With the depletion of natural sand resources, the manufactured sand market has shown great potential and vitality. Especially in recent years, there has been a huge demand in the construction market. Because the production of manufactured sand is not affected by climate and seasons, its whole production process can be effectively controlled and free from environmental restrictions, which is conducive to large-scale production and boosts the rapid development of the sand and gravel market. So how to configure the artificial sand making plant and choose a good artificial sand making machine?
Two Basic Criteria of Artificial Sand Making Plant
The sand making plant adopts a complete set of stone crushing equipment to process raw ore and produce manufactured sand and aggregates. The equipment configuration of different production lines is different, and two basic criteria shall be followed during configuration:
1. Understand material characteristics and requirements
Before configuring the aggregate production line, it is necessary to find out the properties of the materials to be processed, such as hardness, size, etc. Consider the type of crusher and sand making machine to be configured according to raw materials, output requirements and finished product particle size requirements. The selection of crushing and sand-making equipment should not only meet output requirements, but also take into account the feed inlet size to prevent material feeding blockage.
2. Understand your economic strength
The economic foundation determines the superstructure. When configuring sand and gravel production lines, we should choose different production lines according to our own investment strength. Don't buy blindly. The one that suits you is the best. Users shall make the configuration according to their actual purchasing capacity.
Cost budget of artificial sand making plant:
- 1. The purchase cost of raw materials is different. The ore prices in different regions are different. If there are their own mines, they do not need to be considered;
- 2. Infrastructure construction cost, including standardized plant, closed storage warehouse, comprehensive environmental protection facilities, roads in the plant, water supply and drainage, power supply and distribution, office and living facilities, etc;
- 3. The cost of complete equipment, including the cost of feeding, crushing, screening, sand making and other complete equipment;
- 4. The operation cost of the production line, including workers' wages, utilities, maintenance expenses of vulnerable parts, etc.
The investment cost budget of sand making plant varies greatly according to different raw materials and production scale.
How to process artificial sand?
The equipment configuration of artificial sand making plant includes vibrating feeder, coarse crusher, medium and fine crusher, vibrating screen, sand making machine, belt conveyor. Among them, feeders, vibrating screens and conveyors are auxiliary equipment.
1. Feed
The stones blasted from the mountain are delivered to the vibrating feeder by dump trucks. Vibrating feeder has strong adaptability, stable operation and high cost performance. It is a feeding equipment widely used in sand and gravel enterprises. The vibrating feeder can feed the crushing equipment continuously and evenly, effectively prolonging the service life of the equipment. Small volume, light weight, small power, compact structure, convenient installation, low operation cost and low investment cost.
2. Coarse and Fine Crushing
According to different crushing purposes, crushers are divided into coarse crushing and medium fine crushing: coarse crushers can process large stones to medium particle size at one time; the medium and fine crusher is mainly used to further crush and reshape the coarse crushed stone to meet the high standard requirements of construction projects for stone. The vibrating feeder evenly sends the stones to the jaw crusher, and the broken stones from the jaw are broken for the first crushing, that is, coarse crushing. The stones broken from the jaw are then transported to the cone crusher or impact crusher through the belt conveyor for secondary crushing, that is, fine crushing.
3. Sand Making and Screening
The finely crushed materials are sent to the sand making machine by belt conveyor for fine crushing, and the finely crushed materials are screened out by vibrating screen.
The entire production line can be completed via the above three steps. However, for projects with strict requirements on sand powder content, a sand washer can be added after fine crushing and screening. Circular vibrating screen and linear vibrating screen are common in sand production lines. Belt conveyors are the hub of sand production lines. It features low energy consumption, high production efficiency, large conveying capacity, flexible operation, cost-effectiveness and high practicality.
