Jaw crusher

1. Eth is Ethereum and Zec is zero

2. 1. Strictly control the feeding size to avoid jamming and blockage.

there is a formula for the design size of feeding port of jaw crusher: feeding port size = (1.1 ~ 1.25) * maximum particle size of raw material

many proction personnel do not understand it, and always take the measured feed port size as the maximum feed size. Therefore, the raw materials with large particle size exceeding the requirements become the culprit of blocking the cavity slot. Although it is not blocked repeatedly, the equipment will not operate normally for a long time every time. Therefore, strict control of raw material particle size is one of the most important preconditions to ensure the normal operation of jaw crusher

2. Strictly control the feeding amount to prevent the blockage caused by excessive feeding

many enterprises transform the silo blindly in order to improve the proction capacity, which often leads to excessive feeding

because the working principle of jaw crusher is half rhythm, if excessive materials are put in, the materials will not be broken in time, and the broken materials can not be eliminated in time, resulting in material jam. Therefore, the capacity of jaw crusher will be affected by material breaking and excessive feeding

3. Rhythm feeding, control feeding, ensure the normal operation of jaw crusher

at present, the crushing section of mineral processing enterprises is mostly fed by end chute, 2 / 3 of the whole feeder is even exposed outside the bin. Due to the remote feeding port, the feeder is completely changed into a vibrating chute, which not only has poor feeding speed, but also has serious wear. The best feeding position of the feeder should be in the range of 1 / 3 of the top of the equipment, but vertical feeding is strictly prohibited to prevent the equipment from losing its vibration ability or affecting the conveying effect
4. Adjust the angle of the feeder, make full use of the screening function of the feeder to achieve pre screening

vibrating feeder often has grate bar, which has some screening functions. However, in practical application, e to the amplitude, feeding angle and other reasons, it is easy to block the grate bar in the screening process, which makes it lose its original efficiency. In the face of this situation, many enterprises block the grate bar with steel plate and turn it into a plate feeder

in fact, the grate bar of vibrating feeder can play an extremely obvious role when it is properly adjusted. It is the best way to improve the overall flow rate by adjusting the amplitude and the angle of the feeder and fully releasing the screening function of the feeder< The processing capacity of jaw crusher is determined by adjusting the discharge port and bite angle of jaw crusher to increase the processing capacity of the equipment to the maximum. The jaw crusher is often used as coarse crushing equipment, the size of its discharge port should be based on the optimal feed size of two-stage crushing, and the size of discharge port should not be arbitrarily increased or reced

the bite angle (the angle between the movable jaw plate and the fixed jaw plate) needs to be adjusted strictly, generally in the range of 17 ~ 26 degrees (subject to the actual situation).

3. Jaw crusher or choose casting structure, the quality is more reliable, more cost-effective. Shandong Ruilong's casting jaw crusher procts cover many provinces and regions in China, and the export volume is also quite large. I suggest you go to the manufacturer and compare the manufacturer with the proct.

It has been 150 years since the first jawbone machine appeared in 1858. The jawbone machine is widely used in many fields because of its simple structure, reliable performance, easy operation, convenient maintenance and strong adaptability. Jinjiawu gold ore dressing plant of Jiangxi Tianbao mining company was built in 2005. The designed capacity is 1000 tons per day. The crushing system adopts three stages and one closed circuit process. C80 jaw crusher is used for coarse crushing and pex-250 proced by a famous enterprise in Shanghai is used for medium crushing × Gp100 cone crusher is used for fine crushing. Both coarse and fine crushing are proced by Nordberg C series and GP series

there are many kinds of c-series jawbone machines, including 12 kinds, with specifications ranging from C63 to c3055; Equipped with motor from 45KW to 400KW; The feed size ranges from 350mm to 1200mm; The weight of the equipment also ranges from 6 tons to 23 tons. C series is suitable for coarse crushing operation. As shown in Figure 1

2.2 after assembling

the bolts of the bearing seat of the frame are tightened, there are plates to weld the bolts together in pairs. Matching marks have been made on the frame, connecting screw, middle plate and side plate, which will not cause reverse installation. Specific value of torque is provided for each pre tightening nut

if it is a large machine, when it needs to adjust the discharge port by hydraulic pressure, the specific values of electrical circuit, selection of hydraulic oil and pressure of accumulator are provided

similarly, when assembling the flywheel, each head key has a matching mark with a flywheel and an eccentric shaft, there is no clearance between the flywheel and the eccentric shaft and the bearing labyrinth of the frame, the flywheel is cast with the unique number of the equipment, and the three bolts on the flywheel cover are directly welded together with a flat plate. If there is any looseness ring use, the welded flat plate will break, The operator can judge the shutdown based on this, which will not cause accidents

