The Design Of The PFK-1212 Impact Crusher overall
Abstract
Impact crushers are applied to such each department as the cement plant , power plant ,etc. in a large amount, so its design has an extensive prospect and experience that can be used for reference. Its design essence is, formerly after total conceptual design, a design which points each main spare part , question of installing and making a reservation etc., and carry on the intensity to check and test to the specific part, and in relevant thematic parts, analysis of comparing question that the life-span of very beginning of the hammer lengthens in detail . In the design of each spare part , should include the choice , sureness , demand processed , structure craft satisfactory of the size of the material , and the demand for cooperating with other parts, etc.. When the intensity is checked , should use relevant formula , carry on the analysis of the dangerous position, need to check form , mapping , calculation ,etc.. Then to to install , work course , work situation after predict that carries on more overall inspection whole, give consideration to the question in such respects as maintaining and safety ,etc. at the same time . Finally , choose to analyze in machining accuracy , public errand to two groundwork parts, economy and dependability that the breaker said as to ensure is designed finally.
