Through finite element analysis, lippmann engineers have been able to provide jaw crushers with maximum strength at all stress points; promoting trouble-free operation.
A jaw crusher is a compression type crusher, comprised of a fixed jaw and moving jaw positioned in a (v).The movable jaw compresses material against the fixed jaw, crushing the material to the desired size.The material exits the jaw through the bottom of the crusher otherwise known as the discharge opening.Changing the discharge opening controls the product size made by the crusher.Jaw crushers are mainly used at the primary stage of material reduction in several applications, including rock quarries, sand and gravel, mining, construction and demolition recycling, construction aggregates, metallurgy, and chemical industries.A jaw crushers flywheel, toggle plates, pitman, eccentric shaft, and driving motor generate the crushing action and provide the energy needed to break the material.there are some different styles of jaw crushers, the most common being the overhead eccentric jaw (shown above) or a double toggle jaw.Depending on the application requirements, jaw crushers are available in stationary, wheeled portable, and track-mounted options.Jaw crushers are often designated by the size of the top opening where material enters.The openings tend to be either rectangular or square and are referenced in inches.For example, a 3244 or 3244 jaw crusher has a 32 by 44 opening.32 being the gap at the top between the jaw dies and 44 being the width between the side plates.For more information about jaw crushers, please contact telsmith.View telsmith jaw crushers.
Nowadays, people put more and more emphasis on energy saving and emission reduction in mining industry.High efficiency and environmental protection are two key points to achieve the ultimate goal of building an energy-saving society.Enterprises can enhance the market share of the crusher equipments in mining industry; however, from the perspective of current development trend, high efficient and energy-saving jaw crusher will definitely be the future direction on research and development of mining machinery.
The wearing parts of jaw crusher are mainly the movable jaw plate, fixed jaw plate,.The special processing techniques ensure that our jaw plate has leading.
In order to further improve the production efficiency, reduce the operations costs, produce ideal fine powder, hongxing machinery exclusively design the cone crusher.It has longer working life, and higher output rather than jaw crusher.Based on decade's cone crusher manufacturing experience, hongxing experts designed hpc and hcs900 series cone crushers.With hydraulic driven, these cone crushers show outstanding reduction performance in secondary crushing, fine crushing, super fine crushing of limestone or taconite, ballast production or artificial sand, and small mobile crushing plants.
Rock is fed into a large opening at the top of the cone crusher where it is squeezed between the mantle and the cone.As the size of the rock decreases, pieces fall into lower levels of the crusher where they continue to be worn and broken down further.Once small enough, the fragments of rock exit through a narrow opening at the base of the machine.Cone crushers manipulate rock between a fixed cone and the movable cone (the central shaft).The width of the exit opening is adjustable through ascending and descending the fixed cone which allows the rock to be crushed to a variety of sizes.This method is more advanced than the one used in jaw crushers.You can see how jaw crushers work by clicking here.
The most important parts involved are impacted plate and hammer which experience severe abrasion because of strong impact energy.So the first way to prolong the life of the two parts is to choose the right equipment with high-quality and wear-resisting parts.Although the material of the impact plate and hammers in different manufactures looks same apparently, it is way too different in design.The excellent design would greatly reduce the abrasion if complete analysis and upgrade implemented on mechanical property and space design.The second method is applying impact rock crusher into secondary reducing after the primary crushing of fixed jaw crusher.The development of the mining industry and construction are in full swing, which raises higher demands on various mine resources in many countries.For example, elongated and flaky particle in final products must be less than 10% in many fields, which demonstrates the crucial role of impact rock crusher.
In this way, the ore that can pass through the sieve wifout having to be crushed may get into the fixed jaw crusher.Therefore, the generation of dust is greatly increased, so in order to better control the source of the generated dust, it is necessary to promptly eliminate the failure of the sieve blockage and reduce the amount of dust generated as much as possible.
Different materials hardness influence selections on equipment accordingly.For example, the option of cone crusher plus sand maker is usually applied to processing supper-hard minerals such as pebble and granite due to its greater efficiency and performance; while fixed jaw crusher, impact rock crusher and sand maker are commonly teamed up to reduce some kind relatively soft rocks like dolomite and limestone.Selecting equipment based on the features of materials will lead to an ideal result.
Pe jaw crusher is suitable for the coarse crushing of iron ore, and its discharge port can be adjusted which makes the crushing specifications are diversified.
Fixed jaw crusher: noise reduction noise is also a factor affecting energy conservation and environmental protection.According to the environmental protection survey report of 2015, noise not only threatens the living environment of human beings all the time but also harmsthe physical and mental health of human beings.Therefore, the radical treatment of noise is urgent to be solved.The emergence of noise cancellation circuitinstalled on the fixed jaw crusherimmediately attracts more attention from miners,because it not only fundamentally solves thenoise problem, but also improvesthe reliabilityonenergy conservation and environmental protection.the noise cancellation circuit is very flexible and it can be set on different parts of a jaw crusher according to the noise degree.
