There is a certain difference between the design speed and actual use speed of the Raymond mill. The rotation speed of the small Raymond mill is about 280-220 rpm, the rotation speed of the medium-sized Raymond mill is about 140-180 rpm, and the rotation speed of the large Raymond mill is about 60-120 rpm.

The rotation speed of the Raymond mill is directly related to the output and performance of the Raymond mill. The…

Slag is the residue after beneficiation or smelting. A few years ago, most of the slag produced was discarded or buried, and it was not effectively used, which wasted a lot of resources and polluted the natural environment. In recent years, the particle size of environmental protection has been continuously enhanced. With the advancement of technology, people have a better understanding of slag. We found that slag is an active mixed material of cement after grinding, so the slag in the…

Raymond milling machine is an ultra-fine milling equipment for processing ore milling. The fineness adjustment range is between 50-400 mesh, and it can be fed into powder once. Raymond mill uses limestone and other ore for processing limestone and other ore, energy saving and environmental protection, small footprint, low energy consumption, simple and efficient. The main components in the Raymond mill are grinding rollers,…

Due to the special use environment, Raymond mill must be properly treated before and during use. In the selection of materials in the design stage of Raymond mill, the media environment should be considered, and the materials must have good adaptability, corrosion resistance and thermal insulation.

In the design of the Raymond mill structure, the welding seam should be minimized to prevent corrosion after penetration. At…

Sand making machine is the most important equipment in the sand and gravel production line, and also the equipment with the most serious loss, usually including plate hammer, counter lining, casing lining and rotor body guard plate. Among them, the failure time of the hammer is the shortest, and the repair cost is quite high. Therefore, the most important thing to solve the high-efficiency wear is to reduce the loss of the hammer. So what exactly causes the…

The main component of limestone is calcium carbonate. Lime and limestone are widely used as building materials and are also important raw materials for many industries. Limestone can be directly processed into stone and burned into quicklime. Lime includes quick lime and hydrated lime. The main component of quicklime is CaO, which is generally massive, pure white, and light gray or light yellow when containing impurities. Quicklime absorbs moisture or adds water to become slaked lime, slaked…

Any equipment needs daily maintenance to extend the service life of the equipment, and the Sand Making Machine also needs careful maintenance to ensure that it can work normally. With the application of processing equipment, people are paying less and less attention to it, and it is slowly worn down until it is no longer usable, resulting in serious waste of resources.

Due to its compact structure and fine…

There are two problems in the process of capital construction in our country: First, large-scale urban construction consumes a lot of natural resources, and at the same time generates a lot of construction waste, and the disposal of construction waste becomes a problem. Second, the urban-rural development is extremely uneven, the economic foundation of the vast rural areas is weak, and the basic construction is obviously lagging behind. Analysis of the above situation, standing at the height…

As a modern milling equipment, Raymond mill itself will encounter various problems in the production process, such as performance degradation and wear of wearing parts. Recently, some customers have reported that the fineness of the milling of the Raymond mill is uneven. Then, Shanghai SBM Heavy Industry made an analysis, the specific contents are as follows:

1. Hardness of raw materials

For different materials, the…

The finished product of the sand and gravel production line includes both small-grained sand and large-granularity stone. The sieving of the raw material of the finished product is mainly carried out by the round vibrating screen of the sand and gravel production equipment. The production of sand and gravel materials is divided into links such as crushing, screening and VSI Crusher. The quality control of sand and…

When buying a Raymond mill, you have a dilemma in terms of equipment price and quality. It is difficult to choose. The better the price is, the more expensive it is. In the current market, price has become the key word to measure the quality of things. According to the current market conditions, the economic status quo in recent years reflects that many customers want to change the original production model and are facing a situation of tight economic conditions. Therefore, I would like to…
