I. Conveyor arung arai ni a bungli galaw ai shara
Conveyor jak ni gaw, matut manoi (sh) aten kadun laman galaw ai arung arai ni hpe lu la na matu, jak rung atsam hpe jai lang ai. Shi a bungli galaw ai npawt tara hpe ahkyak ai lahkam masum hku garan mai ai:
. Ga shadawn, belt conveyor ni a matu motor power range gaw 0.5 kaw nna 200 kW du hkra (GB/T 10595-2017 hpe yu u), n-gun dat n-gun hte n-gun n-gun hta hkan nna manu dan ai.
. Ga shadawn, screw conveyor ni hta, blade a lawan ai lam hpe 20 hte 60 rpm lapran hta hkang ra ai. Grai lawan ai gaw, arung arai ni hpe hkra machyi shangun nna, n-gun grai yawm ai gaw, n-gun hpe hkra machyi shangun chye ai.
3. Directional Control: Hkrun lam hkawm ai lam hpe roller ni, lam madun ai lam ni, shing nrai, npawt nhpang ni hpe woi awn ai lam ni hku nna lam madun ai. Chain conveyor ni gaw meshing gears hte chain ni hpe jai lang nna, dingyang shamu shamawt ai lam hte tilt angles ni hpe 45℃du hkra lu la ai (ISO 1977:2006).
II. Mainstream Types ni a hpaji masa n bung ai lam ni hte jai lang ai lam ni
1. Belt Conveyor
- Principle: N htum n wai ai rubber belt gaw drive roller hte bend roller lapran hta hkawm sa wa nna, dai gaw belt makau hku hkawm sa wa ai, n-gun n-gun n-gun n-gun n-gun n-gun n-gun hte.
- Shada da ai lam ni: Galu sin a matu galu kaba ai- a matu hkan sa mai ai (data langai a matu 15 km du hkra), n-gun n law ai- hta n-gun n law ai arung arai ni hpe htaw sa ai lam, 30%-40% shayawm ai n-gun dat jai lang ai lam ni hpe chain conveyer ni hta grau nna.
- Ga shadawn: 800-2000 mm galu ai steel cord conveyor belt ni hpe nhprang wan htu ai bungli hta law law lang lang ai, 3150 N/mm2 ngu ai n-gun n-gun n-gun n-gun hte n-gun n-gun n-gun n-gun n-nga ai.
2. Screw Conveyor
- Principle: N-gup magap ni hpe galai shai ai gaw, n-gup magap hpe pat da ai hka htung makau kaw axially propel galaw ai. Powdery (sh) granular arung arai ni a matu htuk manu ai.
{0}} Ahkyak ai Parameters: Hka ja ai lam gaw 40% hta grau ai (sh) maren sha rai ra ai, n rai yang clogging galaw na zawn rai nga ai. Dai htawn tsun ai atsam hpe sawn la ai ladat gaw Q {{3}D.D2nψρ (D gaw diameter, n gaw shinggrup ai lawan ai, ψ gaw fill factor, ρ gaw material density re).
3. Pneumatic Conveying System
{0}} Principle: Nbung lwi ai n-gun hpe jai lang nna, arung arai ni hpe jahkring kau nna, n-gun jaw ai. Dai gaw, n-gun lahkawng hku nna bungli galaw ai: dilute phase (nbung n-gun > 18 m/s) hte n-gun ja ai daw (nbung n-gun < 10 m/s).
- N-gun jaw ai lam shingdaw ai lam: Dense phase gaw, arung arai ton mi hta 5-8 kWh daram sha ai, dilute daw (American Pneumatic Conveying Association hte maren) hte shingdaw yang, 20% jan hpe hkye la lu ai.
III. Akyu rawng ai lam hpe grau kaja hkra galaw ai hte manghkang byin shangun ai
1. N-gun atsam hparan ai lam: Conveyor belt tension hpe 1%{6}}2% galu kaba ai hku gram lajang ra ai. Overtighting gaw 10%-15% hte motor load hpe jat ya ai, grai law hkra loose galaw ai gaw slippage byin shangun ai.
. Chain jak ni hta, shingkyit bu hpun na matu shata shagu jep joi ra ai; chain bu hpun ai 3mm jan ra ai.
