Rhyolite crusher price in Brazil

Infrastructure foundation wall and the wall should be disturbing force in a direction parallel to the crusher, the wall thickness ratio at this time should not be greater than 6; such as a wall perpendicular to the direction of disturbing force, its high-thickness ratio of not more than 4. When meet the above requirements, the wall can be constructed of reinforced, otherwise shall be calculated reinforcement. Foundation of massive volume of less than 40m³ in general may not be reinforced, structural steel configuration only weaken parts of the hole or opening and the top surface of the actuator. Wall basis and foundation of massive cantilevered portion of the base wall and roof beam frame basis are calculated should be reinforced.

Dynamic calculation includes a base set of calculation from the maximum amplitude vibration frequency and amplitude, top of the foundation shall not exceed the allowable value of existing norms. When two or more crusher setting on the same basis, disturbing force and torque whichever scrambling absolute value sum, calculated by multiplying the amplitude reduction factor of 0.75 can. For the calculation results can better meet the actual situation must be carefully chosen foundation stiffness and dynamic computing model. Higher than the wall thickness of less than or equal to the base wall 4, according to the basis of massive computing power. In addition, all should be calculated on the basis frame. To avoid the crusher may start and stop the resonance occurs, the base should be set higher than the natural frequencies of the crusher operating frequency.
