China's Leading Manufacturers of Expanded Clay Pebbles for Gardening and Construction******Expanded Clay Pebbles in China A Comprehensive Overview of Manufacturers Expanded clay pebbles, also known as hydroton or clay balls, have gained significant popularity in the horticultural and construction industries due to their lightweight, durable, and eco-friendly characteristics. In China, the demand for these versatile materials has seen a substantial rise, leading to the emergence of numerous manufacturers specializing in their production. This article delves into the landscape of expanded clay pebbles manufacturing in China, highlighting key players, production processes, and applications. The Manufacturing Process The production of expanded clay pebbles begins with the selection of high-quality clay. The clay is then subjected to a high-temperature rotary kiln, where it undergoes a process of expansion. During this phase, the clay granules are heated to temperatures ranging from 1,200 to 1,600 degrees Celsius. This causes the moisture in the clay to evaporate, resulting in the formation of air bubbles within the material. As the temperature rises, the clay expands, forming lightweight, porous pebbles. Once the process is complete, the expanded clay pebbles are cooled and sorted into various sizes for distribution.
