Analysis of production line of machine-made sand equipment
Cost analysis of production scheme of machined sand: investment and profit
Take a new dry-mixed mortar production line with an annual output of 150,000 tons as an example, with a total capital of 7 million yuan and a working capital of 2 million yuan.
(1) Cost: Raw material cost 170 yuan / ton + fixed fee cost 30 yuan / ton + sales and transportation cost 30 yuan / ton = 230 yuan / ton
(2) Gross profit: ordinary mortar sales price 300 yuan / ton-cost 230 yuan / ton = 70 yuan / ton
(3) Net profit: 70 yuan / ton gross profit-70 yuan / ton gross profit × 33% income tax = 46.9 yuan / ton
Output value: 300 yuan / ton × 75,000 tons = 22.5 million yuan
Net profit: 46.9 yuan / ton × 75,000 tons = 3.5175 million yuan
It takes 1.99 years to recover the investment
Factors Restricting Investment Costs
1) Production scale.
If the production scale is expanded, the number of equipment or production lines needs to be increased, and the total investment price will basically increase in proportion.
(2) Equipment model selection.
The price of imported sand equipment is generally 2-3 times that of domestic equipment, and the cost of operating power consumption and maintenance costs are high.
(3) Material of raw materials.
The harder the raw materials, the more difficult it is to process, and the investment costs are relatively high.
Factors affecting profit margins
(1) The price of sand with different quality mechanisms in different regions.
(2) The operating cost of the equipment is composed of workers' wages, utilities, and consumables.
(3) The management of the manufacturer, due diligence of management personnel and skilled operators are the key to increasing profits.
Four advantages of machine-made sand over natural sand
Machine-made sand has a larger specific surface area than natural sand. The strength of concrete prepared with machine-made sand is higher. The particles of machine-made sand are more angular and rough, which is conducive to bonding with cement and other cementitious materials. On the surface, it also brings the disadvantage of poor workability, and the stone powder in the machined sand can just make up for this defect. Because this stone powder is an inert admixture with small fineness, it not only supplements the lack of fine particles in the concrete, increases the solid surface area to water volume ratio, thereby reducing bleeding and segregation, and the stone powder can Cementitious materials such as cement and water form a soft slurry with water, which increases the volume of the coagulator and reduces the friction between the sand and gravel, thereby improving the workability of the concrete. The fine-quality machined sand has better initial slump performance, greater expansion, smaller loss over time, and better concrete performance than natural sand.
The production of machined sand can be combined with the production process of crushed stone, which greatly reduces the production cost of machined sand
The production of machine-made sand can be adjusted and controlled to produce machine-made sand, which can meet the design requirements of concrete mix ratio, with reasonable gradation and low void ratio, ensuring product stability and easy quality control. This is natural sand. Unexpected. The fine sand additive admixture is less than natural sand. Due to the use of gradation adjustment technology, the fine mechanism sand gradation is more reasonable, with less mud content and less mud mass, so the amount of admixture is less.
Conducive to the comprehensive utilization of mineral resources, both to solve environmental problems and improve the utilization of natural resources
The application of machine-made sand in concrete improves and alleviates a series of environmental problems caused by sand destroying and excavation, reduces the production cost of commercial concrete and the price of construction sand, improves the quality of construction projects, and reduces the pressure on construction sand. Because the sand production mechanism from the nearest material solves the long transportation distance, saves resources, reduces costs, and protects the environment.
The application of machine-made sand in concrete is a need for sustainable development
Looking into the future, machine-made sand is playing an increasingly important role in the construction market and has a brighter future. Concrete is the main raw material for the construction industry, and sand used in concrete is one of the important constituent materials of concrete.
Machine sand (man-made sand)
It is not restricted by the region, it can take materials on the spot and use different ore resources or even waste resources in various places, which not only solves the problem of environmental pollution, but also improves the utilization rate of natural resources.
Quality advantages The fixed source and mechanized production method ensure the stable quality of the machined sand and the adjustable and controllable grain shape.
Quality advantage Hard texture, small mud content, high surface energy and hydrophilicity, complete gradation.
