Broken machinery usually can be divided into six categories, with the exception of hammer crusher and roll crusher, other common crushers in the sand field are pendulum and vertical shaft (vsi)pendulum jaw crusher is the primary crushing equipment pendulum jaw crusher demarcates the specifications on its feeding port's length and width of the calibration, basically according to standard manufacturing, domestic industry manufactures about eight kinds of specifications crushing products the major international manufacturer's products have more specifications in the recent 20 years, in view of the pendulum jaw crusher movement of four connecting rod mechanism on design theory has a lot of progress for example: the crushing cavity two-way rodent angle, short cubits board angular, reduce the transmission angle and eccentricity, foreign companies provide products already often use these validated advanced design theory to improve product performance and reliability in use our domestic manufacturers for a variety of reasons the advanced design theory little, its main products are almost before the 1970 s finalize the design product, is wear-resistant materials, (such as high manganese steel) and important fittings (such as spherical roller bearing), and other domestic foundation piece, the service life is lower than the international advanced level of the same kind product in addition, the main processing and assembling for years to come also is little change, such as bearing hole, of the bearing assembly process and frame of the processing of the processing and assembly, etc.
The quarry crusher wheel axle u0 bolts without locking nut and u0 type bolt quantity is insufficient, will make the reliability of the drag reduction.Pull rod material specification, using the drag rod pin, a wheel shaft of main components and ninety's product is reduced obviously, and there are no other supplementary measures to strengthen.
A portable rock crusher for sale launched by hxjq machinery can be classified into wheel-type and crawler-type mobile crushing plants.
Several adjustable crusher parameters, such as eccentricity, speed, cavity, feed material level and setting allow selective crushing.Together with the integrated automation system, the mx provides maximum utilization of the wear parts resulting in extended maintenance intervals.It means that people need to spend less time near the crusher and will therefore be less exposed to dust, noise and moving parts.
Method: when replacing the hammer, try to use a hammer with the same weight and the same old and new level on one circumference.In addition, if the bearing is damagedand the anchor bolts are loose, the vibration of the hammer breaker is also large.if there is vibration during working, the hammer crushers must be stopped for inspection.It cant work with a breakdown, otherwise, it will cause more damage to the hammermills.
The single roll crusher, with its 6:1 ratio of reduction, is ideal for reducing large feed lumps to a medium product size while producing a considerably lower percentage of fines.The minimum product sizing of a single roll crusher is generally limited to 2-3.The crushing is carried out between the full width of the extra-long curved crushing plate and the low-speed crushing roll.The curvature of the crushing plate provides an ample throat opening to capture large irregular feed lumps.The replaceable crushing plate tips or liners are slotted to intermesh with the roll teeth to produce a cubical product and effectively reduce slabbing.
