The strength of the shearing effect of the vacuum emulsifying machine directly affects the fineness after all. After analysis, it is mainly related to the sharpness of the blade, the hardness, the gap of the rotating stator, the relative movement speed of the two cutting edges and the particle size allowed to pass. Under normal circumstances, the sharpness of the blade, the hardness, the gap of the rotating stator and the particle size allowed to pass are basically fixed or not to be changed, so the relative movement speed of the most influential factor, this is manifested by the circumferential linear velocity of the rotor, which is high, the density of the cuts or impacts on the radially active fluid is high, and therefore the thinning effect is strong, and vice versa. But the line speed is not the bigger the better,

Under normal circumstances, the sharpness of the blade, hardness, rotation stator gap and the particle size allowed to pass are basically fixed or do not want to change, so the relative movement speed of the blade is the most influential factor, this is manifested by the circumferential linear velocity of the rotor, which is high, the density of the cuts or impacts on the radially active fluid is high, and therefore the thinning effect is strong, and vice versa. However, the line speed is not the greater the better, when reaching a very high value, there is a tendency to constitute a blocking activity, so the flow becomes very small, and the heat is very high, some materials will in turn gather, so that the result is not ambitious.

So is the stirring speed we usually talk about the shearing speed?? The speed is divided into angular velocity and linear velocity. The shear velocity of course refers to the linear velocity. Linear velocity = angular velocity × diameter × π, so why is it used for industrial productionvacuum emulsifying machineThe speed is generally only2900rpm or 1440rpm, while the laboratoryvacuum emulsifying machineSpeed hasThe height of 12000rpm or 280000rpm is to consider the element of diameter, so that the shearing linear speed of the two is close, and the effect is close after all.

From another point of view, the laboratory equipment structure is smart, so the physical scale of the stator is small, and the diameter is bound to be small. In order to make up for the negative influence of the small diameter on the linear velocity, the angular velocity of the rotor must be increased, thus forming the test instrument."High speed. As can be seen from the above,vacuum emulsifying machineThe speed is to be considered in conjunction with the actual throughput, but at the current level of processing and production economy,Below 18.5KW, 2900rpm of a 2-pole motor is often selected, while 22KW to 55KW are generally 1450rpm of a 4-pole motor. If it exceeds 75KW, 960rpm of a 6-pole motor can be considered.
