Overview
Non-pulverized sand is a specialized type of sand that maintains its granular structure without breaking down into fine particles. Unlike regular sand, which can degrade over time, non-pulverized sand is known for its durability and stability. It is commonly sourced from natural deposits and processed to meet specific industrial standards. This type of sand is particularly valued in industries where consistency and longevity are critical. Its resistance to pulverization makes it ideal for applications that require long-term structural integrity, such as in construction and foundry work.
Physical and Chemical Properties
Non-pulverized sand exhibits several key physical properties that distinguish it from ordinary sand. It has a coarse granular structure, with particles that resist breaking down under pressure or friction. The density typically ranges from 1.4 to 1.6 g/cm³, and it is insoluble in water. Chemically, non-pulverized sand is inert and does not react with most substances, making it suitable for use in harsh environments. Its thermal stability allows it to withstand high temperatures without decomposing, which is essential for foundry applications.
Main Applications
Non-pulverized sand is widely used in the construction industry for making concrete and mortar, where its durability ensures long-lasting structures. It is also a key material in foundry work, where it is used to create molds for metal casting due to its ability to withstand high temperatures. In addition, non-pulverized sand is employed in filtration systems, particularly in water treatment plants, where its granular structure allows for efficient filtration without clogging. Its stability and resistance to degradation make it a preferred choice for these applications.
Safety and Storage
Handling non-pulverized sand requires basic safety precautions to minimize health risks. Workers should wear protective gear, such as masks and gloves, to avoid inhaling dust particles or skin irritation. Proper ventilation is also recommended when working in enclosed spaces. Storage conditions are equally important. Non-pulverized sand should be kept in a dry, well-ventilated area to prevent moisture absorption, which can affect its performance. Bulk storage should be covered to protect it from environmental elements.
B2B Procurement Guide
When procuring non-pulverized sand for industrial use, buyers should pay attention to several factors. Particle size distribution is critical, as it affects the sand's performance in specific applications. Moisture content should also be verified, as excess moisture can lead to clumping and reduced effectiveness. Price is another consideration, with costs typically ranging from $20 to $50 per ton, depending on quality and source. Buyers are advised to request samples and conduct tests to ensure the sand meets their requirements before making bulk purchases.
