Bulk material refers to a mixture in granular or lumpy form that can be poured. Bulk material is referred to as bulk goods when it occurs in large quantities. A prerequisite for the handling or transport of bulk materials is their suitability based on their physical properties. These are goods delivered in large quantities to retailers and companies. Bulk materials include building materials such as sand and gravel, natural stone, cement, and raw materials such as coal, ores, and salts. Foodstuffs such as grain, sugar, and flour also fall into this category.
