As one of the main raw materials for the production of concrete, sand and gravel have become a shortage of materials in the engineering field. Stone is a major support for the country’s infrastructure. The country’s investment in infrastructure projects has increased, and the demand for stone has also increased. The good market situation will attract more investors to enter the field of stone materials. Production and operation is a technology. Today, let’s take a look at the “hands-on lesson” of this technology: What machines are available in stone production equipment? How did the sand and gravel plant achieve a profit of tens of millions a year?
- What kind of machines does the stone production equipment have?
The basic configuration of the stone production line includes feeding, crushing, sand making, screening, sand washing and other links. The crushing and sand making links are the main leading links, and the others are auxiliary functions. Crushing is to crush large pieces of raw materials into stones and sand making. It is to further crush small stones with a particle size of less than 55mm to make coarse sand, medium sand, fine sand, and ultra-fine sand to meet different construction needs. These two types of equipment do not necessarily appear at the same time. They can be used separately, or they can be combined to achieve a single line of crushing and sand making. Customers can choose equipment according to their actual needs.
Sand and gravel production process
Feeding: through the vibrating feeder, the raw materials can be evenly fed into the crushing process;
Rough crushing: There are many types of crushing equipment. In normal production, it is divided into coarse crushing and fine crushing. Generally, jaw crushing equipment will play the role of rough crushing, and the hourly production capacity is realized according to the configuration, which can meet the various needs of users.
Fine crushing: Fine crushing is crushing equipment between coarse crushing and sand making. Cone crushers and impact crushers are usually used. The crushing equipment is configured according to the nature of the material. The impact crusher is suitable for various coarse, medium and fine materials with a compressive strength of not more than 350MPa, and the finished product has the advantages of good grain shape and less powder; the production capacity of the cone crusher is 2 to 3 times that of the traditional type, and the degree of automation is high, stable operation, capable of crushing hard materials.
Sand making: The sand making machine is mainly used to process the crushed stones into a particle size that meets the needs of users.
Screening: Screening is the process of crushing and sand making stones of different sizes and sizes, which need to be sorted and classified by screening equipment.
Sand washing: Sand washing can clean the dirt and dust in the sand. It can be used with sand making equipment to achieve high cleanliness and less sand loss. The sand cleaned by the sand washer has high cleanliness and good quality, which greatly improves the quality of machine-made sand.
- It is not a dream for the sand and gravel plant to make tens of millions of profits every year!
Many people are skeptical about whether the sand and gravel plant can make money. In this case, let’s work out an account together to see how profitable the gravel plant is?
The above data is the price of sand and stone aggregates in recent months. The average price is about 70-80 tons/ton. In some developed areas, the price will be higher. It is not a problem that the price per ton exceeds 100 yuan, while the price of raw materials is average. It is 20-30 yuan/ton, and the profit of one ton of finished products is at least 40 yuan. The current production equipment can easily achieve a thousand-ton level of production per hour. Based on an hourly output of 1,000 tons, working 10 hours a day, a year’s profit can reach 15 million, excluding site costs, labor costs, water and electricity costs, etc., making a profit every year tens of millions are very feasible.
The profit of investing in sand and gravel plants is infinitely possible. Of course, the production of large-scale sand and gravel plants must require a lot of initial investment. If you want to invest in a small gravel plant, it is also possible. The general trend guarantees the profits of the gravel plant. When choosing equipment with small output, your initial investment if there is less, the payback will be quicker in the later period, and it is easy to make millions of profits every year.
