The compressive strength of different types of desiccated sludge briquette is obviously different with the addition proportion,The product is generally used in mining, sewage sludge, medical sludge treatment.Mainly due to the different composition of sludge itself will also cause the difference in its cohesiveness, generally expressed in water content, inorganic matter and the different unit points contained.

The compressive strength of different kinds of dried sludge briquette also has obvious differences with the different addition ratios. This product is generally used for the treatment of mine, wastewater sludge and medical sludge. The main reason is that the different composition of sludge itself will also cause the difference of its cohesiveness, which is generally manifested in the difference of water content, inorganic matter and component. Organic components in medical sewage sludge mainly include: Protein, sugar, lipid and a large number of reproductive bacteria and parasites, etc.The organic components of domestic wastewater sludge and brewery wastewater sludge contain not only proteins, sugars, bacteria and parasites, but also some fibrous organic compounds, among which brewery wastewater sludge has high content of fibrous organic compounds. The research on the preparation of biomass briquette​ in Tsinghua University found that for long fibrous biomass, biomass forms a network in the briquette forming process. In a certain range, with the increase of screening, the fiber length increases, the crosslinking between biomass increases, and its forming rate increases. However, for granular biomass, there is basically no crosslinking between biomass, and it is difficult to form a reticular connection.
