my country's economic and social development has entered a new stage of high-quality development, and the small-scale and extensive development model is gradually clearing up. In the machine-made sand and gravel industry, large-scale and large-scale production has gradually become the consensus of the industry. In the past, the small-scale production of one household was relatively simple in the configuration of the production line. Today, how to configure the large-scale production line has become the concern of many customers. In short, there are some basic considerations to follow when configuring a large-scale production line.
These conditions are indispensable for designing a sand and gravel aggregate production line
1. Reach the designed annual production capacity
The first element is to achieve the design annual production capacity. At present, according to national industry standards, the acceptance of crusher output is based on the instantaneous output of new wearing parts, full load, and continuous production. However, in the actual production process, the conditions of full-load continuous production are often not satisfied, whether it is equipment The reason, or the reason for the process design, or the reason for the production management. The wearing parts of the equipment are new and the output is high. After the equipment is put into production, as the wearing parts wear, the output will drop, and some will even drop by more than half. Therefore, when selecting equipment according to the average output of the equipment table, the designer of the production line must pay special attention to the equipment whose output is greatly reduced when the wearing parts wear out in the background, so as to avoid the reduction of the actual production output due to the wear of the wearing parts. .
2, The quality of finished sand and gravel aggregates.
The second condition for the success of a sand aggregate production line is the high quality of the finished aggregate. Product quality can not only meet the national standards, but also meet the needs of the market. High-quality aggregates (coarse aggregates and fine aggregates, fine aggregates are sand), firstly, the particle shape should be good, and the senses should be good; secondly, the gradation should be reasonable. Especially for machine-made sand, high-quality machine-made sand products must not only meet the sand requirements of commercial concrete, but also meet the requirements of higher standards for ready-mixed mortar sand. Reasonable continuous grading can meet the needs of high-quality concrete, and the two are indispensable.
3, the craftsmanship.
The third condition for the success of the sand and gravel aggregate production line is that the process is better. The good process is reflected in the simplicity of the process, and the equipment is convenient and simple to use and maintain. The on-site conditions of the aggregate production line are difficult, and it is difficult to recruit capable maintenance personnel. Therefore, the "dumb machine" with simple operation and convenient maintenance is the first choice for the aggregate production line. Good craftsmanship is also reflected in the fact that the number of equipment is small and the model is as uniform as possible. The number of equipment is small, the failure points are reduced, and the civil construction cost will be reduced accordingly; the model is unified, the cost of spare parts is low, and the management is convenient. A good process is that the equipment has a high operating rate and a long time of continuous trouble-free operation.
4, the degree of automation.
The fourth condition for the success of the sand and gravel aggregate production line is to improve the degree of automation, to achieve intelligence, to reduce the number of employees, to improve the operation rate of equipment, and to improve the continuous operation time without failure.
5. Impurity content.
The aggregate product of the production line must meet the relevant requirements of impurity content. High-quality concrete has higher and higher requirements for soil content. The seemingly simple problem may be the reason for the failure of the project. There is more rain in the south and water shortage in the north. Some mines contain less soil on the surface, some contain more soil, and some There are layers of soil and so on. Different processes need to be adopted in different situations, otherwise it will cause the failure of the project or increase the huge cost of post-transformation.
The above are some issues that need to be considered when designing a machine-made sand and gravel production line, especially a large-scale production line. The ultimate goal is to make the design of the production line meet expectations, and in actual production, the performance is good.
