Demystifying the PE 200 x 400 Curseur de mâchoire: Specifications and Applications

The PE (Concasseur primaire) 200 x 400 jaw crusher represents a fundamental workhorse within the realm of mineral processing and aggregate production. Designed for robust primary crushing of hard and abrasive materials, its designation clearly defines its core characteristic: a feed opening measuring 200 mm wide by 400 mm long (environ 8 pouces x 16 pouces). Understanding its specifications is crucial for determining its suitability for specific projects.

Here's a breakdown of the key specifications typically associated with a standard PE 200 x 400 mâchoire mâchoire:

1. Taille de l'ouverture d'alimentation: 200 mm x 400 mm (8" x 16") - This defines the maximum lump size the crusher can accept horizontally and vertically.
2. Taille maximale d'alimentation: Typically ≤ 180 mm (≤ ~7 inches) - The largest piece of material recommended for efficient crushing without causing blockages or excessive wear.
3. Plage d'ouverture de décharge: Adjustable between approximately 20 mm à 80 mm (~0.8" to ~3") - This range determines the final product size after crushing.
4. Capacité: Varies significantly based on:
Dureté du matériau & abrasivité
Distribution de la taille des aliments
Discharge setting
Teneur en humidité
Crusher condition
A realistic throughput range is often 5 à 20 tonnes per hour under optimal conditions for medium-hard materials.
5. Vitesse de l'arbre excentrique: Around 300 tr/min - This rotational speed impacts the crushing action and capacity.
6. Puissance du moteur: Commonly driven by a 15 kW / ~20 HP electric motor (par ex., Y160M-4). Provides sufficient torque for breaking hard rocks.
7. Dimensions (Env.):
Longueur: ~1450 mm (~57")
Largeur: ~1340 mm (~53")
Hauteur: ~860 mm (~34")
(Note: Exact dimensions can vary slightly between manufacturers).
8. Poids: Environ 2800 kilos (~6200 lbs) - Indicates structural robustness but also transportation requirements.
9. Plaques à mâchoires: Constructed from high manganese steel (Mn13Cr2, Mn18Cr2, etc.) for wear resistance against abrasive materials.
