Information
Open mill is the abbreviation of open rubber mill. A rubber mill with exposed rollers used in rubber factories to prepare plastic compounds, compound rubbers, or stop hot-melting.
 
After weighing the amount of mixing rubber and vulcanizing agent, the next thing to do is to add a vulcanizing agent. It is recommended to complete the following steps.
1. First, clean the hygiene of the open mill to ensure its cleanliness to prevent mixing with other impurities. Then adjust the roll distance of the open mill to a minimum, put the compounded rubber into the open mill and stop the thin pass. After the thin pass is completed, the roll distance of the open mill is appropriately enlarged, so that the compounded rubber is evenly wrapped on the roll. The external temperature of the compound should be around 80oC.
2. After adjusting the roller distance and properly passing cooling water, the temperature of the compounded rubber is controlled to about 60 ~ 80 ° C. At this time, the vulcanizing agent is put into the compounded rubber at the beginning.
Need to pay attention to the vulcanizing agent in the open mill:
a. The vulcanizing agent should be evenly distributed into the compounded rubber instead of being concentrated in one center.
b. The delivery speed cannot be too fast. With a fast feeding speed, the vulcanizing agent easily falls to the bottom, and it is not easy to disperse into the mixing rubber, which will affect the performance of the mixing rubber.
c. Put the vulcanizing agent falling under the roller into the compounding rubber.

Rubber machinery-closed rubber mixer
Rubber Rubber machinery-closed rubber mixer
Time of issue : 2019-11-12 18:43:00
It is mainly used for plasticizing and mixing of rubber. It has one more mixing chamber than an open mixer (Figure 1). After the raw rubber and compounding agent are loaded into the mixing chamber from the feeding hopper, the material door is closed, and the upper plug of the material pressing device is pressed down, and the two rotors in the mixing chamber are rotated at different or the same speed. The loaded rubber is subjected to occasional stirring, rolling and kneading between the rotors, the rotor and the mixing chamber, resulting in oxidative chain breaks and increased plasticity. At the same time, the rubber material is dispersed and uniformly mixed due to the shearing effect, so as to achieve the purpose of making rubber. Since the invention of the elliptical rotor closed rubber mixer in 1916, the closed rubber mixer has been rapidly developed in the rubber industry, and then other types of closed rubber mixers have been presented. Modern closed mixers have a mixing cycle of 2.5 to 3 minutes, and the maximum capacity of the mixing chamber is 650 liters.

Uses: Mainly used for kneading and refining of recycled rubber. Features: The roller adopts alloy cold hard cast iron, the surface is hard and wear-resistant, the front and rear rollers are smooth rollers, and the inner cavity is processed to make the roller surface temperature uniform. Protect major parts from damage due to overload. The machine is equipped with an emergency brake. When an emergency occurs, the lever is pulled, and the machine is immediately braked, which is safe and reliable. The roller distance is adjusted by manual distance adjustment, which is convenient to operate. Take off the roll
