The good crushing effect can be said to be the most obvious advantage of the jet mill, but at the same time the disadvantages of high cost, high energy consumption, and easy wear of the equipment have always been the well-known weaknesses of the jet mill. In recent years, with the continuous improvement of the technical level of the industry, the quality and performance of products have been significantly improved, and the market application prospects have been optimistic.
At present, the main objective of the development of the crushing industry in the world is to increase the fineness while increasing the output and expand the scope of application. For example, it can be used for the development and application of fibrous, high hardness, high toughness, viscous and elastic materials crushing, cryogenic crushers. The crusher with a gas atmosphere is also the focus of many foreign manufacturers.
In general, compared with ordinary mechanical ultrafine grinding, jet milling can crush the product very finely, and the particle size distribution is narrow, ie, the particle size is more uniform. And because the gas expands at the nozzle, it can cool down. The smashing process does not generate heat, so the smash temperature rise is very low. This characteristic is particularly important for ultrafine pulverization of low-melting and heat-sensitive materials.
There are several types of jet mills used in industrial applications in China: flat jet mills, fluidized bed jet jet mills, circulating tube jet mills, jet jet mills, and target jet mills. These types of air flow pulverizers are widely used in flat air jet mills, fluidized bed jet jet air mills, and circulating tube jet mills.
However, when the crushed jets are used to crush materials, especially high-strength materials, there is a problem of high energy consumption and serious equipment wear. The internationally major producers of crushing machinery mainly include Japan and Germany. In Japan alone, there are hundreds of crusher plants. The output has reached an astonishing number. The product package has a large capacity, a wide range of applications, and unparalleled technological advantages. It has been leading the R&D and production of jet mills and has caused tremendous pressure on domestic companies.
In recent years, with the continuous improvement of the level of domestic industrial manufacturing, there has been significant progress in the production technology of jet mills and other equipment, which has basically become the dominant domestic market, and the industry's development prospects are promising.
