The grinder-pastepreparer KIP is the essentially new kind of the equipment used in emulsions and suspensions production of various technical appointments. It is also a fine homogenizer. Work of KIP is based on a cavitational principle. The cavitation phenomena are known in hydrodynamics as the phenomena destroying designs of hydrocars, courts, and pipelines. The cavitation can arise in a liquid at turbulent streams and also at influence of ultrasound on a liquid. Skillful management of a cavitation gives the chance to apply these machines in technological processes.
