Process. 44-45 (1996) 569-581 Component wear in vertical spindle mills grinding coal J. Sligar ' Pacific Power, Sydney, Australia Abstract This paper reports on the contribution of a number of material coal properties and machine operating parameters to the wear of vertical spindle mill components.
rotary cutter held in a spindle. Cutting options are more sophisticated and variable than a drill press by virtue of a moveable table and/or vise (x and y-axes) and vertical spindle movement (z-axis). Many vertical mills also have a rotatable turret for the upper cutting head which provides even greater machining options (b-axis).

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.

Inerting System Design for Medium Speed Vertical Spindle Coal Pulverizers The PRB Coal Users' Group plans to develop a Design Guide for Mill Inerting as an aid to users when designing a mill inerting system. This is a first draft document by the The Group on the subject of mill inerting. Feedback is encouraged. TABLE OF CONTENTS Preface 2
mill (~600 to ~1100 per cent) as well as the dependency of fineness of the streams to the operating variables was demonstrated. The approach taken in this study has proved that development of a classification model for a vertical spindle mill pulverising non-homogeneous materials, eg coal, requires treating these materials as

This paper reports on the contribution of a number of material coal properties and machine operating parameters to the wear of vertical spindle mill components. This assists in the evaluation of mills and coals for particular duties and enables prediction of the likely changes in maintenance regime if these variables are changed.
Vertical Spindle Mills The vertical spindle mill is a medium speed pulverizer and maintains a considerable amount of fuel in the mill system when operating. Coal collects on the grinding table, in the classifier, in the pyrite collection sec- tion below the grinding table, .
