What are the methods for adjusting the output of jaw crusher? First of all, we must ensure that the power supply voltage of the crusher production process is stable and the production has a good condition; the wiring position of the jaw crusher motor is reversed, which affects the work of the motor. The size of the discharge port of the jaw crusher is small, and the production output is reduced, and the discharge port is blocked. Therefore, it is necessary to increase the size of the discharge opening; the displacement of the jaw of the jaw crusher will also affect the equipment. Working condition and work efficiency, to ensure the position of the seesaw is suitable; after the use of the jaw crusher for a period of time, the jaw structure and the bearing wear increase the working gap, the bearing rotates relative to the outer ring, so that the output is reduced, and the seesaw can be checked frequently. And the wear condition of the bearing and replace it in time. When the output of the jaw crusher in Shanghai SBM Heavy Industry declines, it is necessary to find the key to the problem according to the possible failure, find the problem in time and solve the problem, and ensure that the equipment can operate efficiently.

What are the accessories that affect the production of crushers in Shanghai?
What are the accessories that affect the production of crushers in Shanghai? When it comes to the production efficiency of crushers, it is not difficult to think of the wearing parts of crushing equipment. It can also be said that it is accessories or parts. Shanghai SBM Heavy Industry Crusher manufacturers give customers a simple analysis. First, the high-speed transformation of the hammer causes a sharp impact between the material and the hammer and the screen and the tooth plate, which is called crushing of the material. In the process of severe impact, the hammer will gradually wear under the impact of the front of the material, and the impact effect and the crushing effect will be greatly reduced, resulting in a decrease in work efficiency. Secondly, the bearing is an important part for fixing and reducing the friction coefficient during the working process. Because the machine not only increases the energy consumption of the metal crusher but also easily damages the bearing when the machine is running at high speed, Shanghai SBM Heavy Industry adopts pre-lubricated bearings, which is The bearing has its own lubricant.

When the Raymond mill is aging, it is necessary to take appropriate remedial measures. If the problem is serious, the equipment needs to be replaced. In the actual production process, there are many ways to delay the aging phenomenon of the Raymond mill. Then, how do users carry out maintenance work on the equipment and delay the aging of the equipment?
First, choose the right lubricant, the oil should be moderate, the long-term lubrication of the equipment will not cause the equipment to wear seriously, and this is also an important cause of equipment aging. If the lubrication is not good, it will greatly increase the wear level of the equipment. Reduce equipment usage time. During the use of Raymond mill, the lubricating oil should be lubricated with the correct lubricating oil to avoid contamination of the lubricating oil. The amount of lubricating oil should be moderate. Do not add too much oil.
Second, do a good job of equipment maintenance, parts that are severely worn need to be replaced in time, in the use of Raymond mill, should carefully observe the use of various parts of the equipment, especially the use of wearing parts, in a timely manner Check the records and record the number of inspections for each component, and repair some of the worn parts in time and replace if necessary.
Third, preheating before starting in winter, lubrication in summer, cold weather in winter, low temperature, easy to freeze oil, so when using Raymond mill, you need to carry out preheating for a few minutes of empty operation to avoid equipment running. Failure, downtime, etc. The temperature in summer is high. Under high temperature operation, the temperature of the equipment is relatively high, which is easy to cause damage to parts. Therefore, the lubrication of the equipment must be done well to reduce the heat generated by friction.
1, material properties. It is related to the hardness, properties and composition of the material. Hard materials can easily cause wear of the fine jaw crusher, and some materials can cause corrosion and blockage of the fine jaw crusher.
- Structural design. Reasonable structural design can effectively reduce the wear of the fine jaw crusher and vice versa.
3, materials. The correct choice of the material of the fine jaw crusher will affect the loss of the equipment.
- Operational use. Even the finer and more wear-resistant materials of a fine jaw crusher will not last long if handled and used improperly.
Generally, the crystal grains are fine and uniform, and the carbides are spherical and uniformly distributed, which are favorable for improving the rolling fatigue life. After processing the bearing steel, the more retained austenite, the coarser the needle-shaped martensite, the lower the residual compressive stress and the strength of the carburized layer, and the greater the possibility of microcracking. Under the same undissolved carbide state, when the mass fraction of carbon in the martensite is about 0.4% to 0.5%, the strength and toughness of the material are better matched, and the contact fatigue life is high. For undissolved carbides, it tends to be small, small and uniform by appropriate heat treatment, avoiding the occurrence of coarse or banded carbides, and is advantageous for eliminating fatigue cracks. As the hardness increases within a certain range, the contact fatigue strength will increase. In addition, the hardness matching of the two contact rolling elements is also important.

