Raw Materials Analysis & Slip Formulation
Raw materials are categorized in terms of chemical composition, mineralogy, and physical and ceramic properties. These properties are used to create the optimum blend for high quality ceramics.
Ball Clay Beneficiation & Slip Batching
These processes use low and high intensity dispersers, hydrocyclones, sieves, and magnetic traps. Batching is carefully performed according to the weight and volume of the item.
Filter Pressing
Process in which high pressure is used to remove water from the conveyor belt to obtain flat plates with a consistent material density. Work pressure up to 200 PSI.
De-airing & Extrusion Equipment
Flat plates are de-aired in a vacuum pug mill. Final products are extruded with optimum compaction and homogeneity. Pug mill hole diameter up to 13”.
Wet & Dry Turning
Horizontal and vertical hydraulic lathes are available for shaping cylindrical pieces up to 1.2 meters long. Lathes are automatically controlled for the optimal sequencing of operations. Tungsten carbide tools with high wear resistance are used.
Pressing Process
A heated die is pushed while turning the extruded item inside a gypsum mold. Optional threading is available.
Drying & Firing Kiln
Gas fired dryers and kilns are suitable for water removal and ware sintering. Shuttle and tunnel kilns are available for temperatures up to 1300°C. Dryers support temperatures of up to 140°C.
Coating Process
Process in which a surface glass coating is applied on the item.
Assembly & Cement Setting Processes
Processes in which ceramic and metal parts are joined together using cement. Steam is used to speed up the cement hardening process, with temperatures up to 65°C.
