Physical phenomena during the working of the ball mill

From the physical phenomena and geometrical characteristics of ore crushing and ball mill grinding process, grinding is the continuation of crushing ore, which is a process of reducing the size of a nugget or ore. However, from the thermodynamic point of view, grinding is a process of internal energy increase. The grinding machine works on the ore block and overcomes the cohesion of the ore block to break it. Therefore, grinding is a process of mutual transformation. The electric energy input by the power grid is converted into mechanical energy by the electric motor, and the mechanical energy works on the grinding machine and the medium through the transmission system, and becomes the mechanical energy of the grinding medium of the ball mill. When the grinding medium falls or rolls down, it works on the ore. The work of the medium becomes the deformation internal energy of the ore, which causes the ore to deform and break. After the ore is broken, it becomes the new surface energy of

Influencing factors and precautions of precision casting dimensional accuracy defects

Under normal circumstances, the dimensional accuracy of precision casting is affected by many factors such as the structure of the casting, the material of the casting, the molding, the shell, the roasting, and the casting. Any setting or unreasonable operation will change the shrinkage of the casting. The dimensional accuracy of the casting is deviated from the requirements. The following are factors that can cause defects in the precision of precision castings: (1) Influence of casting structure: a. The wall thickness of the casting is large, the shrinkage rate is large, the casting wall is thin, and the shrinkage rate is small. b. The free shrinkage rate is large, which hinders the shrinkage rate. (2) Influence of casting material: a. The higher the carbon content in the material, the smaller the linear shrinkage rate, and the lower the carbon content, the larger the linear shrinkage rate. b. The casting shrinkage of common materials is as follows: casting shrinkage K = (LM-LJ) / L

The advantages and functions of precision casting

The lifting position of the blade is too high, and some are biased. Low, so that the material scooped by the blade can not be accurately sent to the grinding position, which greatly affects the production capacity of Raymond Mill. Second, the size of the blade has a direct relationship with the production space of Raymond Mill. If the space is too large, it will not be put in, and it will affect the normal operation of Raymond Mill . If it is too

The main reason for the production of pores in stainless steel castings

In the stainless steel casting process, the pore problem often occurs, which causes a lot of troubles for the stainless steel casting processing. The pore is the bubble defect formed by the deposited gas remaining in the ingot during the cooling and solidification of the metal liquid. Let's analyze the main reasons for the generation of pores: 01. The permeability of the coating is poor or the negative pressure is insufficient. The gas permeability of the filling sand is poor, and the gas and residue in the cavity cannot be discharged in time, and the pores are formed under the filling pressure. 02. The pouring speed is too slow to fill the sprue cup, expose the sprue, entrap the air, inhale the slag, and form the venting hole and the slag hole. 03. Foam model gasification decomposition generates a large amount of gas and residue can not be discharged into the mold in time, foam, paint layer filled dry sand is poor drying, surrounded by high temperature of liquid alloy, cracking a

Stainless steel precision casting process

SBM sand making machine's six requirements for sand and gravel

图片
VSI sand making machine is a kind of widely used mechanical equipment, which plays an important role in the sand making, crushing and rough grinding industries, but the most used one is the sand making industry. Since the companies that produce the equipment are mostly mining machinery manufacturers, there are certain requirements for sand and gravel. 1. The particle requirements for the broken material are fine. In general, the requirements for the needle shape are not strict. The reason for the strict grain size and grain size of the ore is that the cubic sand is the best for concrete and asphalt. The machine-made sand not only increases the strength of the concrete, but also reduces the amount of cement. Secondly, the cubic sand has an interlocking effect on the particles due to the angular edges. 2. According to the definition of the mechanism sand, the rock particles with a particle size of less than 4.75 mm, which are made by mechanical crushing and sieving, are not included in

Ramond grinding machine is mainly composed of main engine, fan, reducer, analysis machine, grinding roller, grinding ring, scraper, grinding roller assembly, high-pressure grinding device, plum frame, etc. From the structure of ramond mill , it can be seen that the bearing device is the core part of the equipment, the use of grinding roller and the user's operation mode has a certain relationship, but there are often users reflect the phenomenon of bearing into the powder in the mill. Now small make up for everyone to analyze the reasons. The reasons for the powder entering into the inner bearing of ramond mill can be roughly divided into two situations: one is the lack of lubricating oil or the damage of the sealing ring; Second, the bearing device for a long time lack of maintenance and cleaning. Bearing feeding powder is generally caused by these two operational problems. First, let's talk about the bearing sealing ring. Sealing ring is generally rubber products, due to the

SBM Raymond mill machinery manufacturers

The grinding machine produced by SBM Heavy Industry adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of raymond mill in the same industry. This equipment has higher efficiency than ball mill, low power consumption, small floor space and low investment. . The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so that when the grinding roller and the grinding ring are worn to a certain thickness, the yield and fineness of the finished product are not affected. The replacement cycle of the grinding roller and the grinding ring is long, so that the shortcomings of the replacement period of the wearing parts of the centrifugal pulverizer are eliminated. The air-selected airflow of the machine is circulated and flowed in the fan-grinding shell-cyclone-fan, so it has less dust than the high-speed centrifugal pulverizer, the operation workshop is clean, and the environment is pollution-fr

Comparison between jaw crusher and impact crusher

First, the jaw crusher The working principle of the jaw crusher is: the motor drives the belt and the pulley, and the moving jaw moves up and down through the eccentric shaft. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw. At the same time, the material is crushed or chopped to achieve the purpose of crushing; when the moving down, the angle between the bracket and the moving jaw becomes smaller, and the movable jaw is separated from the fixed jaw by the action of the rod and the spring. The broken material is discharged from the lower opening of the crushing chamber. Performance characteristics of jaw crusher: large crushing ratio, uniform product size; convenient component replacement, small maintenance workload; simple structure, reliable operation, low operating cost; low noise, less dust; large range of discharge opening, can meet different User's request. Jaw crusher scope

Two basic specialties of stainless steel casting process

Because the shortening of fine casting of stainless steel is much greater than that of cast iron, in order to avoid the defects of shrinkage and porosity, riser, chill and subsidy are mostly used in casting technology to complete sequential condensation. In order to avoid shrinkage, porosity, porosity and cracks in stainless steel casting , uniform wall thickness, sharp and right angle structure,lujianshi.75ix.com liujiaomoju.75ix.comhuafenchim.75ix.com gelidun.75ix.com yadingmoju.75ix.cn liushui.75ix.cn sawdust addition in moulding sand, coke addition in moulding core, and hollow core and oil sand core selection should be made to improve the concession and permeability of sand moulds or cores. Due to the poor fluidity of molten steel, in order to avoid cold insulation and lack of pouring, the wall thickness of steel castings should not be less than 8 mm; dry or hot casting models should be selected; proper pouring temperature should be improved, generally from 1520 to 1600 C. Due to

Analysis of various types of precision casting materials

Castings have a great influence on mechanical products. Mechanical properties depend to a large extent on the quality and performance of castings. Therefore, mechanical products have high requirements for castings. Mechanical products require that castings have working durability under different conditions, including Wear resistance, corrosion resistance, chilling heat, fatigue, shock absorption and other properties as well as machinability, weldability and other process properties. These quality properties have a direct impact on the working efficiency and service life of mechanical products. Different casting materials make the performance characteristics of the stainless steel casting itself different. Cast steel production is relatively stable, while the quality, variety, performance of steel castings and the proportion of alloy steel and special steel continue to increase. The use of various refining processes and technologies to develop new cast steel materials can improve the t
