The special moving jaw of the jaw crusher is the core transmission and crushing part of the equipment. It is adapted to the jaw crusher and installed in the core position of the crushing cavity. It squeezes the material through reciprocating movement to realise material crushing. It is a key accessory to ensure the normal operation of the equipment.
Our comprehensive range of crushing, screening, and conveying equipment is widely utilized in mining, metallurgy, construction materials, highway and railway infrastructure, water conservancy, and the chemical industry. We provide complete production line solutions tailored to specific geological and operational requirements.
Yes. With over 30 years of experience in steel casting, we offer more than 10,000 types of wear-resistant castings, including jaw plates, mantle/concave sets, and blow bars. We support OEM/ODM services based on your technical drawings or specific material requirements (High Manganese Steel, Chrome, etc.).
While both are designed for primary crushing, the JC Series features a more advanced modular, non-welded frame structure for higher fatigue resistance and easier maintenance. The PE/PEX Series is our classic, high-performance solution known for its robust reliability and cost-effectiveness in processing hard ores.
For sand making and shaping, we recommend our VSI Vertical Shaft Impact Crusher or the YB Series Double Roller Sand Maker. These machines are engineered to provide excellent cubic particle shapes and precise grading, which are essential for high-grade concrete and asphalt production.
Our HPT and HC Series Cone Crushers utilize high-strength alloy castings and optimized hydraulic systems. These features allow for high crushing force and high-frequency strokes, ensuring efficient throughput even when processing abrasive materials like basalt or granite.
Material selection depends on the feed size and hardness. For high-impact primary crushing (Jaw Crushers), we typically use High Manganese Steel (Mn13, Mn18, Mn22). For high-abrasion environments (VSI or Impact Crushers), we offer High-Chrome Castings and specialized alloys to maximize the service life of your components.
Key inspection points include:
Checking the lubrication system and bearing temperatures.
Ensuring the tension of the V-belt is correct.
Verifying that all bolts and fasteners are secured.
Observing the stability of the flywheel and counterweights for any unusual vibration or noise.
Lead times vary by project scale. Standard single machines (like feeders or conveyors) typically ship within 15-30 days, while custom-engineered production lines may take 45-60 days to allow for comprehensive design and pre-assembly testing.
