Cement Mixer Review

This tool works great but the assembly instructions are lacking. The assembly is not hard but there are a lot of parts and figuring out how everything goes together is not fully explained in the instructions.

A few things to understand during assembly. Each bolt comes with one washer and one nut. The nuts have built-in self-locking washers. So when assembling put the washer on the bolt and the bolt through the hole then the nut on.

The instructions call to use gasket sealer on the bottom side of the gasket to hold it in place while you line up the top half of the drum. I did not do that because it’s quite messy and a cement mixer does not need gasket sealer.

The drum has an arrow sticker on the top and bottom half of the drum to show you where to join the drum halves so the mixing blades can be bolted on. My stickers were not placed in the correct position and when I tried to bolt on the mixing blades it would not line up with the holes. I had to take the top drum off and move it to align the blade holes.

The mixing blades can be put on upsidedown and the instructions do not show this step. The blades have one end that comes to a point and one end that is square. The pointed end goes down and the squared end goes up. Also, the bolts that hold the mixing blades to the inside of the drum should be placed from the inside with the nut on the outside of the drum. This will prevent cement from drying on the threads and enable you to remove the bolts later if needed.

Mixing Cement

Once the mixer is assembled the only other warning we have is to put some water into the mixer before adding cement. If you put in the dry mix then add water it does not mix the bottom and you can end up with dry mix at the bottom.

This machine is very durable. We were able to find an owner that had his machine for 10 years and said it still working like new.

Design Criticism

Although it’s a well-designed tool, a few design changes would have made this machine stronger with minimal added weight and cost. Four legs instead of three would make it more stable. Full box leg extensions instead of U-beams would add strength to the legs.
