The difference between an open mixer and a mixer

First of all, from the structure point of view, the open mill generally works by the shear force generated by two relatively running but different rotational speeds of the roller, the mixing chamber volume is small, and the mixing efficiency is low. The mixer uses the regular contraction of space generated by the relative movement of the internal designed blade to generate shear force, without manual operation, saving labor, and the volume of the mixing chamber is also larger than that of the open mixer, and the mixing efficiency is greatly improved.

Secondly, from the price point of view, the open mill structure is simple and low cost, while the mixer structure is complex, and the production and research and development cost is high, so the price is relatively expensive. From hundreds of thousands of domestic equipment to Japan and other foreign imports of more than 1 million mixer have.

Again from the point of view of labor intensity, the degree of automation of the opening mill is low, the need for special personnel to assist the machine work, the labor intensity is large, and the degree of mechanization of the mixing machine is high, only a small amount of manual operation (such as feeding and unloading, etc.) the machine can work by itself, the labor intensity is small, and can be matched with automation equipment to achieve automatic feeding and taking.

Finally, from the perspective of environmental protection, there will be dust flying, material waste and other phenomena in the working process of the smelting machine, polluting the environment and endangering the health of workers; The mixer is a good way to avoid this problem, which is conducive to environmental protection.

In addition, the mixer compared to the open mixer, there are many advantages, here is not to go into details.

The mixer is a kind of high strength interstitial mixing equipment developed on the basis of the open mixer. Therefore, the emergence of the mixer is an important achievement of rubber machinery, and it is still a typical important equipment for plasticizing and mixing, and it is still being continuously developed and improved. At the same time, a number of other technologies can be applied to the mixer, such as vacuum mixer.

The vacuum mixer is a kind of mixing equipment with a vacuum device, which is specialized in mixing materials that are easy to react chemically with air components at high temperatures, which is the product of the specialized development of the mixer.

At present, the price of the mixer is relatively expensive, but I believe that with the continuous maturity of the mixer technology, as well as the improvement of people's requirements for mixing quality and efficiency, the price will become more acceptable, and this equipment will gradually replace the old open mixer and become the main force of mixing equipment.
