Coal gangue is a solid waste discharged during coal mining and coal washing. It is a kind of black rock with a lower carbon content and harder than coal that is half-baked with the coal seam in the process of coal formation.The amount of coal gangue mined every year is huge, and the emissions of coal gangue have also increased. When coal gangue is discarded, it will occupy a large area and may pollute the land and ecological environment. Therefore, the reuse of coal gangue waste has always been an important topic in my country’s research.
Coal gangue is a kind of recyclable solid waste. Friends in the sand and gravel industry are very familiar with it. Relevant data show that coal gangue accounts for 15%-20% of coal production and has considerable investment profits. It is the main raw material for coal gangue bricks. After the processing and treatment of professional mining equipment, it can turn waste into treasure and continue to exert its due value and save resources.In the mining equipment market, coal gangue crushing operations can be realized by roller crushers, impact crushers, jaw crushers, and fine crushers.，
“I have a coal washing plant, and the gangue washed down cannot be lost. What equipment does it take to open a coal gangue brick plant?”
“There is a large coal mine near my home, which produces more than 100,000 tons of coal gangue every year. I want to open a coal gangue brick factory. How much investment does it take?”
“I heard from friends that the coal gangue brick-making market has good prospects. What is the specific process flow?”
Recently, I have received many inquiries from friends about such issues. You must be planning to invest in coal gangue brick making. You also have such doubts. Today we will explain in detail.
How much does it cost to build a coal gangue brick factory?Plan in advance, don’t panic about investment
The production of coal gangue bricks generally includes processes such as raw material processing, mixing, digestion, wheel milling, forming, maintenance, and stacking of finished products. These all require a cost. The investment in shredder equipment requires funds of about 10-1 million yuan (depending on the choice of output, configuration model, etc.), and the relevant procedures need to be processed in the early stage, which is about a few thousand yuan, labor, factory floor area, electricity, etc., the overall cost is about 200,000-500,000 yuan.
To see if a project has investment value, it depends not only on the expenditure of equipment, but also on profits and prospects. This is the key to your income.Let’s take a look at the specific case of a coal gangue brick factory with an annual output of 60 million pieces, and what is its income?：
The price of coal gangue raw materials is about 16 yuan/ton, plus 30 yuan for freight, 1 yuan for taxes, and other expenses. The cost of a ton of coal gangue is 50 yuan/ton.
The price of coal gangue bricks is about 1 yuan/piece, and one ton of coal gangue can produce about 300 pieces of coal gangue bricks, that is, one ton of coal gangue can earn about 300 yuan.
The gross profit of one ton of coal gangue to make bricks is about 250 yuan, and the annual output of 60 million pieces of coal gangue bricks requires 20,000 tons of coal gangue, and the annual income can reach 5 million yuan.
Excluding labor, water, electricity, equipment, site and other expenses of about 500,000, the annual income is 4.5 million, and the profit is still very considerable!
What procedures are required for environmentally friendly coal gangue brick factories?
The production cost of coal gangue brick factories is low. The use of coal gangue to make bricks not only saves land, but also consumes mine waste. It is a low-carbon building material that is conducive to environmental protection, and the brick-making process is convenient.Many friends have been eyeing this project for a long time, but they are worried about environmental protection. In fact, the impact is not great. They only need to purchase environmentally friendly equipment reasonably to solve this problem.
Before purchasing equipment, let’s first understand what procedures are required to open a coal gangue brick factory?The details are as follows；
- Get the approval of the NDRC (production qualification)；
- Entrust the “Environmental evaluation agency” to conduct an environmental evaluation of the project, and then hold a review meeting after the report is released. After it is passed, it can be built.；
- Submit an application report to the Environmental Protection Bureau；
- Entrust the “environmental monitoring station” to conduct environmental monitoring within three months, issue an environmental monitoring report, and finally invite the Environmental Protection Bureau to conduct the overall environmental acceptance. After receiving the report, it can be officially produced.
- In addition, you also need to go to the Land Administration (land use), the industrial and commercial department (business license), and the tax department (tax registration) to go through corresponding procedures.
In addition to going through relevant formalities with the local department, it is also necessary to understand whether the coal gangue brick factory meets the requirements of clean production, whether it can discharge pollutants up to standard, whether it can maintain or improve the environmental quality of the area and other related issues, and be fully prepared.
