi-plastic state at which entrapped gases are formed and expansion results creating individual non-con-necting air cells. After discharged from the kiln, it is cooled and stored. Table 1 presents the chemical ...

The original U.S. patent on the rotary kiln process for manufacturing "Haydite" expanded shale clay and slate (ESCS) was awarded to Stephen Hayde on February 18, 1918. Hayde had considerable practical knowledge of construction and construction problems, coupled with an inquiring, inventive and resourceful mind.
Based on rotary drum technology, a rotary kiln consists of a large rotating cylinder (the drum) fitted with tires resting on trunnion wheels that help to facilitate rotation via a drive assembly. The horizontal drum is positioned on a slight slope to allow gravity to assist in moving material through the unit.

The lightweight aggregate industry employs the rotary kiln as the primary device for high temperature processing of shale, slate or clay. The product, an expanded shale aggregate, is used in many masonry applications including high-rise buildings, bridge decks, etc. Like all rotary kiln processes, achieving product uniformity is a challenging …
In manufacturing process, natural shale is expanded in an oil fired rotary kiln maintained between 1,900 and 1,200 °C. At this temperature, the shale is in a semi-plastic state at which entrapped gases are formed and expansion results creating individual non-connecting air cells. After discharged from the kiln, it is cooled and stored.

The process produces a consistent and predictable high quality ceramic aggregate that is structurally strong, physically stable, durable, environmentally inert, light in weight and ...
Shale is a sedimentary rock: hardened layers of clay, silt and other minerals — essentially very old mud. When crushed and fired in a rotary kiln at 2,000 degrees Fahrenheit, tiny air spaces in the shale expand like Rice Krispies. The result — expanded or vitrified shale — is a lightweight, gray gravel.
TruGro® is a lightweight aggregate produced from raw shale. Fired in a rotary kiln at over 2,000 degrees Fahrenheit and then rapidly cooled, it transforms into a porous, lightweight, chemically inert and hard material …
Expanded shale, also known to some as haydite, is a lightweight aggregate. It is mined, crushed and fired under high temperatures in a rotary kiln to produce a clean, inert, porous, and lightweight soil amendment.
Rotary-Kiln Produced Aggregate Concrete aggregates come with a wide array of properties that can be used in different applications. Expanded shale, expanded clay, and expanded slate (ESCS) lightweight aggregates are prepared by expending selected materials in a rotary kiln at a temperature over 1000 degrees Celsius (Holm and Ries …
