攪拌裝置的設計選型與攪拌作業目的緊密結合。在設計選型時首先要根據工藝對攪拌作業的目的和要求,確定攪拌器型式、電動機功率、攪拌速度，然后選擇減速機、機架、攪拌軸、軸封等各部件。
根據攪拌介質物料的物理特性，按照工藝條件和攪拌目的，選擇攪拌器型式。
按照所確定的攪拌器型式及攪拌器在攪拌過程中所產生的流動狀態，工藝對攪拌混合時間、沉降速度、分散度的控制要求確定電動機功率、攪拌速度、攪拌器直徑。
按照電動機功率、攪拌轉速及工藝條件，從減速機選型表中選擇確定減速機機型。
根據容器或池體尺寸確定攪拌器層數： 1） T殳按照池體（容器）高度/池體直徑（或長寬）比接近1:1,選擇1層攪拌器；2） 當池體（容器）高度/池體直徑（或長寬）比大于等于1.5:1,選擇2層攪拌器；3） 當池體（容器）高度/池體直徑（或長寬）比大于等于2.5:1,選擇3層攪拌器
攪拌流量、電機率的計算，這是非常重要的一步：一般是根據攪拌強度的需要來確定，采用計算軟件進行計算，具體計算時需輸入粘度值、密度、槳葉層數、轉速等參數。
液體攪拌機封密型式的選擇：1) 一般情況下，不考慮設置密封裝置；2) 有密封要求，但密封要求不太高的場合，優先選擇四氟盤根的填料箱密封；3) 嚴格密封要求的，可采用磁力傳動靜密封結構，即選用磁力傳動(驅動)攪拌機。
Choosing mixer models according to physical properties of mixing material, tech no logical conditi ons and mixing purposes.
Determining motor power, mixing speeds and mixer diameters according to determined mixer models, flow patterns during mixing and technical control requirements of mixing time, sedimentation velocity and dispersity.
Selecting determined speed reducer models from the speed reducer model table according to motor power, mixing speeds and technological conditions.
Determine the number of agitator layers according to the size of the container or pool:1)、Gen erally, accordi ng to the height of the pool body (con tainer) / the diameter of the pool body (or length and width) is close to 1:1, select a layer of mixer; 2)、When the cell body (container) height / cell body diameter (or length to width) ratio is greater than or equal to 1.5:1, select a 2-layer mixer;3)、When the cell body (container) height / cell body diameter (or length to width) ratio is greater than or equal to 2.5:1, select a 3-layer mixer
Calculation of mixing flow and motor power is a very important step:Generall, it is determined according to the need of strring intensity,ａnd calculation software is used for calculation. In the specific calculation, parameters such as viscosity value, density, number of blade layers, and rotation speed are input.
Selection of Seal Models of L iquid Mixers:1)、Under normal circumstances, it is not considered to set the sealing device;2)、Where there is sealing requirement, but the sealing requirements are not too high, the packing box sealing of PTFE packing is preferred;3) For the strict sealing requirements, the magnetic transmission static sealing structure can be used, that is, the magnetic drive (drive) mixer is selected.
