The PCX series fine crusher combines the advantages of the third-generation fine sand making machine, hammer crusher, impact crusher, and impact sand making machine. It is a fine sand making machine with large feed particle size and small discharge particle size. The machine adopts a large arc-shaped crushing chamber and utilizes the principle of "stone hitting stone" self crushing. The crushing chamber is a screening chamber with a grate gap. The fine crushing hammer developed by our company has achieved low-cost operation of the fine crusher.

1. The device has stable and reliable operating performance, simplified process, simple and reasonable structure, and is compact, making it easy to replace parts and maintain.
2. Transforming from tertiary crushing to secondary crushing, with high production capacity, long service life of hammer heads, and environmental protection and energy conservation.
3. A unique high chromium plate hammer with a distinctive structure, a unique counterattack lining for breaking hard rocks, a unique inertial impact balancing device, and a unique and easy disassembly and maintenance window. The particle size of the discharge can be adjusted, simplifying the crushing and sand making process.
4. The fine crusher has a 30% to 50% higher yield than traditional sand making machines of the same scale (with a yield of ≤ 5mm accounting for over 85%).
5. The fine crusher saves 50% to 70% of electricity compared to traditional sand making machines of the same scale (produced with just one motor).
6. The fine crusher produces sand and stone materials in a cubic shape with strong compressive strength, suitable for standard building needs (needle shaped, less flaky).
7. The maintenance of fine crusher equipment is reduced by 50% to 60% compared to sand making machines of the same scale. (Vulnerable parts can be purchased locally)
8. The supporting jaw crusher directly forms a sand production line, which can eliminate the need for impact crushing and sand making machines, and reduce investment costs

The material enters the cavity and falls onto the high-speed rotating hammer head. Through the interaction between the hammer and the counterattack plate, the material is initially crushed in the hammering zone. After multiple high-frequency repeated hammering and counterattacks, the material descends onto the middle partition, forming a pile up and sliding, falling onto the high-speed rotating lower rotor's feeding tray, and then being thrown into the counterattack plate at high speed for collision, falling, and forced to counterattack, break, and grind by a mobile plate hammer. Therefore, the material undergoes multiple composite crushing, scouring and grinding during its self weight falling process, thus achieving the effect of fine crushing.
