Description

Pengfei rotary kiln (Rotary kiln, titanium dioxide kiln, sintering furnace, industrial kiln, kiln, oxidizing pellet) has specifications of 3.2*52m, 3.5*54m, 4.0*60m, 4.3*64m, 4.8*74m, 5.0*78m. Pengfei rotary kiln is the main equipment for calcining cement clinker. It has been widely used in cement, metallurgy, chemical industry, and other industries. The equipment consists of a cylinder body, supporting device, supporting device with gear wheel, transmission device, movable kiln head, sealing device at kiln end and combustion device. The rotary kiln has the characteristics of simple structure, reliable operation and easy control of the production process. Rotary kiln calcination system equipment produced by Pengfei has been innovated through technology. In this system, the most advanced domestic and foreign hydraulic wheel-blocking device, measuring plunger pump with high accuracy, high precision speed regulating valve and contact graphite block sealing device are adopted. In order to improve the degree of automation, the kiln head uses industrial TV to watch the fire, the technological process simulates the fluorescent screen, and the calcination belt uses an infrared scanner to directly reflect the calcination of the belt on the computer. These new technologies have a strong visual sense, convenient operation, and reliable use. The thermal system has been stabilized and the operation rate of the equipment has been improved. Compared with the equipment of the same specification, the operation rate has been increased by 10%, the output has been increased by 5%-10%, and heat consumption has been reduced by 15%.

In addition to calcining cement clinker, the rotary kiln is also used to calcine clay, limestone and slag drying. In refractory production, the rotary kiln is used to calcine raw materials to make its size stable, strength increase and reprocessing. In nonferrous and ferrous metallurgy, iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, and files are sintered and roasted in the rotary kiln. For example, aluminum hydroxide is roasted into alumina in aluminum production; pellets are produced for blast furnace iron-making with aluminum hydroxide in iron-making; iron ore is directly reduced by SL/RN method and Krupp method abroad; tin and lead are extracted by chlorination volatilization roasting method. In the process of mineral processing, the lean iron ore is magnetized by the rotary kiln, so that the original weak magnetism of the ore is changed to strong magnetism, so as to facilitate magnetic separation. In the chemical industry, soda is produced in a rotary kiln, phosphorus fertilizer and barium sulfide are calcined. It has the advantages of low energy consumption, less electricity consumption and utilization of medium and low-grade phosphate rock, and has been widely promoted.

 

In addition, in terms of environmental protection, cement kiln is used to incinerate hazardous wastes and garbage to achieve harmless waste discharge, and waste is used as fuel to save pulverized coal and achieve resource utilization of waste.
