Design Optimization of Hammer Blade Crusher to Improve the Crushing Performance

China is a large agricultural country, each year will produce number of straw. The recycling straw to China's development and environmental protection are very helpful, the mainly energy, fertilizer, feed several uses, different uses need crushing fineness, so adjust fineness can improve rate This paper on impact factors for focuses theoretical analysis study affecting crushing, provides general design plan chamber.Firstly, effect hammer sieve gaps pulverisation studied changed by changing gaps. blade material, structure, arrangement, distribution density speed studied. Study aperture size arrangement sieve. material in process generated "ring flow layer" mechanism, shape chamber structure destroy performance crusher.Secondly, according production requirements mill, screen plate designed selected, analysed statically using Ansys, rotor modally, complete model designed, three-dimensional built SolidWorks.Finally, after simulation calculations, headquarters reasonable. An adjustable clearance was achieved, reducing costs improving efficiency pulveriser crushing.
