Analysis of the advantages and disadvantages of raymond mill

Conical grinding machine is composed of Shanghai Jianye heavy machinery limited company absorbing foreign advanced technology, independently developed high grinding machine is applicable to coarse powder production equipment in the field. Conical grinding machine is our new type mill, a microcosm of the our company continuously innovation. The conical mill is a mill relatively tall, tapered shape, material from the top to bottom out, grinding, also at the upper end of the transmission system.
Compared with the traditional raymond mill has the following advantages:
1 capacity is large, the energy consumption is low. Take the JYM5055 cone mill and YGM4528 mill minimum pressure to compare (Raymond machine series of relatively large), in 100 to coarse powder processing at the same time, the yield of JYM5055 can reach 20-30 tons per hour, and the power of motor is 110KW, and the YGM4528 high pressure mill, production can not be more than 15 tons in 132kw, the main power. As a comparison, we know that the conical grinding machine is coarse grinding, professional production of high, low energy consumption.
2 the service life is long, tapered roller mill can be used for 1 to 2 years, the wear is very small, the main and the grinding roller of skin, and the slow speed. Raymond mill grinding roller and is relatively small, relatively fast speed cone mill, the wear rate is high.
3 conical milling machine feeding mouth slightly larger, more material can be. JYM8085 cone ball mill feeding is less than 50mm, and Raymond mill must be less than 35mm.
4 Cone Mill of slag, pyrite and difficult to grind material pre grinding, effect than using high pressure mill ideal.
The conical mill many advantages, but is always in the field of coarse powder. No powder selecting system of conical milling machine, so much for the production of coarse powder, powder processing more than 150 objective will be difficult. Only the weaknesses of conical milling machine has become a coarse powder expert. The conical mill although only the production of coarse powder, but in some areas the optimization process is very large, especially in the slag grinding processing, pyrite, desulphurization and other environmental protection and waste lime powder can play a huge role. Conical grinding machine is an efficient coarse powder mill after the total environmental protection.

Raymond mill features and structure

1. The high frequency ore screen adopts the advanced design principle, which is a vibrating screen with new structure.

2. Vibrating exciter does high frequency vibration and can screen static by driving sifter through transmission mechanism. Raymond mill is designed to work in resonance state, and the whole equipment has damping support, which makes the ground bear no dynamic load, and the screen machine needs no fundation. The high frequency ore screen can be directly installed on the smooth ground or common platform with steel structure.

The sifter is with high screening efficiency, big operational capacity, so it’s especially suitable for the screening of fine powder materials.
4. The sifter is made of three different flexible screens. The compound net is working net, which do screening by directly touching with materials; and the bottom is backing screen, which is used for separating stress and transferring vibration.
5. The installation angle of screening machine is easy to adjust, and the installation angle usually is 23-27 degrees. We can adjust the leaning angle of screener on the basis of parlicle size of minerals. When the inclination is close to 55 degrees, the size can get to 300 mesh, and the screening efficiency can be up to 75 percent.
6. The vibrating parameter of screening machine is controlled by computer and can be adjusted independently.

Three Important Application Areas of Raymond mill

Limestone is the main raw material of manufacturing cement, lime production, and calcium carbide, also it is an important building materials, meanwhile, the high-quality limestone after ultrafine grinding is widely used in paper, rubber, paint, coatings, pharmaceuticals and other product’s manufacturing.

Some companies have launched the new Raymond mill, it is designed and developed according to the Chinese limestone characteristics and working conditions, adopting the unique rotor structure and wear-resistant materials technology and casting production technology, it has improved the equipment performance and crushing effect and has been applied to the ultra-crushing operations of limestone. According to the market research, the most extensive applications of the limestone sand making machine on the market is the following three industrial areas.

First, it is used to the crushing and sand making of the limestone and river sand in aerated concrete block field. The stone particle size of the Raymond mill produced is uniform, it fully comply with the requirements of the mortar stone quality, and the powder quantity is high, which can increase the performance of the aerated concrete blocks in the production process. It not only can have a good influence on the limestone crushing, but also can greatly reduce the mill energy consumption and save production costs.

Second, it is widely used in the field of limestone crushing cogeneration (limestone production line). Limestone sand making machine, depending on the stable crushing effect, big production and affordable characteristics, has become the popular limestone crushing and sand making equipment among the concrete mixing plants, and sand making factories. And the limestone sand making an enclosed design, effectively reduce the noise and dust pollution, in line with today’s national industrial development of energy saving green development road.

The processing of cement clinker still needs the support of Raymond Mill

It is understood that, last year, the national cement clinker production reached 12.8 tons. Among them, the kiln cement clinker output of 9.6 tons of cement clinker. In the process of cement production, most of the raw materials to be broken, such as limestone, clay, iron ore and coal etc.. Limestone is cement production, the largest amount of raw materials, mining of large size, high hardness, so crushed limestone in cement plant material crushing occupies important position. Reasonable selection of the crushing process of crushing equipment and grinding equipment is very important. Before the material enters the grinding equipment, as may be the bulk materials broken to small, uniform particle size, in order to reduce the load of the grinding equipment, and improve the yield of Fen machine. Material crushing, it can reduce the process of particles with different size segregation phenomenon in transportation and storage, of uniform composition of raw materials, ingredients to improve the accuracy.
The processing of cement clinker still needs the support of Raymond Mill.
In the process of cement production, material grinding power consumption accounts for about 70% of the comprehensive energy consumption, directly affect the manufacturing cost of cement. In an increasingly tense energy, prices continued to rise in the circumstances, actively adopt new technology and new process, improve the yield of grinding system, reduce the unit power consumption is to reduce production cost and improve the economic efficiency of enterprises is the most effective way. How to actively adopt new technology, new technology, new materials, greatly improving the grinding efficiency and decreasing the electric energy consumption cost, is placed in front of the cement engineering and technical personnel of an urgent task. Feeding size is an important parameter Raymond mill grinding efficiency. Especially for cement grinding process, because the grinding material physicochemical properties and microhardness different, easy to wear index deviation on the raw material composition of the material. So we must take reasonable means, the implementation of pre grinding material pretreatment, narrowed into grinding size more crushing and less grinding, Raymond mill storehouse broken all or part of the move to complete, can greatly improve existing grinding system output, reducing power consumption of grinding.
With the development of science and technology, industrial slag cement demand is increasing, the milling machine manufacturers according to the present situation, development of various milling machines are used to cement pregrinding processing to high yield and high production effect. Shanghai Ding Bo has a milling machine for many years production and sales history of manufacturers, first proposed by vertical milling machine, vertical mill) alternative high stable Raymond mill used in cement pregrinding, effectively improve the 40% – 60% of the output of cement grinding and process design reached world leading level, by users praise.
The processing of cement clinker using vertical milling machine is no longer but from the aspects of environmental protection and emission reduction considering, we r & D and production of large-scale environmental protection cement clinker grinding machine – vertical milling machine energy saving and environmental protection, convenient operation, more stable performance, higher capacity, vertical milling machine to bring the cement industry is tangible benefits to promote.
