Bauxite Waste Crushing&Screening Plant in Montenegro

• Type: Semi-Mobile(mounted on steel structure) 
• Max Feeding Size: 450mm
• Final Output Size: 0-5mm, 5-10mm, 10-15mm, 15-25mm
• Capacity: 150TPH

On Nov 23 of 2005, we received deposit from our customer in Montenegro. They are one of the biggest bauxite company there. There are many bauxite waste for crushing used for back filling, infrastructure, construction use.

They ordered a complete bauxite waste crushing and screening plant, including:

• 1.Grizzly Vibrating Feeder: GZD1100X4200/1 set

• 2.Primary Jaw Crusher: PE750x1060/1 set

• 3.Secondary Multi-cylinder Hydraulic Cone Crusher: HPC200C/1 set

• 4.Tertiary Vertical Shaft Impact Crusher: VSI5X8522/1 set

• 5.Vibrating Screen: 3YZS2160/1 set

• 6.Vibrating Screen: 2YZS1860/1 set

• 7.Magnetic Seperator: RCYD-12

• 8.Belt Conveyors: 10sets/212meters

• 9.Steel Structure
   

It is to crush bauxite waste from 450mm into 5mm, 10mm, 15mm, 25mm at 150tons per hour. We dispatched 2 engineers with 1 English translator for installation guidance in Jan of 2006.

Bauxite waste is one kind of hard stone, whose Mohs’ Hardness Scale is 6-7. So we use multi-cylinder hydraulic cone crusher as secondary one in the plant. And the customer needs more fine sand 0-5mm, we equip a sand making machine in the plant to process part of 15-25mm into minus 5mm. 

The reason why we equip multi-cylinder hydraulic cone crusher as secondary crusher are its features/advantages, which are listed as below:

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.

6.Final aggregates with cubic shape

In our factory, we have normal type VSI series and new type VSI5X series vertical shaft impact crusher for choice. Compared with VSI, new type VSI5X have more advantages as below:

• 1After optimized design, the deep-chamber rotor can make the capacity increased by 30%;

• 2Surrounding plate can be inverted, to improve the material’s utilization and increase the lifespan by more than 48%;

• 3Combined hammer design, only need to replace the wearing part, can reduce the operation cost by over 30%. And the use of vice hammer can prevent damage to the vertical plate after the main hammer worn;

• 4The key components’ material adopt the wear-resistant and high temperature resistant materials of the important industries in the USA;

• 5Rhombus shape impact plate is used to prevent the damage of vertical plate;

• 6The selection of bearing is international brand from Japan, Sweden, America, etc;

• 7The design of optimal launch mouth and smooth curve reduces flow resistance of the materials and increases the throughout capacity greatly;

• 8Dual-use material distribution tray is easy to operate and can make two feeding way changes easily;

• 9Special seal structure in lower part of main shaft guarantees no oil leak even without seal;

• 10Japanese hydraulic opening cover device is originally imported. The cover is moved easily and replacement and inspection of inner part is easy;

• 11The selection of high level protection of the motor with features of high efficiency, low noise, etc. The motor complies with (IEC) International Electrotechnical Commission standard, F class insulation, IP54/55 protection level.
