Answer:Relative to the pressure-type homogenizer, colloid mill first is a kind of centrifugal equipment. It has the advantages of simple structure, convenient maintenance and is suitable for high viscosity materials and large particles materials. Also, its main drawback is determined by its structures. First, as for the centrifugal movement, the flow is not constant, corresponding to viscous material, the flow vary greatly. For example, the same equipment, in dealing with viscous lacquer and thin dairy fluid, the flow speed can differ 10 times above. Second, because of the high-speed friction between the stator and material, it is easy to generate large quantity of heat, and make the material processed. Third, the surface is easy to wear, and after wearing, the refined results will be significantly reduced.
High Pressure Homogenizer transports the processed material to homogenizing vale in high pressure way by triple plunger pump, making the material receive complex force such as turbulence, cavity, cut when the material flow past the little space between the valve plate and the valve seat to reach the purpose of emulsification and homogenizing.
