The flow and head of the vibration pump were deduced and then the correlation between the pump characteristics and material and construction were analyzed.
In order to ensure the normal work of the pump, the maximum working stress must be less than the allowable material stress.
The tensile resistance of nitrile rubber (reinforced vulcanized rubber) is 15 ~ 30Mpa, =15/2.2=6.828Mpa means allowable stress, n is the safety factor, the plastic material, n = 1.5-2.2, here n equals 2.2, equals 15Mpa, Pressure of working surface is ，=3.0379510-4 m2, F=110794.85103=549.87N =1.81Mpa F is the force produced by electromagnetic actuator mechanism; S is the area of working surface.

Then the retained materials in each sieve and in the bottom pan were weighted.
Sorghum bagasse presented an elevated gross calorific value compared to other biomass materials.
In true density analyses, was observed that the smaller the size particle, the higher the material density, as expected for organic materials.

The loose amorphous straw material was compressed into high-density fuel in a certain shape, greatly reducing the storage and transportation costs, enhancing the fuel quality.
Then, water mist is sprayed to the dry sorghum straw in order to get the straw material to corresponding moisture, and then it is sealed and stored for 3-4 days, so that the moisture and material are fully mixed.
