The Liming PE-600×900 Jaw Crusher: A Robust Workhorse for Primary Crushing
In the demanding world of aggregate production, mining, and construction recycling, primary crushing forms the critical first step in reducing large raw materials into manageable sizes. Among the diverse range of jaw crushers available globally, the Liming PE-600×900 Jaw Crusher, manufactured by Henan Liming Heavy Industry Science & Technology Co., Ltd. (often referred to as Liming Heavy Industry), stands out as a highly capable and widely utilized machine designed for reliable medium-to-large scale operations.
Understanding the Model: PE-600×900
The designation itself reveals key specifications:
PE: Stands for “Primary Crusher,” indicating its core function within a crushing circuit.
600×900: Refers directly to the dimensions of the feed opening – 600 mm wide by 900 mm long (approximately 24 inches x 35 inches). This size dictates the maximum lump size of material it can accept comfortably (typically up to around 500 mm or less).
Core Specifications & Capabilities
The PE-600×900 is engineered for performance:
Feed Opening: 600 x 900 mm (24″ x 35″)
Max Feed Size: Up to ~500 mm (20″) (dependent on material characteristics)
Discharge Opening Range: Adjustable within a typical range of approximately 65-160 mm (2.5″ – 6.3″). This adjustability allows operators flexibility in achieving different final product sizes.
Capacity: A significant factor driving its popularity is its robust throughput capacity, generally ranging between 50 – 180 tonnes per hour (55 – 200 US tons per hour). Actual output depends heavily on:
Material hardness and abrasiveness (e.g., granite vs limestone).
Feed size distribution.
Desired product size setting.
Moisture content.
Drive Power: Typically powered by an electric motor in the range of 55 – 75 kW (75 – 100 HP), providing ample force for effective crushing.
Weight: The substantial frame contributes to stability; expect an operating weight around 15-17 tonnes (16.5 – 18.7 US tons).
Components:
Robust welded steel frame for high rigidity under load.
High-quality cast steel swing
