moving jaw crusher evenly placed outside describes 18/10/2011 the country prosperous Heavy machinery according to customers reflect the practice of the Chinese New Year is the successful development of a new type of outside moving jaw crusher evenly placed due to its novel mechanism design and unique structure,Mobile Crusher its excellent performance: low profile, 20% lower than the same model of traditional jaw broken, feeding low height reduced by about 1/3 the height of the broken system, greatly reducing the amount of chamber dug crushing capacity, lining early plate wear low energy consumption, large crushing ratio, high reliability become broken ideal choice.However, in the simplified after the crushing process, with the reduction of the number of broken segment, the crushing ratio of the increase in the processing capacity of the crushing machine to decline.To ensure the processing capacity of the crusher, the development of wide-cavity type crusher is one of the development trend. The body moving jaw jaw crusher crusher weight of large parts, complex structure, mainly by the moving jaw tooth plate seat, side panels, axle tubes and other parts welding withstand the crusher by thrust plates and materials generated strong extrusion pressure, the force situation is more complicated.Moving jaw body running withstand the crushing force of the material of the tooth plate seat bracket shaft tube of tooth plate seat support force and main bearings supporting force. Body for moving jaw model, due to the limitations of the assembly conditions, the small side plate changes leeway while moving jaw tooth plate seat structure is more complex, the heaviest weight, there is considerable scope to modify, so the body moving jaw uniform design focused moving jaw tooth plate base uniform design.Moving jaw tooth plate seat structure is best should be under the same load conditions,cone crusher making the force structure similar status.This can be fixed load conditions to stress uniformity tooth board seat above the minimum as the evaluation criteria to establish the optimization model to optimize the design.For the moving jaw tooth board seat, in the long-term alternating loads, often in a tooth plate seat at fatigue failure.Therefore, it can be based on the fatigue limit stress of the tooth plate Block above tooth plate seat by a certain conversion relationship value obtained i.e. uniformity to define the objective function. Obtained by the finite element analysis in front of a moving jaw body the effect stress cloud can be seen, the tooth plate seat bearing plate and the ribs by a smaller force,stone crushers
most parts of the maximum stress is much smaller than the tooth plate Block yield load.Figure from the structural point of view, the thick and the support of the tooth plate seat carrying Banban tendons Banban thick large room for improvement, intended to optimize the size of manpower from these places,. After the parameter optimization of the teeth of the movable jaw plate seat despite the maximum stress is lower than the allowable stress, the stress uniformity decreases,[jaw crusher:http://www.xb-crusher.com/Crushing_Equipment/Jaw-Crusher.html] however, weaken the strength of the structure, while observing its structure and shape, there are still large changes space proposed by artificial further modifications on the seat of the tooth plate, so that the structure of the tooth plate seat requirements more perfect.The tooth plate seat structure is modified as follows: (1) due to tooth board seat bearing plate board thick by 60mm becomes 35mm, ribs connecting brackets at a smaller force, intends to rib thickness changed 35mm. (2) Since the lowermost transverse central rib stress concentration, the decision where to add a cover, a plate thickness of 30 mm, so that there stress homogenization,Impact crusher where the thickness of the ribs is unchanged, still 60mm. (3) In order to be more conducive to processing, the thickness of the longitudinal ribs is changed from 60mm to 30mm. (4) The longitudinal ribs from the side of the tooth plate distance from 390mm to 405mm.
