Economic hoffman kiln with various advanced brick making machinery

Hoffman kiln


1.What´s the hoffman kiln and what´s its use?

The Hoffmann kiln is a series of batch process kilns. Hoffmann kilns are the most common kiln used in production of bricks and some other ceramic products.It´s used for for baking dried bricks.

2.The fuel for firing can be coal,gas,oil etc.And the yield of perfect bricks will be >90%

3.The structure and working principle of hoffman kiln

a Hoffmann kiln consists of a main fire passage surrounded on each side by several small rooms. Each room contains a pallet of bricks. In the main fire passage there is a fire wagon, that holds a fire that burns continuously. Each room is fired for a specific time, until the bricks are vitrified properly, and thereafter the fire wagon is rolled to the next room to be fired.

a "Hoffmann kiln", "ring oven" or "ring kiln" was a massive oven in which clay was baked at a temperature of around 1,000° Celsius (1830°f) to produce bricks and tiles. It was a circular, elliptical or rectangular brickwork structure that consisted of an endless tunnel, divided into 12 to 24 chambers, all interconnected to each other and to a main flue.

The Hoffmann kiln is a so-called "continuous kiln" - it burns 24 hours a day, 7 days a week, 365 days a year (except when it goes down for maintenance). Before its invention, bricks and tiles were fired in so-called "periodic kilns"
