Nano wet pulverizer

Wet grinding is a safe and efficient alternative to dry grinding. Dry grinding generates a large amount of dust, requiring the installation of an appropriate filtration system. This is particularly important when grinding materials that produce a mixture of dust and atmospheric oxygen. Reaching the prescribed safety level typically requires carefully designed technical solutions, such as dust removal and inert gas coverage systems. The cost of these filtration systems often greatly exceeds the actual cost of the grinding machine.

GM2000Nano wet pulverizerSpecially designed for laboratory research and development, simulating production processes, and providing reliable data validation for mass production. The configuration of the pilot model machine is the same as that of the large-scale production model, and the types of dispersing heads and corresponding line speeds are also the same. The process parameters during the pilot process should not be readjusted after mass production, and the risks during the machine model upgrade process should be minimized.

Wet grinding of such substances using rotor stator devices has many benefits:

The fine particles obtained from grinding are directly fused into the suspension, thus avoiding the formation of dust from the beginning.
Unlike dry grinding systems, the material being ground remains within the system, significantly reducing losses. Therefore, wet grinding is very suitable for grinding organic chemicals, especially high-quality substances, or toxic substances.
Compared to the dry grinding process, wet grinding products are easier to feed and measure.

The SGN disperser can be directly integrated into the material synthesis process. This allows the wet grinding process to be carried out simultaneously with other processes, thereby enabling the deletion of subsequent steps. In addition to saving time, the required number of systems and the surface size of the products in contact can be significantly reduced. Pipeline wet grinder is very suitable for CIP or SIP cleaning. The benefits of a wet mill make it an attractive investment product.

The SGN wet mill is based on the rotor stator principle. The SGN wet mill has a high input shear energy and can achieve particle sizes of 10 µ m and below. The SGN wet mill is capable of processing products with a wide viscosity range. Due to its processing capacity, SGN wet mills are used in many applications, such as wet grinding of fabric coatings, paints, paper dyes, and lubricants.

GM2000Nano wet pulverizerCharacteristics:

① Equipped with Bergman dual mechanical seals and a sealed hydraulic system, although it is a pilot equipment, it still has production reliability.

SGN seals are double end containerized seals with good pressure resistance and excellent sealing performance at ultra-high speeds. Equipped with a pressure balance tank, filling with appropriate pressure can ensure the force balance between the upper and lower end faces of the machine seal. At the same time, during operation, the automatic circulation of cooling water can be achieved through the pump ring effect and thermal siphon effect brought by its own eccentric structure. The circulation system is an independent system with no contact with the outside world. The cooling liquid in the balance tank can be purified water or a suitable solvent, effectively avoiding the damage to the machine seal caused by unstable pressure and small particle impurities in ordinary cooling tap water.

② The frequency conversion control cabinet specially equipped for experimental and pilot machines can not only set different functional modules, display temperature, control speed, but also display various parameters that match the functional modules, which can be used for data recording in mass production.

③ GM2000/4 is a vertical split structure with a long operating time, which is not easy to cause shaft eccentricity and is easy to replace. Moreover, as long as the corresponding belt is replaced, ordinary personnel can operate it. The vertical split structure is driven by a belt and achieves acceleration with a ratio of 3:1, which means the normal speed at 50Hz is 7890RPM, and the external frequency conversion can reach 13789RPM.. The diameter of the PP2000/4 rotor is 55mm (the speed is about three times higher than other manufacturers' around 2900 revolutions per minute)

④ It has a very high shear speed and shear force, and a particle size of about 0.2-2 microns can ensure the stability of high-speed dispersion and emulsification. This device can be applied to various dispersion emulsification processes, as well as for the production of homogeneous mixtures including emulsions, suspensions, and colloids. The high shear dispersing emulsifier increases the solute transfer rate due to the shear force generated by the fixed/rotor system, thereby accelerating the decomposition of single molecules and macroscopic molecular media.
