1. Lithotriptor can be divided into medical lithotriptor and mining lithotriptor. The medical lithotriptor is mainly used for the crushing of stones, generally using resonance and other ways to crush stones, to avoid various risks brought by surgery< According to the action mode of crushing force, crushers can be roughly divided into two categories:
(1) crusher (2) grinding machine
2. According to the crushing mode and mechanical structure characteristics (action principle), crushers can be roughly divided into six categories
(1) jaw crusher (tiger mouth). The crushing action is that the movable jaw plate periodically presses the fixed jaw plate to crush the ore block in it
(2) cone crusher. The ore block is between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically to crush or break the ore block in it
(3) roller crusher. In the gap between two opposite rotating round rollers, the ore block is mainly subjected to continuous crushing, but it also has the function of grinding and stripping, and the toothed roller surface also has the function of splitting and crushing
(4) impact crusher. The ore block is broken by the impact of fast rotating moving parts. Belong to this category can be divided into: hammer crusher; Cage crusher; Impact crusher
(5) grinding machine. The ore is crushed by the impact and grinding of grinding medium (steel ball, steel bar, gravel or ore block) in the rotating cylinder
A. roller mill: grinding materials by rotating rollers< B. disc mill: the disc rotation of vertical axis or horizontal axis is used as crushing part
C. centrifugal mill. High speed rotating parts and medium are used to proce centrifugal force to complete crushing
D. vibration mill. High frequency vibration is proced by the rotating shaft, which makes the medium and material collide with each other to complete the crushing effect
all kinds of crushers have different specifications and different application ranges. Jaw crusher or rotary cone crusher are usually used for coarse crushing; The standard cone crusher is used for intermediate crushing; Short head cone crusher is used for fine crushing.

2. Ripple consensus algorithm
enables a group of nodes to reach consensus based on the list of special nodes. The initial special node list is like a club. To accept a new member, 51% of the members of the club must vote. Consensus follows 51% of the power of the core members, while outsiders have no influence. Since the club started "centralized," it will always be "centralized," and if it starts to corrupt, shareholders can do nothing
5. Pbft: practical Byzantine fault tolerance
pbft is a state machine replication algorithm, that is, the service is modeled as a state machine, and the state machine replicates in different nodes of the distributed system. Each of the state machine saves the state of the service and implements the operation of the service. The set of all copies is represented by the capital letter R, and each is represented by an integer from 0 to | R | - 1. For the convenience of description, let | R | = 3F + 1, where f is the maximum number of copies that may fail. Although there can be more than 3F + 1 copies, additional copies can not improve reliability except for performance degradation
the main features of pbft algorithm are as follows: the client sends a request to the master node to call the service operation; The master node sends the request to other copies through broadcast; All copies execute the request and send the result back to the client; The client needs to wait for F + 1 different replica nodes to send back the same result as the final result of the whole operation.

3. Calculation method
1. Calculate I = Dmax / Dmax by the ratio of the maximum particle size of the material before crushing and the maximum particle size of the proct after crushing, where Dmax is the maximum particle size of the material before crushing; dmax― http://www.ysxuankuang.com/cpzx.html - the maximum particle size of the material after crushing
2. The ratio of the effective width of the feeding port and the width of the discharging port of the crusher
I = 0.85b/b
where
b --- the width of the feeding port of the crusher; B --- Crusher & lt; Width of discharge port
0.85 -
ensure the effective width of the crusher gripping the material. The maximum width of discharge port is selected for coarse crusher; Take the minimum width of discharge port for middle crusher
3. Calculate with average particle size
I = DCP / DCP
where
DCP - average diameter of material before crushing; DCP - average diameter of crushed material. The crushing ratio obtained by this method can truly reflect the crushing degree of sand and stone equipment.

