In the construction of asphalt pavement Road cold recycler machine, the milling rotor plays a very important role. The powerful power of the machine must be completed by the milling rotor. As asphalt pavements and roadbeds often have high strength and hardness, cold-recycled milling rotors are required to have working stability, high abrasion resistance, and replaceability of cutter teeth and tool magazines. This is completely different from road mixing rotors for mixing lime soil. , Similar to the requirements of the milling machine rotor. At present, most domestic manufacturers of Road cold recycler machines use welded tool magazine rotors. Such rotors can meet the requirements for the construction of low-strength asphalt lime soil subgrades, but they can meet the requirements of high-strength water-stable subgrades (crushed stones). (Subgrade) In Road cold recycler operations, welded tool magazines show great limitations, such as the tool magazine is not abrasion-resistant, and it is easy to drop tools. Such rotors can often only be used for about half a year, and even a project requires a large Change the magazine in batches. If the tool magazine is not replaced in a timely manner, due to the wear of the holes in the tool magazine where the cutter teeth are installed, it is easy to cause a large number of knife drops during construction. It is thrown away from the tool magazine, which will greatly increase the construction cost and make the cold regeneration construction impossible in severe cases. Since the tool magazine of this rotor is welding type, the welding work of cutting and welding on site is very large and it is difficult for the user to complete. In order to solve the tool magazine wear and eliminate the phenomenon of tool dropping, a heavy milling rotor with replaceable tool magazine must be used. The biggest difference between the heavy-duty rotor of the detachable tool magazine and the ordinary welded rotor is that a combination of a welded base and a detachable tool magazine is used. The frequently changed cutter teeth are installed on the detachable tool magazine. At the construction site, both the cutter teeth and the tool magazine can be easily removed and replaced. The base welded to the rotor is protected from the tool magazine and will not wear out for life without replacement.

The cold recycler uses a heavy-duty rotor with a removable tool magazine, which solves the problem of replacing the tool magazine on the spot by the user and avoids the phenomenon of abnormal tool dropping. Detachable tool magazine heavy-duty rotors are ideal milling rotors for Road cold recycler construction. They are standard equipment of imported models, but detachable tool magazine rotors are expensive. Domestic companies have not generally adopted this type of rotor due to cost reasons. Our company has been committed to the development and production of heavy-duty rotors for detachable tool magazines. After repeated tests and industrial application assessment for more than a year, the heavy-duty rotors for detachable tool magazines independently developed and produced by our company have been completely successful, regardless of manufacturing accuracy, The abrasion resistance and reliability of the rotor have met the design requirements, which are comparable to imported milling rotors. Even the rotor's running stability (dynamic balance) is stronger than imported rotors.

Ruima Heavy Industry is the only mainframe manufacturer in China that can design and manufacture heavy-duty rotors for detachable tool magazines, filling a gap in China. Other domestic milling machine and Road cold recycler machine manufacturers, if they want to use a removable tool magazine rotor, they cannot produce it themselves, they are all commissioned by foreign brand companies. The high cost and the production cycle of several months severely restrict our Road cold recycler. Machine development. .

The WR2300L and WR2300E pavement Road cold recycler machines produced by our company have all been equipped with the heavy-duty rotors of our detachable tool magazine designed and manufactured by our company. This kind of rotor has obvious advantages in the Road cold recycler construction of high-strength water-stable roadbeds. Praised by users.

Many domestic users have recognized the advantages of heavy-duty rotors for removable tool magazines, and have specified that they must be equipped with heavy-duty rotors for removable tool magazines when purchasing Cold recycler and road mixers.
