pe series jaw crushers are widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. the unique advantages of jaw crusher are:
1, the crushing chamber is deep and no dead zone, which improves the feeding capacity and output.
2, its crushing ratio is big, the product size is uniform, the noise is low, the dust is few.
3, the adjusting device of the gasket type discharge port is reliable and convenient, and the adjustment range is large, which increases the flexibility of the equipment.
4, the lubrication system is safe and reliable, the components are convenient to replace, and the maintenance workload is small.
5, simple structure, reliable operation and low operating cost;
6, equipment energy saving: single machine energy saving 15% ~ 30%, system energy saving more than doubled;
7. the adjustment range of the discharge port is large enough to meet the needs of different users.

with the development of the economy, the country continues to promote the construction of various basic designs. the demand for aggregates has increased. due to the growing shortage of natural sand resources, machine-made sand has become the main building material in infrastructure construction. the gravel production line is a special production line equipment for the production of sand and stone for construction.
the production line can be equipped with jaw crusher, vibrating screen, sand making machine, etc. according to the production needs. it can put rock, gravel, river pebble and other materials. it is made into various particle sizes that meet the requirements of construction sand. the sand made from sand and gravel production line has uniform grain size and high compressive strength. it is far more suitable than the sand produced by natural sand and ordinary hammer sander. building quality.
the sand production line has the characteristics of reliable performance, reasonable design, convenient operation and high work efficiency. in the sand production line, the jaw crusher is used for primary crushing of large stones. there are many options for the jaw crusher model, which can accept different feed sizes. the stone material is uniformly sent to the jaw crusher by the vibrating feeder for coarse breaking.
the material after the coarse crushing is transported by the belt conveyor to the fine crushing jaw crusher for further crushing, and the finely crushed material is sent to the vibrating screen for screening. the material that meets the particle size requirements of the finished product is sent to the sand washing machine for cleaning.
the material that does not meet the particle size requirements of the finished product is returned from the vibrating screen to the sand making machine for re-machining to form a closed circuit for multiple cycles. finished product granularity can be combined and graded according to user needs.
jaw crusher is divided into large, medium and small according to the width of the feed port. the feed port width is greater than 600mm for large machines, and the feed port width is 300-600mm for medium-sized machines. the feed port width is smaller than 300mm is a small machine.
the jaw crusher has a simple structure, is easy to manufacture, reliable in operation, and convenient to use and maintain. the fineness of the jaw crusher can be varied from 10mm to 105mm, and it can be adjusted according to customers' needs. jaw crusher prices vary according to model and production capacity.
at present, there are many crusher manufacturers in the mining industry. if you want to invest in crusher equipment, you must first understand the manufacturer and customize a reasonable crushing production line according to your actual production needs.
choosing the right jaw profile for your primary crushing application
it’s important to choose the right jaw profile for your application. an incorrect jaw profile can lead to increased downtime through excess wear, lower efficiency and capacity, or even breakage of the crusher. however, choosing the most appropriate jaw profile for the primary crushing application can be tricky, since each application has several different variables such as feeding, opening and feed material properties. here are some tips for how to choose the correct jaw profile for your application to get the most out of your crushing operation and achieve optimal production.
to achieve optimal production, it is important that the feed material fits into the chamber. the maximum feed size should be 80% of the nominal value of the feed opening. since thicker liners take up more space, this also has an impact on the maximum size of the feed material that can be fed to the jaw crusher. it’s also important to consider the feed arrangement. this means that the feed divides evenly to the jaw, and that the jaw should be full so that the crusher operates optimally.
feed material affects the choice of your jaw profile
the type of feed material determines what type of jaw profile you should choose for your crushing application. whether you have a soft or hard rock application or you are working in recycling, it’s important to choose a jaw profile that can crush the feed material efficiently. it’s also crucial to take account of issues such as the quantity of fines in the feed material, excessive humidity and lamellar material. considering all these factors helps achieve better capacity, maintain an optimal chamber shape, and avoid backing or breaking the machine, leading to unwanted downtime.
here are a few examples of the numerous applications and cases of what to consider when choosing the wear profile based on the feed material. the rule of thumb is to consider the crushability of the feed material and its characteristics.
for example, if you are crushing gravel, the crushability may be easy. for this purpose, we recommend the super grip or standard jaw to achieve the optimal result. for hard and abrasive feed material, it is ideal to choose a jaw profile that has design factors that withstand heavy wear. for example, a jaw profile with more wear-resistant manganese steel and a flat tooth profile are good options to consider when the feed material is very wearing.
to achieve the ideal outcome, the feed material should not contain fines. however, in some production cases, there may be no scalper available, or the scalping is inefficient, meaning the fine material ends up in the crushing chamber. for feed material with fines, a jaw profile with well-spaced teeth that let fines flow through is ideal. for example, coarse corrugated jaws are optimal, because the design allows for fine material to easily pass through the chamber. they are also optimal for feed that tends to break into slabs, reducing the amount of slabby material in the crusher discharge.
