46 行 Each respective design is progressively more energy efficient, but all are based on a countercurrent flow of hot air rising from the burners in the calcining zone through the downward material flow. Our standard linings for vertical shaft kilns consist of wear-resistant hot-face linings and thermally efficient backup linings.
ContactDue to the vertical arrangement of the shaft kiln, and the compact layout of each functional area, the floor area is reduced Low investment. The steel structure of the vertical kiln has fewer machined parts so its processing cost is low and the installation difficulty is not high.
ContactShaft kiln, also known as vertical kiln, vertical shaft kiln, is a vertical and fixed clinker firing equipment.The raw meal ball with coal is fed into cement kiln from the kiln crown, and raw meal ball moves from top to bottom, air move from bottom to top. In fact, the physical and chemical changes of shaft kiln are similar to that of cement rotary kiln.
ContactMany 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
ContactThe next common type of kiln is the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel

Contact12 VSBK has a vertical shaft of rectangular or square cross-section. The shaft is located inside a rectangular brick structure; the gap between the shaft wall and outer kiln wall is filled with insulating materials clay, fly ash and rice husk. Some of the kilns in Vietnam have also used modern insulating materials like glass wool.
