SNG's grinding and dispersing machine is especially suitable for materials that need to be grinded, dispersed and homogenized in one step. The grinding disperser is a vertical split structure, with precise parts and components running smoothly, and the running noise is below 73db. At the same time, the German Bergman double face mechanical seal is adopted, and the sealing part is cooled by the refrigerant, so as to reduce the leakage probability to a low level, and ensure the continuous operation of the machine for 24 hours.
The structure of gmd2000 series grinding disperser: the grinding disperser is a high-tech product composed of cone grinding and disperser.
The first stage is composed of three-stage serrated protrusions and grooves with fineness increasing step by step. The stator can be adjusted to the required distance from the rotor without limitation. With enhanced fluid turbulence, the grooves can change direction at each stage.
The second stage is composed of rotor stator. The design of dispersing head can also meet the needs of different viscosity materials and particle size. The difference between the design of the working head of the on-line stator and rotor (emulsion head) and the batch machine is mainly due to the requirements for the transportability. It should be noted that the difference between the coarse precision, medium precision, fine precision and other types of working head is not only the arrangement of the designated rotor teeth, but also the geometry characteristics of different working heads The signs are different. Slot number, slot width and other geometric features can change the different functions of stator and rotor working heads. According to the past practice, according to the previous experience to specify the working head to meet a specific application. In most cases, the structure of the machine is matched with the specific application, so it is very important for manufacturing the final products. When it is uncertain whether the construction of a working head meets the expected application.
From the perspective of equipment, the factors affecting the dispersion effect are as follows:
1. Form of grinding head (batch type and continuous type) (continuous type is better than batch type)
2. Shear rate of grinding head (the greater the effect is, the better)
3. Gear structure of grinding (divided into primary teeth, middle teeth, fine teeth, ultra-fine teeth, the finer the teeth, the better the effect)
4. Residence time and grinding dispersion time of materials in the dispersion wall (it can be regarded as the same motor, the smaller the flow, the better the effect)
5. Number of cycles (the more the effect is, the better the time limit of the equipment will be.)
