The Coal incline screen is driven by 2 motors through the triangle belt, driven by the end of the transmission device through the synchronous belt, drag 2 groups of vibrators rotate in the same direction, eccentric block generated centrifugal force on the screen box, the screen box for circular or approximately circular vibration, the material on the screen surface constantly flip and loose, so that the material less than the sieve hole through the screen, Material larger than the sieve is discharged through the discharge nozzle to complete the grading operation.
Coal incline screen includes: screen box, screen plate, vibrator, transmission device, damping spring, screen frame support, motor, motor support, accessories, etc.
Feature:
1. In the design, we should strengthen the optimization design of process connection, material transfer and other links, avoid the problem of "running, taking, dripping and leaking" of materials, eliminate the secondary dust, so as to achieve clean production.
2. Adopting new, reliable and practical process equipment and "three electric" equipment, the level of technical equipment has reached the advanced level of the same type in China.
3. Design requirements system safety, reliability, stable operation, energy saving and consumption reduction.
Inclined screen adopts cylindrical eccentric shaft exciter and eccentric block to adjust amplitude, easy to operate.
4. Screen surface inclination: select 25° inclination Angle, in the design inclination Angle can make the material to obtain the best running speed, so that the material is screened quickly and evenly filled with the whole screen surface, optimize the material flow, and effectively improve the screening efficiency.
5. Coal incline screen vibration intensity 5g, in the vibration intensity, the material thrown up generated inertia force can overcome the bonding force of the material and the screen, the relative motion speed between the material and the screen is accelerated accordingly, the material group loose after less than the size of the screen and the screen contact probability is high, so as to improve the screening efficiency, minimize the probability of plugging.
6. Coal incline screen vibration frequency: using the best vibration frequency of 780r/min, under the action of the vibration frequency, screen machine can maximize its advantages, so that the material to achieve the best stratification effect, so as to achieve the best screening efficiency.
