How can reduce the maintenance cost of raymond mill?
Raymond mill adopts electric control and realizes electric automatization management, for this reason, the quality of the electric parts such as disconnector of the electric motor will influences the normal operation and maintenance of the whole set of equipment. For this reason, when choosing electric parts for ore milling equipment, the customers should consider the quality of the products as well as the company strength and product stability.
As is known to all, at present such equipment as Raymond mill does not have single standard, nor does electric part such as disconnector. As for the products produced by different manufacturing companies, the models and specifications of the products will be different. Seen from the current development situation in domestic market, the products manufactured by big, medium and small-sized companies are all upgrading and updating. For this reason, choosing a Raymond grinding mill supplier should consider not only the strength of the company, but whether this company has the ability to ensure long time stability of the product quality and perfect after-sales services. In addition, the products of the manufacturing company should be leading in technology and mature in development, and should have certain market shares in at least ten years.
Raymond mill is a large-sized machine with relatively long changing cycle. As its cost is high, it is normal for the customers to use a machine for a number of years and even decades. In the long time of running process, some damageable parts of Raymond mill need regular maintenance and change, and some small parts like disconnector of the motor may also be damaged. If these parts need maintenance or change, but because the products of the suppliers are unstable in quality which leads to short supply of goods, then the after-sales service of the Raymond mill manufacturing company will be in trouble, it will also cause loss to the Raymond mill customers due to man-hour delay.

Causes and solutions of wear failure of ultrafine grinding bearings
Bearings are more important parts in a machine. Different bearings have different roles, but under normal circumstances, bearings mainly bear the following functions: transferring energy and bearing weight.
The internal bearing of the ultrafine mill developed by the company also undertakes the above two functions, and the customer needs to understand that the parts of the machine are operated by mutual installation and cooperation, so it is impossible between the parts Operate alone, and a certain force will be generated when the accessories interact, and for the bearing, when it transfers energy, this force is friction. When this friction is relatively large, the bearing will inevitably Failure due to wear.
In general, in order to reduce the probability of bearing wear and failure, we will lubricate the bearing to reduce the friction between the bearing and other accessories, so as to protect the bearing. The ultrafine mills developed by the company all use advanced technology, namely automatic thin oil lubrication technology, to provide lubricating oil to the bearings through the lubrication station connected to the machine, thereby realizing the lubrication of the bearings, reducing the failure of bearing wear and reducing the Customer manual operation.
In addition to the function of transmitting energy, the bearing also has a load-bearing function, such as the main shaft in the ultrafine powder grinding grinding chamber, which bears the role of transmitting energy and load-bearing at the same time, and when bearing, the frictional force that the bearing receives at the same time will also increase It will also cause bearing failure. In addition, the material of the bearing determines that it has a certain load-bearing range. If the load-bearing path of the bearing in the ore grinding powder exceeds this range, there will be another failure of the bearing, that is, fracture. In this situation, we often recommend that customers avoid high-hardness minerals entering the ultrafine grinding chamber, and customers also need to ensure that the feed particle size of the machine is within the specified range, in order to try to avoid serious bearing failures, and ultimately extend The service life of the machine.

