Main Classification Of Mixer

Classification by operation mode

(1) according to the operation mode, there are two types: circular operation type and continuous operation type.

The three processes of circular feeding, mixing and unloading are carried out at a certain time interval, that is, mixing by parts.

Because all kinds of materials are accurately weighed, the mixing quality is good. This type of operation is mostly used.

The above three processes of continuous operation are carried out continuously in a long cylinder. Although its productivity is higher than that of circular operation, the mixing quality is poor because the mix proportion and mixing time of each material are difficult to control. Use less.

Classification by mixing method

(2) there are two kinds of mixing methods: self falling mixing and forced mixing.

The self falling mixer is to put the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then drop it freely by self weight. Do this again and again until you mix well. This mixer generally mixes plastic and semi-plastic concrete.

The forced mixer is that the mixing drum does not move, and the forced mixing is carried out by the blades arranged on the rotating shaft in the drum. The mixer has good mixing quality and high production efficiency; However, the power consumption is large and the blade wear is fast. It is generally suitable for mixing dry and hard concrete.

Classification by device mode

(3) according to the device mode, there are fixed type and mobile type.

The fixed mixer is installed on the prepared foundation, and the whole machine cannot be moved. It has large volume and high production efficiency. It is mostly used in mixing plant or mixing plant.

The mobile mixer itself has running wheels, small volume and light weight, so it has good motor performance. It is applied to small and medium-sized temporary works.

Classification by discharging method

(4) there are two discharging methods: tipping type and non tipping type.

The tipping type relies on the mixing drum to dump the material, while the non tipping type relies on the mixing drum to reverse the unloading.

Shape classification

(5) according to different shapes of mixing drum, there are five types: pear type, drum type, double cone type, disc vertical shaft type and circular groove horizontal shaft type. The first three are self falling stirring; The latter two are forced mixing, which are rarely used in China.

Classification by mixing capacity

(6) according to the mixing capacity, there are large (discharge capacity 1000 ~ 3000l), medium (discharge capacity 300 ~ 500L) and small (discharge capacity 50 ~ 250L).
