The trunnion ball valve is a form of quarter turn valve which uses a hollow perforated and fixed/supported ball to control flow through it A trunnion mounted valve means that the ball is con strained by bearings and is only allowed to rotate the majority of the hydraulic load is supported by the Sy stem constraints resulting in low bearing pressure and no shaft fatigue The line pressure
bearings already coated with a friction reducing surface treatment Use of these coated bearings may result in slightly less clearance than the uncoated CLEVITE 77 high performance parts for the same application This will typically be in the range of 0005 This is because the coating although expected to remain in place during service is considered to be somewhat of a sacrificial

Download PDF 4966471 the present invention provides a sealing assembly to prevent dust infiltration to the trunnion bearing surfaces of a ball mill pulverize assembly BACKGROUND OF THE INVENTION In the operation of any type of plant using pulverized coal for fuel it is common practice to supply raw coal to a ball mill pulverizer to reduce the size of the coal and mix it with air The
In these types of bearing the ball and rolling are retaining in positions by separators This known as cages usually made of brass The inner race should be of drive fit on the shaft so as to rotate with it The outer race fits into the housing and does not rotate A ball and rolling being free to rotate the action in them is not that of rubbing but of rolling between the balls and
The rotating assembly of the mill is supported by two bearings called trunnion bearings indicated in Fig 2 The bearings are static components having bushings on which the mill rotates The components of the mill that rotate on bearings are the trunnions The trunnion is a kind of cylindrical and tubular shaft with thick walls wherein the ore passes through its inner diameter both in the
