Zirconia silicate beads provide long media lifespan and facilitate efficient grinding processes. Their dense homogeneous structure prevents wear-and-tear damage.
These granulated and shaped media undergo two processes to ensure they retain their shape: washing to eliminate organic impurities and baking to set.
Size
zirconia silicate beads offer an economical and sustainable alternative to glass or alumina media for grinding and dispersion tasks, without needing replacements as often. Commonly utilized within wheel or compressed air blasting systems, zirconia silicate beads can also be tailored specifically for specific applications.
Zirconia Silicate Beads come in multiple sizes to meet your specific process needs. Not only are they cost-effective for wet or dry finishing processes, they’re also highly effective in extracting embedded contaminants from stainless steel surfaces – an invaluable advantage. With low wear rates and compatibility with both wheel blasting systems and compressed air blasting systems.
As one- and two-millimeter grinding beads are typically used for milling and grinding CaCO3, printing inks, foodstuffs, pharmaceuticals and metallic minerals; their lifespan has also proven to be three times longer than standard glass beads.
When homogenizing bacteria, use 0.1 mm beads. When dealing with tough and fibrous tissue samples, pre-chopping or cryopulverizing the sample prior to bead beating helps decrease how long beads spend in the mill chamber.
Once beads have been formed, they undergo a selection process where any misshapen or defective media is removed to ensure you only receive high-grade zirconia silicate media when ordering it. After being selected and baked in our finished products kiln to help retain their shape, they undergo another final baking process so as to be safe to handle and use in your application while also helping avoid contamination issues which may impede performance or increase efficiency of production and increase part production per hour.
Temperature
Zirconia silicate beads have become an indispensable resource in materials processing applications. Their hardiness, toughness, chemical inertness and longevity have long made them the go-to choice for milling/dispersing printing inks/dyes/dye mixtures/pharmaceuticals/minerals; although there are alternatives that offer similar capabilities. Proper handling practices, optimization of process parameters, regular inspections are all key to prolonging their lifespans.
Selecting the appropriate media size is also critical to success. Larger size media tend to last longer, yet selecting one that corresponds with particles that need breaking up is essential to speedy milling/dispersing/grinding processes. By choosing an ideal size media size combination, milling/dispersing/grinding processes will be completed more quickly and efficiently.
Before loading media into a milling machine, it is wise to thoroughly inspect them for signs of damage or deformation. This will help ensure only top quality beads are used in your process.
Zirconia silicate beads can be used to effectively disperse paints and pigments, produce ultra-fine dispersion of chemicals like pesticides and even disperse mineral applications like calcium carbonate.
These beads have another exceptional application in lysis of tough tissues such as fecal or soil samples containing bacteria. They are superior to Garnet (an iron-aluminum silicate sharp particle), as they do not fragment during beadbeating and quickly break apart the cells of bacteria, speeding up both homogenization and lysis processes. Furthermore, they are useful for dispersing biomaterials like chitosan and nanomaterials, saving valuable research time while eliminating multiple dilutions of samples.
Cooling System
Zirconia silica beads are an affordable and practical medium suitable for various lab applications. Their durability, resistance to contamination and ease of cleaning make them the ideal solution. Inovatec provides various sizes so that you can find one to meet the specific requirements of your process.
Cooling systems for zirconia grinding machines are essential, as their effect can drastically alter machine efficiency. Zirconia beads produce heat during grinding processes that causes chamber temperatures to increase – compromising overall grinding process efficiency. Although there are ways of preventing this from happening – such as adding cooling solvents – adding them can be costly or may not always be feasible depending on circumstances.
Cooling systems for yttria stabilized zirconia beads are vitally important as they can influence the quality of the final product. As these beads contain more zirconia than other types of zirconium silicate beads, yttria stabilized zirconia beads are more durable and able to withstand more pressure compared with their silicate counterparts; additionally, these beads can tolerate higher temperatures which makes them ideal for certain applications such as quantitative PCR sample preparation.
