ABSTRACT
Hammer crusher applied in cement plants, power plants, and other department in great quantities, so it has a broad prospect and design experience to draw lessons from. The essence of its design is, after complete the overall design scheme, it refers to the various main components design, installation, positioning, and intensity and the experiment was carried out for inpidual parts. And, in the relevant project life extension of hammer head more detailed analysis. In the design of various components, including the selection of materials, the determination of size, processing, molding process, and cooperate with other parts of the requirements, etc. In the strength check is to use the related formula, to analyze the dangerous parts, look-up table, drawing and calculation, etc. Work on installation, and then to the whole process and all aspects of the inspection after work, both to the problem of device maintenance, insurance, etc, finally, the machining precision of the two main parts, choice of tolerance is analyzed, in order to ensure the reliability of the final design and crusher the efficiency.
Keyword： Hammer crusher, hammer, tolerance, strength.
