Calcining zone is hot zone, will react at high temperatures with lime and brick lining, the lining surface may be eroded softening, decrease time and materials produced will wear lining, refractory damage if poor refractory lined, inside will quickly damage the lining lime kiln, therefore, lining brick firing with the requirements of high temperature, wear, pressure, corrosion resistance and volume stability is better. 2013 company Shandong Province Construction Authority awarded the construction furnace secondary qualifications. Environmental protection under the premise of national initiatives, but also develop design energy saving, environmental protection, high yield new furnace production line, technically realized ventilation and dust, a major breakthrough in air purification desulfurization environmental protection lime kiln, the State Intellectual Property Office issued the invention patents, utility model patent certificate more than 10 items. Double valve with a rotary charging device is gearing hopper and equipped with rotating and lifting mechanism composed of a double gate, a bell material hoist and down through the rope through the pulley block to complete the differential green lime kiln nodulation with a roller coupling with the upper part of the hopper to prevent rotation of the lower portion of the valve when the valve is rotated along with the lower valve fitted cloth spiral cone with two baffles, and rotation angle of 34 degrees at the time of promotion, when even the upward movement of the rod, which slides on top of the flange portion and a helical cut with a cloth cone rotating rod, to limit rotation of the link with the ratchet mechanism, supporting the volume by rotating hopper 0.8-2 cubic meters, power transmission 1.7 kilowatts, 1.3-2.7 speed rev / min Environmental kiln control, the rotation period of 30-60 seconds, the rotation angle is 60 degrees, the disadvantage of this charging device is a cross section of fabric material distribution is not uniform along the kiln, the consumption of steel large, manufacture and operation of the more complex. Resistant refractory concrete is a new work materials. Compared with firebrick, which has simple production process, to facilitate the construction and maintenance of overall good and long life. Lime kiln refractory concrete used, there is portland cement refractory concrete, low calcium aluminate cement refractory concrete, refractory concrete water glass, phosphates and magnesia refractory concrete refractory concrete. Environmental protection lime kiln lock fan, Kim Yong furnace (certified), Hubei lime kiln by Kim Yong Kiln Ltd. Linyi City. Linyi Kim Yong Kiln Ltd. (www.dfyaolu.com) (www.dfyaolu.cc) is an industry leader in Shandong Linyi, environmental protection equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
