Rubber machinery-closed rubber mixer

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 and characteristics of open kneader

Release time : 2019-11--12 Clicks : 0
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
