CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract 1 This paper presents a mathematical model for Tube-ball mills which is developed based on the previous work. The Particle Swarm Optimization (PSO) method is used to identify the unknown parameters of the coal mill model with the on-line measurement data provided by EDF Energy.
CO and O 2 are monitored by a distributed data acquisition and control system. Spontaneous combustion of coal is the most possible ignition source, and CO monitoring is an effective method to detect spontaneous combustion. Experiences show that, auto-ignition may occur in the drying system when CO concentration is above 500 ppm.
It is also possible to connect existing cryo tanks to the mill, using a connection tube with safety valve. CryoMill Typical Sample Materials Due to the automatic embrittlement of the samples during cryogenic grinding the CryoMill is suitable for pulverizing, for example, waste, soil, chemical products, tissue, hair, wood, sewage sludge, bones, plastics, oil seed, paper, plants, pills, textiles ...
Aerated ball tube mills are designed for anthracites, coal, lignite, shale and other materials grinding up to pulverized condition and for continuous operation in coal pulverization systems at thermal power plants and other branches of industry. The coal grinding process in aerated mills is performed simultaneously with coal drying inside the drum.

Tube-ball mill is another dominant type of coal mill apart from Vertical Spindle mill in industry. Compared with the Vertical Spin-dle mills, Tube-ball mills have a much higher grinding capacity. However, there are fewer literatures found in studying Tube-ball mill operation compared with the Vertical Spindle mill. Ma et al.
These mills are scheduled of start up on 2012. Our market share in China exceeds 80% with the largest mills supplied to date being a Ø7.9m x 13.6m 2x8.5MW Ball Mill and a Ø11m x 5.4m 2x8.5MW SAG Mill, being the largest in China.
