Gold Ore Crushing&Screening Plant in Indonesia

• Type: Semi-Mobile(mounted on steel structure) 
• Max Feeding Size: 700mm
• Final Output Size: 0-20mmmm
• Capacity: 300TPH

On Jan 07 of 2023, we received deposit from our customer Mr.Rafif Adha in Indonesia. They ordered a complete gold ore crushing and screening plant, including:

• 1.Grizzly Vibrating Feeder: F5X1345/1 set

• 2.Pan Feeder: FP1218/2 sets

• 3.Primary European Type Jaw Crusher: PEW860/1 set

• 4.Secondary Single Cylinder Hydraulic Cone Crusher: HST250S2/1 set

• 5.Tertiary Multi-cylinder Hydraulic Cone Crusher: HPT300F1/1 set

• 6.Vibrating Screen: S5X2760-2/1 set

• 7.Belt Conveyors: 6sets

• 8.Electrical Control Panel

• 9.Steel Frame including Chassis, Maintenance Walkway, Hand-grab, Ladder

Their project is located in Kalimantan, which starts operation in 2023. It is to crush gold ore from 700mm into 0-20mm. We loaded and shipped these goods in 1x20'OT+1x40'FR+14x40'HQ totally.

For the stone on site is very hard, whose Mohs’ Hardness Scale is 5.5-6, in this plant, we use single cylinder hydraulic cone crusher as secondary crusher and multi-cylinder hydraulic cone crusher as tertiary crusher, who has more advantages than others:

For single cylinder hydraulic cone crusher:

• 1.Inter-particle crushing works between materials that increase the working life of mantle and bowl liner.

• 2.Provide a more consistent gradation and superior cubic products. Better performance in the construction and sand making field.

• 3.Real-time displays the specification of crushing, hydraulic and lubrication in operation

• 4.It can realize unmanned operation by continuously measuring and automatic setting system.

• 5.Dynamic adjustment of motor power and crusher pressure under working reduces the unnecessary losses made by human error and maximize energy into production.

• 6.The CSS can be adjusted on load.

• 7.The flexible gradation adjustment will save the production cost while increasing the benefits.

• 8.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.

• 9.Constant CSS setting: Once the CSS is set, the output will be kept by continuously measuring and compensating for crusher liner wear.

• 10.The mantle has basic angel between 53°-56°, which will reduce the influence of the capacity due to the moisture content.

• 11.Design with deeper crushing cavity will optimize single cylinder hydraulic cone crusher with more crushing times and higher efficiency.

• 12.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.

• 13.Imported air cooling system avoids the disadvantage of water cooling system, such as lack of water and leakage of water.

• 14.Adoption of international first-class brand controller, such as Winner, Sun, Danfoss, MTS, etc.

 

For multi-cylinder hydraulic cone crusher:

• 1.Unique inter-particle crushing method

Inter-particle crushing works between materials that increases 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 area.

2.Integration of the hydraulic station and lubrication system

Small footprint and easy maintenance;

Save 20% lubrication oil;

Germany AKG air cooling system avoids the disadvantage of water cooling system, such as lack of water and leakage of water;

Larger flow oil pump will guarantee the stability of oil flow;

Temperature sensors keep tracking of the return oil temperature, which will guarantee the stable performance.

• 3.Advanced hydraulic system

Larger diameter tubing and larger capacity hydraulic accumulator improve the stability and response sensitivity;

Hydraulic motor setting adjustment and lock cylinder make it easy to reset the CSS; The hydraulic tramp release cylinders make it easy to pass tramp iron and clean the cavity. Less downtime will cut the maintenance cost.

• 4.Optimized liner retention technology

The thicker liners increase reliability and service life;

Advanced liner retention technology greatly simplifies the liner change. Epoxy resin is not needed, which will cut the manpower and time cost.

• 5.Safe and reliable

Equipped with the Siemens PLC, touch screen, and intelligent control system, operation and data recording is more simple;

Larger bearing area, larger bearing capacity and longer service life;

The overall casting frame with box beam design characterized by larger strength;

The interior of the crusher is protected from dust by the adoption of multiple sealing protection, such as positive pressure dust prevention system, U-T seal and contact-type spherical floating seal.
