The three-roll grinding machine is mainly used for refining high viscosity materials in various paints, inks, pigments, plastics and other industries. It is especially suitable for processing products with high viscosity and fine particle size. It is one of the equipment with high grinding fineness in the current wet grinding equipment. The friction caused by the mutual extrusion of the surfaces of the three rollers and the different rotating speeds makes the adjacent rollers produce strong shear force to force the materials to be fully dispersed and ground.

The principle of the spray drying tower is to mechanically disperse the materials to be dried into very fine mist-like particles, (increasing the evaporation area of ​​the water, accelerating the drying process) and contacting with hot air, and removing most of the water in an instant, so that The solid material in the material is dried to powder. The spray drying tower can once dry the liquid with a moisture content of 40-60% (up to 90% of the special material) into a powder product, without crushing and screening after drying, reducing the production process, increasing the product purity, simplifying the production process, and operating Easy to control, suitable for the production of powdery, granular solid products from solutions, emulsions, suspensions and pasty liquid raw materials. The spray drying tower is the most widely used process in the liquid process forming and drying industry. In a hot air stream, 95% to 98% of water can be evaporated instantaneously, and the drying time only takes ten to twenty seconds. Especially suitable for the drying of heat-sensitive materials.
The spray drying tower adopts two-stage cyclone dust removal device, or one-stage cyclone dust collector and wet dust collector; it has good uniformity, fluidity and solubility, high product purity, good quality, simplified production process, and convenient operation and control. A device that can dry and pelletize at the same time. According to the process requirements, the pressure, flow rate and orifice size of the feed pump can be adjusted to obtain the required spherical particles in a certain size ratio.
Irrespective of the material requirements for spray drying, their chemical composition and physical properties are very different. So far, spray drying is still said to be a skill, to some extent it is. In the feature budgeting and descriptive process of the spray dryer, it is difficult to use the theoretical formula because of the practical characteristics of the material and its movement in the boring tower. Therefore, the practical experience often has a great effect. The parameters and past experiences in the depiction process are often not discussed with the theoretical discussion. The characteristics of the current spray drying tower budget and description, not only based on theoretical analysis alone, but also rely on experimental data and manufacturers of long-term accumulation of practical experience.
When you choose spray drying, you must contact the engineering and technical personnel of the supplier for all the specific technical exchanges. See if the technical level in this area is tailored to meet your needs. Look at the integrity of materials, equipment, and systems.
Spray drying tower that uses heat energy to reduce moisture
The spray drying tower is a drying device that uses heat energy to reduce the moisture of the material and is used to dry the object. The drying tower vaporizes the moisture (generally refers to moisture or other volatile liquid components) in the material by heating to obtain a solid material with a predetermined moisture content. The purpose of drying is for material use or further processing needs. Spray drying towers are a method of systematic application of material drying. After the thin material is atomized in the drying chamber, the moisture rapidly vaporizes in contact with the hot air to obtain a dried product. The method can directly dry the solution and the emulsion into a powdery or granular product, and evaporation and crushing can be omitted.
