Primary Crushing Equipment
A robust primary crusher engineered for reducing hard ores and rocks with compressive strength below 320 MPa. Featuring PE and PEX series with feeding sizes from 125mm to 1200mm and capacities from 1 to 1,200 t/h — the workhorse of cement plants, mines, and quarries worldwide.
Product Overview
The jaw crusher is a primary crushing machine that uses compressive force to break down large blocks of raw material. Two jaw plates — one fixed and one movable — form a V-shaped crushing chamber. As the movable jaw swings toward the fixed jaw, material is compressed, fractured, and reduced in size. When the jaw retracts, the crushed material discharges through the bottom opening by gravity.
In cement production lines, the jaw crusher is typically the first stage of the comminution process, reducing quarried limestone, marl, shale, and boulders to a manageable size for downstream secondary and tertiary crushers. LIMING Machinery manufactures both PE series (coarse primary crushing) and PEX series (fine/secondary crushing) jaw crushers, with over 20 models covering the full capacity range from small -scale plants to 10,000-TPD cement lines.
Built with high-strength cast-steel frames, premium manganese steel jaw plates, and oversized spherical roller bearings, LIMING jaw crushers deliver decades of reliable service in the most demanding quarry and cement-plant environments. The deep crushing chamber design ensures high reduction ratios, uniform discharge granularity, and minimal slabby product.
Classification
Jaw crushers are classified by their crushing-chamber motion mechanism and by their application. LIMING supplies both main motion types and both primary/fine series.
Uses two toggles and a pitman to transmit crushing force. The movable jaw moves vertically as well as horizontally, producing a rubbing/rolling action that reduces wear and produces more uniform product. Suitable for hard, abrasive materials.
Uses a single toggle and an eccentric shaft. The movable jaw performs an elliptical motion with both compressive and rubbing actions. Fewer moving parts, lighter weight, lower cost — the most common type in modern cement plants and quarries.
Coarse crushing models with large feed openings (150×250 to 1500×1800). Accepts run-of-mine material directly from the quarry. Used as the first-stage crusher in cement plants, mining, and aggregate production.
Narrower discharge opening for secondary or fine crushing. Produces smaller, more uniform discharge (8-90mm). Often installed after a PE-series primary jaw crusher or as a standalone fine crusher for smaller operations.
Key Benefits
Engineered for maximum uptime and lowest operating cost in continuous-duty cement and mining operations.
High-strength cast-steel frame and heavy-duty eccentric shaft withstand the toughest crushing loads. Designed for 24/7 continuous operation in cement plants and large-scale mines.
Premium manganese-steel jaw plates (Mn13/Mn18) handle materials up to 320 MPa compressive strength. Deep crushing chamber increases reduction ratio and throughput.
Hydraulic or wedge discharge-opening adjustment lets operators change product size quickly and safely — without dismantling the machine or risking injury.
Oversized spherical roller bearings and optimized kinematics deliver high load-carrying capacity, stable operation, and extended bearing service life even under shock loads.

How It Works
The jaw crusher operates on the principle of compressive crushing. An electric motor drives the eccentric shaft via V-belts and a flywheel, causing the movable jaw to swing in a controlled elliptical motion against the fixed jaw. Here is the step-by-step process:
