4.原材料的品質要求Requirement of Raw Materials Quality
原材料會直接影響顆粒的成型，對設備的產量以及設備的使用壽命影響很大。
Raw materials will directly affect the
pellets forming, greatly influence the
equipments output and useful life.
4.1去鐵De-ironing
原材料必須經過去鐵處理，保證進入ZLP系列造粒機的原材料不能有螺栓、
螺母、鐵釘、鐵塊等金屬異物和石塊、水泥塊。
Raw materials must
go through the de-ironing processing to ensure that
materials entering into ZLP series
granulator without bolts, nuts, nails,
iron and other metal foreign body and
rock, concrete.
4.2篩分Screening
原材料必須進行篩分處理，保證進入造粒機的原材料顆粒在4mm以內。
Raw
materials must go through screening process to ensure raw materials into
the granulator diameter within4
mm.
4.3含水率Moisture Content
原材料必須通過日曬或烘乾處理，保證進入造粒機的原材料含水率在8%～14%，
太幹或太濕都不利於顆粒成型。
Raw
materials must go through the sun or drying process to guarantee the
moisture of raw materials which enter into the granulator is 8% ~ 14%,
Too dry
or too wet is not good for pellets forming.
4.4混合Mixing
單一的木質原材有時不易成型或產量偏低，適當混合其他的木質原料可有較提
高顆粒的產量及顆粒品質。
A single wood raw materials sometimes are not
easy to form or low yield,
through appropriate mixing some other wooden
raw materials can increase pellets
yield and pellets quality.
4.5熱值Heating Value
顆粒的熱值是由原材決定的，原材料的熱值必須在3500kcal/kg以上。
否則由於熱值太低沒有市場。
Heating
value of the pellets is determined by the raw materials, the heating value
of raw materials must be above 3500 kcal/kg. Otherwise the pellets will
be
without market due to the low
heating value.
4.6溫度Temperature
適當提高原材料的溫度，當溫度達到或超過80℃時，木質纖維軟化，可有效提高
顆粒的成型品質和產量，降低能耗。
We can appropriately to raise the raw materials temperature, when the
temperature reach or exceed80℃, wood fiber softening, it can effectively
improve
the pellets forming quality and
yield, and reduce energy consumption.
4.7勻速給料Uniform feeding
給ZLP系列平模造粒機供料時必須勻速給料，不能時快時慢，太快時容易造成悶
機（停機），太慢時又會影響產量。
It must be uniform
feeding, not be fast in slow when giving ZLP series
flat die granulator feeding. To be fast
is easy to cause stuffy car (stop).
To be slow may affect the production.
4.8勻化處理Homogenizing treatment
原材料要均化處理，保證原料水分及溫度的均勻性，可提高顆粒的產量品質。
Raw materials need homogenizing
treatment,ensure the uniformity of raw material
moisture and
temperature.
