Coal block double roller crusher, for the medium processing demand of 100-200 tons per hour, it is recommended to use a light double roller crusher, the key configuration is as follows:
1. Basic parameter design
Processing capacity
Rated processing capacity: 200 tons/hour (adjustable to 100 tons)
Feed particle size: ≤300mm, discharge particle size: 10-50mm (hydraulic adjustment through roller spacing)
Applicable materials: bituminous coal/lignite with hardness ≤3 level
Mechanical structure
Roller diameter 800mm×roller width 1200mm, surface adopts staggered tooth design
Motor power: 2×55kW (frequency control, energy-saving mode can reduce load by 20%)

2. Core considerations for selection
Wear-resistant configuration
Roller surface surfacing wear-resistant welding rod (hardness HRC58 or above)
Quick-detachable tooth plate structure, single replacement time ≤2 hours
Continuous operation guarantee
Equipped with oil bath bearing box, temperature control alarm threshold 85℃
Spring buffer device overload protection, reset time <5 minutes
3. Economic comparison
Model 2PG0806 double roller crusher, processing capacity 150 (t/h) power 2×45kW
Model 2PG1008 double roller crusher, processing capacity 200 (t/h) power 2×75kW
It is recommended to give priority to the 2PG1008 model and install the intelligent lubrication system, which can reduce the annual maintenance cost by 18%.
