A hmasain, a bulpui ber chu hrethiam rawh: drying high-humidity bulk materials pain points.
High humidity: Moisture content is often >30%, 50% thleng pawhin, evaporation load nasa tak a awm.
High Viscosity: Thil hmanrua te chu hmanrua chhung lam bang ah an innghat tlangpui a, chu chuan rulhut leh lump a thlen a, a tawpah chuan hmanrua a chhiat phah thin.
Processing capacity lian tak: A tlangpuiin, hei hian industrial production chhunzawm zel a huam a, single-unit processing capacity sang tak (darkar khata ton za tam tak) a mamawh a ni.
Energy sensitivity: Chutiang tui tam tak evaporating chuan energy chu core cost a ni a, hmanrua thermal efficiency chuan project profitability chu direct-in a tichiang a ni.
Dryers hman tlanglawn tak tak, disc dryers, belt dryers, leh flash dryers te hi heng pain point pakhat emaw a aia tam emaw an hmachhawn hian an hlawhchham fo thin. Rotary kiln dryers, an design danglam tak nen chuan heng pain points te hi hmachhawn turin practically an siam a ni.
II a ni. Rotary Kiln Dryers-a hnathawh dan tur (work principle) a ni.
1. Countercurrent heat exchange: Hei hi an efficiency sang tak bulpui ber a ni. Material chu a chung lam tawp lamah rotary drum chhungah a lut a, high-temperature hot air chu a hnuai lam tawp lamah (discharge end)-ah a lut thung.
A thatna: Flue gas lum ber chuan a lum ber (a lum lutuk tawh, a lum lutuk tur venna) a tawk a, chutih laiin low-temperature, high-Humidity exhaust gas chu tui lum ber (a heat exchange capacity la awm chu hman a nih theih nan) a tling a ni. He model hian a kalphung zawng zawngah heat transfer driving force a tipung a, chu chuan heat utilization sang tak a thlen a ni.
2. Rotation leh Lifting: Drum chu slope engemaw takah (a tlangpuiin 3{4}5%) leh speed-ah zawi zawiin a inher a. Drum chhung lam bang chungah lifting plate chi hrang hrang dah a ni. Anni hian hmun pawimawh tak an chang a: rotation chhung hian material chu an han chawi sang zel a, chutah chuan angle bik hmangin an thlak a, drum cross-section pumpuiah material uniform curtain an siam a ni.
Hlawkna: Hei hian thil leh boruak lum inkar contact area nasa takin a tipung a, boruak lum chuan material layer chhungah a lut thei a, chu chuan heat exchange nasa tak leh tha tak a thlen thei a ni. Sticky materials clumping leh wall-a innghat chungchanga harsatna pawimawh tak takte chu a chinfelsak tha hle.
3. Collaborative Operation: Lifting plate-te chuan a khalh a, chu thil chu a chungah a han chawi a, a darh zel a, chutih lai chuan gravity leh drum inclination avang chuan a hnuai lam pan chuan zawi zawiin a kal a. A tawpah chuan dry material chu a hnuai lam atang chuan a chhuak a, exhaust gas chu a chung lam atang chuan a chhuak ta a ni.
A awlsam zawngin, a "rotation" chuan a continuous, "cascade-like" rain of material a siam a, chu chuan boruak lum chu a lut tha thei a, moisture a paih chhuak thei a ni.
iii a ni. Structural advantages: Dimension pangaa sak "moat" a ni.
1. Throughput .
Drum lian tak (meter zau zawng leh a sei zawng meter sawm vel) hian a pianphungah chuan processing capacity nasa tak a pe a, awlsam takin tunlai industry-in a mamawh economies of scale chu a hmu thei a ni.
2. Material adaptability .
3. Rinnawm .
Power system hian a bul berah chuan classic roller + roller drive system a hmang a, chu chu technology puitling tak, rintlakna sang tak nei, thla tam tak chhunga 24/7 continuous leh stable operation nei thei a ni.
Operation a awlsam a, technical skills tlemte chauh a ngai. Operating parameters (speed, inclination angle, air temperature, leh air volume) an set hnuah chuan product moisture content chu mak tak maiin a la nghet reng a ni.
4. thermal efficiency .
Countercurrent process leh heat exchange area lian tak nena inzawm chuan thermal efficiency chu a tlangpuiin 60%-75% vel a thleng thei a, hei hi traditional dryers tam tak aiin a sang zawk hle. Hei hian fuel cost a tihhniam phah a ni.
Heat source hrang hrangah a insiamrem thei hle a, flue gas, steam leh thil dang tam tak a hmang thei bawk.
5. Nunna leh a chhe thei lo .
Heavy-duty steel structure leh wear-resistant materials (wear-resistant steel plates emaw castables emaw ang chi) te hian kum 20 chuang zet design lifespan a enkawl a, hei hian one- hun rei tak chhunga hlawkna a neih theihna tur a tichiang a ni.
