The pendulum grinder belongs to the roundel immovable mill and has high universality. It also has the characteristics of continuous powder making dry-type, the concentration of grain size, continuous fine fineness, compact structure and so on. The particle size of the pendulum grinding mill can be adjusted in the range of 0.125-0.044mm (equivalent to 120-325 mesh) according to different requirements.

The Application Ranges of the Pendulum Grinding Mill

The pendulum roller mill is widely used. Common grinding materials and usage ways are as follows:

Soil types: clay, China clay, bentonite, magnesia, clay, bauxite, etc.

Non-metallic ores: gypsum, talc, graphite, fluorite, calcite, limestone, calcite, barytes, apatite, tabular spar, feldspar, quartz and so on.

Metal oxides: manganese iron ore, chromite, Ilmenite, bauxite and so on.

Chemical compounds: coke, lime coke, smelting coke, barium sulfate and so on.

Others: the products of the pendulum grinding mill can be used in many industries. For example, the metallurgical industry produces the magnesia as the refractory layer of blast furnace; the oil industry uses the barytes powder to seal the injector; some industries produce bentonite powder as the lubricant for drilling; the chemical industry produces different stone powder as the filler in rubber, plastics, paper making and paint; porcelain, glass, enamel, white cement, gypsum and magnesia products are all processed by pendulum grinding mill.

The pendulum grinding mill is mainly used for grinding non-inflammable and explosive mineral materials, Moh’s hardness of which is below 7 level and humidity of which is below 6%.

Operation Principle of the Pendulum Grinding Mill System

The bulk material is broken by the Jaw crusher to a certain size (powdery or fine particles can not pass through the Jaw crusher), and the material is conveyed vertically to the hopper by a bucket elevator. Then, the electromagnetic vibration feeder delivers the materials quantitatively, evenly and continuously into the main machine for grinding. The pulverized fines are carried out by the blower’s airflow and graded by an analytical machine placed above the main engine. Suitable fine powder that meets the requirements will be entered into the large cyclone separator with the air flow. After separation, the powder will be discharged through the discharge pipe, that is a qualified product. The air flow enters the blower by the return duct at the upper end of the cyclone separator. The whole airflow system is closed loop and operates under negative pressure. Because the grinding material contains moisture, when milling the moisture will evaporate into gas. That gas then leaks in each connection of the whole pipe, which makes an increase in the volume of air in the circulating air stream.

This increased air volume will be introduced into the small cyclone separator from the air duct between the blower and the main engine. The fine powder with the air flow is collected by the small cyclone separator. Then it will be discharged by another outlet pipe. The gas will be discharged into the atmosphere through the exhaust pipe of the upper end of the small cyclone separator.

Scientists studied diligently with a quiet mind, and then they designed a new micro powder mill. So they solve the problem of high cost successfully. It is a high-efficiency and high-pressure micro powder mill. 

The Application Scopes of Micro Powder Mill

The micro powder mill is mainly suitable for grinding of conventional materials and the ultra-fine powder processing of non inflammable and non explosive materials, such as kaolin, limestone, calcite, talcum, marble, barite, gypsum, iron oxide red, iron oxide green, aluminum hydroxide, pigment, bentonite, clay, coal, activated carbon and so on, the humidity of which is less than 8%, and the Moh's hardness of which is less than level 6.

The Structure Characteristics of Micro Powder Mill

The high-pressure micro powder mill mainly consists of the main engine, blower, superfine analyzer, finished cyclone powder collector, bag filter and connecting duct. According to user needs, it can provide with auxiliary equipment such as the hoist, storage bin, electric cabinet, feeder, crusher and so on. In the grinding mill room, the grinding roller assembly is hung on the grinding cradle through the cross arm shaft. The grinding cradle, spindle and the relieving tool post are fixed. The pressure spring is tightly pressed on the outer end of the cantilever housing of the grinding roller bearing chamber by a tension rod. Taking the transverse load axis as the supporting point, the grinding roller is firmly pressed on the inner surface of the grinding ring by the spring pressure.

When the motor is rotated through the drive, the blade of the blade is synchronized with the grinding roller, and the roller rolls around the surface of the grinding ring and rotates around itself. The analysis machine drives the rotating of the impeller through the motor drive. The speed adjustment of the analysis machine determines the fineness of the powder. The relieving tool in the relieving tool post and the grinding roller rotate at the same time. Then the grinding roller rotates on the inner surface of the grinding ring and revolves around itself. The analysis machine drives the impeller of the analysis machine through the motor drive device, and the speed adjustment of the analyzer determines the fineness of the powder.

The Main Features of Micro Powder Grinder Mill

The application scope of the high-pressure powder mill is much larger than that of the airflow mill.

Compared with other mills, the grinding pressure of grinding roller on the material can provide 800---1200Kg under the action of high-pressure spring. It saves energy. Under the same circumstance of output and fineness, the energy consumption of the system is only 1/3 of that of the airflow mill.

The investment is small and the efficiency is high. Under the same circumstance of output and fineness, the price is only 1/8 of the airflow mill.

Compared with the air mill, the production link is less. Firstly the airflow mill must crush the material of 20mm to the superfine powder of 100 mesh, and the high-pressure micro powder mill can make the material reached the average particle size about 6.5 μm to 12.5 μm for one time, of which the size is below the 20mm.

The grinding device adopts overlapping type multiple stage seal and has good sealing performance.

The dust removal effect of the mill can totally reach the national dust emission standard.

The most important function of laser automatic welding machine is to use the laser beam with very high energy density as a heat source to achieve the welding effect. Generally speaking, the use of continuous laser beam can reflect the role of welding to better achieve good welding effect at the same time. Usually there are certain technological parameters for laser automatic welding machine. Then, what are the main process parameters of laser automatic welding machine with high quality and quantity?

1. The power density requirement of laser automatic welding machine:

Power density is one of the most important parameters of laser automatic welding machine. For example, high power density can heat the surface to boiling point in microsecond time and produce a lot of vaporization, which can make the precision welding and seamless welding of processing materials better.

2. Pulse waveform of laser automatic welding machine:

Pulse waveform of laser automatic welding machine is an important element for laser welding of thin sheet material. For example, when high intensity laser beam is applied to the surface of material to be welded, most of the reflectivity of metal surface will decrease and its reflectivity will change with the surface temperature. So we should pay attention to the change of metal reflectivity caused by laser pulse waveform in laser automatic welding machine.

3. Pulse width of laser automatic welding machine:

Pulse width of laser automatic welding machine is an important parameter to distinguish material of removal and melting in laser welding. It is also a key parameter to determine the cost and volume of processing equipment. This parameter is suitable for precision machining, and the general material can be neglected.

4. Defocus of laser automatic welding machine:

Defocusing is usually a process parameter that has an effect on the quality of laser automatic welding machine. In order to prevent the evaporation of holes caused by the high power density of the spot center at the laser focus, people should pay attention to the need for defocusing during laser welding.
