Energy saving rotary kiln: kiln mainly includes: the kiln shell, it is the main body of rotary kiln ( rotary ), the kiln shell plate thickness around the 40mm plate, rim around, due to load is relatively large, the kiln shell plate to be thicker. Thrust roller is blocked by the role, roller itself has no power. The bearing has a cooling water circulating cooling. Kiln eat eat by roller deflection roller kiln, and the central lines have a certain angle, make riding wheel to kiln with upward force, so that the kiln shell. Sometimes sprinkle some raw meal powder or roller clean, increases the friction coefficient, also can make the kiln body. In the hydraulic system of endless action, the internal pressure.
The kiln body to eat, as long as the tyre and support rollers between the two and toner, reducing the friction force between the both. The company has independent import and export rights, in order to produce large, medium-sized mining machinery, metallurgy, building materials equipment, set the development, production, sales as one of the joint-stock enterprises, the company headquarters is located in Zhengzhou West Road Machinery Industrial Park, since the establishment of the company, the enterprise with modern management methods Seiko production, independent innovation, brings together a number of talents in science and technology. We can through the kiln shell and tyre with their estimated relative movement between the kiln shell oval deformation degree. In order to reduce the kiln shell on the rim thermal radiation, causing the roller temperature through the high, between the two are provided with insulation to reduce heat radiation. In the kiln tail about a metre long place is conical, made from the preheating of inlet chamber to feed can be more smoothly into the kiln.

If the gap is too large, the kiln shell and tyre relative movement, friction more interest, also can make the kiln shell oval deformation is more and more serious. Until the kiln body touches the Y1 position and eat. Kiln shell lined with a layer of about 200mm of refractory brick. The kiln shell and tyre exists between the heat conduction rate difference, must use an external windmill to help the kiln shell heat balance, reduce the temperature difference between the two. Company under the assembly, processing, machine processing, punching shaft six workshops and four branch companies and a research institute, and the holdings of Zheng mine forging Limited company. Company existing staff 880 people, senior engineer 138 people, medium level skilled workers more than 200 people, the company is to cooperate with foreign research institutions, the introduction of domestic and foreign advanced test equipment and production line inspection technology, and Denmark, Germany Smith Burleigh Hughes company and a number of University and other scientific research units to form a long-term strategic cooperative partnership. Production covers an area of 66000 square meters. Since the support roller kiln tyre width than some, in order to make the tyre and support rollers can move up and down, wear average. Eat, if Y1 switch fault, kiln experience reach Y second switch, the system will alert ( the kiln body is beyond the scope of the 30mm eat ), if it is related to the third switch, the system will jump out of the vehicle ( this time to eat the scope beyond 50mm ). Rotary kiln ( rotary ) to eat, if the first switch is faulty, then kiln ( rotary ) involved in the second to switch, the system will alert, but not to jump out of the vehicle, with thrust roller kiln shell have lower limit limit. Rim, bearing, support wheel, tyre and support rollers are used to support the weight of the kiln with. The kiln body began to eat, the hydraulic system pressure relief for 2 minutes, stop for 4 minutes, then repeat the action. The tyre is arranged on the end surface of the thrust roller. If the gap is too small, the kiln shell expansion by tyre limitation, kiln brick easily destroyed.
Zheng Henan ore mining machinery limited company is the Chinese Zhengzhou 's largest professional mining machinery manufacturers. The rim is sheathed in the kiln shell, it and the kiln shell and not fixed, tire and the kiln shell also has a piece of iron is separated, so that the rim and the kiln shell retained certain gap between, not too big nor too small. Usually between two lubricating oil.
In the open kiln, the kiln shell temperature rate above the rim, kiln workers required to control rotary kiln ( rotary ) heating rate at 50 degrees C / h, which is favorable for the protection of kiln brick. Thrust roller thrust roller of rotary kiln is restricted ( rotary ) to eat or eat on the limit switch. Repeat the above process can. Otherwise the kiln shell expansion will be tyre limitation. Usually riding wheel than the bandwidth of the 50-100mm mm per wheel, roller bearing is a bearing Babbit, if the loss of lubrication, will make the bearing due to temperature through the high and burn. Kiln shell in running time, because of the high temperature and bearing relationship, the kiln shell with elliptic deformation, which will generate pressure influence on brick kiln, kiln brick life. Rotary kiln ( rotary ), there are generally 2 to 3 groups of supporting wheels. Hydraulic system three to limit switch. When the rotary kiln ( rotary ) have reached Y1 switch, hydraulic system on hydraulic system of action began to eat, eat 1 minutes 4 minutes, 1 minutes, and then repeat eat stop 4 minutes of action, until the kiln tyre touches to the Y5 position.
