At present, the specifications of ceramsite are divided according to the particle size, with 15mm as the boundary, 5-15mm is small ceramsite, and above 15mm is large ceramsite.

Affected by the production process, the uses of large and small ceramsites are different. Large ceramsites are more used in blocks, and small ceramsites are more used in wallboards.

Large ceramsite is added as the raw material of the block. After curing, the whole is cut into standard size squares. During the cutting process, the ceramsite particles are allowed to be cut. Therefore, the ceramsite added to the block is not affected by the particle size. Large ceramsite occupies more volume, the blocks produced are lighter, and have better heat preservation, heat insulation and sound insulation effects.

The thickness of the weakest part of the lightweight wallboard is less than 20mm. Due to the thickness limitation, the ceramsite as one of the raw materials is added to the wallboard, and required particle size is 5-10mm and 10-15mm.

The source of small ceramsites is to purchase standard small ceramsites directly from the ceramsite factory, and the price is about twice that of large ceramsites. The raw material balls granulated in the production process of the ceramsite factory have a particle size of 10mm or larger. They will expand during the firing process. The finished ceramsite particles with good swelling effect have a particle size of more than 20mm. Only part of the scraps in the firing process, the particle size is less than 15mm, but the proportion is small. Therefore, the output of small ceramsite in the ceramsite factory is low.

The other is to crush and screen large ceramsites to obtain small ceramsites that meet the particle size. Considering the purchase price of large ceramsites and small ceramsites, many manufacturers will choose to crush large ceramsites. This kind of ceramsite is generally an expanded ceramsite with low strength, so you can choose a roller crusher.

Double roller crusher has simple structure, adjustable gap, large capacity and low price. Henan Zhengzhou Mining Machinery Co., Ltd. is deeply involved in the ceramsite industry and has rich experience in designing, manufacturing and onsite use of ceramsite crushing equipment. Welcome to consult!
