The running back was on the field for 61 percent of the offensive plays, with Tyler Allgier at 35 percent and Cordarrelle Patterson at 13 percent. Plus, Smith noted, Robinson's presence in and of itself can be a factor for the offense. "Sometimes, his impact away from the ball can open things up," Smith said in his press conference.

How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.

A trommel is a rotary cylindrical structure that is rigidly attached to the discharge end of a mill. The intended operation of the trommel is shown schematically in Fig. 1. It contains moulded screen panels or wire mesh and can have different aperture configurations in each axial section depending on the intended duty.

Dry and wet ball mills have the same basic components, but there are some structural differences: 3 Discharging part Discharging port: Dry ball mill: The ball mill needs to be equipped with an air induction device, a dust exhaust pipe and a dust collector. The structure is more complicated, and the discharge port is straight.

Frequently, check the ball mill discharge trommel screen and dispose of any foreign objects on the screen. The ball mill is susceptible to variations in ore hardness resulting in various grinds at constant throughput, or alternatively, various tonnages at constant grind. The variation in grind is not directly determined.
