One roll is fixed while the loose roll is spring loaded to minimize shock loads and damage to the crusher during a stall, resulting from non-crushable material, mostly tramp steel, being fed to the crusher. The loose roll position can be adjusted using the adjusting spindles when product size needs to be altered or fine-tuned or when adjustment is required to compensate for wear. The loose ...(PDF) PARTICLE-SIZE ANALYSIS Particle-Size .Academia.edu is a platform for academics to share research papers.Optimization of particle size distribution in .First, the effects of roll gap on the cumulative size distribution were calculated at a roll teeth of zero, as shown in Fig. 8(a); subsequently, the effects of teeth length were also conducted under a fixed roll gap of 75 mm, as shown in Fig. 8(b).
