That is: the sand making process is that big stones are crushed coarsely by the jaw crusher, and sent to the impact crusher or the cone crusher for further crushing, and then the material is delivered to the sand making machine by the belt conveyor.
In terms of production capacity, compared with impact crusher, cone crusher has the advantages of low consumption, large output, and stable production, so it is often used in large-scale and high-output production lines.
It is of multilayer and high efficiency (three layers or four layers), so it is often used in the behind of jaw crusher or impact crusher.This equipment manufactured by hongxing machinery adopted eccentric shaft vibration exciter and partial block helps to adjust amplitude, so that this kind of screen is of long stream line, many specifications and clear screening for different specifications.So it is widely used in the industries of quarry, building material, traffic, energy, chemistry, etc.
First, as mentioned, the jaw crusher is used for coarse crushing and medium crushing, while the impact crusher is more often used as the fine crusher machine.Second, the jaw crusher works with simple pendulum and the complex pendulum by the fixed jaw and the movable jaw.As for the impact crusher, it works with rotating pendulum.Third, when mentioning the working mean, we always say that jaw crusher always works with regularly short interval while the impact crusher with no interval.Sometimes, impact crusher can be replaced with cone crusher.But jaw crusher plays a more irreplaceable part in crushing plants.
Avoid the abnormal phenomenon that bearing is hot or damaged, and impact crusher vibrates abnormally, workers should operate the machine according to the specification and inspect and maintain from time to time.
As the specialist mining machinery manufacturing company, henan hongxing mining machinery co., ltd, it has almost 30 years' development and dedicates itself to mining crushing equipment, grinding equipment and ore selecting equipment.Many years, with the technology of perfection with more perfection and after-sales' service of perfection, hongxing machinery wins a great high benefit year by year.As the high quality of mining machinery equipment manufacturing company, we will create benefit for customers with first-rate technology, equipment and service to cooperate and create the national famous brand.As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing station.We also supply individual impact crusher and vibrating screen as well as spare parts of them.
The whole pcl certical impact crusher including feed hopper, classifier, whirl pool cacity, impeller, main bearing assembly base, transmission device and motor etc.Operating pinciple is as follows: the materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of 60-75 meter/second.First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity's scaleboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changs its direction and goes down, forms continual material layers with the materials shot from the impeller.Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed matetials will be excluded through the bottom discharginghole.This can from a closed circulation through the circular classifier system; in general, materials can be crushed into 20 mesh through thrice circulation.Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
The impact crusher is mainly composed of hammerhead, main shaft, impact plate, rotor, frame and grate bar.Several rows of hanging hammers are arranged on the main shaft of the impact crusher.
While many other types of crushing equipment use pressure to break the hard materials, the pf impact crusher uses an impact to break rocks and other materials.A machine of this caliber will need to be regularly maintained and inspected for the safety of employees using it.This app for pf impact crusher machine inspection should be used by an inspector when maintaining this piece of crushing equipment.
Combination of high speed & normal speed vertical shaft impact crusher.The stone material is fed into the vertical shaft crusher with normal (low) speed (v=5070m/s) by the feeder bin and the belt conveyor.After crushing, it enters the screening machine.The stone material with more than 5mm is returned to the transfer bin.5- 2.5mm of sand enters the finished sand silo, and another part of the stone is sent to the high-speed (v>75m/s) vertical shaft.The re-broken stone is mixed with the stone less than 2.5mm and then enters the finished warehouse.
The plate hammer and rotor of the impact crusher are rigidly connected.The inertia of the whole rotor is used to impact the material (free crushing, impact crushing, milling crushing), so that materials can not only be crushed but also obtain a larger speed and kinetic energy.The plate hammer is used to smash the input material from the bottom to up and throw it onto the upper impact plate.
However, impact crusher now there are still some problems.Which is more prominent is the board hammer wear faster (especially when crushing hard materials), and a wide particle size distribution (for some industrial sectors, the products do not want more fine particles or unnecessary).However, the current real obstacles impact crusher there are barriers to further promote the use, design and manufacturing sector to design and test the impact crusher is also a lack of systematic and complete understanding, in particular, specific design, take little of the crushing effect and equipment the relationship between structure and properties, the lack of theoretical basis, some places are also due to improper use.
