From David Mills ‘Pneumatic conveying system design guide’ the solid loading ratio (ɸ) is 0.5. Therefore, ṁ = ρ × A × v = 8000 Kg/hr = 2.2 Kg/s Were ρ is the density of the mixture, A is the area of cross-section of the pipe and v is the velocity of discharge.

The machine is of hammer mill type. In this case, there is hammer-like projection mounted on a shaft. The hammer revolves at high speed and grinds the materials fed into pieces by beating. Moreover, the machine can mill only the dry materials. The machine is incorporated with a detachable sieving mechanism to ensure fineness of cereal grain ground.

hammers are also common in hammer mill designs. Hammer mills are recognized as technology capable of finely grinding the greatest variety of materials [3,13] and are noted for achieving high size-reduction ratios and yielding cubic-shaped particles [14,15]. Hammer mills have a wide application in biomass size reduction because of their simple

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

The general rule of thumb is to maintain a velocity below 5 ft/s (1.5 m/s). Gravity (g) and the slope of the pipe. An increase in slope decreases the pressure due to gravity. Pipe Diameter (D): The larger the pipe diameter is, the slower the flow velocity will be. Optimal flow rate can be maintained without increasing the velocity, if a larger

Pine wood chips were ground with a hammer mill and a knife mill with a small screen size of 1.5-mm screen, respectively [8, 9]. The results showed that knife mill used 238 kWh t −1 whereas hammer mill used 119 kW h t −1. The specific energy reported for grinding pine with knife mill seems more than what is expected.
