With the shortage of sand and stone resources, sand and stone production line has attracted the attention of many investors because of its high economic benefits and bright investment prospects. At this time to understand the process of sand and stone production line to optimize equipment configuration, saving capital investment is of great benefit. This article introduces the process of sand and stone production line.
Sand and stone production line process:
1. Feeding process: The bulk ore from the raw material bin is fed evenly and continuously into the primary crushing equipment by the mine feeder. At present, vibrating feeder is commonly used in the mining industry. It has small volume, simple structure, stable performance and high cost performance.
2. Crushing process: The crushing stage includes the special coarse crusher, medium and fine crusher (optional). The specific configuration of which crusher needs to be selected according to the hardness of ore.
According to the different working principles, crushers are divided into extrusion type and impact type. For ores with high hardness, it is recommended to choose extrusion crushing equipment (jaw crusher, cone crusher, etc.), and for ores with medium hardness, it is recommended to choose impact crushing equipment (hammer crusher, impact crusher, etc.).
3. Sand making process: According to the specifications of finished products and the market trend, sand and stone production line can be configured with sand making machine after the crushing process, so as to further process the stone with gravel specifications, produce mechanism sand that meets the requirements of the industry, and enrich the types and sales of finished products.
4. Screening process: Sand and stone that has been crushed needs to be screened. The vibrating screen has both screening and feeding functions, which is able to control the specifications of finished products with excellent quality.
5. Conveying process: Belt conveyor is responsible for conveying materials in each process and finished products, is an important supporting equipment of sand and stone production line.
Key points of process design of sand and stone production line
1. Adapt measures to local conditions, consider the terrain, slope and traffic problems of the production line site, and use inertia to transfer materials to each stage, which can save energy consumption and time.
2. Combined with the characteristics of mining stone, production demand, material demand, and project budget, comprehensive consideration of working conditions.
Technology characteristics of Luoyang Dahua sand and stone production line
1. Small footprint, stable operation. By optimizing the process flow and reducing complexity, the whole sand and stone production line occupies a smaller area and runs faster.
2. Environmental protection configuration, green production. Can be equipped with complete dust removal, noise reduction, spray device for the whole sand and stone production line, in line with the requirements of environmental protection policy.
3. Easy maintenance and low operation cost. The quality of sand and stone production equipment, raw materials and production process are strictly controlled to reduce maintenance costs.
4. Higher degree of automation, save labor costs. It can realize the production line process start, conversion, stop, alarm and other operations of remote control.
