Application
BREAK-DAY specializes in producing jaw crusher which is widely used in mining, quarry, material handling. Our company has been a manufacturer and exporter of crushers for decades.
We have various models of jaw crusher. The structure of jaw crusher includes mainframe, main axle, roller bearings, eccentric shaft, jaw plates, side plates, toggle mechanism, fly wheels and springs.
The jaw crusher is ideally suitable for primary and secondary crushing with low power consumption and easy maintenance. Every feature of this machine has been carefully designed to provide superior quality and performance. It is widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc. It is recommended by leading consultants in this field and is used by hundreds of customers all over the world.
Features:
It is of various types.
It is suitable for crushing maximum, medium and minimum stones.
The operating principle is easy to be operated.
Its structure is simple and it is easy to maintain.
Functional Process:
Load the material for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings outward and presses closely upon the ring. The shovel carries the material to the space between the roller and ring. When the roller rolls, the material is thus ground.
After being ground, the material is to be routed to the sorter along the wind belt of the blower and the coarse powder will be put back to the mill for regrinding. The fine powder flows into the cyclone collector together with airflow and is expelled from the discharge pipe as final product.
In the grinding chamber, since the material may contain moisture to some extent, the heat generated during grinding makes the moisture evaporated; since the pipeline joints are not airtight, the external air is sucked in and the circulation air amount increases. In order to enable the mill to work under negative pressure, the increased airflow is guided to the deduster anew sequentially to the atmosphere after purification.
