Raymond mill utilizes the principle of wind selection powder selection
A variety of crushing equipment screening principle is diverse, and which relies on the wind as a screening condition of the main Raymond mill, rotary mill, European version of the mill, micro mill, trapezium mill, three ring medium-speed and other vertical structure of the powder machine, wind selection of crushing equipment need to be equipped with a high-pressure centrifugal fan, as the power of the powder conveyor, with the special quality of the powder selection device can be realized in the finished product screening of the material, the wind can be said to belong to the mill's exclusive! Component institutions, other crushing, sand making devices are not suitable, in many mills, although the principle of the mill is the same, but the composition of the structure is also slightly different, for example, mine mill and micro-powder mill analyzer blade rotation is obviously different, which is why the ultra-fine mill to achieve thousands of mesh powder screening principle.
Raymond mill wind screening principle in detail:
Raymond machine finished material screening is mainly completed by two parts, one is the centrifugal fan, the second is the analyzer, the fan will be wind input grinding chamber, grinding powder under the action of the wind is blown to the upper end of the mill host analyzer, and at this time the analyzer blades rotate constantly, the powder to pass through the analyzer must be from the gap between the blades to pass quickly, from the principle of conservation of kinetic energy in physics can be known: F = MV, however, fan Wind volume is a certain that F is a fixed value, when the smaller the powder particles, that is, the smaller the M, the faster the speed, the quality is inversely proportional to the speed, and vice versa, the lower the speed, the more difficult to pass through the analyzer high-speed rotating blades, and thus the Raymond Mill wind selection principle is to rely on the fan wind volume and high-speed rotating analyzer to achieve (the faster the speed of the analyzer, the finer the finished product is), and then the qualified powder in the negative pressure under the action of the wind will be transported with the pipeline constantly Then the qualified powder will be transferred with the conveying pipeline under negative pressure until the cyclone powder collector. In addition, the analyzer blades of the micronizer mill rotate vertically, which prolongs the distance of the powder through the analyzer blades without changing the rotating speed, and requires the powder to pass through at a higher speed, which also realizes the sieving of ultra-fine powder.
Other powder making machine principle introduction:
For example, jaw crusher, impact crusher and even hammer crusher, etc. are relying on the outlet to control the particle size of the material, and then with the vibrating screen to screen out the appropriate particle size of the material, the vibrating screen working principle is simple, and the principle of conventional screen is similar to the principle of this is no longer to do more details, but it is worth mentioning that the principle of the ball mill grinder sorting, the ball mill belongs to the milling equipment, but the main focus on the crushing of metallic ores, the ball mill and the other mills are different, its Output is affected by the diameter of the drum, and the fineness of the finished product is controlled by the length of the drum, that is to say, the longer the material is ground in the ball mill, the finer the fineness is more detailed, the finest ball mill powder in about 200 mesh, belonging to the main grinding device of the metal ores powder selection.
