This page shows massive output breakers,, We are SBM factory.. We make these strong machines. Yellow metal rock mining is very hard. The cold Russia winter is bad. However SBM smashers works perfectly there. First read this helpful guide,, Then you will understand the tech. Finally you can contact SBM sales..
First we explain the basic machine,, A rock breaker crush big stones. It is a main reduction tool. It have one fixed mouth die.. Also it has one moving die. The moving part swings back fast. Then it swing forward very hard. Therefore stones gets smashed inside it,, This action breaks yellow metal rocks. Also it crushes very hard ores. Why: Because the pushing force is huge. Next we look at reduction ratio,, Ratio mean input size versus output. A big ratio is extremely good.. It means high working efficiency. Journal of Minerals prints this fact,, They tested many big volume breakers. The exact data shows clear results..
Next let us talk about parts.. An electric motor provide the power. The motor turns a thick V-belt. Then the belt spin a wheel,, This is the heavy iron flywheel. The flywheel holds kinetic energy safely. Why: To keep the turning motion smooth.. Then the middle eccentric shaft turns. This shaft move the big pitman. The pitman holds the moving die,, Therefore the massive crushing force happens. The back toggle plate supports it. It also work as a fuse.. A huge steel piece enters sometimes. The toggle plate snaps quickly,, Why: To save the main steel frame. This is a very clever design..
First you must understand the CSS,, CSS mean Closed Side Setting gap. This is the very small gap. It happens during mouth closing.. CSS controls the final stone size. Why: It stops big chunks falling,, Next you must know the OSS. OSS means Open Side Setting gap.. This is the wide open gap. It happens during mouth opening. The difference is the swing stroke,, Also rotating speed is very vital. Speed means full revolutions per minute.. High speed give big volume output. But it wears metal dies faster. Therefore you need a good balance,, SBM engineers calculates this perfect balance. We use the Bond Work Index.. This special index measure stone hardness. Then we choose the motor power,,
| Model | Max Feed (mm) | CSS Range (mm) |
|---|---|---|
| PEW760 | 600 | 75-200 |
| PEW860 | 720 | 100-225 |
| PEW1100 | 850 | 150-300 |
First many mine owners asks this,, Russia get extremely cold every winter. Ice freezes the wet raw stones.. Then stones stick inside the mouth. Therefore daily production stops completely often,, How do SBM solves this problem? SBM adds a special heating cover.. Also we redesign the mouth shape. We use a V-shaped deep cavity. Why: To let sticky stones drop,, Next we use low-temperature alloy steel. Normal steel become brittle in cold.. Our special steel stays very tough. Therefore the heavy frame never cracks,, Journal of Siberian Mining confirms this. They tested our steel machine frame.. The frame failure rate are zero,,
Next power cost is a pain.. Cold mines uses lots of electricity. Old smashers wastes much kinetic energy,, However SBM changed the wheel design. We use heavier perfectly balanced flywheels.. Therefore momentum is kept much better. This saves 20 percent power daily,, Why: Because wheel inertia do the work. Also we match the motor exactly.. We never uses oversized electric motors. A simple decision tree helps us,, Step one check raw stone hardness. Step two check the feed size.. Step three check the needed output. Then pick the exact motor size,, This lowers the energy bill fast..
Now read about a true job,, A client in Russia needed machines. They owns a yellow rock mine.. The site altitude is very high. First the winter temperature is minus 30,, The raw stone are extremely hard. The compressive strength is 250 MPa.. Next they called SBM for help. We gave them a complete plan,, We supplied one PEW1100 rock breaker. Also we gave them long conveyors.. The raw data showed massive success. Past production was 100 tons hourly,, Now they makes 300 tons hourly. Therefore their daily profit went up..
The Russian client left good feedback,, He said SBM smashers is strong. First the site installation was fast.. SBM workers guided the whole setup. Next the daily production stays stable,, The machine never jam with ice. Also the routine maintenance is cheap.. They only changes oil and dies. The energy use dropped 15 percent,, Why: Because of the smart V-cavity. The client trust SBM brand deeply.. We are a great direct manufacturer. We provide the full custom solutions,,
Next let us discuss strong metals.. The middle shaft take huge stress. SBM uses forged thick alloy steel,, The exact standard is ISO 4321. Why: Because forged steel bends safely.. Also the main frame is massive. We uses thick welded steel plates,, We heat relieve the frame later. This remove bad internal metal tension.. Then the steel frame lasts decades. The mouth dies is high manganese,, Mn13Cr2 is the exact chemical name. This special metal hardens during crushing.. This process is called work hardening. Therefore the mouth dies last longer,,
Let us add more case facts.. The Russia site had terrible weather. The winter wind was 50 miles,, First we checked the feed stones. It have 5 percent wet clay.. This clay make crushing very difficult. Also the site was 2000 meters high,, Thin air makes electric motors hot. How did SBM fixes this issue? We picked a much bigger motor.. Why: To compensate for the thin air,, Next we added a shaking grizzly. The grizzly remove the wet clay.. Therefore the big smasher stay clean.
Next we check the daily money,, Mine owners cares about running costs. SBM tracks the electric energy use.. Normal breakers needs 1.5 kWh hourly. SBM smashers needs only 1.1 kWh,, Why: Because the moving geometry is better. Also the machine failure rate drops.. SBM tracks downtime across all sites. Our average machine downtime are low,, Therefore you crushes more yellow rock. Next we check the wearing parts.. Manganese mouth dies costs money always. But our dies crush 30 percent more,, Therefore your cost per ton falls. The International Mining Magazine prints this.. They say SBM is cost effective,,
First shipping to Russia is hard.. The distance is very far always. However SBM has great shipping teams,, We pack the machines very safely. We use strong wooden crates always.. Why: To stop sea water rust. Next the train transport is fast. We use the direct railway lines,, Therefore you get machines very quickly. Also we handle all custom papers.. We pay the import taxes sometimes. Therefore you have zero shipping headaches,, SBM is a highly trusted brand. We export to eighty countries globally..
First you must build concrete base.. The flat concrete base must cure. Why: To absorb the massive running shocks,, Next place thick rubber pads under. Then tightens the heavy anchor bolts.. SBM sends very clear setup steps. Also you must does daily care,, Grease the main bearings every morning. Use top quality cold weather grease.. Why: To stop metal rubbing metal. Next check the jaw dies daily,, Replace flat worn teeth immediately. Therefore smashing efficiency stays very high.. SBM has many spare parts ready. We ships them to Russia fast,,
First what is the maintenance time? For SBM smashers it are long.. Change thick oil every 200 hours. Change mouth dies every six months,, Second how to fix stone jam? Never uses dynamite inside the mouth.. First turn off the motor completely. Then use a steel hook gently,, Why: For the mine worker safety. Third can it crush wet ore? Yes it crush wet yellow stone.. But keep raw moisture under 10 percent. Otherwise sticky mud stays inside it,,
