The PE1500×1800 jaw crusher is a large-scale compound pendulum coarse crushing machine designed for mining, metallurgy, construction, and other industries. It efficiently crushes various ores and rocks with compressive strengths ≤320MPa. Key specifications include: feed size ≤1200mm, capacity 500-1200 t/h, motor power 280-355 kW, adjustable discharge size 220-350mm, and total weight approximately 140 tons. Featuring a deep cavity dead-zone-free design, it incorporates a hydraulic adjustment system and centralized lubrication, delivering both high crushing efficiency and energy savings. Ideal for the primary stage of sand and gravel production lines, it often operates in conjunction with cone crushers and other equipment.
This equipment employs a compound pendulum motion structure, comprising a frame, eccentric shaft, movable jaw plate, and a safety-equipped toggle plate. Its core working principle involves: the motor driving the pulley to rotate the eccentric shaft, causing the movable jaw plate to move along an elliptical trajectory. Materials are crushed through multiple forces including compression and grinding. Compared to simple pendulum models, the compound pendulum structure offers three key technical advantages: First, the more complex motion trajectory of the movable jaw increases crushing efficiency by 20-30%. Second, its lighter weight and compact design facilitate transportation and installation. Third, the deep-cavity V-shaped design minimizes dead zones, while the hydraulic adjustment mechanism enables rapid discharge opening adjustment. Critical components, including manganese steel alloy jaw plates and integral cast steel bearing housings, ensure high crushing strength and operational stability. Additionally, the wedge-type discharge opening design replaces traditional slide gate structures. Combined with a centralized lubrication system, it significantly reduces maintenance complexity and downtime.
For model selection and maintenance, the PE1500×1800 jaw crusher requires matching motor power and discharge parameters to specific production needs. Routine maintenance focuses on bearing lubrication and jaw plate replacement, while monitoring operating temperatures to ensure they do not exceed 70°C. Its hydraulic overload protection system automatically handles sudden overloads, while the centralized lubrication system effectively reduces friction wear. This equipment is particularly suited for coarse crushing operations in large-scale mining. When paired with cone crushers, it can form an efficient aggregate production line. However, note that feed size must be controlled below 1200mm to prevent equipment overload.

PE1500×1800 Jaw Crusher with 320MPa Crushing Capacity for Coarse Crushing of Ore, Suitable for Multiple Industries Works Principle

The working principle of the PE1500×1800 jaw crusher is based on a compound pendulum motion mechanism. Material crushing is achieved through the periodic squeezing action between the moving jaw and fixed jaw, with the process divided into three distinct stages: As the movable jaw approaches the fixed jaw, the crushing chamber volume decreases, subjecting materials to crushing, bending, and splitting forces; the compound pendulum motion trajectory simultaneously applies compression, grinding, and impact forces to materials, enhancing crushing efficiency; when the movable jaw retracts, the crushing chamber expands, allowing crushed materials to discharge through the outlet under gravity. Forged steel eccentric shaft ensures stable movable jaw motion trajectory, increasing load capacity by 40%. The discharge opening (220-350mm) allows rapid adjustment via the hydraulic system to control final particle size. The symmetrical tooth-shaped liner design extends service life and can be flipped for reuse after wear. This equipment achieves batch production through a continuous cycle of compression and discharge. Its compound pendulum motion trajectory improves crushing efficiency by 20-30% compared to simple pendulum crushers.
