EPC general contract construction, production of washed-sand, concrete and other building materials, but also installed the Zhongyu Dingli intelligent mine management system, to achieve more convenient production line management and operation.

The project is located in China, put into operation in 2019, mainly processing limestone, the design output of 3000t/h, the annual output of 10 million tons, the production of 0-5, 1-2, 1-3 and other specifications of stone, the total investment of the project is 21069191.2240 US dollars.

It’s seen the gravel aggregate production line has large scale which can meet the customer requirement for large capacity. The dust collectors will be configured later for environment protection.
The CJ409 Jaw crushers have played a pivotal role in the mining and construction industries for over a century. Their design has evolved significantly, incorporating new technologies to improve efficiency and performance.
The earliest jaw crushers were simple, manually operated machines that used mechanical pressure to break down stones. These early models were effective but lacked the efficiency of modern designs.
Hydraulics: The introduction of hydraulic systems allowed for easier adjustment of the discharge opening and provided overload protection, making CJ409 jaw crushers safer and more efficient.
Wear-Resistant Materials: Advances in metallurgy have led to the development of more durable jaw plates and other components, reducing the need for frequent replacements and lowering operational costs.
Automation: Modern jaw crushers often feature automated control systems that optimize performance by monitoring the crusher's operation and making real-time adjustments.
As industries continue to demand more from their crushing equipment, future developments in jaw crusher technology may focus on further enhancing energy efficiency, reducing environmental impact, and improving automation capabilities.
