Are you confused about jaw breakers ,, First read this simple guide . Next you can choose the right machine . Because we are SBM . We are a famous mining gear factory . Also we give you the best solutions . Therefore you will make more money .
First a standard cavity is a basic shape . It looks like a simple V letter . Next it breaks stones by squeezing . But it has a big problem . So it can choke on huge rocks . Also it has a very small crushing ratio . The crushing ratio is a math thing . It means how small the mineral becomes . For example a big stone goes in . Next a small stone comes out . Thus the ratio is big divided by small . A standard smasher has a ratio of 3 . Because the chamber is too short . Therefore the stones do not break much .
First a deep cavity is much longer . Also it goes deeper down inside . Next the angle is very steep . Therefore the stone falls down much faster . Because gravity pulls it down quickly . So the smasher does not block easily . Also it has a huge crushing ratio . The ratio can easily reach 6 . Next it gives a much higher yield . Yield means your tons per hour . SBM deep cavity smashers are very famous . Thus many mining people buy them .
First let us talk about the drive . A big electric motor gives the power . Next v belts connect to the flywheel . Then the big flywheel spins very fast . Also the eccentric shaft turns around . So the moving jaw goes up and down . Because of this the minerals get crushed . Therefore the machine needs a strong frame . Also speed is very critical . SBM sets the speed to 250 RPM . Why ? Because 250 RPM is the perfect balance .
First you must know the CSS . CSS means Closed Side Setting . This is the gap at the very bottom . Also it decides the final stone size . Next you must understand the OSS . OSS is Open Side Setting . This is the wide gap at the top . Then we have motor power matching . Big smashers need huge motors . Because crushing hard mineral needs big energy . For example SBM matches a 110kW motor . Why ? Because it saves electric bills .
First we cite the Global Mining Journal 2023 . The journal tested many rock breakers . Next they found deep cavities are much better . Because a deep cavity raises output by 20% . Also it saves much power energy . It uses 12% less kW per ton . Why ? Because the falling path is very smooth . Next the wear parts last much longer . Wear parts are the jaw liner plates . Standard plates die in two short months . But deep cavity plates last three months . Therefore you save money on spare parts .
| Data Type Name | Standard Cavity Type | Deep Cavity Type |
|---|---|---|
| Max Feed Rock Size | About 500mm | Up to 600mm |
| CSS Gap Range | From 50 to 150mm | From 40 to 200mm |
| Average Yield Output | Only 100 tph | Over 130 tph |
| Liner Plate Life | Very short life | 20% longer life |
First maybe the feed rocks are too big . Also maybe you use a standard cavity . Because a standard cavity has a bad angle . So the stones get stuck easily inside . Next wet dirt can cause big blocks . Therefore a deep cavity is a good solution . Because the steep shape helps flow . So wet dirt slides right down . Thus you have totally zero stopping time . SBM engineers designed this shape perfectly well .
First you might crush very hard rocks . Hard minerals like granite destroy normal steel . Also a bad CSS setting causes bad rubbing . Because rubbing wears out the metal quickly . So a deep cavity stops this bad rubbing . Next it breaks stones by pure pushing . Therefore the steel plates stay safe longer . Also SBM uses high manganese steel parts . Why ? Because manganese is super hard .
First we have a real case in Africa . The climate there is very hot and dry . Also the mineral is super hard granite . Next the customer needed 200 tons an hour . But their old broken machine totally failed . So SBM gave a perfect new solution . We used an SBM deep cavity jaw breaker . The model name was PEW860 smasher . Next we matched a strong vibrating feeder .
Why did we set CSS to 100mm ? Because the client wanted small output rocks . Next the running data was very great . The output hit 220 tons every hour . Also the electric energy use dropped down . The customer was very happy with us . He said ,, SBM machines are incredibly powerful . Also they save us a lot of money ,, We love SBM service very much .
First we have another case in wet Asia . The weather there rains almost every single day . Next the material is wet sticky limestone dirt . Because sticky rocks always block normal smashers . First we visited their dirty working site . Then SBM made a totally custom plant design . Also we used SBM C6X deep cavity breaker . Why ? Because the deep shape stops any sticking . Next we added a 132kW electric motor .
Why did we use a 132kW motor ? Because sticky wet stones need huge pushing power . Also the final product size was excellent . The daily failure rate dropped to almost zero . The customer gave SBM a great review . He said . SBM helped our factory a lot . Also the installation was super fast . Next SBM service team is the absolute best ,,
First SBM helps you install everything nicely . We send smart workers to your local site . So you have absolutely zero building worries . Next you must check the lube oil daily . Why ? Because oil stops the hot metal friction .
Also check the iron toggle plate often . The toggle plate is a safe break part . Because it breaks if iron falls inside . Therefore keep many extra toggle plates ready . Next tighten the side bolts every single week . Because loose bolts will cause fatal massive damage .
First a deep cavity machine costs slightly more . But it makes much more profit later . Because it yields 20% more crushed stones . Next it saves huge electric power bills . Also it saves long maintenance repair times . Therefore you get all your money back fast . Usually you get it back in six months . Also SBM machines are built extremely tough . Thus your money investment is highly safe .
First SBM is a real direct big factory . We are definitely not a trading middle man . So you get the absolute lowest prices . Next we supply full complete crushing solutions . We design the total plant layout perfectly . Also we provide custom unique design plans . Furthermore we give amazing after sales support . If your breaker stops we fly there . Also we have all spare parts ready . Therefore your rock business never stops running .
First a deep cavity jaw breaker is best . Because it has a massive strong frame . Next it takes heavy crushing pressure very easily . So it smashes hard granite into tiny pieces . Also SBM makes the strongest ones worldwide .
First stop the big machine power completely . Also lock out the main power box tightly . Next use SBM hydraulic tools to push wedges . SBM smashers have very easy hydraulic wedges . Therefore the adjustment takes only ten minutes . So you save much valuable working time daily .
First please check the bottom foundation steel bolts . Maybe the bolts are shaking very loose . Also check the big heavy flywheel balance . Because if wheels are bad it shakes wildly . Next quickly call SBM after sales service team . Then we will repair it for you perfectly .
