Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, beneficiation, coal, water treatment and shipping sectors. Centrifuges are machines that use centrifugal force to separate the components of a mixture of liquid and solid particles or liquid and liquid. Centrifuges are mainly used to separate the solid particles in the suspension from the liquid; or to separate the two incompatible emulsions in the emulsion (for example, to separate cream from the milk); it can also be used to eliminate Liquids in wet solids, such as washing wet clothes with a washing machine; special overspeed tube separators can also separate gas mixtures of different densities; use different characteristics of different density or granularity of solid particles in the liquid, different settlement speed, some settlement Centrifuges can also classify solid particles by density or size.
The choice of centrifuge must be based on the size and concentration of the solid particles in the suspension (or emulsion), the density difference between the solid and the liquid (or both liquids), the viscosity of the liquid, and the characteristics of the filter residue (or sediment).
The difference between homemade centrifuges and imported centrifuges is not very large, and China has already embraced the core technology of centrifuges. The price difference between the centrifuges of the same grade is not very big, and the main difference is in performance and configuration.
The main difference is in terms of performance. Centrifuges with refrigeration are much more expensive than ordinary centrifuges. Some centrifuges also have heating functions. The more centrifuges the control program has, the higher the price. The larger difference is in the configuration, and sometimes the price of the attachment is higher than the price of the host. It is important to pay attention to the purchase, in addition to the host, the choice of rotor (number and type), plus the necessary centrifuge tubes, tube sets, special centrifuge bottles or blood bags, all of which add up to a complete centrifuge price.
Domestic centrifuges want to catch up with the pace of foreign products, we must develop advanced technology, make a fuss about the performance and configuration of equipment, continue to narrow the gap between the two, and gradually embark on the road to internationalization.
Milling machines have features with high precision, high working speed and stable performance in cavity on ISO IC card, telecom card and dual interface card.
While embedding machines are easy to be maintained and operated. They are used for chip punching and put different chips in the cavity, to realize IC card embedding process.
YUANMINGJIE technology creates full auto Milling And Embedding two in one machine, which combines functions of milling and embedding machines. Milling and Embedding two in one machine can not only make millings we need but also can test, punching and implant different model of chips in cavities.
