The large bevel gear is fastened to the eccentric turntable by screws and elastic cylindrical pins. The eccentric turntable shaft is supported by two single row tapered roller bearings, so that the radial force of the large bevel gear falls between the two bearings with larger span. Improves the force of the shaft and improves the installation accuracy. The small bevel gear shaft is a single component, which consists of a small bevel gear shaft, three disc bearings, bearing sleeves, bearing shells, floating seals, etc. A total of 22 parts are connected by 10 M12×25 bolts, and the box The body is connected by 8 M16×48 bolts. Only 8 M16×48 bolts can be unscrewed during maintenance and dismantling, and the small bevel gear shaft system (excluding the outer ring of the cylindrical roller bearing) can be removed. It is easy to disassemble and adjust, and the small bevel gear shaft design has three adjustment rings, and the three links are relatively independent to adjust the gap between the bevel gear pair, the bearing and the floating seal. That is, the small bevel gear shaft system has been adjusted as a separate component for the bearing clearance and the floating seal clearance. Finally, when assembling the casing, it is only necessary to adjust the circumferential side clearance of the gear pair. The other bevel gear reducer small bevel gear shaft is a decentralized structure, which is very troublesome to adjust, and it is impossible to take care of the three links at the same time. There are always one or two links in a non-optimal condition, so the structure reduces the installation. Adjusting the time, improving the work efficiency, and more importantly, the components can be in the best working condition, thereby improving the assembly precision of the reducer.
The large bevel gear shaft system is the same as the small bevel gear shaft system. The adjustment links are relatively independent. They are also separate components, including 15 parts including eccentric turntable, large bevel gear, two-disc bearing and bearing sleeve. When repairing and dismantling, just unscrew the 8 M16×40 bolts on the outer ring of the end cover, that is, separate from the box, then unscrew the 8 M16×40 bolts in the inner ring and remove the end cover. The large bevel gear shaft system can be removed from The upper part of the reducer is completely removed, which brings great convenience for maintenance and repair. A new tapered gear tooth system and a reliable sealing structure are selected.
Vibrating Grizzly Feeders are engineered to combine the functions of feeding and scalping into one unit, reducing the cost of having two separate units. Vibrating Grizzly Feeders are mainly used in a primary applications feeding a primary crusher. The Vibrating Grizzly Feeder provides a continuous feed rate under a variety of loading and material conditions. Vibrating Grizzly Feeders are designed to take heavy shock loads from trucks, shovels and loaders. This type of feeder can be used in quarries, recycling, industrial processing, mining, and sand and gravel operations, as well as in a wide range of processing industries.
How Vibrating Grizzly Feeders Work
The Vibrating Grizzly Feeder consists of a pan section at the feed end to receive and start segregating the material. The discharge end consists of a grizzly section with openings that allow the undersized material to pass before discharging into the crusher. The feeder is mounted on springs and vibrated via a mechanism located underneath the feeder pan, protecting it from misfed material that fails to reach the feed hopper. The vibration force is angled to the feeder, pointing toward the discharge end. This action of the vibrator forces the material toward the discharge end while segregating the material, causing the finer particles to move toward the bottom of the load.
As the material travels to the grizzly section, the finer material settles to the bottom and passes through the openings in the grizzly. This bypassed material decreases the amount of material going into the crusher, reducing the size of the crusher required as well as the wear inside the crusher. The bypassed material can be combined with the material going through the crusher on the under conveyor. This prescreened material protects the under conveyor from the impact of the material exiting the crusher. The prescreened material can be segregated as a product, or it can be discarded if the fines in the material are a contaminate.
