Fault diagnosis for supporting rollers of the rotary kiln

Rotary kiln is a typical large slow-speed running (2-6 rpm) mechanical equipment. As key equipment, rotary kiln is widely used in the cement industry, metallurgical industry and environmental protection industry. It is main-ly composed by transmission system, driving system, sup-porting rollers and heat exchange system [1], as shown in Fig. 1.

Extraction of aluminum from clay - The United States of

Extraction of aluminum from clays by means of acids, such as hydrochloric, sulfuric, or nitric acids, is well known. Generally, the clay is initially ground, and then calcined at temperatures of about 650° to 850° C., followed by leaching with about 6 to 10 normal solutions of acid at ambient pressure and boiling temperature.

Modelling of a rotary kiln for the pyrolysis of aluminium

1. Introduction. The goal of this study is to construct a mathematical model able to predict the physico-chemical processes occurring when particles of aluminium coated with organic materials (polish in the case of cans, cardboard in the case of milk packaging, etc.) are introduced into a rotary kiln in order to be cleared of their organic content.

Rotary Kiln - an overview | ScienceDirect Topics

Graeme Moir, in Advanced Concrete Technology, 2003. 1.3.2 The modern rotary kiln. The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40% by mass and although the wet process enabled the raw mix to be homogenized easily, it carried a very heavy fuel penalty as the water ...
