7.What Problems Will Be Encountered In The Production Of

When the barite mill is fed with too much or too little material, it will cause insufficient grinding of the barite mill, resulting in that the finished powder cannot be discharged in the circulation air channel under the action of the blower in time, thereby increasing the work load of the blower , Resulting in accumulation of powdery materials in the air duct, which eventually causes the air Feed mills must be therefore calibrated regularly. The mill should be re-calibrated if density or moisture change more than 3%. Meter-type feed mills can be calibrated by 2 different methods. The Timed Method or the Simultaneous Method. The Timed Method is the easiest. The number of hammers used for a hammer mill of 1,800 rpm, should be 1 for every 2.5 to 3.5 horsepower, and for 3,600 rpm, one for every 1 to 2 horsepower. Hammers should be balanced and arranged on the rods so that they do not trail one another. the associated maintenance and operational problems. Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment.
