Maintenance of the Raymond Mill? How much does Raymond mill cost?

Maintenance of the mill.

1. During the use of the mill, the fixed person should be responsible for taking care of it, and the operator must have a certain technical level, and the relevant personnel must be trained before the installation of the mill. Make them understand the principle and performance of grinding and be familiar with the operating procedures.

2. In order to make the mill work normally, the "maintenance and safe operation system" of the equipment should be formulated to ensure the normal and safe operation of the mill, and at the same time, there should be necessary maintenance tools, grease and accessories.

3. After the mill is used for a period of time, it should be overhauled, and at the same time, the vulnerable price such as the grinding roller, the grinding ring, the shovel blade should be repaired and replaced, and the connecting bolts and nuts should be carefully checked before and after the grinding roller device is used, whether there is looseness, and whether the lubricating grease is sufficient.

4. If the grinding roller device needs to be replaced again if the grinding roller is used for more than 500 hours, the rolling bearings in the roller sleeve must be cleaned, the wearing parts should be replaced, and the refueling tool can be used with a manual refueling pump or grease gun.

Raymond Mill. Routine maintenance is important, and the following needs to be done.

1. Strictly control the moisture of the grinding material.

When the water content of the material is large, it is easy to produce the phenomenon of paste grinding, and the fine powder in the grinding adheres to the grinding body and the lining plate, which reduces the grinding efficiency, and in serious cases, it will block the grate hole of the compartment plate and cause poor ventilation of the mill, the material is difficult to pass, the output drops sharply, and the quality also causes large fluctuations.

According to the practical experience of production, the moisture content of various materials can be controlled within the following range: limestone 1%, clay 2, iron powder 8, mixed material 2, gypsum 8, clinker, coal 4, comprehensive moisture control within the range.

2. The manufacturing accuracy of the grinding ring.

Because when the mill is working, the grinding ring that rotates with the spindle is one of the main wearing parts, so the manufacturing accuracy of the grinding ring directly affects the service life of the grinding ring, and the radial runout of the grinding ring and the heat treatment deformation of the grinding ring should be controlled, and the radial runout and inner diameter deformation will aggravate the impact and vibration of the grinding roller, increase the additional load, thereby shortening the service life of the grinding roller and the grinding ring.

3.The positive pressure of the grinding roll and the gap between the grinding roll and the grinding ring.

The positive pressure of the grinding roller is adjusted by the external spring, and the appropriate spring pressure must be adjusted according to the hardness, particle size, moisture, feed granularity and fineness of the desired finished product of the material, and the gap between the grinding roller and the grinding ring is an important parameter that directly affects the output and fine powder content. Generally speaking, the material processed by the user is relatively fixed, and the gap between the grinding roller and the grinding ring should be adjusted according to the size of the feed particle size. In addition, after the mill works for a certain time, due to the wear of the grinding roller and grinding ring, the gap between them will gradually increase, and it should be adjusted in time.

4.Lubrication of the main engine and classifier.

The mill main engine and classifier are lubricated with oil. The main shaft and three grinding roller parts of the main engine are externally equipped with lubricating oil tanks, and all bearings are soaked in lubricating oil for reliable lubrication and cooling. The user can observe the level of oil on the oil tank and fill the lubricating oil in time according to the requirements.

Roses are red, sugar is sweet, and so are you.

Fate rarely changes because of people's thoughts, because it is always character that makes decisions.

Raymond mill is a common grinding equipment, once the milling equipment is used for a long time, all parts of the Raymond mill will fail, and the entire Raymond mill will age, so at this time, what should we do?

After the aging of Raymond mill equipment, it can be compensated by repair, replacement, renewal and improvement repair.

