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.
Apr 01, 2014 These have impacted the coal mill and power plant operation safety and reliability. The Vertical Spindle mill model was developed through the authors work before 2007. From then, the new research progress has been made in modelling and condition monitoring for Tube-ball mills and is reported in the paper.

Jan 29, 2010 Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
Dec 13, 2011 A vertical spindle mill is also designed for pressurized and suction type requirements. Boiler designers use this type of mill for poor quality coal as this type of mill rejects foreign materials like stones and other high density materials. The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills.
