Spring Type Double Roll Mining Crusher With Larger Roller Diameter And Dual Motor

2PGT600*400 is mid-range spring double roll crusher adopting asymmetric dual motor power (11kW and 15kW), specially optimized for coal, coke and medium-hard stone crushing. Key parameters: max feed ≤30mm, discharge adjustable 1-20mm, hourly capacity 13-35t/h. Larger roller diameter improves crushing force for coal gangue and medium hard rock. Independent spring assemblies for each roller absorb impact loads separately, promoting operational stability. Uneven motor power design matches differential roller rotating speed, creating shear effect besides extrusion to raise crushing efficiency for coal materials. This model is popular among coal washing plants, medium quarry sand production lines.

Two rollers driven by different power motors rotate at matched differential speed, generating extrusion and shear force to break coal and stone materials. When oversize hard debris enters the cavity, springs compress to expand roller gap for debris passing, then rebound back to working position. Operators adjust spring tension to control roller gap to obtain 1–20mm products. Differential rotation reduces sticking issue of wet coal on roller surface, ensuring stable throughput during rainy humid working conditions.

1. Differential dual motor design brings shear + extrusion composite crushing effect, higher efficiency for sticky coal raw materials
2. 13-35t/h capacity meets medium scale coal yard and sand plant production demand
3. 1-20mm wide discharge adjustment range, can produce fine sand, medium aggregate for different usage
4. Independent spring buffer for each roller greatly lowers roller damage probability under irregular feed
5. Adapt to wet coal, no frequent roller blockage compared with equal-speed roll crushers
