Rotary Drum Screening Machine

Introduction of Rotary Drum Fertilizer Screening Machine
Fertilizer rotary drum screening machine is an ideal equipment in compound fertilizer manufacturing plant which is used for separating the finished organic & compound fertilizers and the returned materials that do not meet the quality requirements.

This rotary drum screening machine can also realize the final product rating and classify the end products evenly. This rotary drum screening machine features the modular screen which is easy maintenance and replacement. Our compound & organic fertilizer screening machine, which enjoys a wide acceptance in the world fertilizer market, runs smoothly with simple structure, and is easy to operate, to assembly and to maintain.

Features of Multi-function Rotary Screening Machine
1. High screening efficiency. As it is equipped with plate cleaning sieve, in the screening process, the materials never go to block screen no matter how sticky and wet and miscellaneous the materials are, so as to improve the efficiency of screening equipment.
2. This machine features a dust cover outside the screening bodies, which helps to eliminate dusts thereby, improve the working environment and reduce the noise of the equipment.
3. The screen is made of several circular flat steel and the cross-sectional area is much larger than the cross-sectional area of other separation equipment sieve, which helps to improve the service life.
4. This machine uses shaft pin type coupling gear to transfer driven between the reducer and the working parts of the host, which makes it easy to assembly and maintenance.

Working Principle of Fertilizer Rotary Drum Screening Machine

This fertilizer rotary screening machine consists of cylinder, rack, funnel, reducer, and motor. When it begins to work, the materials are sent into the cylinder through the feed end. With the rotating of the cylinder, the materials are screened. The bigger granular material flowing along the slope of the cylinder to move forward, and the materials are screened through different screens for different purposes. The returned materials will go back to fertilizer crusher for further process, while the finished products are conveyed to fertilizer coating machine, or directly transported to automatic fertilizer packager.
