Feeder deliver outstanding work in toughest site

 

Hongxing feeders are equipped with a heavy duty, model HF vibrator mechanism. With decades of operating history, the HF mechanism is among the most reliable available in the mining industry today. Model HF vibrator housings are fabricated from heavy plate in an open tube style for rigidity and strength. Side plates are precision machined to ensure tight sealing and proper bearing alignment. Activity levels in the European construction sector took a dip in July, depressing an already weak industry. There is usually a seasonal slowdown at this time of year, but coming on the back of a poor first half, the impact has been more noticeable than usual this year. The balance figure is the percentage of positive responses, minus the number of negative ones.
Further reduction of the magnetic field strength creates the ball movement characteristic of Case D. The cluster-like assembly creates a sliding movement that rotates and oscillates up and down the arc of the cylindrical chamber and generates a shearing action between the balls and the inner mill wall.
Bolt-on positive counterweights allow simple field adjustments to increase (or decrease) the length of the stroke. Precision cut gears maintain the proper shaft timing, generating an efficient straight line stroke to convey material down the feeder pan. This type of mechanism allows for the gear timing to be field altered, changing the angle of the stroke. The ability to modify the stroke angle and length allows versatility to optimize performance in a variety of applications.
Step-deck grizzly feeders incorporate two or more sections of grizzly bars, increasing the screening area and allowing material to tumble between decks, significantly improving cone crusher efficiency. Due to the additional height requirement of the step, this arrangement is most common in severe duty models. Case E  shows an arrangement of three magnets configured to produce a closed geometry magnetic field. It causes the ball trajectories to be more uniform and makes the balls fall as projectiles. The falling balls hit the balls rotating in the opposite direction at the bottom; consequently, strong impact collisions occur and a shearing action is created between the colliding balls. The unique feature of this design of ball mill is that the specific ball movement pattern in every case of operation is well defined and highly reproducible. This contrasts with the chaotic and unpredictable ball movement characteristic of other ball milling devices.
The vibrating feeders are wide series, double row spherical roller bearings deliver greater load carrying capacity than standard series bearings, providing long service life even in 24 hour operations. Using the open tube design, the HF units carry large oil volumes to insure proper lubrication of bearings and gears with extended service intervals.
