The rotary-disc feeder is a widely used continuous volumetric feeding device. It leverages the flowability of materials, using a rotating disc and an adjustable discharge plate to scrape material from the receiving container and convey it to the receiving equipment. It is suitable for a variety of non-cohesive materials with poor flowability.
This machine operates smoothly with low noise, features a high feed rate, thick material layer, and large feed capacity. The feed rate is continuously adjustable. The steel-wire-core, double-sided, anti-tear conveyor belt offers excellent impact resistance and tear strength, with a typical service life of more than three years.
The YAH circular vibrating screen uses an exciter as its vibration source, and the screening unit consists of an exciter, a screen box, vibration-isolation devices, and a transmission mechanism. The vibrating screen features a rectangular screen surface mounted on the screen box. Under the action of the exciter, the screen box and screen surface generate vibrations with circular, elliptical, or linear trajectories.
The crusher is driven by two electric motors that transmit power through reduction gears to rotate two toothed rollers in opposite directions. When material enters the crushing chamber through the feed inlet, the two toothed rollers, equipped with helical teeth, first screen the material; particles that meet the required size pass between the teeth and fall into the discharge chute. Larger pieces of material are broken down by the splitting, shearing, and tensile forces exerted by the roller teeth and are discharged through the outlet.
Screening and Crushing Machine
The Jinfen crusher consists of a screening system and a crushing system, and can be installed in conjunction with underground coal mine transfer machines and self-propelled tail units. It performs screening prior to crushing, thereby increasing the lumpiness of the material and extending the service life of the crushing system’s toothed rollers.
Drive configuration of the coal slurry crusher: single-drive, with synchronous gear transmission. The motor drives a reducer to increase torque, which is then transmitted via synchronous gears to the dual shafts. The dual shafts rotate, and cutting blades mounted on the shafts shear the coal slurry, breaking large chunks of coal slurry into smaller pieces. Meanwhile, stirring blades on the shafts agitate the material, ensuring uniform mixing and distribution.
