Constant temperature cooling water system of rubber mixer
Rubber mixing machine is divided into two types: open and closed. The open machine is mainly used for rubber heat refining, tablet pressing, rubber breaking, plastic refining and mixing, etc. The open machine began to be used for production in 1826. The closed rubber mixing machine is mainly used for rubber plastic refining and mixing. It has one more chamber than the open rubber mixing machine. Since the invention of elliptical rotor closed-type rubber mixing machine in 1916, the closed-type rubber mixing machine has developed rapidly in the rubber industry, and other forms of rotor closed-type rubber mixing machine have appeared later. The mixing cycle of the modern closed mixer is 2.5 ~ 3 minutes, and the large capacity of the mixer chamber is 650 liters.
In industrial production, many processes are water cooling, so it is necessary to have a circulating cooling water cooling equipment to produce cooling water. The circulating water cooling system produced by Zhonggao Cooling source is a circulating cooling machine, which reduces the circulating water to low-temperature water below *** temperature through compression refrigeration. Also known as chiller, water cooler, etc.
In the operation of the mixer, the plastic is heated first, and the temperature is precisely controlled by the constant temperature chiller. In the later forming process, the cooling water is needed to provide the cooling source for shaping. Different types of thermostatic cooling machines are selected according to the output, heating power, circulating water flow and other data.
