Product Overview
The CRUSTION CMK series coarse crushing gyratory crusher is a next-generation primary crushing equipment newly developed for ultra-large mines and quarry projects. It enables continuous primary crushing operations and features high throughput and excellent crushing performance. It adopts an alloy cast steel heavy-duty frame, an alloy-forged integral body shaft, arc-shaped gear transmission, and hydraulic adjustment of the discharge opening, making it widely applicable to the primary crushing of various minerals and rocks in mining, hydropower, metallurgy, construction, and other fields.

Working principle
The motor drives the crusher’s horizontal shaft via a coupling, V-belt, and pulleys.
A high-precision spiral bevel gear with helical teeth (offering advantages such as high transmission stability, strong load-carrying capacity, large transmission ratio, smooth operation, and low noise) is mounted on the horizontal shaft; the meshing pinion and gear drive the eccentric sleeve assembly to rotate.
The eccentric sleeve, featuring an eccentric inner cylindrical surface, forces the moving cone (the crushing part) to perform a swinging motion, thereby generating periodic relative motion between the eccentrically oscillating moving mantle and the stationary fixed mantle.
After the material enters the crushing chamber—formed by the moving and stationary cone liners that oscillate periodically in a cyclical motion—through the top feed hopper, it is subjected to compressive and bending forces, thereby achieving size reduction.
The crushed material is discharged from the machine by gravity through the circumferential cavity of the lower frame.
Product Features
1. Deep-cavity crushing chamber
Its unique deep-V-shaped crushing chamber and extended feed opening ensure a larger inlet size, allowing material to pass through the crushing chamber more smoothly for continuous operation. This design delivers high throughput, excellent crushing efficiency, uniform product particle size, reduced liner wear, and low operating costs.
2. High degree of automation
The spindle positioning control system allows for easy adjustment of the spindle to compensate for liner wear and control product particle size.
3. Balance Cylinder System
The balance cylinder system prevents spindle runout; in the event of overload, the spindle automatically lowers, mitigating impact from spindle vibration when oversized material enters the equipment and ensuring safe, stable operation.
4. Positive Pressure Dust Control System
Equipped with a positive-pressure dust-proof system, it effectively prevents dust from entering the equipment’s eccentric and transmission mechanisms, avoids contamination of the lubricating oil, and extends the service life of the entire machine.
