1. Features of extractor:
1) Simple construction, light weight, low noise, reliable working, arge feeding capacity, easy installation and maintenance.
2) Use self-synchronization principle of vibrating motor, rapidly start, stable work, smooth and steady park.
3) Feeding trough is small weared because of materials are throwed up and saltantly move forward as parabolic trajectory
4) The higher presion of feeding materials due to the spout can be altered and open and close instantaneous.
2. Working principle of mechanical feeder
Use specially made vibrating motor or two motors to bring along exciter, which drives feeding groove to make periodic linear and reciprocal vibration along the inclined direction in order to complete feeding. When vertical component of feeding groove vibrating accelerated speed is greater than gravity accelerated speed, materials are throwed up and saltantly move forward as parabolic trajectory; Throwing up and falling are completed in a flash. Exciter source constantly excited and feeding groove constantly vibrate, coal in the groove constantly jump forward to complete the feeding.
3. Installation Conditions
1) To assure uniform and stable feeding and prevent materials from self flowing in ingredient and quantitative feeding, feeder should be installed horizontally. For constant feeding of general materials, it should be declined 10 degree to install; For viscosity materials and materials with high moisture content, it should be declined 15 degree to install.
2) Feeder installed should leave motility gap 20 mm, across direction should be horizontal, suspension equipment should be connected flexibly.
3. All bolts should be fastened once specially anchor bolt of vibrating motor and refastened when they constantly run per 3 to 5 hours before dry practice.
4) Two vibrating motors must rotate reversely, timely stopping working to process when there is abnormity on the stability of current and noise.
5) Motor bearing should be filled in once grease per 2 months and should be filled in once grease per month in high temperature season.
