Biomass Shredder PAES 244-245:2010 Flashcards
machine used to cut biomass materials into strips (
biomass shredder
part of a shredding machine which is used to cut or sliced twigs or small branches of trees
into small and uniform sizes called chips
chipping section
organic materials used as renewable source of energy and other agricultural applications
biomass
part of the biomass shredder where the biomass materials to be cut are loaded
hopper
electric motor or internal combustion engine used to drive the biomass shredder
prime mover
weight of biomass material fed into the shredder, expressed in kilogram per hour
input capacity
ratio of the weight of the input biomass materials less unshredded biomass materials, to the
total weight of the input biomass materials to the shredder, expressed in percent
shredding efficiency
Biomass shredder that is installed permanently and commonly provided with adjustable
anchors to level up the machine during operation
Stationary type
Biomass shredder that is commonly hitched to transport vehicle to facilitate mobility.
Trailer type
Biomass shredder that is being manually pushed and/or pulled by a person to facilitate
mobility.
Cart type
The blades and shaft assembly rotates with respect to the vertical axis.
Vertical
The blades and shaft assembly rotates with respect to the horizontal axis.
Horizontal
Blades are connected and arranged to an open cylinder main shaft.
Open cylinder
Blades are connected and arranged to a closed cylinder main shaft.
Closed cylinder
Machine that is composed of shredding chamber only.
Shredding only
Machine that is composed of shredding chamber (cutting biomass materials into small strips)
and chipping section (cutting twigs or small branches of trees into small and uniform
thickness).
Chipping and shredding
For open cylinder type of shredder, the angle of inclination with respect to horizontal
axis for blades or cutting mechanism attached to the cylinder should ______ be to
facilitate conveyance and to avoid clogging of shredded materials inside the shredding
chamber.
15° to 20°
Clearance between rotating blades and counter blades of the shredding chamber shall
be at least _______.
6 mm (1/4 inch).
Cover for the shredding blades shall be made of at least ______ or its equivalent material to provide safety for the operator during shredding
operation.
2.5 mm MS plate and/or BI
plate
The noise emitted by the biomass shredder shall not be more than ____.
96 dB(A)
Shredding efficiency shall be at least ___.
90%.
distance between the horizontal supporting plane surface and the horizontal plane touching
the uppermost part of the biomass shredder
NOTE: All parts of the biomass shredder projecting upwards are contained between these two planes.
overall height
distance between the vertical planes at the right angles to the median plane of the biomass
shredder and touching its front and rear extremities
NOTE: All parts of the biomass shredder, in particular, components projecting at the front and at the rear are
contained between these two planes. Where an adjustment of components is possible, its shall be set at
minimum length.
overall length
distance between the vertical planes parallel to the median plane of the machine, each plane
touching the outermost point of the biomass shredder on its respective side
NOTE: All parts of the biomass shredder projecting side wards are contained between these two planes.
overall width
running-in period
preliminary operation of the machine to make various adjustments prior to the conduct of the
test until the operation is stable
running-in period
weight of biomass material fed into the shredder, expressed in kilogram per hour
input capacity
biomass material that is not totally cut into strips
unshredded
In general, the test materials shall be ______.
young coconut (“buko)
The amount of
test material to be supplied shall be at least _____ of input capacity of biomass shredder.
75%
For each test trial, weigh three-_____ of biomass materials
100g
