4.原材料的品質(zhì)要求Requirement of Raw Materials Quality
原材料會(huì)直接影響顆粒的成型,對(duì)設(shè)備的產(chǎn)量以及設(shè)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(jīng)過(guò)去鐵處理,保證進(jìn)入ZLP系列造粒機(jī)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(jìn)行篩分處理,保證進(jìn)入造粒機(jī)的原材料顆粒在4mm以內(nèi)。
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(guò)日曬或烘乾處理,保證進(jìn)入造粒機(jī)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(zhì)原材有時(shí)不易成型或產(chǎn)量偏低,適當(dāng)混合其他的木質(zhì)原料可有較提
高顆粒的產(chǎn)量及顆粒品質(zhì)。
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(méi)有市場(chǎng)。
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(dāng)提高原材料的溫度,當(dāng)溫度達(dá)到或超過(guò)80℃時(shí),木質(zhì)纖維軟化,可有效提高
顆粒的成型品質(zhì)和產(chǎn)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(jī)供料時(shí)必須勻速給料,不能時(shí)快時(shí)慢,太快時(shí)容易造成悶
機(jī)(停機(jī)),太慢時(shí)又會(huì)影響產(chǎn)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(chǎn)量品質(zhì)。
Raw materials need homogenizing
treatment,ensure the uniformity of raw material
moisture and
temperature.
