On August 09 of 2021, we received deposit from our customer in Tỉnh Quảng Ninh, Vietnam. They ordered a complete limestone crushing and screening plant, including:

Grizzly Vibrating Feeder: F5X1560H/1 set
Pan Feeder: SP0816/2 sets
Primary Jaw Crusher: PE900X1200/1 set
Secondary Single Cylinder Hydraulic Cone Crusher: HST315/1 set
Vertical Shaft Impact Crusher: VSI5X1145/1 set
Vibrating Screen: 3YK3X3075/1 set
Vibrating Screen: 2YK3X3075/1 set
Vibrating Screen: 2YZS2160/1 set
Belt Conveyors: 13sets
Steel Structure: 1lot

We loaded and shipped these goods in 2x20'OT+3x40'FR+10x40'HQ totally.

Their project is located in Tỉnh Quảng Ninh. It is to crush limestone from 750mm into 0-1/4”, 1/4”-3/8”, 3/8”-3/4”, 3/4”-1 1/2”. Because there is big demand for fine sand 0-5mm on the market, they purchase a separate sand making machine(vertical shaft impact crusher) VSI5X1145 to process part of 3/4”-1 1/2” into 0-5mm.

In this plant, we use single cylinder hydraulic cone crusher as secondary crusher, who has more advantages than others:

Inter-particle crushing works between materials that increase the working life of mantle and bowl liner.
Provide a more consistent gradation and superior cubic products. Better performance in the construction and sand making field.
Real-time displays the specification of crushing, hydraulic and lubrication in operation
It can realize unmanned operation by continuously measuring and automatic setting system.
Dynamic adjustment of motor power and crusher pressure under working reduces the unnecessary losses made by human error and maximize energy into production.
The CSS can be adjusted on load.
The flexible gradation adjustment will save the production cost while increasing the benefits.
Constant load setting: The CSS will be adjusted automatically according to the changes of the feeding size, moisture and hardness of the material and make sure the load of the crusher is constant.
Constant CSS setting: Once the CSS is set, the output will be kept by continuously measuring and compensating for crusher liner wear.
The mantle has basic angel between 53°-56°, which will reduce the influence of the capacity due to the moisture content.
Design with deeper crushing cavity will optimize single cylinder hydraulic cone crusher with more crushing times and higher efficiency.
Hydraulic system: The design pressure of the sealing elements is 20MPA, the maximum working pressure is 4MPA. Pressure margin produced by the higher pressure improves the reliability of operation.
Imported air cooling system avoids the disadvantage of water cooling system, such as lack of water and leakage of water.
Adoption of international first-class brand controller, such as Winner, Sun, Danfoss, MTS, etc.
