The PFL is a vertical compound crusher without a grate bar. Rotor hammers throw the feed against the chamber wall and against the material bed, so reduction is partly impact and partly attrition. The absence of a grate removes the usual cause of blockage in wet or clay-bearing soft rock, and the machine delivers a high proportion of finished sand in a single pass.
Characteristics
- Grate-free chamber — no blockage in wet or clay-bearing feed
- One-pass sand rate above 90% in soft rock
- Single rotor, simple structure; wear parts accessible from the top
- Low installed power relative to output for low-abrasion materials
Application
Manufactured sand from limestone, dolomite, coal gangue and similar materials, and fine crushing where a hammer mill would generate excessive fines.
