Function and Maintenance of Raymond Mill Parts

Raymond mill as a classic equipment in the mining industry, pays more attention to the development of quality in the market. Raymond mill is a very large equipment. First of all, because its working environment is very bad, the materials used for grinding are bulky materials, so the size of the mill should be larger. Second, Raymond mill is a complete set of equipment. There are main grinders and other auxiliary equipment. The whole equipment of Raymond mill includes: hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-grinding machine, frequency conversion classifier, double cyclone collector, pulse dust removal system, high-pressure fan, air compressor, electrical control system.

Such a large Ramon grinder, are composed of many parts, regardless of the small parts, can play a major role. The service life of Raymond mill has a certain period of time, like people have a certain life, how can the service life of Raymond mill be extended? We need to add more maintenance to each component.

As we all know, the hardness of ore material itself is slightly higher, Raymond mill itself and ore collision friction, loss is inevitable. How to solve this problem, or how to reduce the loss, has become the thinking direction of many manufacturers. Vulnerable parts are the hard parts of Raymond mill and vulnerable parts, so more protection is needed to make the performance of Raymond mill play.

In the operation process of Raymond mill, there should be a fixed personnel responsible for the custody, Raymond mill operators must have a professional technical training, so that they understand the principle of Raymond mill performance, familiar with operating procedures, at the same time necessary maintenance tools and grease accessories. Secondly, it is necessary to simply screen and check materials when they enter, avoid unnecessary wear and tear, and routine safety checks are necessary.

After using Raymond mill for a period of time, it is necessary to regularly check the use of vulnerable parts, serious wear and tear should be replaced and repaired in time. The whole Raymond mill is a whole, if part of the problem, to stop maintenance in time, must not cause unnecessary losses due to negligence. General professional Raymond mill equipment and accessories are matching, so in the selection of Raymond mill must choose a professional manufacturer to buy, and to understand the Raymond mill accessories standard.

How to improve the efficiency of sand making machine?

With the drying up of natural sand, artificial sand has been widely used in construction, highway, railway, water conservancy and other industries to replace natural sand, so the market demand of stone sand making machine is quite large. Under this background, we have developed and manufactured special stone sand making equipment. This sand making machine can process most of the stones excavated from the mountain (especially hard outside), such as limestone, Lapis lazuli, marble and so on, and eventually the finished sand can be compared with natural sand in grain shape.

Sand-making machine is different from the typical impact sand-making machine. It uses hammer to impact stone to make sand. It is commonly known as hammer sand-making machine or double-rotor sand-making machine. Customers who choose this equipment on the production line of machine-made sand have a good reaction. The advantages of this type of equipment are mainly shown in three aspects.

1. the structure is simpler and more humanized. Mainly including the chassis, hammer head, two rotors and sieve plate, etc., the sand machine is equipped with an investigation door under the turning can be readily observed equipment processing stone condition, together with easy equipment maintenance.

2. the feed size is larger. General sand machine feed size is usually about 50 mm, and the stone sand machine can allow the size of 150 mm, or even 250 mm feed. This shows that the stone between 50mm-250mm can avoid crushing process and reduce equipment investment.

3. The hammer head of the first working part is made of high hardness and good wear resistance material, which has a long service life and reduces the economic and time cost of replacing parts and directly improves the yield of customers.

Improve production efficiency of Raymond Mill

Raymond mill is one of the equipments used for grinding stone. It is widely used in many fields such as construction, building materials, chemical industry, mineral processing, metallurgy and so on. It plays an important role in improving the quality of ore. Raymond mill is usually characterized by high efficiency, low cost, easy operation, large output, low energy consumption, environmental protection and so on, which has attracted much attention and welcome in the industry.

Raymond mill as a mill equipment, to do regular maintenance, regular maintenance, attention to each small problem small hidden trouble, correct operation, in order to avoid unnecessary accidents, then how to choose lubricating grease maintenance?

1. The lubricant temperature of Raymond mill should also be paid attention to. In the use of the lean oil system of Raymond mill, we must pay attention to its return oil temperature, which should not exceed 60 degrees. The oil temperature can be controlled by adjusting the oil valve to control the flow of oil or by means of water cooling. Only in this way can we ensure the mill’s normal production.

2. The use of Raymond mill grease to consider its economic applicability, in the case of lubrication effect, as far as possible to reduce the use of grease varieties, so as to minimize the cost of production and use.

3. Where grease is used, the variety of grease to be added should be selected according to the different ways of adding grease. In Raymond mill, the roller and grinding ring are the main breaking parts of the roller bearing in this place often move, which requires timely lubrication measures. If not, the friction between the machine parts will soon be damaged. But it is important to note that the lubricant added to this place should be dry oil lubricants. Some workers will suggest that dry oil solidifies easily in winter, when a certain amount of thin oil should be added to the lubricant to avoid the lubricant solidification in the course of use can not produce the desired effect.

4. when choosing grease, pay attention to the working state of Raymond mill. The vibration intensity of Raymond mill is relatively high when it is working. The grease with high viscosity, good adhesion and good shock absorption performance should be selected when selecting grease. In this way, the use time and effect of grease will not be affected by the strong vibration force of Raymond mill.

5. The purpose of using lubricant in Raymond mill is different, which requires using grease according to different purposes. In addition, if the grease is used in a more sealed state, it should be considered whether the grease can coexist with the sealed medium.

Working principle of portable crusher plant
