Double Roll Mill Structure

The twin-roll mill is an important equipment that organically combines the processes of raw rubber and rubber mixing. The two-roll mill is used to convey raw rubber and rubber, and heat the raw rubber and rubber in a relatively unstable state, thereby increasing its vulcanization speed and promoting mixing. The main equipments are two-roll mill frame, two-roll mill transmission mechanism and two-roll mill heating system.

Introduction to the main structure and usage of the tablet press

The tablet press machine is mainly used for the tablet process research in the pharmaceutical industry. It is an automatic continuous production equipment for pressing granules into round, special-shaped and tablets with text, symbols and graphics with a diameter of no more than 13mm. The punches and dies of the tablet press are under a lot of pressure during the tablet pressing process. They are usually made of bearing steel and heat-treated to increase their hardness. There are many types of punches, and the shape of the punch depends on the desired shape of the tablet. According to the shape of the die structure, it can be divided into circular and special-shaped; the shape of the punch section is flat, hypotenuse, shallow concave, deep concave and comprehensive. Plane and hypotenuse punches are used for pressing flat cylindrical tablets, shallow concave punches are used for pressing biconvex tablets, deep concave punches are mainly used for pressing the core of coated tablets, and composite punches are mainly used for pressing Shaped sheet. In order to facilitate the identification and taking of medicines, the name of the medicine, dosage and vertical and horizontal lines can also be engraved on the end face of the die. To compress tablets of different doses, dies of suitable size should be selected.

Mixing and feeding order of internal mixer and its influence on rubber compound

Internal mixer mixing is carried out in a fast, high temperature and high pressure environment, with large glue loading capacity, short mixing time and high production efficiency. The mixing effect of the internal mixer is affected by many factors, in addition to the order of feeding, it is also related to the mixing temperature, glue capacity, rotor speed, mixing time and other factors. Let me share with you the mixing and feeding sequence of the internal mixer and its influence on the rubber compound.

Factors Affecting Mixing Effect of Internal Mixer

Compared with open mixer mixing, internal mixer mixing has the advantages of short mixing time, high efficiency, high degree of mechanization and automation, good rubber quality, low labor intensity, safe operation, small loss of flying medicine, and good environmental sanitation conditions, etc. Advantages, but the heat dissipation in the mixing chamber of the internal mixer is difficult, the mixing temperature is high and difficult to control, which limits the temperature-sensitive rubber materials, and is not suitable for light-colored rubber materials and rubber materials with frequent variety changes. In addition, the internal mixer needs to be equipped with a corresponding unloading device for mixing.

Three ways to control the temperature of the rubber mixer to solve the problem of heating and cooling?

The rubber mixing machine is used in the field of rubber and plastic processing, and it has been increasing in recent years. In plastic product factories, people are used to calling it a two-roller machine. On the calender production line, the rubber mixer is before the calender and after the mixer, and its function is to mix and plasticize the uniformly mixed raw materials, so as to provide a more uniform melting material for the calender calendered plastic products. When producing cable material, the milling machine can directly refine and mold the powdered material mixed according to the formula into a molten material, and then compression molded into a sheet-like belt, so that the pelletizer can be cut into granules. On the production line of floor leather, it can directly provide the base coating with uniform mixing and plasticization for the cloth base leather.
