Ore crushing, railway, highway, and construction industry artificial sand and gravel production.
Product Description
2PC double-rotor hammer crusher adopts parallel double-rotor structure (speed 600-1000rpm), equipped with high chromium alloy composite hammer head (life ≥ 4500 hours) and hydraulic linkage adjustment system, to realize the double-rotor differential reverse rotation, synchronous completion of coarse and fine crushing. The maximum feed size is ≤200mm, the processing capacity is 30-300t/h, the finished product size is stepless adjustable from 5-50mm, and the content of needles and flakes is <8%. Intelligent monitoring module detects the rotor balance, bearing temperature and vibration amplitude in real time, dynamically adjusts the distance between the two rotors (20-150mm) and feeding speed, and protects the machine from overload by shutting down within 0.3 seconds, reducing the failure rate by 50%. Hydraulic open box design (5 minutes quick start) to support the hammer head group overall replacement, modular grate screen plate (gap electric adjustment) to adapt to the needs of multi-stage particle size, -25 ℃ low-temperature anticondensation lubrication system and air-cooled cooling channel to protect the continuous operation. Suitable for limestone, gangue and construction waste recycling crushing, single ton power consumption as low as 0.7kW-h, optional pre-screening or diesel/electricity dual-power drive, the comprehensive production capacity increased by 40%, the return on investment cycle shortened to 8 months.
How to choose suitable Double Rotor Hammer Crusher machine?
1: Independent dual drive system: the dual rotors are controlled by independent motors and frequency converters (power 2×22-132kW), supporting 0-20% speed difference dynamic adjustment, precisely matching the material hardness, and increasing the crushing efficiency by 30%;
2: Heavy-duty bearing protection: four sets of spherical roller bearings + labyrinth seal + grease automatic compensation, shock load resistance increased by 50%, life ≥ 30,000 hours, suitable for high dust working conditions;
3: Energy feedback and energy saving: rotor braking kinetic energy is converted into electric energy and fed back to the power grid, the power consumption of tons of material is reduced by another 15%, and the annual saving
of electricity cost is over 200,000 yuan (based on 1,500t/h production capacity);
4: Multi-scenario modularization: optional detachable pre-screening rollers (to screen out soil/fines) or metal detection stop module, suitable for mining, solid waste recycling and mixed aggregate crushing, finished product
qualification rate ≥ 97%;
5: acoustic noise reduction design: the outer cover of multi-layer damping sound insulation layer (operating noise ≤ 85dB), to meet the EU CE noise standards, fearless city environmental restrictions.
How is works
The material enters the crushing chamber after pre-screening, the parallel double rotors (speed 600-1000rpm) rotate in reverse with differential speed, the upper rotor coarse crushing (hammer head linear speed 35-45m/s) crushes the large pieces of material, and the lower rotor fine crushing (45-55m/s) with the adjustable impact liner for the second impact grinding to realize the “Step crushing. Finished products are discharged through double-layer grate screen (gap 5-50mm electrically adjustable) for grading, and over-limit materials are recycled for crushing by return system. Intelligent center monitors the load difference of double rotors in real time (accuracy ±2%), and dynamically adjusts the speed difference (0-20%) and feed volume to ensure uniform particle size (needle flake <8%). Hydraulic linkage system synchronizes the adjustment of double rotor spacing (20-150mm), adapted to wet materials, sticky materials, anti-clogging design. Modular hammerhead group (single group replacement in 15 minutes) and grease automatic lubrication (-25 ℃ operation) to ensure continuous operation, processing capacity of up to 1,500t / h, a single ton of power consumption of 0.7kW-h, suitable for granite, construction waste and other highly mixed materials and efficient crushing.
