How to improve sand and gravel quality and reduce costs
The production of machine-made aggregates is divided into crushing, screening, and sand making. According to the size of the raw materials, single machine-made sand or graded crushing sand making production schemes are selected. Jaw crushers, cone crushers, impact crushers, How to combine sand machine and other sand and gravel equipment should be based on the physical and chemical properties of the selection, and the higher the performance of the sand and gravel equipment and its adaptability, the better;
The finished material with a clear particle size can be obtained through enhanced screening configuration. The commonly used grading of coarse aggregates is divided into small stones (5-20mm), medium stones (20-40mm), and large stones (40-80mm). Construction sand is divided into coarse sand, medium sand, fine sand, and extra-fine sand.
The screen aperture and the number of screen layers of the vibrating screen can be selected as required. According to the aggregate size and gradation requirements, mature crushing equipment and vibrating screens and standard aperture screens are used to ensure the production of sand and gravel bones. The materials meet the grading quality standards and regulations determined by the specification.
The quality of the clean material is better. The mud content of the sand can be processed through the combination of screening configuration + sand washing configuration to improve the clarity of the sand. If you want to recover fine sand, you can introduce a fine sand recovery integrated machine for cleaning and recycling Synchronously, there is no need to worry about the amount of sand washed.
In addition to screening out the basic parameters needed in the cost control of sand and gravel aggregate production, control cost also needs to investigate and analyze the price of sand and gravel aggregate production equipment.
Due to the different indicators of raw material lithology, strength, hardness, etc., the production process, production process and production process involved in the production of sand and gravel aggregates are flexible and changeable. It is necessary to select different production process and production processes according to the actual situation. equipment.
For the production of natural sand and gravel aggregates, the production process of machine-made sand and gravel aggregates is relatively cumbersome, and the technical and professional requirements are very high. If there are omissions in the production process, it will have an impact on the quality of the finished aggregate. Will make the cost of the entire production skyrocket. Therefore, it is necessary to strictly control the production process, pay attention to the management of the production process, strictly monitor the entire production process, and supervise the cost of each production link, so as to promote the reliable and orderly development of sand and aggregate production.