Hubei silicon carbide ultrafine grinding roller damage how to do
Hubei silicon carbide ultrafine mill is a kind of grinding equipment for grinding silicon carbide into silicon carbide powder. It is mainly used to meet the materials of major industries after silicon carbide processing. Under normal circumstances, silicon carbide can be ground into an arbitrary adjustment within the range of 2500 mesh. However, long-term use of the grinding roller and grinding ring of the equipment will cause wear and tear, which affects production. How should this problem be solved? Let's take a look at the wear of the silicon carbide grinding roller grinding ring of Hubei silicon carbide superfine grinding powder.
1. Reasons for damage of grinding roller grinding ring
When the Hubei silicon carbide ultrafine grinding process occurs, the wear can be divided into mechanical damage, fatigue damage, thermal damage and chemical damage. For example, mechanical damage is caused by the sharp points on the surface of the material being processed, which causes the local stress concentration of the grinding roller, causing strong tearing and cutting. The sharper the material to be grinded, the greater the hardness, the greater the wear rate, and the faster the wear rate; and fatigue damage, due to the wear applied by the ultrafine grinding roller and the surface of the grinding ring for a long time, is a low-intensity wear. Therefore, these reasons have caused damage to the ground silicon carbide in Hubei silicon carbide ultrafine grinding.
2. The following provides the Hubei silicon carbide raymond mill grinding roller wear method
First of all, every time the wear is reduced, the wear roller device of the Hubei silicon carbide ultrafine grinding equipment is used for more than 500 hours to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time , The refueling tool can be manually lubricated; the second step, fineness adjustment, according to the size of silicon carbide material, soft and hard, water content, specific gravity, the processing thickness is also different, you can adjust the upper analyzer, high speed, The fineness is high, the rotation speed is low, and the fineness is low, the user can flexibly grasp, not only the fineness of the stone slip powder can be reached, but the grinding roller grinding ring will not be damaged.
Application of ultrafine mill in the field of talc
Magnesium silicate is the chemical name of talc powder. Talc mines are very rich in reserves around the world, usually a mixture of various crystal forms. Generally, the deep processing of talc ore powder must be ultrafine milled, which is ground into fine powders of various sizes, and then applied to various fields.
The influence of industrially produced talc powder on the performance of the coating is controlled by its structure type, powder fineness and particle size distribution. Therefore, we will classify the talc powder products: fibrous talc powder, flake talc powder, granular talc powder.
Merchants process talc powder through ultrafine grinding mill, and the particle size ranges from coarse, medium and fine. There are varieties on the market that have undergone surface treatment and have low oil absorption, which is suitable for photomagnetic poles. Talc is easy to wet and disperse in all liquid coatings, such as organic solvents, varnishes, alkyds and water-based systems. Talc powder has excellent suspendability in coatings, and can also help other pigments in the system to remain suspended.
Talc powder with coarser particle size is suitable for some coatings that require rough coating or "toothed", such as interior wall paint, primer and crepe paint. Varieties of medium particle size are suitable for house paints and can also be used as general fillers. Superfine talc powder is suitable for controlling the gloss, consistency and sagging properties of semi-gloss coatings. The amount of talc is large in cement, crack filler and putty. Special products decide to choose coarse or fine talc powder according to different requirements.
It can be seen from the application of talc powder that both coarse and fine powders are widely used. SBM Raymond ultrafine mill can process coarser talc powder, fine powder ultrafine mill can process finer powder, ultrafine mill can process talc ore to more than 1500 mesh powder, SBM ultrafine mill series products It is getting more and more applications in the field of talc processing.

Factors influencing the working efficiency of construction waste crusher
The construction waste crusher is a crushing station for the utilization of construction waste resources. It integrates construction waste receiving, crushing, transmission, processing, reprocessing and other technological equipment as a whole. Through different equipment combinations, it becomes a powerful set of mobile production processing Line, complete multi-demand construction waste processing and processing operations. However, the working efficiency of the mobile construction waste crushing station is sometimes different. The following describes the factors affecting the efficiency of the construction waste crusher.
1. Consistency of pressure and screening rate
Construction waste crusher will continuously transport, crush and sieve garbage during the production process, and garbage will be subjected to different degrees of pressure during this process. Of course, the greater the pressure, the greater the effect of crushing. The better. Some users have inconsistent pressures and sieving rates during operation. This is mainly because when the equipment is processing garbage, the garbage is in a compressed form and the shaping is restricted, so that the work efficiency will be greatly affected.
2. The level of speed
The speed of rotation has a certain effect on the pass rate of finished products and energy consumption. In the case of constant pressure, if you change the diameter of the motor pulley of the crusher and then adjust its speed, you will eventually find that the faster the speed, the less complete the crushing is. The amount of particles gradually increased. Therefore, during the production process, it is necessary to pay attention to the speed not to be too high, so as not to cause the product quality to decline.
3. The size of the load
The size of the load also means the amount of feed, and the working efficiency of the equipment has a great relationship with the load. When the crushing station is running, if the load exceeds the required load, then there will be different degrees of equipment jamming. Productivity. Therefore, in order to ensure the normal progress of production, the amount of feed must be strictly controlled during the operation of the equipment.
