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.

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.

The installation and disassembly method of Raymond mill grinding roller

The surface of the grinding roller by drawing a thin and dense helical, with strong grinding ability. New drawing roller tooth arrangement of blunt blunt. When the roller tooth wear, reduced productivity. This problem can be put on the use of roller or slow roll round, which makes the tooth shape are arranged in front of the blunt. When the roller tooth tip further wear, lower productivity, and will soon make a U-turn, teeth arranged in front of the front. When the tip into a larger plane, productivity has fallen below 50 kg per hour train, and the electricity consumption increased significantly, should be re drawing. Once a wire drawing production 3 in case of 40000 kilos of flour. The grinding roller disassembly according to the above need to remove the grinding roller. Should first remove the protective cover on the left side of the fuselage of the Raymond mill, triangular belt, flat belt and roller shaft double pulley. Then remove the right side of the fuselage gear box and gear size. Then remove the rod spring assembly, remove mill door, remove left, before and after the patch and four bearing seat assembly. Then you can gently remove the door by grinding mill. Install the grinding roller and the disassembly of the replacement of the opposite. Before installation of the surface with clean and coated with oil. The best bolt is also contaminated with oil after assembly, but the oil can not be too much.
Raymond mill cylinder grinding roller and grinding ring determines the motion state of the mill power consumption and productivity level. The vibration frequency and amplitude, and the grinding roller and grinding ring depends on the state of motion of the mill grinding roller and grinding ring shape, density and filling rate. When the Raymond mill, cylinder rollers and ring also fierce movement. With the grinding motion around the center of the ring group simplified grinding roller, not only mainly for the impact, and a single grinding roller and grinding ring rotating around its axis geometry violently. At the same time, grinding roller and grinding ring as a whole, also have the rotary motion opposite to the rotation direction of the vibration exciter. If the exciter rotates clockwise, then grinding roller and grinding ring group circulate counterclockwise. Such movement is with regularity. Each layer is fixed on the rotary radius of almost certain. At the beginning of the grinding media group as a whole rotation frequency is approximately equal to the vibration frequency of 1%. This makes Raymond mill body grinding roller and grinding ring and by grinding material as a whole in the cylinder to rotate slowly, will have the benefit of material blending and grinding to ensure the product quality is stable effect.
The grinding roller disassembly according to the above need to remove the grinding roller, should first remove the protective cover on the left side of the Raymond mill body, triangle belt, flat belt and roller shaft double pulley, and then remove the right side of the gear box and the milling equipment fuselage size gear. Then remove the rod spring assembly, remove mill door, remove left, before and after the patch and four bearing seat assembly. Then you can gently remove the door by grinding mill. Install the grinding roller and the disassembly of the replacement of the opposite. Before installation of the surface with clean and coated with oil. The best bolt is also contaminated with oil after assembly, but the oil can not be too much.
