[0002] Blocks are block-shaped building products that are larger than clay bricks. The raw materials are widely available, in many varieties, and can be obtained locally at a low price. According to the size, they are divided into three categories: large, medium, and small. China mainly produces small and medium-sized blocks. Blocks with a height of 380 to 940 mm are medium-sized; blocks with a height of less than 380 mm are small. According to the material, they are divided into blocks such as concrete, cement mortar, aerated concrete, fly ash silicate, coal gangue, artificial ceramsite, and slag waste. According to the structural structure, blocks are divided into two types: dense and hollow. Hollow blocks have round holes, square holes, elliptical holes, single-row holes, and multiple-row holes. Dense or hollow blocks can be used as load-bearing walls and partitions. In the block processing and production, a block processing raw material screening device is required.
