On Nov 14 of 2013, we received deposit from our customer GUDANG HANDAK in Indonesia. They ordered a complete hard stone crushing and screening plant, including:

• Grizzly Vibrating Feeder: GZD1500X6000/1 set

• Pan Feeder: GZG125-4/2 sets

• Primary European Type Jaw Crusher: PEW1100/1 set

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

• Tertiary Multi-cylinder Hydraulic Cone Crusher: HPT300C/2 sets

• Vibrating Screen: 2YZS1848/2 sets

• Vibrating Screen: 3YZS2460/2 sets

• Vibrating Screen: 2YZS2460/2 sets

• Belt Conveyors: 17sets

• Siemens PLC Control System and Touch Screen+Electrical Control Panel

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

 Their project is located in Tarakan, which starts operation in 2014. It is to crush hard stone from 940mm into 0-5mm, 5-10mm, 10-20mm, 20-30mm. We loaded and shipped these goods in 4x40'FR+23x40'HQ totally.

 For the stone on site is very hard, whose Mohs’ Hardness Scale is 6-7, 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:

• 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.

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.
