Both colloid mill and homogenizer mixing pump can shear, emulsify, disperse, and mix materials, but in fact, colloid mill and homogenizer mixing pump are two kinds of equipment based on the principle, structure, and application.

Colloid mill is a kind of grinding equipment, suitable for materials with higher viscosity and larger particles. The working principle of the colloid mill is that the motor drives the rotor and the stator to rotate at a relatively high speed. When the processed material passes through the gap between the stator and the rotor, it is subjected to strong shearing force, frictional force, high-frequency oscillation and other physical effects. The material is effectively emulsified, dispersed and crushed to achieve the effect of fine crushing of the material.

Emulsification pump is a kind of emulsification equipment, which is suitable for materials with small particles. The working principle of the emulsification pump is that the material undergoes a series of processes such as strong shearing, impact and turbulence between the homogenizer rotor and the stator that rotate at a high speed, so that the material can withstand hundreds of thousands per minute in the narrow gap between the stator and the rotor. Times of hydraulic shear. The combined effects of centrifugal extrusion, impact and tearing can instantly evenly disperse and emulsify. After high-frequency cyclic reciprocation, high-quality products with no bubbles, fineness and stability are obtained.

From the above point of view, the difference between the two in terms of the refinement effect, the mixed homogeneous emulsification pump is better than the colloid mill. Generally, in many occasions, the colloid mill is used in the front of the emulsification pump or in the high In the case of viscosity, colloid mills are often used for refinement when there are many solid substances. Therefore, when choosing colloid mill and emulsification equipment, you still have to refer to your own production materials.

Bonve homogenizer mixing pump’s working chamber is composed of a total if 12 layers of three-stage rotor and stator. Proceed products are dispersed, refined and emulsified by the rotor and stator in stages. The pump is an high efficiency ultra-fine homogeneous pump with mixing, dispersion, breaking, dissolution, refinery, homogenization, emulsifying and transporting. The sealing of Bonve homogenizer mixing pump can be either double face or single face according to the properties of the processed materials. It also can have heating insulation or cooling device if required by the users.

Bonve homogenizer mixing pump is suitable for large and medium batch continuous online production or cyclic processing production process.

High shear homogenizing mixer will inevitably encounter some failures during use. At this time, it is necessary to find out the cause of the high shear homogenizing mixer failure through troubleshooting, and then find out the countermeasures based on the cause of the failure.

The following are some of the faults that may occur in the high shear homogenizing mixer. You can check according to the use of the high shear homogenizing mixer.

When the pump does not discharge or less capacity

1. Check whether the valve at inlet and outlet pipe open.

2. Whether the pipeline setting of the high shear homogenizing mixer is too complicated.

3. Whether the inlet and outlet pipelines of the pump are blocked.

4. The concentration and viscosity of the processed product will reduce the production efficiency of the high shear homogenizing mixer or not discharge the product. Solution: Add a feeding pump to the feed port of the mixer or dilute the product before entering the feed port of the mixer.

5. When the high shear homogenizing mixer is running, the reverse rotation occurs. At this time, it is necessary to immediately turn off the motor, check and adjust the power connection line of the motor. Solution: Adjust the connection line of the motor power supply.

When the pump makes an abnormal sound during use

Hard solid materials such as metal may be input into the cavity of the high shear homogenizer mixing pump, which should be used after cleaning up the debris. For example, if the hard solids deform or damage the main shaft, stator and other parts of the high shear homogenizer mixing pump, you need to replace the corresponding parts.

Leakage of the homogenizer mixing pump during use

1. Check if the sealing ring is damaged;

2. Check whether the sealing surface of the mixer is unevenly stressed and the mechanical seal is damaged. Solution: Replace the corresponding sealing parts.

If the high shear homogenizer mixing pump is improperly operated during use, it will easily shorten the service life of the pump. If there are any problems or malfunctions, you can directly contact Bonve customer service, and we will solve the problem for you immediately.

How to remove and install the homogenizer mixing pump when pump ship to the destination port? Below are the tips to install Bonve high shear mixer.

1. Pump sent to area other than China will be packed in plywood case.

2. Users are advised to check the packing list, instruction manual, certificate of qualification, and other accessories attached after opening the wooden case.

3. Pump can be delivered to the installation site when the sealing bags at the inlet and outlet remain intact.

4. In hoisting, the hoist links at the pump body and the motor are available for use. If possible, users is better to carry the pumps with forklift trucks, handle with care.

5.The foundation of pump installation should have a horizontal plane. In line with the installation dimensions, four basic holes should be scooped first. Then ground screws are to be put into the holes for cement casting. When the cement is dry, use sizing block to adjust the chassis and make it horizontal. Lastly, screw up the ground bolts.

6. Pipe linking the pump should have supports respectively, which should not be the pump body.

7. To avoid damage to the pump's motor, install an overload current protection device during installation.

8. When the pump is installed, there should be a filter set ahead of the pump inlet. The filter screen should be 20 meshes or greater.

9. In installation, at pump inlet should be fixed a gauge valve for convenience of damaged meters replacement.

10. After the pump is installed, mark the ground connection point at the motor and make it connect the earth in accordance with the national safety standard.

11. If the pump is mobile type, hose should be used as at the inlet and outlet of the pump. In this case, valve and manometer are not necessary. The pump can only be pulled on level ground as four wheels (two of them are wheels) are fixed below the base plate. In case of too steep slope or a sharp turn, particular care should be taken to prevent any off-balance or sliding.
