Waste tire Mixing Mill/Refining Mixing Mill/Rubber Crusher Machine

Rubber kneader rubber mixer rubber mixing mill

.Rubber Kneader with complete sealed condition;

.National Patent for the dust-proof seal;

. ISO 9001-2000 Certification;

1.Rubber kneader with completely sealed condition,materials are mixed or plasticated under certain pressure,controllable temperature ,which makes high production effciency and obtains excellent quality. 

2.Spiral angle and over lapping length of the blades of the rotors are of reasonable design and make the materials to bedispersed uniformly. 

3.Surface where is contacted with the materials are all platedwith hard chromium and polished,which is corrosion-resistantand wear-resistant. 

4.Jacket construction is adopted in parts that surfaces contactwith materials to achieve excellent water-cooling or steamheating effect and fit in with the needs of plastics and rubberprocessing technology.

5.Feeding from back door on the frame (or a separate top door)is convenient for continuous process operation in aproduction line. The mixing chamber is able to turn forward by 140 aroud the frond rotors to discharge and is easy for changingpigments and cleaning the chamer.

6.Programmable logic controller (PLC) is adopted in theelectric-control system,which has reliable control function andalarm function,and interlock safety-protection function and itis procded with serial interface of net.

There are many speeds and speed ratios available, which can satisfy most customers' formula and processing requirements.

Frame, frame cap and base, looking very nice, are welded and treated by annealing for stress relieving.

Chilled alloy cast iron roll is abrasion resistant with long service life.

The speed reducer is the hard-tooth surface gear reducer of Class 6 precision, which has long service life and low noise.

Perfect emergency stop device can ensure the safety of personnel and equipment.

The seal structure with special design can eliminate the leaking phenomenon of lubricating oil.

Stock pan is easy to clean up with dislodging device.

Human nature designed operating system reduces labor intensity.

Modular structure offers various structures for customers' option.

The flexible design system can satisfy customers' special design requirements within the shortest time.

A load test running will be made to the assembled equipment in our company to save debugging time for customers.

The rolls are made of special cast iron.

The working surface of the roll is chill cast,forming a very hard and excellent wear-resistant shell.

The rolls can be supplied as casting, or as wholly machined ones,including  turning,grinding,drilling.keyway cutting,thread taping.etc. The working surface of the roll can be ground cylindrical or crowned.We are making groove rolls as well

We are using either the ordinary gravity pouring process or the centrifugal pouring process,or a combination of both processes.Customers are free to choose which process they prefer.

The centrifugal pouring process for big size rolls is a recently developed pouring process.The notable advantages of rolls made by centrifugal pouring process vs rolls made by ordinary gravity pouring process are:

1).The chill cast shell and the inner part of the roll can be poured separately. Thus different composition of iron for the shell and for the inner part can be chosen freely according to different requirements.

2).The thickness and the hardness of the chill cast shell can be controlled more precisely and uniformly.

3).The molten iron is condensed under the centrifugal force.The surface of the shell is free from porosity, sand hole, slag inclusion, or other casting defects.

4).When the roll is made by ordinary gravity pouring process, there is always a layer of mottled iron formed between the white iron(chill cast iron) and the gray cast iron. When drilled roll is used, this mottled cast iron layer always makes the drilling very dificule. When the roll is made by centrifugal pouring process, there is no mottled iron layer formed at all. The mottled iron layer problem no longer exists. The drilling can be done easily and precisely.

5).When proper materials are used and centrifugal pouring process is adopted. the hardness of the chill cast shell can hold as high as HS 74+/-2.The tensile strength of the roll can reach as high as 250 MPa. The working life of the roll made by centrifugal pouring process would be three to five times the working life of the rolls made by ordinary gravity pouring process.
