Food-grade online grinding disperser

SGN Grinding and Dispersion Machine is an integrated equipment combining grinding and dispersion, representing a new technological innovation. The grinding dispersion machine integrates a colloid mill (cone mill)+ high-shear disperser into one unit. It first grinds and then disperses the material, instantly dispersing it after grinding to prevent secondary agglomeration.SGN grinding dispersion machine can reach a speed of 14000rpm, with a linear velocity of 44m/s, and strong shear rate. It is also known as the "High-Speed Grinding Dispersion Machine" and can be widely applied in the food industry.

Jiangsu Sijun's GMSD2000 Inline Grinding Dispersion Machine is a high-tech device integrating the functions of a colloid mill, disperser, and homogenizer. It is specifically designed for high-viscosity and hard-to-disperse materials, particularly excelling in the exfoliation and dispersion of nano-level powders. Its core technology originates from Germany's Industry 4.0 concept. Through an innovative design of three-stage grinding + multi-stage shearing, it achieves dual breakthroughs in efficiency and precision in fields such as graphene, lithium batteries, pharmaceuticals, and food.

Structure of the GMSD2000 series grinding dispersion machine: The grinding dispersion machine is a high-tech product combining a cone mill and a disperser.

The first stage consists of three levels of serrated protrusions and grooves with progressively increasing fineness. The stator can be infinitely adjusted to the desired distance from the rotor. Under enhanced fluid turbulence, the grooves change direction at each level.

The second stage consists of the rotor and stator. The design of the dispersion head also well meets the needs of substances with different viscosities and particle sizes. The main difference between the inline stator and rotor (emulsification head) and the batch machine's working head design lies in the requirements for transportability. Special attention should be paid to the differences between coarse, medium, and fine precision, as well as other types of working heads. These differences are not only in the arrangement of rotor teeth but also in the geometric characteristics of different working heads. The number of slots, slot width, and other geometric features can alter the functions of the stator and rotor working heads. Based on past practices and experience, working heads are selected to meet specific applications. In most cases, the machine's construction is matched to the specific application, making it crucial for producing the final product. When uncertain whether a working head's construction meets the intended application.

The GMSD2000 grinding dispersion machine features a vertical split structure with certain conveying capacity, capable of handling materials with high solid content and certain viscosity. The GM2000 is designed with a special rotor that conforms to the fluid characteristics of the slurry to push and convey the material; all parts in contact with the material are made of 316L stainless steel, and the base uses 304 stainless steel. For special requirements, such as materials with high hardness, materials with strict requirements for iron impurities, and working conditions where the pipeline has certain pressure and requires uninterrupted operation, the grinding head can be optionally coated with carbide or ceramic. The improved GMSD2000 colloid mill features a jacket design outside the chamber for cooling or heating media.

Technological Innovation:

The integrated design of the colloid mill and disperser offers more advantages compared to a series connection of the colloid mill and disperser. A series connection involves a time lag. After the material passes through the colloid mill, the finely ground material tends to agglomerate, and subsequent dispersion by the disperser is less effective. In contrast, the GMD ultra-fine grinding dispersion machine instantly passes the finely ground material through the dispersion working group for dispersion before agglomeration occurs. This instantaneous action yields much better results.
