PFC series composite energy-saving fine crushers are the latest generation of high-efficiency crushers developed by our company. It combines the advantages of existing hammer crushers, counter crushers, and impact crushers, and adopts a special chamber design, especially the hammer head, which uses the extremely wear-resistant "2021" special wear-resistant material, making the equipment have the advantages of fine discharge granularity and long service life of wear-resistant components. After being promoted and used, it has gained significant economic benefits for users.

"Stone hitting stone" crushing:

The PFC series composite energy-saving fine crusher uses a large curved crushing chamber and the principle of "stone hitting stone" self-impact crushing. Material suspended in the crushing chamber is in high-speed motion, and the subsequent incoming material is always in a state of "mutual collision and friction", making about 80% of the material fracture and crush along its own microcracks. After the material is broken, there is intense "rubbing and grinding" between the particles, and most of them become powdered, resulting in excellent crushing effect.

The crushing chamber is a screening chamber with a grille slot. In the crushing chamber, a large amount of material enters from the inlet, and the rotor rotates at a high speed, so the crushing chamber is always in a positive pressure state. The qualified powder material is rapidly discharged from the grille slot to the outside of the negative pressure crushing chamber. Due to the above two characteristics, the harmful work of wearing hammers and plates that is common in hammer crushers is basically eliminated, reducing metal consumption greatly, the service life of hammers and plates is multiplied, the rated power of the motor is reduced by about one-third, and the cost performance is greatly improved.

Working principle:

As shown in the diagram, after the material enters the machine body, it collides with the high-speed counterclockwise rotating hammer head, and the large pieces of material are immediately shattered by the impact of the hammer head. The crushed material flies to the counter plate at high speed and undergoes the second collision and crushing. The rebounding material collides and crushes with the subsequent flying material. After the material is crushed in the first chamber, it enters the second and third chambers for repeated crushing, and is finally filtered and crushed by the discharge grille, and the required material is discharged from the grille slot. Coarse material returns to the first chamber for re-crushing.

Specifications and technical performance:

Structural features:

(1) Adopt a three-chamber curved crushing chamber to increase the number of material impacts, reduce hard squeezing and friction, and reduce hammer head wear.

(2) The clearance between the counter plate and the hammer head can be easily adjusted, and the discharge granularity can be effectively controlled.

(3) Adopt a deflectable structure, which can prevent hammer head breakage to a certain extent when encountering hard materials.

(4) The PCF50-300 models are equipped with hydraulic devices, which make maintenance more convenient.

(5) The outlet of the grille is equipped with an iron discharge door. If a piece of iron or hard material cannot be crushed, it can be discharged through the iron discharge door to protect the machine parts from being crushed. However, this cannot replace the iron remover.

(6) The clearance between the left lining plate, the lower counter plate, the grille, and the hammer head can be adjusted according to different requirements for the finished product.
