The mixing mill, also known as the double-roll mixing mill, is one of the indispensable equipment in the rubber and plastics industry. It uses two relatively rotating rollers to shear, extrude and rub the materials, thereby achieving the process of mixing, plasticizing and dispersing the materials. It can be called the "alchemist" of the rubber and plastics industry.

Working Principle

The open mixing mill is an open intermittent mixing device for plastic materials, which consists of

two parallel rollers with an adjustable gap between rollers. Its main function is to mix and plasticize the uniformly mixed raw materials, and provide the calender with uniformly mixed and plasticized molten materials. In the process of rubber mixing, the open mixing mill mainly relies on the extrusion and shearing effect of the two relatively rotating rollers on the rubber. After multiple kneading and mixing, the mixing process is also accompanied by chemical reactions, which break the macromolecular chains inside the rubber, so that the various components inside the rubber are mixed and dispersed evenly, and finally achieve the purpose of rubber mixing.

The open mill is widely used in the following fields:

Open mixing mill is widely used in rubber, plastic and its products, polyolefin, polyvinyl chloride, film, coil, profile production and polymer blending, pigment, masterbatch, stabilizer and other industries, mainly used in the following aspects:

Rubber and its products:plasticizing and mixing of natural rubber and synthetic rubber,as well as the production of rubber products such as tires,hoses and tapes.

Plastics and their products:plasticizing,mixing and sheeting of thermoplastics,as well as the production of plastic films,sheets,pipes and other products.

Polymer blending:blending and modification of different types of polymers to improve material properties.

Dispersion of additives such as pigments,masterbatches and stabilizers:improve the dispersibility of additives in the matrix and improve product quality.

The open mill has the following advantages:

Efficient mixing:unique roller design and powerful drive system ensure that the materials are fully mixed and improve production efficiency.

Accurate temperature control:advanced temperature control system accurately controls the roller temperature to meet the process requirements of different materials.

Easy to operate:Humanized operation interface,easy to use,reducing the difficulty of operation.

Stable and reliable:High-quality materials and exquisite manufacturing technology ensure long-term stable operation of the equipment and reduce maintenance costs.

The future development trend of open mill:

With the continuous development of the rubber and plastics industry, open mills are also constantly updated. The future development trend is mainly reflected in the following aspects:

• Large-scale: In order to meet the needs of large-scale production, the specifications and capacity of open mills will continue to increase.
• Intelligent: The application of automation and intelligent technology will improve the production efficiency and product quality of open mills.
• Energy saving and environmental protection: Energy-saving and environmentally friendly open mills will become the mainstream of future development.
