Description
This dataset describes the process of crushing 1 kg of refractory raw material during the production of refractory products, resulting in 0.989 kg of crushed refractory material. This process should be used in conjunction with the production of 1 kg of refractory raw material. The dataset is compiled from data on crushing processes across various refractory product manufacturing activities, including shaped refractories, unshaped refractories, and contracted refractory production. It includes energy consumption and particulate matter emissions associated with the crushing process, while infrastructure such as equipment manufacturing and facility construction is excluded from the system boundary of this dataset.
Activity Description
The dataset includes feeding and crushing processes. This process refers to mechanically processing refractory raw materials into substances with suitable particle sizes. Crushing is a technique that applies external forces to overcome the cohesive forces within the raw materials, causing them to break apart. Commonly used crushing equipment includes jaw crushers, roll crushers, and cone crushers.
Process Description
This dataset provides the service of 'crushing process, refractories'. The raw materials for producing refractory products are refractory raw materials, which commonly include limestone, gypsum, dolomite, natural rocks, coral, asbestos, cement, lightweight expanded sand, talcum powder, clay, silicon trioxide, cellulose, magnesia sand, sandstone, and black stone. This process is formed by aggregating data from multiple crushing processes in refractory product manufacturing. Assumptions about the raw material composition of this process are made based on the usage of refractory raw materials: it is assumed that 1 kg of refractory raw material contains 0.3 g of bauxite, 0.5 g of magnesia sand, and 0.2 g of magnesia-calcia sand.
