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.
Dsmac sand production line mainly consists of vibrating feeder, jaw crusher, sand making machine, vibrating screen, sand washing machine, belt conveyor, electric control panel, etc, and capacity is 50-500t/h.
Trio portable ct30x42 jaw crusher with hydraulic adjustment, reversible jaw dies and 150 hp electric motor drive and drive guard; tf4620 vibrating grizzly feeder with cast adjustable grizzly bars and 30 hp electric motor drive and drive guard; 48" wide x 25 long discharge conveyor with impact bed under feed point, belt scraper mounted under the head pulley, 5" idlers and 15 hp electric motor drive; hydraulic four point leveling system; triple axle suspension complete with access ladder to maintenance platform, access ladder to inspection platform.Equipment #301-0145.
In the ore feeding process, the customers should feed it in a even and reasonable way in order to prevent accidents resulting from too much quantity of ores fed.For this reason, the operational personnel should learn in mind the interlocking device of the feeding transportation equipment and crusher electricity because the feeding transportation equipment can only work on the condition that the crusher machine is started and normally operated.If the jaw crusher stops working, the feeding and transporting links will immediately stop as well.Whether the discharging and transporting links normally work also has an influence on the ore feeding links.If the discharged materials pile up on the bottom of the crushing device, it may be jacked up and severe accident may happen.For this reason, if the crusher is blocked, it should be stopped immediately.
The structuraldesign of fixed jaw crusher is relatively simple, mainly consistingof automaticlubrication system, hydraulic friction clutch,hydraulic connecting road, and thrust plate (as safety devices), overload protection device, hydraulic adjusting device,inclined iron adjusting device, pad adjusting device, transmission mechanism, working mechanism, rack.While the structuraldesign of impact rock crusher mainly consistsof machine shelves, rotors, transmission mechanism, counterattack plate, hammerhead, etc.
Today, two main jaw crusher configurations can be seen from the major equipment manufacturers.They differ based on how the swing jaw moves, though their output is similar.
This professional crusher blog contains crusher basics which focuses on the jaw crusher, hammer crusher, impact crusher, crusher failure, causes, mainly due to the .
5.According to the results of strength and stiffness about the various components of jaw crusher, optimal parameters are set.Then,optimal results of them are found to ensure the performance of the original machine did not fall by optimization module of ansys.So it can provide reference for enterprises to reduce costs and enhance competitiveness.
Lc-27 2.25x3in laboratory jaw crusher reduces 2in (50mm) aggregate, ore and rock materials to a product with 80% passing a no.14 (1.4mm) sieve.Jaw opening easily adjusts down to 1mm minimum to closely control output size.Maximum throughput is approximately 50lb (22kg) per hour at 525rpm.Rate of operation is regulated by the variable speed controller.Jaw plates are high-impact, wear-resistant ar450 steel.It has a 1hp electric motor.Electrical cord and plug are included for operation on 115v/60hz electrical supplies.Variable speed controller can also operate on 220v/50hz power sources with a slight reduction in speed.
When talking about coal crusher, many manufacturers may think of using jaw crusher, but the extrusion principle of jaw crusher does not apply to the making of coal.Its efficiency is often slow and power consumption is often huge and can not effectively use its own hardness properties of materials to carry out self-smash.On the contrary, subject to the constraints of physical stress, it will cause jaw plate working a long period of production and post-state of fatigue and can easily lead to broken phenomenon.
When jaw crusher detects there is iron entering into the cavity, it will reduce the crushing pressure, lower its main shaft, expand the discharging port to prevent jaw crusher from heavy damage.However, in the whole iron discharging process, the damage to the jaw crusher is very large.
The granite is very hard, so the requirement on the wear resistance of the machine is very high.We recommend the big jaw crusher hd125 950*1250 firstly, which can reduce the cost.Then, the cone crusher crushes further and the sand maker will shape the granite particularly and evenly.This guarantees the quality of the finished product.