The physical aging that can be eliminated can be compensated for by repairs to restore its function, especially the basic parts in the Raymond mill, which contain most of the value and cannot be easily discarded; For the indelible tangible aging, maintenance is meaningless and must be replaced in order to compensate; If the visible aging has reached a considerable level, and its invisible aging period has not yet arrived, it usually needs to be overhauled; If the overhaul cost has exceeded the original value after tangible aging, or the first type of intangible aging has occurred at the same time, and the overhaul cost exceeds the reproduction**, it can be replaced; When visible aging and invisible aging exist at the same time, it should be updated and the old Raymond mill equipment should be replaced with high-efficiency Raymond mill equipment; In addition to the occurrence of complete tangible aging, some of the xth type of intangible aging also occurs, and corrective repairs should be used.

Therefore, it is necessary to formulate a maintenance plan according to the law of wear and consumption of parts and parts and the replacement cycle, so as to achieve planned maintenance and status monitoring and maintenance according to the production plan and maintenance plan, according to the spare parts reserve quota and reserve a sufficient amount of vulnerable spare parts.

1) Minor repairs. The minor repair cycle is generally one month, but it also includes repairs as they are broken. The content of minor repairs mainly includes the inspection, cleaning and oil change of oil pumps, oil filters and lubrication pipelines; Inspection, replacement or tightening of various parts of the stump; Inspect the large and small gears of the Raymond mill, record the wear, measure the meshing clearance, and repair the worn gears; Check whether the concentricity of the coupling has changed, the wear of the elastic rubber pad and the plunger, and replace it according to the wear; Open the manhole cover to enter the Raymond mill, check the wear and tear of the cylinder lining, lattice plate, wedge iron, and end cover lining plate and replace it as appropriate; Measurement of grinding media filling rate.

2) Medium repair. In addition to all minor repairs, the main purpose of the repair is to clean up and adjust the parts of the equipment and replace a large number of vulnerable parts. In addition to minor repairs, the specific objects of inspection should also be inspected and replaced, and the repair work of the inlet and outlet pipe bushings, feeding pipes and large and small gears of the Raymond mill should be inspected.

The medium repair cycle is 4-6 months, and some are one year.

3) Overhaul. In addition to the major repair, the overhaul includes all the contents of minor repairs and medium repairs, focusing on repairing and replacing the main components of the Raymond mill.

Therefore, after the aging of the Raymond mill, we must replace the replacement and repair the maintenance according to the specific situation, so as to remedy the aging Raymond mill.

Aging Raymond Mill, if you want to deal with it, you can just turn this Raymond off.

Old wa's. How to deal with it? Aging Raymond mill should. No need to change to a new one.

Aged Raymond ink, you can sell it to scrap collectors, or directly convert it into decorations yourself.

How should the Raymond mill of presbyopia be handled? This one can be replaced with a new one.

If it is aged, it is recommended that you replace the aging parts.

If the old one is replaced, then of course you can only sell it, and then buy a new one.

How Raymond Mill Works:

After the material is crushed and destroyed to the required particle size, the material is sent to the storage hopper by the promotion machine, and then the material is sent into the grinding chamber of the Raymond mill through the vibrating feeder evenly and continuously, because of the centrifugal force when rotating, the grinding roller swings outward, pressing on the grinding ring, and the shovel picks up the material and sends it to the grinding roller and the grinding ring, and achieves the purpose of crushing and destroying due to the movement of the grinding roller. The fine powder after material grinding is brought into the analysis machine for sorting with the reincarnation air of the blower, and the fine and coarse material falls back to the re-grinding, and the qualified fine powder enters the finished product cyclone powder collector with the air flow, and is discharged through the powder pipe, which is the finished product. In the Raymond grinding chamber, due to a certain amount of moisture in the grinding material, heat generation during grinding, water vapor evaporation, and the interface of the whole machine pipes is not tight, the external gas is inhaled, so that the reincarnation air pressure increases, to ensure that the mill works under negative pressure, the increased air flow is discharged into the dust collector through the residual air pipe, and is discharged into the atmosphere after purification.

Purchase problem: If you purchase Raymond mill, it is recommended that you listen to the evaluation of your peers, and there are many technical parameters of equipment in major industries as a reference, and it is best to go to various manufacturers to refer to it on the spot. Red Star Machine warmly reminds you.
