(EN) Method for carrying out continuous mixing and preparation processes by means of special ratios of generated surfaces and free volumes or the inner and outer diameters of endless screws
(ZH) 利用外壳面积和自由体积或螺杆内径和外径的特定比例来实施连续混合和加工过程的方法
Abrégé
(EN)
The invention relates to a method wherein synthetic materials and elastomers (e.g. PET or rubber) can be carefully processed with throughput amounts which are as high as possible in order to improve the quality of the final product and increase the cost-effectiveness of the entire process. According to the invention, process tasks such as mixing, cooling/heating (heat exchange) and de-gasing (exchange of materials) can be carried out simultaneously and with greater efficiency.
