What is a colloid mill?
Colloid mill is some food industry, chemical industry, medical industry used more mechanical equipment, colloid mill is mainly used for specific materials for cutting, grinding, crushing, vibration, emulsification and other processing, so that the product can be finely crushed and evenly emulsified. What are the characteristics of colloid mill machinery?
Characteristics of colloid mill material:
In addition to the transmission device, the housing and the motor, other parts in contact with the material are generally made of sanitary grade stainless steel, which has the characteristics of high strength. In particular, the rotor (dynamic grinding body) and stator (static grinding body) are characterized by wear resistance and corrosion resistance. The characteristics of corrosion resistance make the colloid mill protect the safety of the internal machine when processing some corrosive materials, and also allow the material processing to proceed steadily. When processing some large particles of materials, the material can be fully ground to achieve uniform and meticulous characteristics. And this also reflects the characteristics of colloid wear, so it is generally called stainless steel colloid mill.
Colloid mill operation characteristics:
Colloid mill is used to rotate the internal rotor, the other stator is not moving, there is a gap between it can be adjusted, and the combination of the rotor and the stator, the dynamic and static velocity gradient generated to process the material, it has a certain centrifugal force, spiral force, the material is fully homogenized, grinding, cutting and crushing and other fine processing. Because of the sufficient friction between the rotor stator and the material in the operation of the colloid mill, a lot of heat will be generated, so that the material is homogeneous and emulsified, and the material is refined once, so that the material can be fully crushed and evenly emulsified. Generally speaking, a small colloid mill can adjust the gap between the rotor and the stator to 50μm, while a large colloid mill can reach 100μm to 200μm.
Colloid mill structure characteristics:
Because colloid mill is in the internal processing of materials, so its sealing is good, and its structure is mainly divided into motor, transmission device, cooling device, dynamic grinding disk (rotor), static grinding disk (stator), regulating mechanism, housing and other components, relatively simple structure, easy to operate, maintenance is relatively easy, and the body is relatively small, can work continuously, High efficiency.
Characteristics of various colloid mills:
The characteristics of the horizontal colloid mill are mainly in the design of the axial positioning of the full consideration to prevent the motor shaft axial penetration of the teeth, in the front end of the motor to cover the bearing, such a design motor rotor and shaft axial thermal expansion will move to the motor front bearing key in the direction of the motor rear bearing, thereby reducing the impact on the grinding head clearance. The vertical colloid mill is relatively higher than the horizontal type, the motor is vertically installed, the motor rotor weight will make the motor shaft will not occur axial penetration, so there is no axial positioning problem, its structure is relatively compact, more light.
Structure of separate colloid mill and vertical colloid mill
Split colloid mill because the motor and the mill body are discrete, good stability, no axial problems, the motor has a long service life, because the motor and the mill body are discrete, so it will not let the material leak to the motor damage. The colloidal mill due to the structure and material characteristics, is generally semi-fluid and fluid materials processing, the flow of sparse materials and viscous materials processing is different, because the colloidal mill body produces centrifugal effect, the material according to the thick and thin, the flow is not constant, so the viscous material and thin material generated by the flow is still different.
