Liming Heavy Industry Minerals, the world’s leading rock and mineral processing group, has installed over 10 000 jaw crushers s ince the 1987s. Today the Liming single tooth jaw crusher i s indisputably the world’s favourite jaw crusher. Where cost-efficient primary reduction of hard, abrasive materials is concerned, single tooth Series crushers represent the highest technical and manufacturing knowledge.
All Single tooth jaw crushers are based on a revolutionary modular, non-welded frame construction. This design offers owners the highest possible fatigue strength, excellent reliability and numerous mounting possibilities. This, combined with high-quality cast steel components a n d p r emi um s p h e r i c a l r o l l e r b e a r i n g s , me a n s exceptionally high crusher availability, cost-efficient crushing and low cost per ton.
Indonesia contains some of the world’s richest mineral deposits and the fast-growing mining sector contributes 11.2 percent to the country’s gross domestic product. The Indonesian energy and minerals ministry has been drafting a rule that would by 2014 require miners to carry out minimum processing on minerals before export.
Indonesia requires miners to process coal and minerals into higher-value products before exporting them, as Southeast Asia’s largest economy seeks to boost revenue from the mining sector.
Indonesia imported many mining machines from Liming Heavy Industry in China, especially the single tooth jaw crusher. The single tooth jaw crusher is widely applied in Indonesia mineral processing, in gold explored, in chemical industry, in cement industry. The single tooth jaw crusher
There are now 2 ranges of models in the Single tooth range. The first is the well-known traditional jaw crusher range that is designed for stationary as well as mobile applications (PEW200×1300, PEW250x1000, PEW250x1200, PEW1100). The second range is designed specifically to meet the needs of small to medium size mobile crushing (PEW250x1200, PEW1100). All Single tooth crushers are designed
to crush very hard rock. Whatever your crushing needs – from hard and abrasive rock to various recycling materials – you’ll find the optimum solution with the Liming Single tooth jaw crushers. Take a closer look at the world’s favourite jaw crusher.
World-class craftsmanship and materials Single tooth crushers are premium class crushers due to their design as well as to the materials that are used to produce them. Attention has been paid to even the smallest details, so as to ensure the highest possible functionality and reliability, without any compromises. Those who have owned and operated Single tooth jaw crushers know
that not all jaw crushers are the same! Modular, non-welded construction A uniquely modular, non-welded frame construction is a state-of-the-art design with two hot-rolled steel side
plates joined to high-quality cast steel frames through robust, precision machined bosses secured with bolts. The absence of stress inducers such as weld seams ensures excellent durability against shock loads. Durable pitman assembly The pitman is made of high-quality cast steel and is propelled by two massive cast steel or iron flywheels. A very large eccentric shaft forging and four large spherical roller bearings that are all of the same size ensure the greatest reliability even under the most severe crushing conditions. The grease-lubricated bearings are kept free from contamination by means of well-proven labyrinth seals. Single piece cast steel frame bearing housings The single piece cast steel frame bearing housings ensure a perfect fit to the crusher frame. They also prevent unnecessary loads to the frame bearings that are common with 2-piece frame bearing housings.

will eventually need some care. Due to the use of cast steel components, the crusher can be economically. reconditioned or rebuilt after many years of operation. Such repairs are uneconomical or impossible to carry out with crushers of alternative designs
The right cavity design Single tooth jaw crushers are literally designed “from the inside out” because the cavity is the heart and only purpose of the jaw crusher. That is why over the years great attention has been paid to the feed opening dimensions as well as to the cavity height. The right feed opening width to depth ratio ensures minimum blockage and eliminates unnecessary height from the crusher. Aggressive kinematics and high power In addition to the right cavity dimensions, the right kinematics must be applied. That is why Single tooth jaw crushers have a large eccentric throw coupled with a steep toggle plate angle that magnifies the effective stroke at the crusher discharge. The large stroke, combined with the right speed, flywheel inertia and high available crusher power result in truly high crusher performance. Operation at small settings as well as the
method of setting measurement results in finer products in comparison to other crushers.
The right jaws for a given application Many types of jaws have been developed over the years
in order to optimize the performance of Liming Single tooth crushers in a very wide range of applications, including conventional quarries, mines, gravel pits, and recycling of demolition material and asphalt. The tooth profiles as well as the thickness of the jaws are optimized
and combined with the right manganese steel alloys to maximize throughput and minimize operating costs. Liming Heavy Industry Minerals also actively develops custom jaws for special applications. Special cheek plates are also available
Low installation and operating costs In addition to bringing you high performance, Single tooth crushers are also designed to bring your total crushing costs down. Each unique feature of the Single tooth brings specific benefits that have a direct impact on the bottom line – which means that you will be more profitable. Those who have owned and operated Single tooth jaw crushers know that not all jaw crushers are the same! Fast and safe setting adjustment systems All Single tooth crushers are equipped with a proven, rugged and fast wedge setting adjustment system. The wedge setting adjustment is simpler, much safer and faster than outdated shim adjustment systems. The crusher’s setting can be manually adjusted with tools that are supplied with the crusher in a matter of minutes, without having to handle dirty and bulky shims. Alternatively, the crusher’s setting can be changed in seconds, from a remote location, even while the crusher is idling! The system is also especially effective at clearing the crusher’s cavity should it stall under load due to interruptions in the supply of electric power. Tired of repairing your jaw crusher’s
foundation? Rubber dampers and stoppers effectively decrease crushing loads to the foundation by absorbing peak shock loads and allowing the crusher to move vertically and longitudinally. This unique and innovative system eliminates the need for anchor bolts, and is a much more desirable solution as all anchor bolts eventually damage jaw crusher foundations. The most durable bearings available All Single tooth jaw crushers incorporate larger and sturdier ec cent r i c sha f t bea r ings than other c rusher s of comparable size. Their higher load bearing capacity and effective labyrinth seals result in considerably longer bearing lifetimes.
