V. Process Plan Description:

This machine adopts an integrated design of automatic feeding, crushing, and classification, completing the crushing and classification processes in one go. The equipment has a simple structure and occupies minimal space.

1. **Hopper and Automatic Feeding System**: After materials are poured into the hopper, they are transported to the crusher inlet by an electric auger. The auger motor is controlled by a frequency converter, enabling automatic feeding and adjustable feeding volume.

2. Grinder: Model CR600; mainly consists of a grinding section and a classification section:

After the material enters the crushing zone, under the action of high-speed impact hammers and toothed plates, intense collisions, friction, and shearing occur, resulting in ultra-fine crushing of particles. The crushed material then enters the classification zone, where, under the action of the classifier, qualified materials are promptly separated and sent to the next stage for product collection, while materials that have not reached the required fineness continue to be crushed in the crushing zone. By adjusting the rotational speed of the classification turbine, products with different fineness requirements can be produced. The speed adjustment is achieved by controlling the frequency converter in the electrical cabinet, which is convenient and reliable. The crushing fineness is adjustable within the range of 120-600 mesh. The crushing chamber and classification chamber are cooled using water-cooled jackets. Since the material enters the crushing chamber with the airflow and is discharged out of the machine with the gas after qualification, the crushing temperature can be reduced. The main crushing machine is controlled by a frequency converter, reducing the impact of high-power motors on the factory's power grid.

3. Cyclone Collector:

The cyclone collector is mainly composed of several parts, including a cylindrical body, a conical body, a top cover, an intake pipe, an exhaust pipe, an ash collection hopper, and a pneumatic discharge valve.

Its working principle is as follows: when the dust-laden gas enters the outer cylinder at a high speed along the tangential direction from the intake pipe, the airflow changes from linear motion to circular motion. During this rotational motion, the solid particles experience a centrifugal force far greater than that of gas molecules, and the difference in centrifugal force is utilized to achieve gas-solid separation.

Determination of the main parameters of the cyclone collector:

Based on the determination of the parameters of the aforementioned jet mill and secondary classifier, the basic value of the system air volume was established. To achieve the collection efficiency of the cyclone collector**, a semi-circular spiral inlet cyclone collector was adopted, with the wind speed inside the cylinder body ranging between 3.5 and 5 m/s and the inlet wind speed ranging between 18 and 23 m/s, thereby determining the cyclone collector.

4. Electro-pulse dust collector: Mainly composed of the cylinder, pulse controller, pulse valve, back-flush pipe, filter bag, and cage. The fine powder not collected by the cyclone collector enters the baghouse dust collector with the airflow, adheres to the filter bags, and is filtered out. Under the action of high-pressure back-flush air, it is shaken off and collected at the bottom of the hopper, then discharged through an automatic discharge valve to obtain a first-grade product. The clean air is discharged through the fan, with a dust emission concentration of ≤35 mg/m².

5. The entire set of equipment is centrally controlled by a single electrical cabinet, offering high automation. It is convenient and reliable to operate, with the crushing motor, grading motor, and feeding motor controlled by frequency converters, and utilizing a PLC and color touch display.

6. The entire production line operates under negative pressure created by the induced draft fan, ensuring no dust leakage and providing an excellent working environment.
