In the trunnion-mounted configuration, the ball rotates in a fixed position (Figure 4.58). The ball cannot move in the lateral direction because it is held in place by a shaft on the top and the bottom of the ball. The valve creates a seal by either fluid pressure forcing a floating seat ring against the ball or pro-stressing the seats and the ...
Ball and tube mills A ball mill is a pulverizer that consists of a horizontal rotating cylinder, up to three diameters in length, containing a charge of tumbling or cascading steel balls, pebbles, or rods. ...

The seal is bolted over the end of the trunnion liner. This is to allow the feed chute to come down through this hole into the mill. The material that forms the seal will be attached around the hole. It may be made from rubber Teflon or maybe just plywood. The other half of the seal is connected to the feed chute.
