What are the different types of liquid nitrogen generators?

　　Liquid nitrogen machine equipmentWhat are the types?

　　Liquid nitrogen machine equipment, also known as cryogenic trimming machines, is mainly used for manual deburring of acorn products. This type of liquid nitrogen machine equipment was widely used in Europe and Japan in the late 1970s, but has only been used domestically for nearly 10 years. Liquid nitrogen trimming machine, total size 10 square meters, types: horizontal ball liquid nitrogen trimming machine.

　　Liquid nitrogen machine equipmentWhat is the principle?

　　Acorn materials are all polymer materials, and different temperatures will be in different states, but from the perspective of state, the material is only a change in mechanical state. When the material is at a low temperature, the state will change, and when it returns to room temperature conditions, all performance will be restored.

　　The liquid nitrogen trimming machine utilizes the low-temperature freezing effect of liquid nitrogen to make the rubber material brittle. In this state, high-speed injection of high-polymer plastic particles hits the weaker parts of the product, removing burrs from high-quality rubber products and aluminum and zinc alloy products. The physical properties of rubber materials change with decreasing temperature, becoming hardened, brittle, and crystallized. As the temperature decreases, the rubber material begins to harden, and below the brittle temperature, it will not deform or be damaged. The physicochemical characteristics remain unchanged after returning to room temperature.

　　Liquid nitrogen machine equipmentWhat are the characteristics?

　　Features of liquid nitrogen machine equipment: High efficiency: Cryogenic trimming machines can process the equivalent of 80-100 skilled workers' trimming costs per day on average. Using liquid nitrogen trimming machines can greatly reduce trimming, management, raw material, and mold costs and save factory floor space and other production costs. High quality: The trimming machine can perfectly remove burrs from products according to production requirements, and can process special structures that cannot be processed manually, without causing damage to the products. Environmentally friendly: Cryogenic deburring uses a physical method, does not discharge waste, and does not pollute the environment.

　　Applications and application range of cryogenic treatment: Applicable products: automobiles, aerospace, computers, communications, home appliances, and other 3C industries. Applicable materials: magnesium alloy, aluminum alloy, zinc alloy, etc.

　　Currently, the most popular in the worldLiquid nitrogen machine equipmentis the vertical jet liquid nitrogen trimming machine. Others are horizontal ball liquid nitrogen trimming machines, but they are currently being gradually replaced by vertical jet liquid nitrogen trimming machines. Vertical liquid nitrogen trimming machines are distributed in factories in Chongqing, Nanjing, Dongguan, Suzhou, Tianjin, etc., in China.

　　Ordinary ultra-fine crushers are prone to high operating temperatures when crushing materials at room temperature, which is not conducive to the crushing processing of some temperature-sensitive materials. Liquid nitrogen cryogenic crushers can completely achieve the crushing processing of such materials. In addition, the process of using liquid nitrogen as a medium to crush materials to be processed is relatively safe and reliable, and some special materials that are difficult to crush are also easy to break after adding liquid nitrogen.

　　Of course, this type of equipment that uses liquid nitrogen as a medium for cryogenic crushing can be used as an ordinary crusher if liquid nitrogen is not used to process materials.
