Studying some mechanical factors affecting chopping sugar beet tops into silage [electronic resource].

Includes references.

The main objective of the present research is to achieve the effect of, the effective engineering parameters such as chopper types, cutting speed, and knife clearance on frequency length of product, power requirement, chopper cutput and specific energy to save power and get suitable cut length to chopped sugar beet tops into silage. These investigated parameters have direct effect on the power requirement (kW) and chopper output (Mg/h). Increasing of cutting speed from 18.84 to 23.55 m/s tend to increase power requirement from 20.20 to 22.50 kW, for cylinder cutter heads and from16.0 to 18.90 kW for flywheel cutter heads. While the increasing of knife clearance from 0.5 to 1.5 mm tend to decrease power requirement from 20.2 to 10.3 kW and from16.0 to 11.0 kW for cylinder and flywheel respectively. at moisture content 70 %. The optimum parameters for chopping sugar beet tops into silage, were" cutting speed 23.55 m/s and knife clearance 1.5 mm at moisture content 60 % which gave less power required 8.85 kW ,less specific energy 3.54 kW.h/Mg and highest values of output 2.50 Mg/h, for flywheel cutter heads
