Use, structure and working principle of open mill
 
 
1. Structure (divided into two parts of transmission and host)
a. Transmission part: motor, driving gear, etc.
b. Main machine parts: Roller and its main components such as bearing, frame, beam, machine base, and distance adjustment installation, safety brake, roller temperature adjustment installation, smooth installation, etc.
 
2. Working principle: When the rubber material is added to two oppositely rotating rollers, depending on the speed, it is pulled between the two rollers under the effect of friction, and the cross section of the roller is reduced, causing the rubber material to be exposed to Fierce shearing and squeezing action, at the same time produce oxidative chain breaking, increase plasticity, so as to achieve the purpose of rubber (plasticizing).
 
3. Working performance: The working performance of different specifications of open mills is not the same. Our company's conventional BL-6175 open mills, temperature
The accuracy is ± 2.5 ℃, the distance between the rollers is 0.05 ~ 8mm, and the rubber mixing capacity is 50 ~ 3000g at one time. It can be used for pressing films, hot-melting, and rubber supply. Roller
The temperature can be adjusted according to the needs of the process. Generally, it should be between normal temperature and 300 ° C. The amount of rubber, the diameter of the roller, the length of the roller, the distance between the rolls, the speed of the speed, the speed of the rubber, the temperature of the rubber, the time of the rubber, the degree of operation technology, etc. directly affect the working performance.
 
4. Uses: The double-roller mill is mainly used for mixing, plasticizing, and extruding high-molecular polymers such as engineering plastics, modified plastics, and masterbatches.
It has the characteristics of average dispersion, plasticizing coloring, and filling modification. Suitable for laboratory experiments and quality control, teaching seminars and small-scale consumption.

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
