For users who have just contacted laboratory airflow crushers, this is a strange equipment, but in view of the high-end high-cost equipment, it is inevitable when choosing. And worry, worry that the wrong model is delayed the loss of production and funds (LOSS). As a professional laboratory airflow pulverizer supplier, it is aware of the presence of a laboratory airflow pulverizer for everyone (referring to all over the general). 1. Before selecting the airflow pulverizer, the first choice to understand the classification and principles of the airflow pulverizer.
At present, the current airflow milling industry can be divided into a spiral airflow mill, fluidized bed airflow pulverizer, circulating tube gas flow pulverizer, target Airflow pulverizer in the form of airflow pulverizer, currently using the most widely spiral airflow pulverizer and fluidized bed airflow pulverizer, spiral gas current pulverizer, also known as disc air pulverizer or flat air current pulverizer, The main principle is that the gas stream forms a spiral state in the pulverized cavity, and the material is frictionally friction in the helical tangential direction, and the internal mechanism of the cavity is mechanically designed, the maximum particle size of the CONTROL is, fluidized bed airflow. The pulverizer is the driving effect of the material in the pulverizing chamber, and the upper portion of the cavity is placed in the upper portion of the cavity, and the particle size of the material is controlled. Therefore, both crushing are powered by airflow, achieving a crushing effect, requires compressor to provide compressed gas source, just in the pulverization process and control granularity, it is different, confirming the material objective (Cause) of the experiment (Cause) pulverization fineness Whether the gas flow pulverizer to be purchased is a machine powder pulverizer to ultrafine pulverization (grain the particles material to the particle size of the micrometer).
It is the most commonly used ultra-fine pulverized pulverization that is currently dry. At present, the extervation of the production of airflow millines is different, and some can even reach the nano-stage, the actual situation is: the airflow pulverizer is ultra-fine pulverized equipment, not nano-crushing equipment, the author believes The 200nm or less can be called nanometers, physical methods are difficult to reach nano-level, do not be misleaded by bad manufacturers. Airflow pulverizer, performance parameter is D97 = 2 ~ 45um, that is, fineness can be 97%, 2um or so, if it is 50% or average particle size, at 0.5~ 1 um, such performance is also the limit of the equipment, and is for some special materials, not all materials can reach this requirement, so the gas flow pulverizer is not reached. The airflow pulverizer is not a mechanical pulverizer, and the crushing fineness is generally ultra-fine and pulverized. If only 325 mesh is required, it is believed that if it can be mechanically pulverized, it is used to use mechanical, because in the actual use process, the gas flow pulverizer Production costs are always greater than the mechanical pulverizer 3. Learn if the Experiment Value Value Flow Crusher (Crusher) has easy disassembly cleaning, no dead angle, etc. Multiple samples, easy cleaning is a very important function.
If a sample sample is 5 minutes, the demolition is 5 hours, and the study of research institutes is unimaginable; design airflow smash Machine, whether host structure or auxiliary equipment, such as: cyclone collector, pulse dust collector (role: purifying air), feeding feeder, and other systems, all systems, the basic requirements for easy removal Make the laboratory's users and easy to remove the equipment, the equipment and no dead angles, easy to clean. The airflow pulverizer changes the normal air of the gas source to nitrogen, carbon dioxide gas, which can make the unit become an inert gas protection device, which is suitable for pulverizing grade processing of materials such as flammable and explosive, easy oxidation. 4, the airflow pulverizer has two forms do not choose the wrong gas flow pulverizer; fluidized bed airflow pulverizer; and; spiral gas flow pulverizer; two equipment functions, adapted to different materials, generally, medical or Material compared materials use a spiral gas current pulverizer, and new materials such as batteries require fluidized bed airflow mills for the experimental room, two forms of gas flow crusher design 100 in the Experiment room. Type, and can be combined with two forms of airflow pulverizing machines to accommodate various requirements of different materials of the laboratory. 5, safety, is the important reference factor for the Experiment Value Blow Crusher First, you must first understand the material of your own sample, whether it is dangerous. If there is a dust burning or explosion, it is considered (consider)Use nitrogen to do crushing media (from the substance of determining effect), do not care for cost, reduce your safety awareness, because the airflow pulverizer is ultra-fine and pulverized, the finer the powder, the larger the surface area, the greater the dangerous coefficient, It is to consider the safety protection of the equipment itself, whether an anti-static filter bag is used, whether system pressure monitoring, etc. (refers to a solution for problems).
