Rotary Screener

Introduction to rotary screener:

1) Rotary Screener is a commonly used equipment in the production of compound fertilizer, which is mainly used for the separation of finished products and returned materials, and also can realize the grading of products, so that the finished products can be classified evenly.

2) Rotary screener is composed of five parts: drum, frame, funnel, reducer and motor. Materials from the inlet into the drum, on the one hand, with the drum rotation and be screened, on the one hand, the large size of the material along the slope of the drum flow forward, through different mesh screen mesh gradually be screened out.

3) The materials fall into their respective funnels after being screened out, and then they are transported out manually or sent to the finished product pile by self-flow. The machine adopts combined screen mesh, which is convenient for maintenance and replacement. With simple structure, convenient operation and smooth running, it is an ideal equipment for compound fertilizer production line.

Rotary screener working principle:

1) Rotary screener through the gearbox type deceleration system on the equipment center to implement a reasonable rotation of the separation cylinder, the center of the separation cylinder is composed of a number of circular flat steel ring composed of screen, the center of the separation cylinder is installed with the ground plane is tilted state.

2) In the work of the material from the center of the separation cylinder at the upper end into the cylinder mesh, in the process of rotation of the separation cylinder, the fine material from top to bottom through the circular flat steel composed of screen mesh intervals to be separated, the coarse material from the lower end of the separation cylinder discharged into the crusher.

3) The equipment is equipped with plate type automatic sieve cleaning mechanism, in the separation process, through the relative movement of the sieve cleaning mechanism and the sieve body, by the sieve cleaning mechanism on the sieve body for continuous “combing”, so that the sieve body in the whole working process is always kept clean, will not be affected by the sieve holes clogging sieving efficiency.

Advantages of rotary screener:

1) Efficient screening: the rotary screener adopts rotating drum and multi-layer screen design, which can continuously and efficiently screen the materials and improve the screening efficiency. At the same time, the different apertures of the screen mesh can be screened more finely according to the needs of the material to ensure the accuracy of the material.

2) Widely Adaptability: the rotary screener is suitable for screening work of various solid materials, including materials from ore, coal, building materials, metallurgy, chemical industry and other industries. Whether it is wet or dry materials, whether it is powder, granule or block, tumbler screening machine can efficiently complete the screening task.

3) Low energy consumption: the rotary screener adopts the motor to drive the drum rotation through the reducer, the whole screening process can realize continuous operation, low energy consumption. At the same time, the design structure of the drum and the reasonable choice of screen mesh can also save energy consumption.

4) Simple structure: the structure of the rotary screener is relatively simple, easy to operate and maintain. The reducer and drum adopt separate structure, which is convenient for replacement and maintenance. The screen mesh is equipped in the screen frame, which can be easily disassembled and replaced.
