Given the current problem of limestone solid waste treatment in steel mills, two briquetting treatment techniques and methods are introduced. It is suitable for the recycling of limestone mud cake in steel mills to realize the recycling of dust and sludge generated in its production process.

Material mixing refers to the homogenization of one or more materials to reduce or eliminate the uneven distribution of particle size, density, temperature and plasticity. It is a common material processing method.

Different industries use different mixers​ due to different types, characteristics， using and subsequent treatment methods of raw materials. The selection of a suitable mixer for compound fertilizer production plays an important role in ensuring the smooth progress of production and the final quality of products. The editor will show you how to choose a suitable mixer for compound fertilizer manufacturers.

For cold-consolidated pellets, molasses can be used alone as a binder, some of which may need to be diluted during use and a certain temperature is required. Molasses can also be used as a binder together with other materials. For some pellets that need special use, molasses may also be used as the main raw material to add other materials to prepare a binder with composite properties.

The mixing of high viscosity materials is often encountered in industrial production, and the mixing efficiency and mixing effect directly affect the quality and yield of finished products. The judgment of the mixing endpoint in the mixing time determination is the key, and different researchers have different methods to judge the mixing endpoint, and its accuracy varies.

In this paper, the effect of double-quenching on the surface hardness and heat treatment deformation of the roller skins was investigated using 9Cr2Mo steel roller skins for briquette machine, and the parameters of the double-quenching process were determined. The results show that by using the double-quenching method, the outer surface of the roller skin forms a hardness gradient distribution with high hardness in the middle and low hardness at the edges, and the heat treatment deformation of the roller skin is reduced and the service life is significantly improved.

High viscosity self-cleaning mixing equipment is mainly used in the field of adhesive substances, cosmetic products, lubricants, pigments, resins, rubber and plastic auxiliary substances, emulsions, industrial dyes and other chemical products, in these areas it has played its strengths with its unique features, so that the prospects are very good. High viscosity mixer is a collection of dispersion, stirring and mixing as one of the multifunctional and efficient equipment, more and more enterprises, researchers love. So specifically how is the high viscosity mixer used in the paint industry?

Extrusion molding process is the polymer processing field in the production of the most varieties, the most variation, high productivity, adaptability, wide range of uses, the proportion of the production of the molding process method. Extrusion molding is to make the polymer melt (or viscous fluid) in the extruder screw under the action of extrusion through a certain shape of the mouth die molding, the product is a continuous profile with a constant section shape.

There are many kinds of rubber products, but the production process is basically the same. The basic process of rubber products with general solid rubber - raw rubber as raw material includes: plasticizing, mixing, calendering, pressing, forming, vulcanization six basic processes.

There are different types of horizontal mixers, each model has its own structure point, for some of the applications in the connected industries is some places are similar, but also to a certain extent to be divided, there are some differences, the following introduces the commonly used several mixer models and structural properties.