2.3.1 the adjustment of discharge port is completed by moving two wedges (close or far away), as shown in Figure 2. This movement will effectively change the thickness "s" of the wedge pair, thus increasing or recing the discharge port of the crusher. The device is composed of wedge block (1), nut (2) and locking pipe (3). It is convenient and quick to adjust the discharge port, unlike the domestic equipment which can be adjusted by adding a plug board

when changing the size of the discharge port, loosen the tension bar and the bottom spring nut, as shown in Figure 3, and then turn the nut clockwise or counterclockwise to increase or decrease the discharge port of the crusher. The net effect of a complete rotation of a nut on the discharge of crusher is 2.3mm, taking C80 as an example. Both the discharge port and nut of crusher are provided with nameplate to inform the net effect of each rotation. Turn the two nuts in the same relative direction for a complete circle, the change value of the crusher discharge port will be twice of the value shown

example: change the discharge port of C80 crusher to 10 mm, and the amount of nut rotation is as follows: 10 (mm) ÷ 2.3 (mm / turn) = 4.35 ≈ 4 turns (two turns for each nut). Like the domestic jawbone machine, C80 also needs to loosen or tighten the spring when adjusting the discharge port. The difference is that the latter has a nameplate mark at the spring, and specifies the working length of the spring. For example, C80 indicates that the length of the tension spring is 310mm when it works normally, and a protective plate is set at the tail of the spring to prevent the nut from loosening and the spring from popping out ring the operation of the machine

2.3.2 rib plate

the rib plate thickness of domestic jawbone can reach 55mm, and one rib plate is often more than 100kg; The thickness of C80 rib is only 16mm, the area is smaller and the width is similar. It's much more convenient to replace. From the operation point of view, once the domestic machine enters the ironware, the rib plate will break, while for the C series machine, the rib plate will break after elastic bending. In practice, on April 5 and May 4, 2006, a 16 pound hammer entered the coarse ore bin twice, but it was not found. When it entered C80, the rib plate did not break. Instead, it tilted and bent at an angle, allowing the heavy hammer to break normally after the hammer was discharged. At that time, it was found that the rib plate was in good condition and the bearing was not damaged

2.4 appearance

C series crusher and domestic jaw crusher of the same specification www.sbmepj.com In comparison, the weight is much lighter, the external size is small, and there are not too many anchor bolts. Although the movable jaw is a casting part, its surface is smooth and spray paint is exquisite. The flywheel of the engine block has a unique number, which is consistent with the instruction manual. The whole machine is refined

Conclusion from the design, configuration, material, assembly, operation, maintenance and other aspects of C series jawbone machine, it is safe, convenient, efficient and perfect, which is unmatched by domestic machine. Foreign manufacturers of jawbone machine, such as Nordberg, telsmith, kuc Ken, etc; Svedala, Sweden; Krupp, KHD, Germany; Kobe Steel, etc. They have a certain advantage in the market e to their excellent manufacturing, high reliability, good performance and advanced automatic control technology. Only when we see the gap can we know the direction of our efforts. In the future, domestic equipment can be developed in the following aspects:

(1) humanized design. Fully considering the safety of operators, maintainers and the equipment itself, the design of C80's feed observation shield, discharge belt protector and spring guard will rece the possibility of personal and equipment accidents, which will rece intangible losses to users. It is very popular with users

(2) mechatronics and intelligence. Since the 1980s, people pay more attention to high efficiency and energy saving, and pay more attention to the synchronous development of mechatronics and electronic control technology. The combination of machinery and electronics, mechanical technology and control technology, information technology, sensor technology make the development of Mechatronics crushing equipment and a new generation of intelligent crushing equipment become a reality

(3) finish machining and high quality. Compared with well-known foreign manufacturers, there are obvious gaps in processing quality and material quality; Change the big and stupid image, replace the small and refined shape, start from each screw

9. The output of jaw crusher is from 0.5 tons to 500 tons. Jaw crusher is mainly used as the first crusher to crush large pieces of raw materials.

10. Motor is also a motor, which includes motor and generator. I think what you mean by motor is motor, which means motor. Motor is used in all places that need rotating power, such as water pump, fan, oil pump, conveyor belt, etc...... The power source of all systems.... It's called hydraulic motor. There are few supplementary answers. The supplementary answers are not clear. Hydraulic motor is not what our electrical major is doing here. I'm sorry that we can't help. Motor is the old name. Now it's called motor. The jaw crusher, cone crusher, counter roll crusher, impact crusher, belt conveyor, barrel mill, Raymond machine and vertical mill are all driven by electric motor
it has the advantages of easy installation, small size, no smoking and no inflammables. The disadvantage of the motor is that the speed is too high, so it must be equipped with a recer to output larger torque. Hydraulic motor can realize stepless speed regulation without recer. The motor must be equipped with frequency converter if it wants to speed without pole. I said where the motor is used; Hydraulic motor is used in winch drive of wheel crane; There are some large radial drilling machine feed mechanism; Drill pipe drive of drilling machine, etc. Its transmission is not accurate. It's OK to be a booster for large-scale instruments, but it's troublesome to have pump station support. Motor: a rotating machine that works on the principle of electromagnetic inction.
Motor: the general name of engine (prime mover), also known as engine.