5. The required equipment are: (1) impact crusher (2) plate feeder (3) mobile feeder (4) buried scraper feeder (5) vibration screening machine (6) conveyor belt (7) ore washing machine (8) magnetic separator - Henkel machinery
6. There are many crushers for crushing big stones, such as hammer crusher, impact crusher, impact crusher, etc. How to choose, it depends on what kind of material you are crushing, what kind of stone, limestone, cobble, granite or other, different materials, different import and export materials, and the requirements of desktop proction all decide to find different types of crushers. It's better to find a manufacturer, tell your requirements in detail, and then let it recommend the suitable model. Coarse crushing and fine crushing are mainly distinguished according to the size of crushed materials.
7. When working, the rotation of the motor is driven by the eccentric sleeve through the belt pulley or linkage shaft, the transmission shaft of the cone crusher and the cone part of the cone crusher. Thus, the crushing wall of the crushing cone sometimes approaches and sometimes leaves the surface of the mortar wall fixed on the adjusting sleeve, so that the ore is constantly impacted, squeezed and bent in the crushing cavity to realize the crushing of the ore< Main features of cone crusher:
(1) hydraulic system, which is used to adjust the discharge day of the crusher, can effectively ensure the safe operation of the equipment. When there is a foreign matter in the crushing cavity, the hydraulic system can make the moving cone fall back automatically. When the foreign matter is discharged, the system can make the falling moving cone reset automatically. Maintain the original position of the ore outlet and continue to work
(2) crushing cavity type, which refers to the geometric space formed between the moving cone and the fixed cone. The shape of crushing cavity has a great influence on the performance of the whole machine. The cavity shape of crusher is the main technical index of crushing. The machine has four kinds of cavity designs from coarse crushing to fine crushing. It has six possible combinations, which means that it can best meet the special requirements of users
(3) reliable sealing: labyrinth sealing device is used to replace the water seal used in the past, so that st and impurities can not enter the body, so as to ensure the cleanness of lubricating oil, prolong the service life of sliding bearing and thrust ball bearing, and make the machine run reliably.
(4) convenient replacement: in the past, the replacement of crushing wall of crusher was very slow, The new structure of cone crusher can replace the crushing wall very quickly. Because the upper crushing wall is equipped with a clip, the crushing wall is fixed by jacking up with bolts. The lower crushing wall is fixed by hydraulic nuts. There is no need to add any filling material on the back of the upper and lower crushing walls, so the replacement speed reces the labor intensity of workers
(5) adjusting the opening: the machine adopts a high-pressure displacement sensor, and the position of the ore discharge opening is adjusted in the operation room. As long as a button is pressed, there will be a display on the console, and you can see the size of the ore outlet to be adjusted, which is very convenient and accurate. When the machine is working, the motor drives the large bevel gear at the bottom of the eccentric sleeve through the hydraulic coupling and small bevel gear, which makes the eccentric sleeve rotate, causing the cone to swing and break the material. The main shaft of the crusher is not moving, it only supports the spherical bush of the ster to bear the crushing force. Because the main shaft of the crusher does not move and the eccentric sleeve transmits the crushing force, the structure can bear large crushing force, and is very suitable for fine crushing and ultra-fine crushing, because the crushing force of ultra-fine crushing is very large. It is estimated that the particle size of the proct (for the ultra-fine crushing liner) can reach 50 ^ 80% within one 5m (depending on the properties of the material). The crusher is suitable for the third stage crushing or the fourth stage crushing in metal mine concentrator; It is suitable for building materials, nonmetal mines and civil engineering. Especially in areas where the supply of natural sand for civil engineering is insufficient.

9. Different crushers discharge materials in different ways. Most of them discharge materials by natural gravity or extrusion, and the filtering methods adopted at the discharge port are also different. For those with grate bars and sieve plates, there are also those without filtering devices according to the different working modes of crushers. The materials filtered out by the sieve plate are relatively uniform, and the size of the discharged materials depends on the size of the sieve hole. However, when there are too many materials in the crushing chamber, it is easy to block the machine and the discharge port. However, the size uniformity of discharged materials is not as good as that of sieve plate. For those without filtering device, the material crushing must be sufficient to ensure that the discharged material can meet the requirements (such as impact breaking and cone breaking). In addition, it is not ruled out that the protection device such as over iron can be started to make the temporary passing material particles too large.
