To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

COAL PILLAR STRENGTH AND PRACTICAL COAL PILLAR DESIGN CONSIDERATIONS By Daniel W. H. Su, Ph.D.,1 and Gregory J. Hasenfus2 ABSTRACT This paper demonstrates that finite-element modeling can be used to predict in situ coal pillar strength, especially under nonideal conditions where interface friction and roof and floor deformation are the primary

The simplest model for coal pillar loading consists of an unstable overburden to surface, known as Tributary Area Theory (TAT), overburden stability then being entirely controlled by the load-bearing ability of the coal pillars formed in the workings ().Whilst for bord and pillar-type mining design purposes, the TAT model to surface has been and can be modified (by the application of either ...

Hardgrove Grindability Index (HGI) is important from grinding considerations and large variation in HGI poses problem of selective grinding of one coal over another and difficulty in achieving desired coal fineness for proper combustion and affects the mill output. e.

Coal mill dust collectors have a substantial effect on productivity, yet have received relatively little attention as companies implement cost-saving programs, like the use of petcoke as a fuel reduction measure. Petcoke is typically ground finer than coal, and it has a particularly sticky nature that makes it more difficult to clean from ...

content required the mill system grinding capacity to increase by nearly 50% when firing P RB coal. Therefore, three (3) Atrita 556S mills were proposed to replace the existing Atrita 550S mills for the P RB coal conversion requirement. The fuel characteristics of P RB coal and original mill system design coal are listed as follows. Fuel PRB coal
