What is the Differences Between Mixer Models

Monolithic Equipment Mfg. has made three models of the Monolithic Mixer. ML1, ML2, and ML3. Below are the differences of the three, and what makes them unique.


The ML1 was the first model mixer that we made, The defining difference between this one and the others is the White motor. This motor/gearbox combination drive was one of the first ones that we used, and it worked for a long time, but after a few years, it started to show some of its weaknesses.

When we first started to make mixers, the different skid-steers would generally have the same hydraulic output for the auxiliary fittings. But some of the latest skid-steers have jumped their hydraulic pressures in the auxiliary systems up to as much as double. So if you have a mixer that was designed to turn at 2000 psi and connect it to a 4000 psi machine, it can cause trouble, especially if you get a big rock caught in the mixer.

Higher pressures, and improved preformence is why we switched from the White motors, not to mention they are expensive and hard to find parts to repair it. That is why we are selling the Mixer Drive Assembly Kit, is to help people that have a broken White motor to upgrade to the newer model with a pressure control system. With this motor, gearbox and pressure relief valve combination, the torque is increased by about 20%.


The ML2 is the second model. It has the new mixer drive system that regulates the pressure from the skidsteer, and has more torque than the previous model. It had very few design changes from the first models, except an extra piece on the mixer paddles to help mix concrete a little more evenly.


The ML3 is our current model. During the transition from the ML2 to ML3 we switched metal shops. The new metal shop that makes them is using much better machines for cutting out the components, and the mixers are tighter and stronger than ever.

Perhaps the best thing that the new mixer features is bearing step out. We stepped out the bearing from the side of the mixer, thus moving it away from contact with the cement. The new mixer has a seal that is designed to let any leaking cement water to simply leak out the side, and leave the bearing untouched.

We still have the same drive system, since we have really come to love and trust the current one. Also the new mixer features a chute for the side release, a bar for holding up the grate for cleaning, and other small design changes that we made for better performance.
