Brief Introduction and Working Principle of the Open Mill

• The machine mainly uses two rollers with a certain amount of heat and relative rotation movement for the mixing plastication of the raw materials used in the plastic products.
• The raw materials are added on the working surfaces of the two rollers in operation; due to the different revolving speeds of the two relatively rotated rollers, the temperature of the working surface is also slightly different; then the raw materials on the roller surface gradually become soft along with the increasing temperature due to the heat conduction and fiction effect of the roller, stick to the roller surface and rotate with the roller.
  
• When these raw materials enter into the gap on the working surface of two rollers, due to the small gap between the roller surfaces, and the revolving speeds on the two roller surfaces are different, the materials suffer from the strong extrusion, shear, and kneading action; due to the complex motion among the raw materials, the raw material produces a certain amount of friction heat in itself; in addition, the surface of the roller also has the conductive heat.
• Due to the combined action between these internal factors and external conditions, the raw materials on the roller become softened and in mixed plasticization and molten state; in addition, the operator will constantly stir up the raw materials among the rollers, so that the raw materials can be mixed and plasticized uniformly. At the moment, the raw materials can be delivered to the calendar and rolled into the products.

Xinhuaqing patented open mixing mill rubber machine

Maintain and repair various types of rubber machinery and equipment were the core business at the beginning of the company was set up, however the maintain and repair mixer and mixing mill was the most .So,engineers knew the defects very well on technology and application of mixer and open mixing mill.

Summing up one set of meticulous maintenance technology and method, interchanging with home and abroad experts, depending our own a large number maintenance experience, the technical innovations were made on the above two kinds of machines starting from the applicable and practical perspective.

Powder leakage and tilting system copper worm gear easy broken on rubber kneader,main reducer output shaft bearing easy broken and cause the malfunction of machine are quite often on open mixer,these are the main problems need to be solved.

After number of test running about improvement on these two kind of machines, all mentioned problems are throughly solved.

The comprehensive performance of the improved rubber kneader and open mixing mill are the best machines among similar products in the internal market and even in international market.

Absolutely,it is an technology innovation on rubber kneader and openmixing mill.

XinHuaQing Patented Technology	Old Technology
Based on the push back drive style,the stress direction of the output shaft support of the reducer have been changed. The output shaft is hard to loose, thus the service life of whole machine have been greatly extended.Consequently,the maintain cost are decreased	Based on the down stroke drive style , the output shaft is easy to loose, cause the teeth on big and small driving gears are mashing in partial,the shaft and the shell of the reducer are quite easy broken.Once the problem happend, it is hard to make the machine in the normal performance state.
XinHuaQing Innovated Technology	Old Technology
One big and small geared driving system was abandoned. Instead,the harden surface gear,rolling bearing consist of triple geared driving system are introduced,to ensure the service life of the machine are greatly extended.	One big and small geared driving system was abandoned,with the planetary geared reducer, the gears are vulnerable pieces,of course,the
