The post-primary crushing sector is largely divided into impact crushers for the processing of softer stone and cone crushers for the processing of harder more abrasive stone. The advantages of both machines are well known.
The impact crusher for example has a higher co-efficient of reduction produces crushed material with an optimal cubic shape for asphalts and concretes allows faster and simpler maintenance has a lower acquisition cost gives continuous production curves with no irregularities or breaks between sizes see Figure 1 permits bigger feed sizes and delivers higher production of small sizes. The cone crusher on the other hand has the advantage of fewer wear parts.
The vast majority of impact crushers have been conceived and designed to process relatively soft stone. Accordingly their construction materials and components are strong enough to cope with this kind of material but are generally insufficiently robust to crush harder more abrasive materials such as granite flint basalt and iron ore.
However what would happen if impact crushers could match cone crushers in terms of performance and wear costs In emerging markets such as Russia Africa east Asia and South America among others cone crushers are increasingly being replaced by impact crushers in granite and basalt quarries providing an improvement in the quality of crushed material and a reduction in the cost per tonne thereby increasing the competitiveness of some companies against their local rivals.
But how have impact crushers reached the wear parameters of cone crushers In the past the use of impact crushing for hard and abrasive stone was mostly limited to very small niche markets especially in countries such as Spain and Germany. It was in markets such as these that the impact crusher evolved and matured for 50 years to become the trusted product it is today.
Based on innovation and experience and an awareness of the advantages and disadvantages of impact crushers compared with cone crushers and the opportunities that this implies in overcoming the problem of wear a few manufacturers have worked on two key areas improving impact crusher efficiency and wear parts management and developing the technology of the materials from which the parts are made.
image3-ar-w620The development of ceramic chrome alloys to increase the durability and abrasion resistance of wear parts together with evolution in the management of these parts during use has resulted in a significant reduction in the cost per tonne of material produced.
The smaller the output size the more competitive impact crushers become because their percentage of finished product in the first pass is considerably higher than cone crushers. Combined with an upgrade to wear parts materials this can allow impact crushers to reach a lower wear-cost ratio per tonne than cone crushers see Table 1.
While it cannot be denied that the useful hours of impact crusher wear parts have not yet reached the useful hours of cone crusher wear parts in tertiary stage works they have been upgraded enough to be a better option than cone crushers in some situations allowing them to reach figures such as those shown in Table 1.
For secondary stage works impact crushers have equalled cone crushers overcoming all their disadvantages and matching their main advantage the wear-cost ratio.
The materials between the two jaw plates are crushed by extrusion bending and cracking. How gyratory crusher works. The crushing chamber of the gyratory crusher is composed of a moving cone and a fixed cone. When the crusher works the motor passes the power to the horizontal shaft and a pair of bevel gears through the large and small pulley.
What is the Difference Between a Jaw Crusher and an Impact Crusher
Cone crusher is mainly composed of fixed cone moving cone crushing wall transmission axis and frame etc. According to the principle of laminated crushing the materials are continuously crushed in the crushing chamber by squeezing into each other. The impact crusher is mainly composed of rotor plate hammer impact plate and lining plate etc.
Difference Between Jaw Crusher Cone Crusher and Impact Crusher
spring cone crusher Cone crusher is widely applied in cement making industry building sand making metallurgical industry etc. The cone crusher from Heavy IndustryShangHai is suitable for both metallic minerals and non-metallic minerals such as iron ore nonferrous metal ore granite limestone quartzite sandstone pebble etc.
Jaw crushers are typically used as primary crushers or the first step in the process of reducing rock. They typically crush using compression. The rock is dropped between two rigid pieces of metal one of which then move inwards towards the rock and the rock is crushed because it has a lower breaking point than the opposing metal piece.jaw stone crusher
Jaw crusher movement is obtained by using a pivot point located at one end of the swing jaw and an eccentric motion located at the opposite end.
This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness mid hardness and soft rocks and ores such as slags construction materials marble etc. The pressure resistance strength is under 320Mpa suitable for primary crush.Jaw Crusher can be used in mining metallurgical industry construction road and railway building conversancy chemistry etc.
When select the coarse crushing equipment in the crushing design should consider the ore characterand the finished products size requirements benefication plant scaleetc. We suggest that when crush the hard stones and long shape of stonesonly need two ore three sets of jaw crushers to meet the requirements and one cone crusher can replace so you should select the cone crusher firstly. Specially for the clinoform terrain this design is more favorable. When crush the wet and the sticky ores or in the medium sizedsmall-sized benefication plant jaw crusher is suitable.
difference between impact jaw cone crushers. Jaw and cone crushers There are various types of rock crushers used in the aggregate industry including impact and roll crushers with xuzhenybiaoti difference between hydraulic cone crusher. is a crusher .
difference between impact jaw cone crushers. C6X Series Jaw Crusher. product description ptimized performance easy maintenance long life and a low cost per ton. These crushers feature a deep symmetrical crushing chamber easy settings adjustment a large feed opening for its size and an ideal nip angle that offers smooth material flow .
SummaryAs we all know in the stone production line the broken processing stone is generally completed by a combination of rough and fine breaking. In the process of
In fact the impact crusher and the cone crusher are secondary crushing. The difference between the two is the appearance and the working principle.
1. The principle of breaking is different.The impact crusher adopts the principle of impact crushing. After the material enters from the feed inlet it is repeatedly crushed and crushed between the hammer and the counterattack plate until it is formed after molding. The cone crusher is laminated and crushed.Constantly moving toward the broken wall squeezing the material sandwiched between them to pulverize.
