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.

Horizontal high intensity mixer is developed for the preparation of raw materials, solid waste treatment and other various process tasks, the current application working conditions are: the components vary greatly in the mixing of powder, such as iron concentrate powder and bentonite, there are powder and binder mixing, but also the mixing of semi-solid materials.

2. The advantages of horizontal mixer are mainly manifested as follows: wide range of application, less destructive to materials; high stability, long life; high loading rate, strong sealing; etc. The following article details several advantages, and how to choose a horizontal mixer according to these advantages, let's take a look together.

Extrusion granulation process is a very common technology at present, but if the operation is careless or there are other influencing factors, there will be a variety of extrusion problems, next we talk about the factors affecting the effect of extrusion:

Pulverized coal briquetting machine is a kind of equipment for pressing powdery materials into balls. It is mainly used for cold pressing pellets and refractories of pulverized coal, slime, medium coal, coke powder, coking coal and metallurgical powder. All powdery materials that need to be put into the furnace need a ball press to complete.
