Copper ore, also known as copper slag sand or copper furnace sand, is the slag produced after copper ore is smelted and extracted, also known as molten slag. The slag is processed by crushing and screening according to different uses and needs, and the specifications are expressed by the mesh number or the size of the particles. Copper ore has high hardness, shape with diamond, low content of chloride ions, little dust during sandblasting, no environmental pollution, improve the working conditions of sandblasting workers, rust removal effect is better than other rust removal sand, because it can be reused, economic benefits are also very considerable, 10 years, the repair plant, shipyard and large steel structure projects are using copper ore as rust removal.
When quick and effective spray painting is needed, copper slag is the ideal choice. Depending on the grade, it produces heavy to moderate etching and leaves the surface coated with primer and paint. Copper slag is a consumable silica free substitute for quartz sand.
Iron and steel slag can be divided into blast furnace slag and steelmaking slag. On the first hand, the former one is produced by the melting and reduction of the iron ore in the blast furnace. On the other hand, the latter one is formed during the steelmaking process by changing the composition of iron.
Glass sand medium is an economical, silicon-free, consumable abrasive that provides aggressive surface contouring and coating removal. Made from 100% post-consumer recycled glass bottle glass, Junda Glass sand has a whiter and cleaner surface than mineral/slag abrasives.
Zircon sand (zircon) is extremely resistant to high temperatures, and its melting point reaches 2750 degrees Celsius. And resistant to acid corrosion. 80% of the world’s production is directly used in the foundry industry, ceramics, glass industry and the manufacture of refractory materials. A small amount used in ferroalloy, medicine, paint, leather, abrasives, chemical and nuclear industries. Very small amounts are used for smelting zirconium metal.
Zircon sand containing ZrO265 ~ 66% is directly used as the casting material of iron metal in the foundry because of its melting resistance (melting point above 2500℃). Zircon sand has lower thermal expansion, higher thermal conductivity, and has stronger chemical stability than other common refractory materials, so high-quality zircon and other adhesives together have good adhesion and are used in the casting industry. Zircon sand is also used as bricks for glass kilns. Zircon sand and zircon powder have other uses when mixed with other refractory materials.
Junda garnet sand, one of the hardest minerals. We closely cooperate with the leading waterjet equipment manufacturers to develop the higher performance and more cost-effective products for the customers. We remain the garnet leading supplier in China who keep product research, development, performance and cost-effectiveness.
Junda garnet sand is divided into three kinds, respectively, rock sand, river sand, sea sand, river sand and sea sand have excellent cutting speed, there is no dust products, clean effect, environmental protection.
Walnut shell grit is the hard fibrous product made from ground or crushed walnut shells. When used as a blasting media, walnut shell grit is extremely durable, angular and multi-faceted, yet is considered a ‘soft abrasive’. Walnut shell blasting grit is an excellent replacement for sand (free silica) to avoid inhalation health concerns.
Rutile is a mineral composed primarily of titanium dioxide, TiO2. Rutile is the most common natural form of TiO2. Predominantly used as a raw material for chloride titanium dioxide pigment manufacture. Also used in titanium metal production and welding rod fluxes.It has excellent properties such as high temperature resistance, low temperature resistance, corrosion resistance, high strength, and small specific gravity.
Corn Cobs can be used as an effective blasting media for a range of applications. Corn Cobs are a softer material similar in nature to Walnut Shells, but without the natural oils or residue. Corn Cobs contain no free silica, produces little dust, and comes from an environmentally friendly, renewable source.
