Rod-type feeder and feeder introduction of commissioning and maintenance
Rod-type feeder is a new feeder, in the production process, can the massive, granular materials from storage silos in uniform, regular, continuous given to the affected device
in the gravel production line crushing machinery for continuous uniform feeding, and coarse screening material, widely
Used in metallurgy, mining, electricity, building materials, chemicals, machinery and other industries crushing and screening operations.
GZT Series rod vibration feeder has five specifications for crusher evenly before feeding bulk materials. Particularly suitable for ferrous or nonferrous ores, building stone
crushing feed before use. industrial belt conveyor
1 working principle and structural characteristics
GZT Series Vibrating Feeder new vibration motor, the series vibrating feeder for coarse crusher evenly before feeding, and because of the role of bar screen surface, but also to
get rid of dirt and other fine materials, reaches a pre-screening the function can be improved crushing capacity.
The new series of vibrating feeder motor or exciter excitation, frame ring groove rivet, manganese steel manufacturing guard and rods, solid structure, high strength, impact
resistance, abrasion resistance, easy maintenance.
2.GZT Series Feeder rod style of the structure analysis
GZT Series rod vibration feeder by a rotatable disc, guide sleeve and the blade materials and other components. The material within the hopper through the guide sleeve material
deposited on the disc with wear-resistant liner disc rotation, the material scraped by the scraper feed. Regulating blade location or level of material guide sleeve can be
changed material handling conveyor
Variable feeding amount. Disc diameter generally 3 meters below the speed does not exceed 10 rev / min. Disc feeder smooth and reliable operation, adjust the feeding amount is
more convenient, less energy consumption, but the structure is more cumbersome for smaller sticky powder granular materials.
Some of the feeder from the housing and impeller components. This feeder relatively simple structure, small size, light weight, feeding when closed, good for small size and
powdered materials. Casing, the bottom of the inlet and outlet ports, respectively, and silos, by feeding equipment connections. Wheel about a horizontal axis
Material falling into the impeller rotates between the cells in each chamber, with the impeller rotation by a half weeks after discharge into the feeding equipment. Equalizing
pipe can enter the feed zone to go before the high-pressure chamber vent grid, in order to avoid the feeding area can not feed. Impeller diameter of 500 mm below normal, the
speed does not exceed 45 rev / min.
How to debug and maintain vibrating feeder
Since the principle of the feeder is relatively simple, so long as the principle of control over their work and structure, under the guidance of the theory, combined with
practical maintenance experience will be able to do a good job of electromagnetic vibrating feeder maintenance and debugging. Electromagnetic vibrating feeder is a more complete
dual particle orientation bomb forced vibration
Of the system. The entire system operates at low critical resonance, its simple structure, stable, power loss is small, widely used in the cement industry, but for now the use
of some units of view, there are more common improper maintenance, work status is unstable, the use of After a period of time
Delivery of materials decreased significantly and other issues. Plus not correct commissioning after maintenance, resulting in poor stability of the equipment, which seriously
affected the normal production.
Electromagnetic vibrating feeder adjustment, debugging mainly electromagnet core gap adjustment, dual particle spring plate connected group of adjustment, debugging.
Air gap between the electromagnet and the armature core tuning
Electromagnetic vibrating feeder air gap between the core and the armature directly affects the size of the normal operation of the feeder, such as improper adjustment of the
light so that the current increase, the amplitude decreases and can not operate normally, severe collisions will produce core The resulting damage to the core and the coil. So
frequent on the gas
Check and adjust gap is an important condition to ensure operation.
Connect dual particle group to adjust the spring plate
Amplitude of the trough there are two factors: First, the feeder electromagnetic exciting force size, frequency, the second is the feeder's own natural frequency. According to
mechanical vibration resonance principle known only when the feeder with the natural frequency of the excitation frequency close to the electromagnet resonance when the
amplitude of the trough
Dual particle method for adjusting the spring plate group: adjustment of the machine to the air gap adjustment is completed, you can start to adjust the stiffness of the spring
plate group. Loosen overhaul screw, connected to control power, a gradual increase in operating current at the same time, observed in the amplitude of the electromagnetic
vibrating feeder signs
The indicated value. When the current reaches its maximum, and reach maximum amplitude can be set on the top of the spring plate screws slightly loose, then as the amplitude
increases, the current decline, then the spring stiffness is too large, should reduce reed the number of blocks to reduce the stiffness. Instead it should increase the number of
To enhance the overall stiffness. Short as long as the adjustment can be repeated carefully tuned to achieve the best value is to determine the role of the amplitude of
vibration signs point vibration amplitude, measured two lines dividing point is the value of the amplitude values.
