The grinding process is achieved by the use of a hammer in beating the material fed into fine particles; the fineness aimed depends on the detachable screen with aperture sizes ranging from 87µm to mm. Based on the power ratings and output shaft speed of the existing grinding machines in industries like flour mill, it was found that the main sha...
WhatsApp: +86 18838072829The machine is of hammer mill type. In this case, there is hammerlike 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.
WhatsApp: +86 18838072829The crushing process is achieved by the use of a set of hammers in a crushing chamber which beats the mineral feeds into smaller particles small enough to pass through the aperture of the replaceable sieve positioned beneath the crushing chamber. The size aimed depends on the aperture of the replaceable screen.
WhatsApp: +86 18838072829Our paper presents the hammer mill working process optimization problem destined for milling energetic biomass (MiscanthusGiganteus and Salix Viminalis).
