When the machine works the grinding roller , which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of High pressure suspension grinding mill given an identical condition and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.
Nov 26, 2012 Pressure spring preloading= 8 Ton. Outlet venturi collar height= 370 mm. Classifier deflector blade pitch= 30 mm(classifier closed)/ 150 mm(classifier open) Present operating parameters are as follows:-Current drawing= 31.5 amp (trip setting 35.6 amp) Coal loading= 25 Tons/hour-55% loading (max 36.7 Ton/hr) Primary Air Flow= 48 Ton/hr (max 52.3 Ton/hr)
This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced ... pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw ... Pressure Spring Exhaust Pipe Air Intake Bearing Raw Coal Feed Pipe.
Also, if different materials are to be pulverized in the same mill, it may be desirable to change the compression of the spring assemblies. Because of the large size of present pulverizing mills and grinding rollers, spring assemblies exerting forces within the range of 30,000- 60,000 psi are common.
Mar 03, 2014 Grinding force is applied by pressure spring adjustment. The roller assembly can be moved up and down depending upon the roll condition and coal bed. Separator Body consisting of linear assemblies deflects the air stream to the center of bowl. Mill is equipped with the stationery classification with adjustable vanes for adjustment of coal fineness.