Raymond mill is suitable for various mineral powder preparation, pulverized coal preparation, etc. It has a three-dimensional structure, small floor space, strong setness and excellent performance, and is well received by users. Then, after the Raymond mill is in operation, attention should be paid to the details that affect the long-term use of the Raymond mill. The following describes the problems that should be noted after the Raymond mill is shut down.
- It is forbidden to stop the lubrication and water cooling system before the main body of the Raymond mill and the main bearing temperature have not dropped to normal temperature.
- After the Raymond mill stops moving, the high-pressure floating device should be turned on immediately to prevent the bearing alloy and the hollow journal from being damaged due to the cooling shrinkage of the grinding body until the grinding body cools to normal temperature (ambient temperature).
- When using the auxiliary transmission device to rotate the grinding machine, turn the inlet valve of the exhaust fan of Raymond mill to 20%, and the hot air valve is fully closed.
- After the system main and auxiliary machines are stopped, the valves should be closed and the recorder switch should be closed.
5, the exhaust gas treatment system should be based on the Raymond mill after the shutdown, the rotary kiln system to stop the material to adjust the system pressure (such as the humidification tower valve, the size of the relay fan opening, etc.).
The above mainly introduces the five major precautions after the Raymond mill is stopped, mainly for some detailed operations. These operations can reduce the damage of the equipment and ensure its performance. Many users can easily ignore these details after shutting down, even Some people think that only the running link is important. This kind of thinking is not advisable. Whether it is before or after use, or in use, only pay attention to all aspects of detail to ensure the normal use of the mill and ensure the performance of the equipment.
The position of the casting in the mold during casting affects the quality of the precision casting, the dimensional accuracy, and the difficulty of the molding process.
The selection principle of the pouring position:
- The important processing surface of the precision casting or the main processing surface is facing down or on the side: when pouring, the gas, molten slag and the sand in the mold will float upward, which may cause pores and slag inclusions in the upper part of the casting. Defects such as blisters, and the possibility of defects in the lower part of the casting, the organization is denser.
a. The casting position of the machine bed should face the rail face down to ensure the quality of the important working face. The quality of the circumferential surface is relatively high. The vertical casting scheme is adopted to make the circumferential surface on the side to ensure uniform quality.
- The casting of the precision casting is directed downward or obliquely: due to the strong thermal radiation of the molten metal on the upper part of the casting, the top sand-shaped expansion arches are even cracked, causing sand, blisters, etc. in the large plane. defect. The large flat face down or the oblique casting method can avoid large-scale production casting defects.
- The thin wall of the precision casting is facing down, sideways or inclined: in order to prevent cold partitioning of the thin part of the casting and no defects, the thin wall with a larger area should be placed in the lower part of the casting or placed on the side wall or Tilt position.
- The thickness of the precision casting should be placed on the top or on the side of the parting surface. The main purpose is to facilitate the feeding of the riser in the thick part.
Stainless steel casting is to use a suitable investment material to make the investment mold. Repeat the coating of the refractory coating, refractory sand, hardening and drying on the investment mold, and then melt the internal investment material; then, the strength is sufficient by roasting. A shell type without residual investment material for casting molten metal to obtain a high-precision casting. The lost wax casting process is adopted, the investment material is paraffin and stearic acid, the wax mold making and shell making process adopts an automatic assembly line, and the coating uses water glass as a binder.
The precision casting has a high production efficiency and a small footprint. For the middle part, various high-pressure molding machine production lines and air-punching molding lines can be selected to meet the requirements of fast and high-precision molding production lines. Selection: high-efficiency core making methods such as cold core box, hot core box and shell core. Medium-sized large castings can be considered for the application of resin self-hardening sand molding and core making.
One of the more common problems encountered in the process of precision casting is that there are pores inside the product. For some parts with higher requirements, the pores inside are not allowed inside, so the silica sol is precision cast in processing. It is necessary to prevent stomata.
The choice of precision castings in terms of their methods and methods should be considered, mainly for the adaptability of the method, and whether advanced modeling or core-making technology can be used to improve work efficiency through equipment. For the casting of ferrous metals, it can be precision cast. Moreover, depending on the characteristics of the casting, it can be used to produce some thin-walled castings.
