Vertical Shaft Brick kiln

Vertical Shaft Brick Kiln (VSBK)


Working Principle And Brief Description.

Operation is round-the-clock and annual production of up to 60 lakh bricks has been achieved from commercial VSBK’s operating in India and across. The kiln can be operated throughout the year and even during monsoon time.

Vertical Shaft Brick Kiln (VSBK) gives you unmatched flexibility of operation, good product quality, and substantial saving in energy costs. You can plan a precise production schedule and produce the exact quantity of bricks that you require. Once operational, loading and unloading are carried out simultaneously. In general, one batch of bricks is loaded (and one unloaded) every one and a half to two hours. The bricks remain inside the kiln for approximately 24 to 30 hours instead of the 20 to 30 days required with a BTK. This reduces the working capital substantially.

The choice of fuel is based on cost considerations and the quality of the product desired. Based on the location, coal, and even lignite pellets are being used effectively. However proper firing control and optimum quality are achieved with low volatile coal having a calorific value between 4000 – 5000 KCal/kg to raise the kiln temperature to around 1100 degree centigrade. High calorific value coal is not recommended for VSBK operation. Recommended coal size is between 5 to 50 mm. In recent times where suitable coal is not available, VSBK has been operated with waste biomass-based green solid briquettes. It has the equivalent consumption to coal and produces identical quality.
