Haoxing grinding pump is a key equipment for the production of food, chemical, pharmaceutical, and new materials. In particular, this article focuses on the ultrafine refinement and homogenization of lubricating grease through mechanical shearing and grinding in the production of lubricating grease. Its core function is to convert the coarse particle lubricating grease after high-temperature reaction into fine and uniform finished products.

1、 Working principle

Mechanical cutting and grinding mechanism

The motor drives the rotating teeth to rotate relative to the fixed teeth at high speed, with a speed of several thousand revolutions per minute.

Strong shear force, high-frequency impact force, and eddy current are generated through adjustable grinding disc gaps (usually 2-50 μ m).

Apply multiple physical effects such as dispersion, mixing, crushing, and rolling to materials.

workflow

Suction stage: High viscosity lubricating grease enters the grinding chamber by pressure or gravity through a colloid pump (screw pump, cam rotor pump).

Grinding stage: The material undergoes multi-stage (usually 3-4 stages) shearing and grinding between the stator and rotor.

Discharge stage: The processed lubricating grease is discharged through the discharge port, with a fineness of up to 1-50 microns.

Power transmission system

The motor reduces the speed to the working range through a reduction device.

Some models use planetary reducers combined with cam mechanisms to convert it into reciprocating motion of plunger rods.

2、 Core applications

Lubricating grease production process

Used for precision processing after high-temperature saponification reaction.

Resolve issues such as soap fiber aggregation and oil separation and stratification.

Typical process: reactor synthesis → colloid mill treatment → degassing → filtration → filling.

Performance improvement effect

Make the lubricating grease achieve a delicate and shiny appearance.

Improve consistency stability and shear resistance.

Enhance the fusion of base oil and soap.

Industry application characteristics

Petrochemical industry: Processing high-end products such as lithium based grease and composite lithium based grease.

Food and medicine: Made of sanitary grade stainless steel material, in compliance with CIP/SIP standards.

Special lubricant: suitable for materials with ultra-high viscosity ranging from 0 to 100000 cPs.

3、 Equipment characteristics

structural design

Multi stage fixed rotor assembly (3-4 stages of grinding and homogenization).

Modular grinding disc for easy maintenance and replacement.

Equipped with pumping capacity (lift 5-10 meters).

Material characteristics

The contact parts are made of SS316/304 stainless steel or hard alloy.

Wear resistant design extends service life.

Explosion proof configuration meets chemical safety requirements.

Operational Advantage

Can be cooled/insulated online.

Support continuous closed production.

A uniform particle size distribution can be obtained in one processing (Haoxing JM-W180AC/JM-W200AC/JM-W250AD has both hole effect and degassing function).

4、 Difference from traditional equipment

Characteristic: Lubricating grease grinding pump, ordinary lubricating oil pump

Working principle: Shear homogenization grinding mechanism, pressure conveying mechanism

Processing semi-solid high viscosity lubricating grease (0-100000 cPs) liquid lubricating oil for materials

Structural features: Multi stage grinding disc, strong torque design, gear/plunger structure

Output effect changes the physical state of the material (refined to 1-50 μ m), maintains the material state, and only changes the conveying position

Typical application: Lubricating grease post-treatment process, mechanical equipment lubrication system, oil supply
