Equipment and process required for processing stones into machine-made sand

With the vigorous development of infrastructure construction and the real estate industry, the demand for sand and gravel has been increasing year by year. However, the increasing depletion of natural sand resources has made mechanism sand the best alternative. So, how to process stones into machine-made sand? What equipment do I need to purchase during this process? This article will provide you with a detailed introduction.
1、 The basic process of processing stones into machine-made sand
Raw material preparation: Select suitable stone materials as raw materials, common raw materials include granite, limestone, river pebbles, etc.
Coarse crushing: Large stones are initially crushed by a jaw crusher to reduce their size to a size suitable for entering the next stage of equipment.
Intermediate crushing: The coarse crushed stone is further reduced in particle size by medium crushing using an impact crusher or cone crusher.
Fine crushing and sand making: The medium crushed stone is finely crushed and shaped by a sand making machine to meet the standards of machine-made sand in terms of particle size and shape.
Screening: Different particle sizes of sand and gravel are screened using a vibrating screen to ensure uniform particle size distribution in the final product.
Cleaning (optional): According to the requirements, impurities and dust in the machine sand can be cleaned by a sand washing machine to improve product quality.
2、 Required equipment and its functions
Jaw crusher: As a coarse crushing equipment, jaw crusher is mainly used for preliminary crushing of large stone materials, with the characteristics of simple structure, reliable operation, and easy maintenance.
Counterattack crusher/cone crusher: These two types of equipment are mainly used in the intermediate crushing stage. The impact crusher is suitable for medium hardness stone materials and has the advantages of uniform particle size and good particle shape for discharge; Cone crusher is suitable for hard stone materials and has the advantages of high crushing efficiency and long service life of worn parts.
Sand making machine: The sand making machine is the core equipment of the entire production line, responsible for finely crushing and shaping the crushed stone materials to meet the standards of machine-made sand. Common types of sand making machines include VSI sand making machines, HVI sand making machines, etc.
Vibration screen: Vibration screen is used to screen sand and gravel of different particle sizes to ensure uniform particle size distribution of the final product. Common types of vibrating screens include circular vibrating screens, linear vibrating screens, etc.
Sand washing machine (optional): The sand washing machine is mainly used to clean impurities and dust in the machine sand, improving product quality. Common types of sand washing machines include spiral sand washing machines, wheel bucket sand washing machines, etc.
3、 Precautions for equipment selection
Select equipment based on the characteristics of raw materials: Different stones have different hardness and properties, and the appropriate equipment type and model should be selected according to the characteristics of the raw materials.
Consider production demand: Select equipment that can meet the expected output and product quality requirements.
Pay attention to the energy consumption and maintenance costs of equipment: The energy consumption and maintenance costs of equipment directly affect production costs, and choosing energy-saving and easy to maintain equipment can reduce operating costs.
Choose a reputable supplier: When purchasing equipment, choose a supplier with a good reputation and comprehensive after-sales service to ensure the normal operation and timely maintenance of the equipment.
Processing stones into machine-made sand is a complex process that requires scientific and rational equipment configuration and strict production management. By selecting suitable equipment and following standardized operating procedures, high-quality machine-made sand can be produced to meet market demand. I hope this article can provide you with valuable reference and help your mechanism sand production business.
