Sulfur, along with oil, coal, table salt and limestone, belongs to the five main raw materials of the chemical industry and is of strategic importance for providing food to the population, since in addition to nitrogen, phosphorus, potassium, calcium and magnesium, it is a necessary nutrient mineral element for plants, a source of soil fertility and increased yields.
There are several commercial forms of sulfur: lumpy, granular and liquid forms are considered the main ones.
Of all the commercial forms of sulfur, granular sulfur is becoming the most popular. Among its advantages are flowability, convenience and safety during storage and transportation (by any type of transport), low losses, and improved sanitary and hygienic working conditions when used in production. Varying the technological methods of granulation (air, fluidized bed, water) allow you to adjust the size (from 0.5 to 6 mm) and the shape of granules (grains, pellets, capsules, balls, etc.). The sulfur grade — 9998 (purity 99.99 is actually achieved) allows the product to be used in technologies that require high-quality substances in the production process, reduce costs and increase the output of finished products.
