Research on material s pose probability of electro - magnetic feeder;

Study of material motion stability in electro-magnetic vibration feeder;

Tips for Establishes the Enterprise Material Codes Standard;

A detailed description was made to the general working principle of powder materials pneumatic transportation, working characteristics of Y95 model fluctuating low pressure pneumatic conveyer, Y91C model whirling pneumatic conveyer, and S-series of pneumatic transportation system commonly used in foundry shops.

The self-grinding technique of the materials was proposed on the basis of grinding principle of ball mill.

According to the difference of materials production and their monitoring requirements,the monitoring levels are partitioned and designed and the multi-layer materials monitoring mode is found.

Research of cantilever screen grating diagrid and matter coactions way imitation;

Has studied vibration of a single grating diagrid firstly,analyzed the montion of matter on screen,lastly analyzed and simulated the track of matter on it by using Matlab.

The paper studies the screen with ellipse track and establishes a new fomula for transitting probability of matter,which is suit to the cantilever screen.

The rule of materiel motion was analyzed on sieve.

The motion of grainular material in vibrating bed is simulated using coordinate-change method.
