Motor Për Polic Nofulla Pe 250 X 400

PE 250 x 400 jaw crusher stands as a cornerstone in small to medium-scale crushing operations worldwide. Its robust construction, manageable size, and proven effectiveness in handling hard and abrasive materials like granite, bazalt, konkrete, and ore make it indispensable in quarries, vendet e minierave, recycling facilities, and construction projects. Megjithatë, the consistent performance and longevity of this workhorse depend critically on a component often overshadowed by the crusher itself: the electric motor. Selecting the correct motor untuk jaw crusher PE 250 x 400 is not merely a box-ticking exercise; it’s fundamental engineering dictating efficiency, besueshmëria, and operational cost.

Understanding the PE 250 x 400 Workhorse

Before delving into motor specifics, appreciating the crusher's mechanics is crucial:

1. Funksioni kryesor: Utilizes two manganese steel jaws – one fixed and one movable – to compress incoming feed material against the fixed jaw until it fractures.
2. Specifikimet:
Hapja e furnizimit: 250mm (Gjerësia) x 400mm (Gjatësia) - defining maximum lump size (~210mm).
Madhësia maksimale e furnizimit: Approximately ≤210mm.
Gama e hapjes së shkarkimit: Typically adjustable between 20mm to 80mm (settings vary).
Kapaciteti: Highly variable (5-20 ton në orë), dependent on material properties (fortësi, dendësia), shpërndarja e madhësisë së ushqimit, vendosja e shkarkimit (CSS), jaw plate profile (p.sh., corrugated vs. e lëmuar), and overall machine condition.
Shpejtësia e çuditshme e boshtit: Around ~275 RPM (±10 RPM). This rotational speed drives the reciprocating motion of the movable jaw via toggle plates.
3. Cikli i dërrmimit & Load Profile:

The cycle involves an opening stroke (ku hyn materiali) and a closing/power stroke (where crushing occurs).
Load is highly cyclical and shock-intensive. The motor experiences significant peak torque demands during:
Initial acceleration from standstill against inertia.
Crushing tough lumps or encountering non-crushables momentarily ("tramp events").
Overcoming friction in bearings and linkages.
Compressing material during the power stroke.
