What is a rotary kiln?

What is a rotary kiln? Your safe and durable rotary kiln solutions, Large rotary kiln manufacturer in China Rotary kiln produced by PENGFEI can be divided into cement rotary kiln, metallurgical rotary kiln, chemical rotary kiln or active lime rotary kiln.   Working principle of rotary kilns: The kiln is a cylindrical vessel, inclined slightly from the horizontal, which is rotated slowly about its longitudinal axis. The process feedstock is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal. Structure of rotary kilns:  Cement rotary kilns are mainly composed of: Kiln shell Support roller device Thrust roller device Kiln inlet sealing Kiln outlet sealing Tyres Kiln hood Kiln driving system Kiln shell: It is a cylinder made by carbon steel plate which the diameter can be 6.9m and length can be 230m. Support roller device Support roller device is mainly composed of support roller, support roller shaft,bearing, bearing liner, bearing bush, etc. It is used to support the rotary kiln and the support roller will directly contact the tyres. Tyres: Tyres sometimes is called the riding rings, normally it is a single circular casting ring or forging ring with a smooth surface. They are installed to the outer surface of kiln shell via some ingenious design as the tyres shall attach to the kiln shell closely meanwhile it allows the thermal movement. Tyres will be supported by a pairs of support rollers which are also machined with smooth surface with the distance in half of the kiln diameter. This structure must allow rotation as nearly friction-less as possible. Thrust roller device: Thrust roller device mainly is divided into hydraulic thrust roller device and mechanical thrust roller device which are used for keeping the safety operation of rotary kilns. Kiln inlet sealing and kiln outlet sealing: Rotary kiln sealings are used at kiln inlet and kiln outlet, while kiln outlet is the high temperature side of rotary kilns with the temperature more than 300℃, however the temperature of kiln inlet is lower, but it is under the high negative pressure, thus sealing condition should be good for both kiln inlet and kiln outlet so that the heat consumption and power consumption can be guaranteed. Kiln hood: Kiln hood is an important part of rotary kiln mainly used for collecting clinker to prevent leakage, meanwhile the hot air from cooler via the exhaust fan will be sent into kiln to adequately use the waste heat and reduce the heat consumption. Kiln driving system: Kiln driving system is composed of girth gear, pinion, motor, reducer, etc. Girth gear is casting parts with two halves, pinion is forging parts, brand of motor and reducer depends on the customers’ requirements.  

What is a cement plant?

What is a cement plant? Complete process for cement plant Cement plant is mainly composed of main production workshop, auxiliary workshop & living and administration buildings. Cement plant is mainly composed of following sections: Mines includes limestone mine, clay or shale, etc. clay raw material mines. Raw meal system includes limestone crushing section, pre-homogenization storage shed, raw meal grinding mill & raw meal silo, etc. Burning system includes kiln inlet section, kiln section and kiln outlet section; coal powder production section if coal is used as fuel Cement production system: clinker silos, cement grinding mill section, etc. Finished product & transporation system includes cement silo, packing workshop, bulk cement loading system, finished cement silo, open storage yard, etc. Dry process cement production process includes 8 sections: Raw material quarry Raw material proportioning, blending and grinding Re-heater phase Kiln system Cooler Cement grinding station Cement packing inished cement storage Raw material quarry Raw material proportioning Preheater system Rotary kiln section Grate cooler system Cement grinding station Cement packing Bagged cement storage

Roller Press System make a good start in our new year’s exportation

With the gradual end of the epidemic, the vitality and potential of the world economy have been further demonstrated and released. Jiangsu Pengfei Group has deeply implemented the new development concept, actively integrated into and served the new development pattern, and focused on building a new journey of first-class enterprises.   At the beginning of the new year,Jiangsu Pengfei Group quickly switched to the "production mode", and the manufacturing workshop was full of spring. It increased its power to improve its production capacity, went all out to catch up with orders and rush to deliver goods, and put itself into the new journey of the new year with the spirit of "rabbit".    The first 180-160mm roller press for New Year's foreign trade export was sent from Shanghai Port to the site of Bangladesh MIR project, which is another important project for Jiangsu Pengfei Group to participate in the construction of "the Belt and Road" and build a new development pattern of "domestic and international double circulation"; After the roller press system is installed and put into operation, the output of grinding platform will be increased from 75 tons to more than 200 tons. The cost reduction and efficiency increase will be achieved through advanced equipment and technology, and the cement enterprises in Bangladesh and other South Asian countries will be assisted to achieve energy saving, carbon reduction and green development.     Jiangsu Pengfei Group is the world's leading solution provider of rotary kiln and energy-saving grinding system, a listed company on the main board of the Hong Kong Stock Exchange, and a national champion demonstration enterprise in the manufacturing industry. It has the ability to provide project consulting, engineering design, technology research and development, equipment manufacturing, complete sets of equipment, general integration of installation and commissioning, and general contracting services. Its products and services are widely used in building materials, metallurgy, mining, environmental protection and other industries, It has exported products and provided "one-stop" solutions to more than 70 countries in the world, including 50 countries along the "the Belt and Road". Jiangsu Pengfei Group's nickel mining enterprises and cement enterprises in Indonesia, Vietnam, Myanmar and other Southeast Asian countries have become famous, established a good brand image and become an important supplier of local nickel rotary kiln, roller press and mill.

Jiangsu Pengfei Group EPC project- Anhui wanwei annual output 2 million tons grinding station technical transformation

PFG180-140 roller press and ϕ4.2*13m cement mill are used in Anhui Wanwei Group Co., Ltd. The total investment of the project is about 47 million yuan. After the completion of the project, it is estimated that the output per hour of two mills in the grinding station will double, and the unit power consumption of cement products will decrease by more than 20%, which will greatly reduce the production cost and improve the competitiveness of wanwei cement market. Anhui wanwei high tech materials Co., Ltd. is the core enterprise of Wanwei Group Co., Ltd. (hereinafter referred to as wanwei group). The company has 6000 T / d clinker production lines, two 1000 t / d clinker production lines, four cement mills, an annual output of more than 3 million tons of cement and clinker, and an annual digestion of nearly one million tons of industrial waste residue. The main products are ordinary silicate 42.5 grade, 52.5 grade, composite silicate 32.5 grade cement and other varieties. Among them, composite cement is favored by the market because of its high workability, high strength, high durability and other characteristics. Under the premise of safe construction, Jiangsu Pengfei group strengthens process control, strictly follows the principle of "advanced, mature and high standard" from the whole process of project process design and complete set supply, strictly pays attention to construction quality and construction progress, ensures the expected transformation effect, builds the project into a high-quality project, strives to be completed and put into operation as soon as possible, and presents a gift to the 100th anniversary of the founding of the party.
