Investigate the local raw material market in your area. Choose the raw material that is abundant in supply, convenient for transportation and has a low price. The indispensable condition for setting up a non-fired block brick factory is resources. Unlike the previous clay-fired brick factories, which could freely occupy land and take soil without worrying about resources. The channels for the waste resources such as fly ash and coal gangue used in setting up non-fired brick factories are relatively specialized, and most of them are piled up in a relatively concentrated place. Whoever sets up the factory first will monopolize the source of materials and occupy the market to prevent latecomers from participating in the competition.

2. Investigate the local brick sales market in your area, analyze which bricks are more popular and practical, and cater to the tastes of your target customers. This is also in line with the market.

3. Find out how many brick factories there are in your local area and understand the strength of your competitors.

4. Fund allocation mainly includes equipment investment, site investment, working capital, etc.

Raw materials

There are many raw materials for non-fired brick-making machines, such as sand, stone powder, cement, fly ash, coal gangue, water slag, construction waste, etc. In a word, any raw material that can be combined with cement can be used by non-fired brick-making machines to produce non-fired bricks.

How to prepare the ingredients? In fact, there is no standard formula either. The key lies in the specific conditions of your local area. If you already have some raw materials that don't cost you money, of course you can use more. For the more expensive ones, you can use relatively less. If you mainly use fly ash or stone powder (known as low-grade cement), the amount of cement can be slightly reduced, and the bricks made will be relatively better. However, it is recommended that you use a mixture of powdered and granular raw materials. This way, the combination will be better and you can save some cement, thereby reducing the cost of raw materials.

The list of waste residues eligible for value-added Tax preferential policies for non-fired brick machines (Investigate the preferential policies for each raw material aspect, taking China as an example)

Mining and beneficiation waste residue refers to the waste rock, coal gangue, debris, powder, dust and sludge produced during the process of mineral resource extraction and processing.

Ii. Smelting waste slag refers to converter slag, electric furnace slag, ferroalloy furnace slag, alumina red mud and non-ferrous metal ash slag, but does not include blast furnace water slag.

Iii. Chemical waste residue refers to pyrite slag, pyrite calcination slag, sulfuric acid slag, gypsum, phosphogypsum, phosphate rock calcination slag, cyanide-containing waste residue, calcium carbide slag, phosphate fertilizer slag, sulfur slag, alkali slag, barium-containing waste residue, chromium slag, salt sludge, total solvent slag, yellow phosphorus slag, citric acid slag, desulfurization gypsum, fluorogypsum and waste gypsum mold.

4. Other waste residues refer to fly ash, silt and sand from rivers (lakes, seas, canals), construction waste, and sludge produced by urban sewage treatment plants when treating sewage.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
