【Technical analysis】How to choose “industrial monosodium glutamate” calcium carbonate? What is the difference between “heavy calcium” and “light calcium”?
Calcium carbonate is an important and widely used inorganic salt mineral, commonly known as “industrial monosodium glutamate”, is one of the commonly used fillers in all walks of life. Calcium carbonate can not only reduce the raw material cost of rubber and plastic products, but also improve some properties of rubber and plastic materials. Different kinds of calcium carbonate can significantly…

The key technical problems of ultrafine powder – dispersion and agglomeration
The agglomeration of ultrafine powder refers to the phenomenon that the original powder particles are connected to each other during the preparation, separation, processing and storage processes, and multiple particles form larger particle clusters. It is currently believed that there are three main reasons for the agglomeration of ultrafine powders: intermolecular forces causing agglomeration of…
Grinding of API in Oral Solid Dosage Process
In the production process of oral solid dosage forms, bulk drug crushing is often an extremely critical unit operation. On the one hand, the particle size of the API may affect drug absorption. For poorly soluble oral solid preparations, the smaller the particle size of the raw material, the faster the dissolution, and the bioavailability of the drug may also be improved. In addition, the…

Fine grinding of high value-added powders
In today's high-tech environment, almost all products are facing higher standards and requirements. Most products are in some form of powder, such as powder and liquid (paste or slurry), powder and gas (aerosol), powder and powder (mixed powder or filled polymer). As a result, powder handling technology has become a key must-have for many materials producers.
Methods for producing fine…
Factors affecting the performance of cyclone dust collector
There are many factors that affect the performance of the cyclone dust collector. Generally speaking, one is the structure factor, and the other is the operating condition factor.
The structural factors are generally divided into four aspects:
Entrance and top
1) The inlet form is generally divided into two types, direct inlet and vortex inlet.
2) The top of the dust collector…
The details that need to be paid attention to when using the superfine grinder
The ultra-fine pulverizer adopts a unique design scheme. After improvement, the blade is no longer used, and the cutter head and liner are specially installed according to the design structure of the fuselage. In order to improve the grinding efficiency and effect, the ultra-fine pulverizer uses high-speed impact force and shear force to make the material in the grinding cylinder subject to the…
