250x400 Jaw Crusher for Primary Crushing of Ores and Bulk Materials

Product Overview

Engineered for medium to coarse crushing of ores, minerals, and bulk materials, this jaw crusher delivers exceptional performance in demanding production environments. Its curved jaw plate profile and eccentric drive mechanism generate combined compressive, shear, and attrition forces that efficiently reduce feed material. The innovative deep crushing chamber not only maximizes throughput by eliminating dead zones but also ensures uniform product sizing, a critical factor in downstream processing.

Serving as a primary crusher, the unit is ideally suited for mining operations, quarrying, cement plants, and industrial mineral processing. It reliably handles rocks such as granite, basalt, iron ore, copper ore, and limestone, as well as construction demolition waste. With a maximum feed size of 210 mm and throughput ranging from 5 to 16 tons per hour, it meets the needs of mid-scale production lines and pilot plants alike. The adjustable discharge aperture, ranging from 20 mm to 80 mm, provides the flexibility to target specific gradations for different end uses.

Constructed from heavy-duty steel plate and equipped with reversible high-manganese jaw plates, this crusher withstands the constant impact and abrasion intrinsic to harsh crushing applications. A centralized lubrication system and strategically placed access points simplify routine maintenance, drastically reducing downtime. The robust design, paired with an energy-efficient drive system that cuts power consumption by up to 30%, results in a low total cost of ownership and a rapid return on investment. As part of a complete sample preparation line, this crusher integrates seamlessly with our other powder processing equipment, offering a comprehensive solution for material science laboratories and pilot plants.

Key Features

• Deep Crushing Chamber with Optimized Geometry: The uniquely designed chamber is free of dead zones, which dramatically boosts feed intake capacity. This geometry allows larger volumes of material to enter and pass through without bridging, increasing production rates. As a result, the crusher achieves higher throughput with fewer blockages compared to conventional designs.
• High Reduction Ratio: Achieving a substantial size reduction in a single pass, this unit minimizes the requirement for secondary and tertiary crushing stages. This simplifies plant layout, lowers capital expenditure on additional machinery, and reduces the overall energy consumption of the comminution circuit. The high ratio is particularly advantageous when processing hard, dense materials.
• Adjustable Discharge Opening: A reliable shim-type gap adjustment system provides precise control over product particle size from 20 mm to 80 mm. Operators can quickly modify the setting to meet varying specifications without interrupting production. This flexibility allows the same crusher to serve different processes, from coarse aggregate to fine feed preparation.
• Heavy-Duty Construction: The frame is fabricated from reinforced steel plates, and critical components like the eccentric shaft and bearings are oversized for durability. This rugged build ensures stable operation under peak loads and extends the service life of the equipment. Even under continuous, high-impact conditions, the crusher maintains alignment and structural integrity.
• High Manganese Steel Jaw Plates: The wear-resistant manganese steel castings are provided as standard, offering exceptional longevity. Their high work-hardening capacity provides superior abrasion and impact resistance, significantly reducing the frequency of wear part replacement. The plates are reversible, doubling their useful life before replacement is needed.
• Energy-Efficient Drive System: An optimized drive train, including a large flywheel and efficient motor, reduces peak power demands and achieves energy savings of up to 30% compared to many traditional designs. This translates directly into lower electricity costs per ton of material crushed. The flywheel also helps smooth out fluctuations, ensuring stable operation.
• Low Environmental Impact: Sealed bearing housings and precision-machined mating parts minimize dust leakage, while the balanced rotor design limits vibration and noise generation. This fosters a cleaner, quieter, and safer working environment, exceeding occupational health standards in many regions.
• Simplified Maintenance: Easily accessible bolt-on wear plates, side liners, and toggle plate allow rapid replacement by a single technician. A centralized grease lubrication system ensures all pivot points receive consistent lubrication with minimal manual intervention. This reduces planned maintenance time and improves overall availability.
• Integrated Overload Protection: The toggle plate serves as a mechanical fuse, shearing when unbreakable objects enter the chamber. This protects the frame and bearings from catastrophic damage, saving costly repairs and downtime.
• Reliable Jaw Return Mechanism: Heavy-duty tension springs and rods ensure the swing jaw returns positively after each crushing cycle, maintaining a consistent crushing stroke and preventing material clogging.
