In the main frame, a 1000-1500kg high pressure spring is fixed to the roller suspender. After the grinder is put into effect, the ring affected by the high pressure spring and centrifugal force. And its rolling pressure is 1.2 times higher than that of the Raymond grinder under the same power condition and the output is raised to higher degree. When the stuff is loaded into the grinding cavity. It is shoveled into the space between the roller and the ring for grinding. The resulted powder is routed to the separator along the circulation wind of the blower and the standard fine powder is guided to the cyclone collector as final product and large size stuff falls back to the grinder for regrinding
1.The whole raymond grinding plant is a vertical systematic structure to occupy small area. From crushing of raw material to grinding and packing, it is an independent production system. 2.The grinding device of the main unit is fixed with 1000- 1500 kg pressure springs. When the machine works, the grinding roller which under the action of high pressure spring and centrifugal force, rollers close up to grinding ring. Stable capacity and fineness are guaranteed 3.The main unit and upside clasifier are connected by spring, and sealed with soft belt, which reduce the noise and avoid sympathetic vibration, reduce the vibration of machine vastly. 4.Gap between vane and shell are the main factor of product fineness.Grinding device adopts superimposed seal, sealed performance is good

As the calcium carbonate rock whose main component is calcite, limestone (CaCO3) is the main constituent of karst. It is the gray or gray-white sedimentary rock formed by the accumulation of biological shells or bones in the sea and lake basins.
With the wide application in building materials, highways, metallurgy, and chemical industries, the limestone powder grinding industry has developed rapidly and achieved good economic benefits. So, what do you need to know before engaging in limestone powder grinding?
To engage in the limestone powder grinding industry, the most important thing to understand is how the limestone is ground into the powder. Limestone powder (calcium carbonate) ground into different fineness can be roughly divided into two types: light calcium carbonate and heavy calcium carbonate.
Therefore, according to the types of limestone powder, methods of limestone powder grinding can also be divided into light calcium carbonate powder grinding and heavy calcium carbonate powder grinding.
Light calcium carbonate is an important basic chemical raw material and is mainly used as a functional filler for modification or reinforcement. Here are the processing steps of light calcium carbonate powder:
Relying on the chemical reaction process, this method has a long flow, large energy consumption, serious pollution. Besides, the instability of performance severely restricts the application of light calcium carbonate.
With the development and changes in the requirements of related application fields and downstream industries, heavy calcium carbonate has evolved from fine powders mainly based on d50 = 74 μm and d97 = 45 μm to ultra-fine powders and ultra-fine active powders.
The ratio of heavy calcium and light calcium application in some developed countries has reached 4: 1. Therefore, light calcium production will disappear sooner or later. To engage in the limestone powder grinding industry, it is wise to choose heavy calcium carbonate grinding.
Limestone can be applied to many fields after being ground into the fine powder and obtain considerable economic benefits. In recent years especially, the limestone powder grinding industry has gradually become popular.
Being used as a slag-making agent for steelmaking, 1 ton of steel consumes about 40-50 kg of lime. And being used as raw materials for calcium carbide production, almost 1 ton of ash need one-ton lime.
Light calcium carbonate or nano calcium carbonate powder, depending on the fineness, can be used for paint or plastic product additives, and be used in papermaking, pharmaceutical, rubber production. The economic value of nano-scale calcium carbonate is quite objective with the price from several hundred to more than one thousand dollars per ton.
According to the input size, output size and needing capacity, the powder grinding equipment in the current market can be roughly divided into 3 types: Raymond mill, HGM German high-efficiency powder grinding mill, and three-rings and medium speed micro powder mill.
Besides, the methods of powder processing can also be divided into 3 types: coarse powder grinding, fine powder grinding and superfine powder grinding according to the fineness of the finished product.
As one of the most mature grinding mills, Raymond mill can grind more than 280 materials with Mohs hardness of 9.3 or less and moisture below 6% spread from mineral, chemical, construction to many other industries.
The new Raymond mill with the above improvements not only improves the grinding efficiency greatly but also consumes less energy. With a capacity of 8-176 tons/day and good performance at a low price, it is more suitable for the small powder grinding plant.
HGM German high-efficiency powder grinding mill is a new type of powder grinding machine which is designed by the latest international processing technology and concepts. The working principle is shown in the following:
Compared with the traditional Raymond mill, HGM grinding mill has a larger capacity with 40 t/h and further reduces energy consumption. Therefore, it is the best choice for large-scale powder processing plant.
As a representative machine for superfine powder grinding, the fineness of three-rings and medium speed micro powder mill can reach about 2000-3000 mesh. However, so fine its output size is, the capacity is only 500-7000 kg / h.
Cause the powder is so fine, its application and amount of use are very limited. As a result, three-rings and medium speed micro powder mill is not the mainstream equipment for powder grinding industry.
Ensuring the grinding efficiency and reducing dust pollution are the two most important aspects during the powder grinding. Ensuring grinding efficiency is the first factor for obtaining the expected economic benefits, and reducing dust pollution is an important measure of protecting the environment and achieving sustainable development.
After deciding the powder grinding fineness, the grinder capacity is a very important step that affects the profit. Ensuring the capacity has great significance for improving economic benefits. Then how to ensure the grinding efficiency of the grinder in the grinding operation?
The non-renewable and non-creative of limestone determine the "expensive" trend of high-quality limestone powder. With quality depending much on the degree of limestone resource, the production of high-quality heavy calcium carbonate is the "stability anchor" of the lime industry in the future.
