A mechanical stabilization mixer used in road infrastructure preparation plants includes a mixer body keeping all structure together, at least two shafts in rotating structure inside the mixer body and a reducer providing driving to the shafts. The mixing arms and mixing palettes of adequate and specially designed number in a manner directing material to the output mouth located in the centre while mixing material to be mixed homogenously and effectively. A material inlet primary mouth and material inlet second mouth are provided facing each other wherein material to be mixed is taken into the mixer body and the outlet mouth located in the centre.

A portable mixer that has a first auger, a second auger, a motor, a material loading location, where material may be loaded into the mixer, and a dispensing conduit. The motor powers both the first auger and second auger. Further, the second auger may rotate in a first rotational direction and a second rotational direction and the second auger substantially prevents material from exiting a dispensing conduit when the second auger rotates in the first rotational direction and the second auger distributes material through the dispensing conduit when the second auger rotates in the second rotational direction.

A vibration device for a mixing machine, comprising a vibration transmission device (1), a transmission shaft (5), bearings I (7), a bearing seat I (6), a bearing II (11), a bearing seat II (10), and a mixing shaft (13); the transmission shaft (5) is arranged so as to pass through the bearing seat I (6), and is supported in the bearing seat I (6) by means of at least two bearings I (7); one end of the transmission shaft (5) is connected to the vibration transmission device (1), and the other end of the transmission shaft (5) is fixedly connected to the bearing seat II (10); the bearing seat II (10) is connected to a shaft head at one end of the mixing shaft (13) by means of the bearing II (11); the rotational center line of the transmission shaft (5) is arranged so as to be offset from the outer raceway axis of the bearing II (11). The present vibration device for a mixing machine has the following advantages: simple structure, good vibration function and effect, and high reliability.

A mobile twin shaft mixer is disclosed herein, as well as methods of using the same. A benefit to the mobile twin shaft mixer can be a compact, lightweight, high capacity twin shaft mixer useful for mixing, proportioning, and transporting construction materials in mobile operations. A benefit to the methods of use of the mobile twin shaft mixer can be the supply of modern construction materials to the delivery location at the point of installation.

An apparatus for inserting and removing a mixer rotor pin includes at least one rotor pin with a transverse bore, as well as a rod dimensioned for slidably engaging the transverse bore. The apparatus also includes a mixer rotor pin insertion and removal tool having a tool body. A bottom of the tool has a slot for selectively engaging the aforementioned rod upon insertion of the rod into the transverse bore, and a top of the tool has a non-circular socket for accommodating a driver tool.
