Vertical Shaft Brick Kiln ... The VSBK is a vertical kiln with a stationary fire and a moving brick arrangement. The figure below shows the VSBK principle in a schematic diagram. The kiln operates like a counter current heat exchanger, with the heat transfer taking place …
The Vertical Shaft Brick Kiln is a civil structure consisting of insulated vertical shafts in which bricks are fired. This is a continuous operation kiln, capable of round-the-year operations. Through VSBK, production can be easily scaled up or down to meet different levels of demand.
Many of these kilns put out 10,000-15,000 bricks per day (this figure may refer to a 2-shaft kiln). Quality is very high and brick wastage is very low when compared to other kilns, being only 2-5% in China. The firing process is completed in about 24-30h as the bricks move from top to bottom. One batch is removed at the bottom at a regular ...
