With the development of industrial technology, micro-nano powders have special volume effects and surface effects, and their optical, magnetic, acoustic, electrical and mechanical properties are very different from normal conditions, and are used as the key to many new functional materials. Based on the basic raw materials, the corresponding micro-nano powder processing technology has also…

Jet mill (JM) powder making is a new type of powder making method that uses high-pressure airflow (usually high-purity nitrogen) to accelerate powder particles to supersonic speed in the airflow grinding chamber, causing the powder particles to collide with each other and break. The specific process is: mix the crushed hydrogen flakes (SC) with a certain proportion of antioxidant, then add it…

Fly ash, also called fly ash, is a powdery waste formed by calcining in boilers. Fly ash is typically captured from the flue gas by an electrostatic precipitator or other particle filtering device before the flue gas reaches the chimney. Fly ash is composed of crystals, glass bodies, and residual carbon. It is gray or gray-black and irregular in shape. Most of the particles are…

Ultra-fine grinding equipment uses mechanical force to grind materials to the micron level and classify them. Due to its good processing performance, it is widely used in high-end coatings, food, medicine, chemicals, building materials, medicinal materials, mining and other industries. With the rapid development of the global economy, my country's powder industry is booming, and powder equipment,…

Compared with other types of pulverizers, the main advantage of a jet pulverizer is that it can pulverize crystallized materials to an average particle size of 1 to 10 microns and within a very narrow particle size range at the same time. Typically, a jet mill will grind friable or crystalline materials down to an average particle size of 1 to 10 microns. Certain products, such as certain…

Jet milling technology is a superfine pulverization technology that has developed rapidly in recent years. Because of its advantages such as high crushing strength, fine particle size, narrow distribution, low product pollution, and the use of inert gas, it is widely used in medicine, chemical raw materials and It has been widely used in the preparation of special powders. The jet mill is to…

The application of jet milling technology in API can significantly improve the appearance and properties of solid preparations, as well as various pharmaceutical parameters such as solubility, dissolution rate, absorption rate, adhesion, and bioavailability. Jet milling technology and its characteristics 1. The crushing temperature is low, and the Joule-Thomson effect of the high-speed jet…

The jet mill is mainly a crushing equipment that relies on particle collision for crushing operations. Its basic working principle is to accelerate the compressed air into a subsonic or supersonic airflow through the Laval nozzle, and the ejected jet drives the material to move at a high speed, so that the material collides, frictions and shears and crushes. These pulverized materials will be…

The micronization of raw materials can significantly improve the solubility of poorly soluble drugs, and the dissolution rate of solid preparations prepared from ultrafine powdered poorly soluble drugs can meet the requirements of domestic consistency evaluation. The jet mill is one of the most important components in the ultrafine pulverization equipment, which can pulverize the material to a…

In recent years, as the superior performance of ultrafine particles has been continuously affirmed, more and more researchers have begun to pay attention to the research work of fine powder manufacturing. As an important preparation method of ultrafine powder, jet milling technology has become one of the preferred methods for developing various high-performance micropowder materials. The jet…
