Old series cone crusher inside the defects, has aimed at the spindle, contributing to broken shaft accident. Depending on the site from the broken shaft, damage cross-section of analysis and operational issues, and do strength check calculation, that your spindle break the next reasons:
1) not enough spindle intensity: after resistance training 'operator recognize that the most crucial publication of the glaze is named the static strength of persistent anxiety, may not be sustained on a lawn so that the normal broken ridiculed for. Than iron, the damaging portion of the bending stress children, the majority of the material on the limited term service.

2) the impact of overload: within the course, with the not enough spring pressure, the difficult crushing ore, broken machines often have the top beat. Again taken to boost the compression spring means breaking force, to make sure that also increases the force on the spindle. Together the protection of your spring trip is shorter, to ensure that should the spring will be over if the soap breaks the iron status, only regularly complete the spring screw, leaving the plant spindle to stand up to greater load. quartz grinding mill
In addition, caused by uneven lining wear, the goods size becomes coarse and uneven. J m unit force to acquire qualified product size, might be employed in touch the quilt of discharge port level. This card had iron or iron greatly increased many times.
According towards the broken shaft on the reasons, the brand new series, made the examples below improvements.
(1) good new type of the spring pressure, the corresponding variety of the axis with the cries, the generally increased the diameter with the shaft.
(2) to better off-axis perhaps the rounded shape, to raise their quantity surface light stick, will finish the V3 to V6, for you to limit the stress concentration there. Old series, where radius is 10 mm (small). Change following your cone axis with radius tangent to your lower a part of the upper phase while using the cylinder axis. Dotted line along with the height and width of the existing family 1650 brackets breakers, solid line, with zero parentheses following your height and width of 1750 to enhance the crusher.
(3) slow up the spindle as well as the cone of interference with all the body. In order that the spindle and the entire body doesn't happen during operation, loose, demands a certain quantity interference. Greater the volume of interference the greater solid, but will likely increase the stress concentration, reduces fatigue strength on the spindle more severe. mesin pemecah batu
(4) increased shedding tank, will minimize the pressure with; raw power on the blood concentration factor near 30%, the ideal bending moment, pressure, and rounded with all the concentration of negative factors just like fatigue and Ib don't concentrate on within this section.
