For  transportation of grain and products of  its pomologist on modern  grinding enterprises are widely used pneumotransport.  In principal  hydraulic power which develops blowing machine are consuming by pneumotransports- to 90%.  Reducing the power consumption of its element of the installations is getting particular important meaning. The main condition for reducing energy consumption  is  implementation  of  optimal  in energy ratio modes of transportation in verges of real practical load ranges, diameters and lengths of material conductors, which is characterized for pneumotransport  installations of grinding mills. Analysis of modes of their work are expecting reducing of operating speed of air in material conductors to values acceptable minimum while ensuring stability of the process of moving products.

     However work at minimum speeds of air requires more exact tune of pneumotransport installation on adopted rational mode. Ensuring sufficient for transporting products of air velocity in the material conductors, which are united by a common collector at the change in their work load are revealed practically impossible without automated devices or without significant reserves speeds with manual regulation. Any oscillation of load in any material conductor changes its hydraulic resistance and leads to redistribution cost of air in other pneumotransports. During the work with minimum speeds of air (without stock) redistribution of costs can engender resistance stability of transporting (obstruction) in some material conductors.

       In recent years control systems with using of mathematical set vaguely logic (fuzzy logic) began to be used for control by various objects (1) in particular various drivers.

       Features and options for building of control systems are defined by types of independent functions and using of input signals of fuzzy controller.

       The system with fuzzy  logic is essentially nonlinear and cannot be studied  analytically that’s why was used the method of structural modeling in software package  Matlab, applications Simulink,  Fuzzy Logic, Toolbox, which are necessary for analysis and synthesis control systems which are based on fuzzy logic.

       Conducted researches of energy efficient systems showed the following:

- Minimum allowable speed of aero mix in most loaded product conductor is 12 m/s.

- System performance is sufficient to avoid any obstructions in pneumotransports during the sudden increase of its load.

- The use of fuzzy controller permits maintain the minimum speed of aero mix during stochastic loading of pneumotansportswhich  allows  to save the energy.
