Uesd Limestone Cone Crusher Long Service Life, Adjustable Final Size, Large capacity, Can do Hard Stones, Mutiple Size,Choice of jaw crusher feed size is to look at the principles and discharging grain size of the decision, the Liaoduo large, coarse granularity, the selection of super coarse type or coarse type, whereas the medium and fine type. In calculating the feed size, with the largest open side inlet size multiplied by 0.85 as an alternative feed of dimensions, while the average size of the product is the biggest crushing ratio is calculated by dividing the feed. Jaw crusher feed on grain size distribution, in general, smaller than the closed side of the discharge port of the material must not exceed 10%, if more than 10%, the increase in power consumption, product size becomes . of Uesd Limestone Cone Crusher
Lubrication jaw crusher can often work and timely attention to ensure the normal operation of the friction surface and extend the life of the equipment. Add as 50-70%, the carrying capacity of oil must be replaced every three months, oil change, application of clean gasoline or kerosene carefully cleaned roller bearings. Bracket and bracket pad contact, before oil began to enter the crusher. Steel jaw crusher requires large furnaces for melting the steel mold casting. Now basically used electric furnace, the higher the production process. General by a professional casting plant jaw crusher housing body processing.

Uesd Limestone Cone Crusher Operation Notes:
Cut off operations and emergency stop processing 1, ore crusher All cut off must be ruled out before stopping. 2, cut off should be the first stop to the mining system (ie trough feeder). 3, vacuum cleaners and water system before stopping after 5 minutes. 4, the following conditions should an emergency stop: (1) The main shaft bearings or moving the jaw abrupt temperature exceed 80 ℃, the surface phenomenon is touching the back of the bearing can not be sustained for a second time. (2) before or after the thrust plate fracture. (3) belt loose bolts or other transmission parts likely to break when flying wounding. (4) Motor smoke "sweep bore."
Maintenance & Attention
Jaw crusher maintenance focuses rack chassis is the foundation since broken jaw, and only stable foundation in order to protect a broken jaw safe and efficient operation. According to Tian Rong machine broken jaw after-sales service for many years of experience, we believe that broken jaw rack routine maintenance parts that require special attention is not much, but the site operator must attach great importance. Usually broken jaw rack problems are caused by related parts, specifically summed up includes the following aspects: ① severe beating rack jaw broken, loose or broken bolt: tight bolt or replace broken bolts; ② fly counterweight sheave position deviation: Remove the fly sheave shaft cover plate, unscrew the fly, Lunzhang sleeve slot bolts, alignment fly counterweight sheave block position, and then sets up tight tight bolts; ③ host foundation is not solid, no isolation measures: jaw crusher reinforced base, padded sleepers or rubber, etc; ④ jaw broken rear of the chassis to produce percussion, rod not tightened, toggle plate and moving jaw hit the bracket to adjust the seat cushion: fastening rod; ⑤ lever and move the lower jaw hooks friction: a mechanical device to check whether the failure of the spring tension, such as failure of the replacement spring, adapter rod or retightening spring; ⑥ mutual impact between the spring and spring seat: the spring seat in place and tight tie rod nuts to the proper position.
To Choose a Right Uesd Limestone Cone Crusher
Composite hammer, while having a higher life, but its casting and heat treatment process is complex. For this reason, in recent years developed a variety of low-alloy steel hammer, there 40CrMnSiMoRe been promoting low-alloy steel hammer. 40CrMnSiMoRe steel alloying elements, low production cost, simple process, you can get the required mechanical strength through the appropriate heat treatment. After analysis of the health of the hammer and experiments on the crusher, confirming the performance indicators in line with the kind of material hammer, hammer can be used as a good material. On the plant hammer crusher, 40CrMnSiMoRe high manganese steel hammer and hammer were worn compared. Test Method is mounted on the two rows of hammer crusher, each mounted in a row, with the machine running, test results: 40CrMn-SiMoRe hammerhead run 21d, the high manganese steel hammer run 14d, due to the two hammerhead wear different lengths, so use to measure the actual length of the wear life of more practical.
