The  large crushing ratio machinery

Application

1.Crushing machinery is mainly used in metallurgy, mining, chemical, cement, construction, refractory and ceramic industries such as cutting medium hard ores and rocks into coarse ,medium and fine crushing

2.Jaw crushers are best for crushing a variety of soft and hard ore , the compressive strength of which is less than 300MPa (MPA) . The maximum size of .crushed material can not be larger than stipulated in the technicalparameters

The operatingprinciple of Crushing machinery 

The working style of these series jaw crusher is curved dynamic extrusion.

Its work principle :

Motor drive belt and pulleyto make moving jaw up-and-downmotionthrough eccentricspindle.

When moving jaw rise, the angle between toggle plate and movingjaw gets bigger to push the movablejawplatecloseto the fixed jaw plate, so that the materialsarecrushedorchoppedinto small pieces

When moving jaw goes down, moving jaw pull rod under the action of the spring to make it leaving the fixed jaw plate, then the crushed material is discharged from the crushing chamber mouth under gravity.

Crushing machinery features:

(1) Deepcrushingchamberandnodeadzone

improving feed capacity and yield;

(2) the large crushing ratio, uniform product size;

(3) the gasket type of discharge adjustment device:reliable andconvenient, largeadjustmentrange, increasing the flexibility of the equipment;

(4) the lubrication system is safe and reliable, easy parts replacement, maintenancesmallworkload

(5) simple structure, reliable performance, low operating costs;

(6) energy-saving equipment: single energy saving 15%~30% system energy-saving more than 1 time;

(7) large range of discharge opening adjustment to meet different user requirements;

(8) low noise, less dust.
