Spring Two Roll Mining Crusher Machine Large Roller 20-40 TPH Heavy Welded Frame
Meta Description
2PGT800*600 is top-tier specification of spring type 2PGT roll crusher series, with maximum roller dimension among spring models, dual 22kW drive motors. Full parameters: feed particle size ≤30mm, adjustable discharge 1-20mm, hourly production 20-40 tons. Enlarged roller size greatly improves processing stability under full feeding volume, matching large automated crushing lines. Oversized spring groups provide ample buffer stroke for heavy impact loads. Most clients install this model as tertiary crushing equipment after jaw crusher and cone crusher to produce high-quality manufactured sand with low flaky content. Its robust frame adapts harsh open-air quarry operating environment.

Working Principle
Large-size rollers powered by twin 22kW motors perform high-volume extrusion crushing. Heavy-duty compression springs absorb huge instantaneous impact caused by dense incoming hard stones or stray metal pieces, avoid permanent deformation of roller assemblies. Spring tension adjustment controls roller gap to obtain required 1–20mm granularity. Extended roller length ensures uniform material distribution, lowering local roller wear in high-output production scenarios.
