In small and medium-sized sand and gravel production lines, hammer crushers with an 80 tph capacity are a common choice. Based on mainstream market configurations, this capacity range primarily encompasses the following three typical models:
1. PCZ Series Heavy Hammer Crusher
The PCZ0808 model features a dual-rotor design with 16 hammer heads and a 55kW x 2 motor. By optimizing the rotor speed (980 rpm) and hammer weight (35 kg per head), it achieves stable crushing of medium-hardness materials such as limestone, with a measured capacity of 75-85 t/h. Its advantage is a one-shot crushing rate exceeding 90%, making it particularly suitable for construction aggregate production.
2. PCX High-Efficiency Fine Crushing
The PCX600 x 800 model is equipped with an adjustable grate system, allowing flexible adjustment of the finished particle size by controlling the discharge gap (10-30 mm). Utilizing high-chromium alloy hammers (with a lifespan of up to 8,000 hours), this model offers a stable production capacity of 70-80 tons/hour when processing hard rock such as granite, while reducing specific energy consumption by 18% compared to traditional models. This model is widely used in metal ore beneficiation pre-treatment.
3. Mobile Hammer Crusher Unit
Some manufacturers integrate the PC400×600 hammer crusher and vibrating screen onto a crawler chassis to create a mobile crushing station. The diesel-powered version (90kW) can maintain a production capacity of 80 tons/hour even in offline conditions, making it particularly suitable for highly mobile operations such as construction waste recycling. Its modular design allows for rapid site transfers, reducing overall investment costs by 30%.
Note when selecting a model: The PCZ series is suitable for coarse crushing of hard materials, the PCX series focuses on fine crushing and particle shape control, and the mobile model emphasizes operational flexibility. Actual production capacity is significantly affected by material moisture content (recommended <15%), feed size (≤400mm), and hammer wear. It is recommended to give priority to models equipped with a hydraulic cover opening device to facilitate quick replacement of the hammer head and screen plate during maintenance.
