"Cold-solidified briquettes" made by high-pressure briquetting machine using sludge, dust removal ash, and iron scale produced by steelmaking as raw materials, adding lime, and using organic glue as a binder.

For briquetting equipment, roller skin is one of the key parts and plays an important role in the equipment performance. The life of the roller skin determines the service time of the briquette machine, and the roller skin is also a vulnerable part of the briquette machine. Therefore, before making a purchase, it is important to carefully check the roller skin of the briquette machine, which can not only ensure the quality of the briquetting equipment but also reduce the equipment cost and improve the economic benefits.

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.

When we buy briquetting equipment, we should not only consider the quality of briquette machine itself, but also consider the cost expenditure in the production process, such as labor cost, site cost, electricity cost, adhesive use and other expenses. Most of them are electricity charges, because the equipment is driven by the motor to work. Therefore, customers pay great attention to the parameters such as motor model, power and power consumption.

The high-pressure briquette machine produced by Luoyang Kaizheng is mainly used for making briquettes of nonferrous and ferrous metal ore powder quickly, directly entering the furnace for smelting, and increasing the added value. All waste materials or auxiliary materials in the metallurgical industry need to be put on the furnace, which needs to be completed by a briquetting machine. For example dust removal ash, pool mud, oxide scale, steel slag, iron concentrate powder, aluminum ash powder, silicon manganese ore powder, and so on. Various powders (such as magnesia, bauxite, dolomite, iron powder, etc.) can be made into spherical billets with high density by forced pressurization and preloading spiral precision processing, which are widely used in metallurgy, chemical industry, coal, and refractory industries.

The quality of the briquetting machine determines the ball rate and strength of the briquettes pressed out by the machine, which is the focus of the vast number of users. There are three standards to judge the overall performance of the briquette machine, which are: briquetting pressure, briquette strength, and briquette hardness.

Since the 1980s, with the deepening research of material crushing mechanism and analytical methods, two crushing methods, such as impact crushing and press grinding, have appeared in mechanical force crushing, and various new grinding equipment developed from this has developed rapidly.

The briquetting machine is a kind of equipment for pressing powdery materials into shapes. The briquette machine has a wide range of uses, which can fully press various pulverized coal (coking coal, lignite, caking coal, anthracite, etc.), mineral powder, dry powder, slag, and other powdery materials. There are many types of briquette machine, and the power is also different. When choosing, it should be decided according to the output required by customers.

The roller press must be full of material operation, between the two rollers must ensure full of material, can not be interrupted. Therefore, it is necessary to set a weighing bin with a steady flow at the upper part of the inlet of the roller press. The capacity design of the weighing bin should not be too small, otherwise, the buffer room is too small, which will affect the normal operation of the roller press and cause great fluctuation of the quality of the cake after rolling. In addition, it is necessary to control the material level of the weighing bin.

In addition to the high-pressure briquette machine itself fault, installation and debugging of the fault encountered by external equipment are mostly caused.
