Demystifying the PE 200 x 400 Jaw Crusher: Specifications and Applications
The PE (Primary Crusher) 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 (approximately 8 inches x 16 inches). 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 jaw crusher:
1. Feed Opening Size: 200 mm x 400 mm (8″ x 16″) – This defines the maximum lump size the crusher can accept horizontally and vertically.
2. Max Feed Size: Typically ≤ 180 mm (≤ ~7 inches) – The largest piece of material recommended for efficient crushing without causing blockages or excessive wear.
3. Discharge Opening Range: Adjustable between approximately 20 mm to 80 mm (~0.8″ to ~3″) – This range determines the final product size after crushing.
4. Capacity: Varies significantly based on:
Material hardness & abrasiveness
Feed size distribution
Discharge setting
Moisture content
Crusher condition
A realistic throughput range is often 5 to 20 tonnes per hour under optimal conditions for medium-hard materials.
5. Eccentric Shaft Speed: Around 300 rpm – This rotational speed impacts the crushing action and capacity.
6. Motor Power: Commonly driven by a 15 kW / ~20 HP electric motor (e.g., Y160M-4). Provides sufficient torque for breaking hard rocks.
7. Dimensions (Approx.):
Length: ~1450 mm (~57″)
Width: ~1340 mm (~53″)
Height: ~860 mm (~34″)
(Note: Exact dimensions can vary slightly between manufacturers).
8. Weight: Approximately 2800 kg (~6200 lbs) – Indicates structural robustness but also transportation requirements.
9. Jaw Plates: Constructed from high manganese steel (Mn13Cr2, Mn18Cr2, etc.) for wear resistance against abrasive materials.
