Stone crushing line is widely used in stone quarrying, aggregate production, road construction, building, the stone crushing plant also plays an important role in ore minerals beneficiation. The following is some information about stone crushing line capital cost.
stone crushing line direct costs
The largest primary gyratory crushers cost US $2 million or more, while overall crushing plant costs can be as high as $18 million. It’s necessary therefore to estimate crusher installation costs based on equipment costs plus the following direct costs, including construction contractor indirects:
• Earthworks
• Mechanical
• Concrete
• Electrical
• Structural steel
• Instrumentation.
• Architectural
stone crushing line indirect costs
Indirect costs can fall within a range of 40 to 60% of the direct costs, and
include:
• Construction indirects
• Startup and commissioning
• Construction equipment
• Freight
• Spare parts/first fill
• Taxes/duties
• Engineering, procurement and construction management (EPCM)
• Owner’s costs (relocation, hiring and training personnel, permits, licensing fees, etc).
In addition to the above, a contingency to cover unforeseen costs will be in the range of 10 to 20% of the sum of the direct and indirect costs. The designer must be aware of the project-specific costs of all such elements, so that he can monitor costs and promote methods of reducing total installation costs. In some locations, for example, labor and material costs could make a gabion wall more expensive than a poured concrete wall, which has minimal structural backfill.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
