An attempt in design and assembly of equipment for cutting and grinding tree branches leaves and barks in production of composts as nursing medium in forest nurseries

Abstract

The construction and working principles of the machine for cutting and
grinding tree branches, leaves and barks were designed to match the
material and working practices in Vietnamese forestry production. The
machine were incorporated with the continuous cutting and grinding parts,
all of them have light and compact construction, assuring high quality and
low energy costs. In the preliminary tests, the average out put was 1.07 ton
per hour for leaves and small branches and 0.76 ton per hour for barks
within 5 days post - harvest. The output and product quality index were
higher than requirement and energy consumption were kept at reasonable
level. The machine can be used effectively in mechanization of compost
production after forest harvest, optimizing the usage of forest plantations.
