Stone Crusher Overview:
project report for stone crusher
The stone crusher means exhaust compound particle size of greater than 3 mm in total content of high capacity more than 50% of the grinding machinery. Invented by British Hengan. Coarse crushing operations are often divided into feeding and nesting size size broken, broken, and crushing. The gravel equipment used jaw crusher, impact crusher, impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, cone crusher, roll crusher machines, double roll crusher, Combo crusher, crusher several molding.
Project Report for Stone Crusher:
As show the project report, impact stone crusher will be an example to show the usage, features, working principle and maintenance. The following is the project report for stone crusher:
Application of Stone Crusher:
Crusher appeared later, but the development of fast. It is actually a new and efficient crusher developed on the basis of the hammer crusher, impact crusher for crushing limestone, asbestos ore, coal, quartz sand, calcium carbide, dolomite, pyrite and other materials . Can be used to rough broken, broken, broken bits can also be used. At present, it has been industrial sectors such as cement, building materials, coal and stone industry as well as beneficiation are widely used in a variety of ores, crushing operations, ore coarse crushing equipment used.
Features of Stone Crusher:
Impact Crusher has been growing so rapidly, mainly because it has a need for superior characteristics:
1, Broken than great. General crusher crushing ratio does not exceed 10, and Impact Crusher crushing than is generally 30-40, up to 150. Therefore, the current popular three-stage crushing process, if the use of impact crusher, it would only take a while or both ends can be completed, which greatly simplifies the production process, saving investment costs.
2, The crushing high efficiency and low energy consumption. Because of the the general ore impact strength is much smaller than the compressive strength, the same time, due to the ore by blow board the high-speed and after several attacks, the ore along the jointed interface and organizations vulnerable first strike crack class crusher crusher, high efficiency, and low power consumption.
Uniform particle size, the less over crushed phenomenon. Subject to a greater degree of crushing in the crushing process, the lump ores, but the smaller particles of the ore, not to be broken under certain conditions, and uniform particle size of the crushed product, less over crushed phenomenon.
3, Can selectively broken. Impact crushing process, useful minerals and gangue first rupture along the joint plane, in order to facilitate useful minerals monomer separation, especially For the coarse crushing disseminated useful minerals, this point is more significant.
4, Adaptability. This crusher crushing brittle, less fibrous and medium hard ore, particularly suitable for limestone and other brittle ore crushing, cement and stone industries Crusher still very appropriate.
5, Equipment, small size, light weight, simple structure and easy maintenance.
Given all the advantages of impact crusher, countries are widely adopted, and vigorously develop. However, in crushing hard ore larger impact crusher board hammer (pads) and counter plate wear, in addition, the Crusher is a high-speed rotation by the shock to broken ore machine parts processing accuracy requirements and static balance and dynamic balance, in order to extend the service life.
Working Principle:
Ore into the crusher, received the impact of the high-speed rotary blow plate, ore along the bedding plane, joint planes selective fragmentation. The ore after impact, enormous energy, and high speed along the tangent direction of the board of the blow thrown to the first-class counter plate after the impact of the counter plate, the ore again received crushed, then from the first a counterattack plate block of material returned, they suffered against board re-impact, resulting in the "interlocking" type of ore Crusher crushing effect. When the ore journeys in between the pads and the counter plate, the addition to the fight against the impact plate and counter plate, there ore between several colliding role. This process repeated until the crushed material particle size is smaller than the gap between the pads and the counter plate, and discharged from the lower part of the impact crusher.
Usage and Maintenance:
In normal use, the operator according to the hammer plate wear and the crushed product size to adjust the radial gap between the impingement plate and the grinding plate and the hammer plate. With the wear plate hammer crusher product size will gradually thicken. At present, our company mainly manufacturing plate hammer and the impact of high manganese steel plate. Impact crusher bearing installed in strict accordance with the method prescribed by the manufacturer of the production of bearings, check and adjust the bearing clearance and lubrication device and the timely replacement of seals, bearings to ensure the normal work.
