Roller Hearth Kilns

ROLLER KILNS – FOR TECHNICAL CERAMIC / GRINDING MEDIA / TILES etc.

The roller hearth kiln, initially developed for table ware, is used now for more elaborate and  diverse products. Compared to tunnel kiln, roller hearth kilns do not need the thermal indifferent kiln cars or the    heavy lining and the large rail network. The resulting advantage is a considerably shorter firing cycle.

Therefore by firing in single layers lower energy consumption can be achieved and less space is  required.

Roller hearth kilns are built in modular construction with light brick lining. In addition to further energy  savings, roller hearth kilns offer advantages for assembly.

For firing grinding balls, H.E.R.O KILNS provide both tunnel kiln and roller hearth kiln. Due to specific advantages compared with tunnel kilns, the market share of roller hearth kilns has increased. Particularly with regard to technical ceramics such as grinding balls, substrates and hard ferrites. Generally the highest grade of automation can be achieved by using roller hearth kilns. The transportation by rollers enables a fully automation-line production by including loading and unloading and connectible buffer systems for unloaded or loaded transport devices. At present, H.E.R.O KILNS roller hearth kilns can withstand use for continuous firing up to a temperature of 1650°

The single-layer kiln is divided into pre-fabricated  modules that make transport and assembly easier. No foundation works need to be carried out. All that is necessary    is a flat floor on which to position the kiln. The special frame design improves access to the roller holder bricks zone so that roller flocking tasks can be carried out. Where there are systems that   recover cooling air to be used   as combustion air (MDR, SPR), a protective cover is incorporated on all burners.
