According to the structure of the mixing drum, it is divided into pear type, drum type, double cone, disc vertical shaft type and circular groove horizontal shaft type.
According to the operating power, it can be divided into electric concrete mixer and diesel concrete mixer.
Types of Concrete Mixers
Self-falling Concrete Mixer
The self-falling concrete mixer places the mixture in a rotating mixing drum. As the mixing drum rotates, the blades in the drum lift the mixture to a certain height, and then it falls freely by its own weight. Repeat this over and over again until evenly mixed. This mixer generally mixes plastic and semi-plastic concrete.
Self-falling mixer can be divided into drum-shaped, conical reversing discharge, conical tipping discharge and other types according to the structure of the mixing drum. It consists of a mixing drum, a hydraulic feeding mechanism, a mixing drum friction wheel drive system, a water pump-time relay water distribution system and a single-axis towed chassis.
The self-falling type has the characteristics of simple structure, low energy consumption, little wear, long life, and simple use and maintenance. However, the rotating speed of the drum is limited by the critical speed, and the production efficiency is low. It is only suitable for mixing plastic concrete with general aggregates.
Compulsory Concrete Mixer
For a compulsory concrete mixer, the mixing drum doesn’t move, but the mixing is forced by blades evenly placed on the rotating shaft inside the drum. This kind of mixer has good mixing quality and high production efficiency, but it consumes a lot of power and the blades wear out quickly. It is particularly suitable for mixing dry hard concrete and lightweight aggregate concrete.
The compulsory mixer for sale in our company mainly solves the problem that the water amount of the twin-shaft concrete mixer is difficult to control and the mixing force is small. The machine includes a planetary mixing mechanism, an eddy current mixing mechanism, a mixing drum, a discharging mechanism, a mixing frame and a bottom frame. There is an eddy current mixer in the center of the mixing drum. There are two planets symmetrically arranged on both sides of the eddy current mixer frame. The two planetary mixers rotate relative to each other, and the eddy current mixer and the mixing drum rotate in opposite directions. The machine has strong stirring power and solves problems such as agglomeration and bunkering.
Horizontal Concrete Mixer
Horizontal concrete mixer is a common concrete mixer. Its main feature is that it occupies a small area and is suitable for occasions with limited space. It has a compact structure, easy operation and good mixing effect. Horizontal concrete mixers are suitable for producing precast concrete, concrete pipes, reinforced concrete and other materials.
Vertical Concrete Mixer
The vertical concrete mixer is a vertically placed concrete mixer. The equipment has a compact structure and a small footprint, making it suitable for situations with limited space. The vertical concrete mixer has good mixing effect and is suitable for producing high-strength concrete, bridges, water conservancy projects and other materials.
Mobile concrete mixer
Mobile type concrete mixers can be divided into traction and self-propelled mixers, which are used to mix and transport plastic concrete.
The mobile concrete mixer is suitable for occasions that require frequent transfers. Its main feature is its mobility, which makes it easy to work in different construction sites. Mobile concrete mixers are suitable for on-site construction, road and bridge construction and other materials.
Non-tilting mixer
The axis of rotation of a non-tilting mixer is fixed. The mixing drum is drum-shaped or double-conical, with an opening at each end. One end is for loading, and the other end is the discharge port.
Tilting type mixer
Tilting concrete mixers can be divided into single cone and double cone. A single conical mixer has only one opening for loading and unloading materials. It is characterized by high working volume utilization, rapid and clean discharge, and can mix concrete with large aggregate particle size.
Periodic Concrete Mixer
The three processes of feeding, mixing and unloading in the cyclic operation type are carried out periodically at certain time intervals, that is, mixing by portion. Since the various materials being mixed are accurately weighed, the mixing quality is good. Currently this type of operation is mostly used.
Continuous concrete mixer
The three processes of continuous operation of feeding, mixing and unloading are carried out continuously in a longer cylinder. Although its productivity is higher than that of the cyclic operation method, the mixing ratio of each material and the mixing time are difficult to control, so the mixing quality is poor.
The periodic type can accurately control the proportion of concrete and ensure the mixing quality. Continuous type have higher productivity.
Twin Shaft Concrete Mixer
The twin-shaft mixer includes first and second mixing shafts parallel to each other, mixing blades and a horizontal mixing barrel. The stirring blades extend from the first and second stirring shafts to all sides, and are arranged equidistantly in the axial direction and differ from each other by a fixed angle clockwise or counterclockwise in the circumferential direction, so that the stirring blades on the first and second stirring shafts are arranged in a spiral shape with opposite directions of rotation. The first and second stirring shafts rotate synchronously with each other and their blades are staggered through a plane defined by the axes of the first and second stirring shafts. There is a feed port at the top of one end of the mixing barrel, and a discharge port at the bottom of the other end. With this structure, the mixing blades of the mixer discharge the dry mortar from the inlet port to the outlet port while stirring the dry mortar, thereby achieving continuous production and effectively improving production efficiency.
Choose the suitable model of concrete mixers
- Choose mobile or fixed type. Customers can choose suitable specifications according to their own needs.
- Production capacity. The production capacity of a concrete mixer refers to the amount of concrete that can be produced per hour, generally between 10m³/h and 90m³/h. Customers can choose the corresponding production capacity according to project needs.
- Mixing drum volume. The volume of the mixing drum refers to the maximum amount of concrete that the concrete mixer can accommodate when mixing. It is generally between 0.25m³ and 2m³. Users can choose the corresponding volume according to their own needs. Concrete mixer specifications should be selected based on project needs, mixing volume, mixing time and other factors.
- Motor power. Motor power refers to the motor power equipped with the concrete mixer, generally between 5.5kwand 90kw. The power of the mixer directly affects its mixing efficiency. Generally, a mixer with a power slightly greater than the actual required mixing power is selected. Customers can select the corresponding motor power according to the corresponding production capacity and mixing drum volume.
- Overall machine weight. The weight of the whole machine refers to the weight of the concrete mixer, which is generally between 1t and 10t.
- Dimensions. The size of the concrete mixer is also one of the factors that users need to consider. The size will affect the transportation, storage and use of the mixer. Customers can choose the corresponding size according to their own needs.
