Cement grinding plant or cement grinding unit, grinding station is a necessary section of the cement manufacturing plant. What does cement grinding plant do? In brief, cement grinding plant helps to grind clinker into finished cement.
For investors who are new to the cement industry, now is the perfect time to invest in cement grinding plant. Here are some reasons:
- Growing demand: With the advancement of global infrastructure construction and the acceleration of urbanization, the demand for cement is increasing, especially in developing countries and regions.
- High return on investment: The construction cost of cement grinding station is relatively low, but the market demand is stable, the profit margin is large, and the return on investment is high. Not susceptible to economic fluctuations, low investment risk.
- Low operating costs: The operating costs of modern mill stations are low, especially in the case of stable raw material and energy supply, and production costs are easy to control.
- Strong market adaptability: The grinding station can flexibly adjust the production scale and product types to adapt to changes in market demand.
- Regional market advantage: cement grinding station can serve the regional market nearby, reduce transportation costs, and improve market competitiveness.
- Recycling of resources: industrial waste residue and slag can be used as raw materials to reduce waste discharge and save resources, which is in line with the concept of circular economy.
- Policy support: The cement industry is closely related to national infrastructure construction, with strong policy support and good industry prospects.
How much does it cost to start a new cemeng grinding plant? Today we take a small and medium-sized cement grinding unit case(with an annual output of 100,000 to 1 million tons) as example, and help you calculate th total cost of cement gridning plant.
As we all know, cement grinding plant is generally composed of various production section, and each section set some cement equipment for different purpose. We will list the cost according to these sections.
Please note that the specific price may change due to market fluctuations and equipment configuration. The following is a rough estimate in RMB (ten thousand yuan)
Raw material handling and conveying system cost
The raw material storage area of the cement grinding plant needs the following equipment:
- Stacker and reclaimer: the system is used to handle raw materials and put them in storage.
- Conveying equipment: involving belt conveyors and screw conveyors are used to carry the raw material from the stockpile area to the designated spot in the storage.
- Weighting equipment: it is used in weighting and metering the raw material, ensuring accuracy and stability of the inventory.
The total investment in this section is about 3 million yuan.
Grinding system cost
- Cement ball mill: it is applied for grinding material to make the material powder arrive the desired fineness.
- Vertical roller mill: another kind of powder grinding equipment, generally be employed in grinding materials with higher hardness.
- Separator: grading the milling material by particle size and separating out the fine powder and coarse powder in compliance with requirements.
- Grading device in mill and other equipment.
The total investment in this section is about 20-60 million yuan (according to different production and equipment selection).
Dust removal system cost
- Baghouse dust collector: serving for collecting and filtering the gust generated during the grading process, and it is suitable for capturing fine, dry, non-fibrous dust.
- Electrostatic precipitator: remove particulate smoke from the flue gas emitted by coal or oil-fired boilers.
The total investment in this section is about 6 million yuan.
Packaging and delivery system cost
Automatic packaging machine, conveyor belt, loading system are main equipment used in this section, one set of packing and delivery system require 8 million yuan.
Storage System cost
Cement silo and cement warehouse are generally used in storage system of cement grinding plant. A small and medium-sized storage system require 2-4 cement warehouse, and total investment in this section is about 6 to 12 million yuan.
Electric system cost
Transformer and electronic control system are main equipment in the electric system, the total investment in electric system is about 3 million yuan.
Ancillary facilities cost
One set of ancillary facilities include laboratory equipment, office facilities, environmental protection facilities, etc. the total cost is about 6 million yuan.
Civil engineering cost
The investment of this part is about 12-30 million yuan (depending on the size and local construction cost).
