WESMAN BURNERS
In a furnace the re-circulation of products of combustion can substantially contribute to the speed of heating and temperature uniformity. For low temperature ovens and dryers, suitable re-circulating fans are generally provided to achieve temperature uniformity. However, fans are not practical for high temperature furnaces and kilns. Excess air can help in re-circulation but this will result in wastage of fuel. 30% excess air for a 1100 degree centigrade furnace will require additional 24% fuel than stoichiometric firing. In comparison, high velocity gases entrain and re-circulate more than seven times of own volume will eliminate need for fans or excess air.
Feature : Ceramic Tunnel and Kilns • Heat Treatment Furnaces • Car Bottom Furnaces Scrap • Preheaters Galvanizing Tanks

NO BAKE MOLDING PLANT
For preparation of moulds the plant should essentially have a Continuous Mixer and Compaction Table. Sizing of the Mixer has a relationship with the size of the Mould to be prepared and the hourly production rate of the plant. Typically a no bake mould half should not take more than 20 minutes to be filled with sand mix. Based on this as well as number of moulds to be prepared per hour, the hourly capacity of the Mixer in TPH can be determined. Upstream of Rollover Machine is either a Carousel type Rotary Moulding Unit or a Fast Loop type Linear Moulding Line. In both of these, the basic purpose is to provide a time lag to the mould half so that the same gets properly cured before being stripped off the pattern. Carousel is a rotating disc with multiple waiting stations (in the form of small roller conveyors) on it. Fast Loop is a set of powered Roller Conveyors and Transfer Cars to form a closed loop along with the Rollover Machine.
