CMK Series Coarse Gyratory Crusher

The CMK series coarse gyratory crusher is a primary crushing solution built for ultra-large-scale mining and quarrying operations. It is available in six models: CMK4265, CMK5065, CMK5475, CMK6275, CMK6089, and CMK60110. These models cover a maximum recommended power range of 400 kW to 1000 kW, a maximum feed particle size of 950 mm to 1350 mm, and a loose edge discharge port size (OSS) from 140 mm to 250 mm. Processing capacity varies by model and setting, ranging from 2010 t/h to 8890 t/h. The crusher incorporates a heavy-duty alloy cast steel frame, an alloy forged integral body shaft, arc gear transmission, and a hydraulically adjustable discharge port, ensuring reliable performance in demanding primary crushing applications.

The CMK Series is engineered for continuous primary crushing in mining, hydropower, metallurgy, and construction industries. Its deep V-shaped crushing chamber and long feed inlet design allow smoother material flow, enabling continuous crushing with large processing capacity, high crushing efficiency, uniform finished product particle size, and reduced liner wear. The highly automated spindle positioning control system easily adjusts the spindle to compensate for liner wear and control product particle size. The balance cylinder system prevents the main shaft from running out of space and allows automatic descent under overload conditions, protecting the equipment when oversized materials enter the chamber. The positive pressure dust control system prevents dust from entering the eccentric and transmission devices, avoiding lubricating oil contamination and extending the service life of the whole machine.

Compared to other crushers in the series, each CMK model offers distinct capacity and feed size advantages. The CMK4265, with 400 kW power and 950 mm max feed size, delivers 2010–2870 t/h, making it suitable for medium-scale operations. The CMK60110, with 1000 kW power and 1300 mm max feed size, achieves 5535–8890 t/h, ideal for the largest mining projects. The CMK5475 and CMK6275 bridge the gap with 450–500 kW power and 1180–1350 mm feed sizes. This range allows precise selection based on throughput requirements and feed material characteristics, ensuring optimal performance and cost efficiency.
