Performance Characteristics:

1. Simple structure, smooth operation, stable performance and leading output among similar products;

2. A machine frame, which adopts CO2 protection welding and is subjected to annealing treatment, is tight and durable;

3. High manganese steel protection is adopted for all easily worn parts, so that the service life is prolonged;

4. A spring locking device can provide stable crushing force and excessive iron release protection;

5. A hydraulic clean cavity oil cylinder can quickly remove aggregates and difficultly crushed materials in a crushing cavity, so that the maintenance time is greatly shortened;

6. A material-discharging port is hydraulically adjusted, so that the adjustment is convenient, quick and accurate;

7. A labyrinth type dustproof ring is used for sealing to ensure clean lubricating oil;

8. The mounting faces of moving and static gear plates both are subjected to finish machining, and fillers are not used, so that their replacements are convenient and quick;

9. A lubricating system is provided with an oil return and temperature protection device, and interlocked with a main motor, so that the main motor is protected from damage.
