The high quality of the modern construction mixes is impossible without using special modifying additives. They allow to adjust the properties of the material, making solutions with the required qualities for use in any (even extreme) conditions.
A relatively large amount of such additives is available in the market today. These are mostly surfactants, electrolytes, polymers etc. The history of modifying construction materials begins in the ancient...
Quartz is a natural mineral. It is widely availalbe and has several important properties: high strength, resistance to destruction and high sorption capability. Quartz can be a part of other minerals, making its content in the planet’s crust above 60%. It is mostly used as sand in industrial applications.
Fine pulverization of minerals allows to change their adsorption capacity and intensify processes. Due to fine and superfine grinding, the material’s properties...
Wood flour is a powder consisting of particles the size of hundred microns, and obtained by pulverizing sawdust.
The area of application of wood flour is rather wide This material is used in the preparation of phenolic plastics, alkyd linoleum, filter elements and explosives. In smaller amounts wood flour is used in the manufacture of electrodes, adhesives, catalysts, and casting molds.
Production technology of wood flour:
- Preparation of raw material. The basic raw...
The characteristics of ferromagnetic particle vortex layer allow the use of this device for mixing of various granular materials, using less energy compared to other methods and equipment, as well as preventing separation of the blend.
Numerous efforts of engineers and scientists in the area of equipment and method development for mixing of granular material often strike the obstacles caused by the nature of such materials and their flow.
