The rotary sieving machine is common equipment used in the production of compound fertilizer. It mainly used for the separation of finished products and return materials. Zhengzhou Fusmar Machinery is a professional rotary sieving machine manufacturer, this article will introduce this machine in detail.

Rotary Sieving Machine Introduction

This series of rotary sieving machine can realize product grading and evenly classify finished products. The machine adopts combined screen mesh for easy maintenance and replacement. It has a simple structure, convenient operation, and stable operation. So it is the ideal equipment for compound fertilizer production.

Basic Structure

The rotary sieving machine composed of a motor, a reducer, a roller device, a frame, a sealing cover, an inlet and outlet, and so on. The roller unit mounted obliquely on the frame, then the motor coupled to the rotary unit via a coupling through a reducer to drive the drum unit to rotate about its axis.

Features Of The Rotary Sieving Machine

The machine can divide into three parts:

  1. Rack part:The machine frame is welded with excellent carbon steel plate and channel steel. Otherwise, it has passed strict product qualification certification and specific process requirements, which has reached the purpose used by this machine.
  2. Transmission screening part:This part adopts a combined screen, and then it transmitted from the transmission wheel to the main shaft through the coupling. The screen installed and welded on the rolling cage of the main shaft, then, the material enters from the feeding end, and the rolling cage continuously rotates and classifies. Otherwise, the discharging port evenly discharged from the lower side, which effectively separates the finished product from the returning material, thereby improving work efficiency.
  3. Transmission connection part:The motor drives the pulley, the V-belt and the reducer to drive the spindle to rotate, then the transmission reducer and the working part of the main machine all driven through the pin-pin coupling, which is convenient for assembly and maintenance.

Working Principle Of The Machine

The rotary sieving machine performs reasonable rotation on the center separation cylinder of the equipment through the gearbox type deceleration system, at the same time, the center separation cylinder is a screen composed of a plurality of annular flat steel rims. The center separation cylinder installed in a tilted state with the ground plane, otherwise, the middle material enters the cylinder net from the upper end of the central separation cylinder.

During the rotation of the separation cylinder, the fine material separated from the top to the bottom through the screening interval composed of the annular flat steel. And then the coarse material discharged from the lower end of the separation cylinder into the crusher. At the same time, the device has a plate-type automatic cleaning mechanism. During the separation process, through the relative movement of the cleaning mechanism and the sieve body. And then the sieve body continuously combed through the cleaning mechanism. So that the sieve body kept clean throughout the working process. Otherwise, the clogging of the screen will affect the screening efficiency.

Advantage Of The Rotary Sieving Machine

  1. The material is not easy to block the sieve hole.
  2. Smooth operation, low noise, simple structure, convenient maintenance, and so on.
  3. The screening cylinder can close andopen, otherwise, the sealing is easy to close and collect dust.
  4. The machine has high reliability and less one-time investment.
  5. Adopt special screen, high screening efficiency,long service life, and so on.
