Benefits of rubber paddles

As a SoRoTo mixer is highly versatile and can be used to mix several different materials, including concrete, resin bound gravel, screen, tile adhesives and render, it’s important that you use paddles which are appropriate for the job.

Manufacturer guidance suggests to use rubber paddles when mixing materials which contains aggregates larger than 8mm. This helps to reduce strain on the motor and gearbox, as well as preventing from becoming jammed should a piece of aggregate stick between the paddle and the drum.

Rubber blades should be using for mixing aggregates of more than 8mm.
The SoRoTo 100L can be fitted with rubber paddles which can make the mixer more long-lasting.

How to choose the right mixing paddle

With a SoRoTo machine, paddles and mixing arms can be ordered individually or as a set, optionally with or without the cross-joint which sits on the driveshaft. It’s not usually necessary to replace your cross-joint unless it is damaged.

It is important when buying replacement paddles to select the correct part as replacing with the incorrect part may cause inconsistent mixing and even machine fatigue or failure. To help with identifying the right paddle or arm, we have included exploded diagrams on our spare parts page. Simply visit the SoRoTo Mixers spare parts page, select your desired mixer and you will see the table and exploded diagram to help you.
