A mixer is a common industrial device used to mix, stir, or evenly mix many different materials. It has a wide range of applications in various industries, including chemical, food, medicine, building materials and other fields.
The working principle of the mixer is to mix different materials into the mixing chamber through the agitator or mixing device to achieve the effect of mixing evenly. Mixers can choose different types of agitators according to the nature and requirements of different materials, such as spiral agitators, blade agitators, etc.
Mixer is usually composed of main engine, motor, agitator, control system, etc. According to different mixing needs, the design and specifications of mixers will be different, for example, some mixers are suitable for solid to solid mixing, some are suitable for solid to liquid mixing or liquid to liquid mixing.
What Problems Does It Solve?
Side entry mixers are designed to solve mixing challenges in large storage tanks where sedimentation, phase separation, and poor circulation commonly occur.
They are widely used to:
Prevent sludge accumulation at tank bottom
Maintain liquid homogeneity in large storage systems
Improve circulation efficiency in low-energy mixing conditions
Reduce manual cleaning and maintenance frequency
Keheng side entry mixer is composed of motor, reducer, frame, mechanical seal/skeleton oil seal, propeller impeller, external support and other components. Side entry mixer can be a good solution to installation difficulties, inconvenient use, difficult maintenance and other problems, directly installed on the side of the use of the container/tank, can be a good test and maintenance, while achieving the same mixing effect.


Applications
Used in crude oil storage tanks to prevent wax deposition and solid sedimentation during long-term storage, ensuring stable oil quality and flowability.
Ensures continuous circulation in refinery storage tanks, improving process stability and reducing sludge formation at tank bottom.
Used for blending chemical liquids and solvents, preventing phase separation and maintaining consistent product quality.
Maintains suspended solids and improves flow uniformity in wastewater treatment equalization systems.
Why Choose Side Entry Mixers for Large Tanks?
Side entry mixers are preferred over top entry mixers in the following conditions:
Large diameter storage tanks
Limited vertical installation space
Continuous circulation requirements
Energy-efficient long-term operation needs
Sludge control in oil and chemical storage systems
Recommended Mixer Types by Application
| Application | Recommended Product |
| Crude oil storage | Crude Oil Tank Agitator |
| Refinery tanks | Heavy Duty Side Entry Mixer |
| Chemical storage | Belt Drive Side Entry Mixer |
| Wastewater tanks | Standard Side Entry Mixer |
Under normal circumstances, before delivery, Keheng mixer will judge according to the category of products, there are ordinary wooden boxes and fumigated wooden boxes. For the mixer that has been fully assembled, the worker will pack the impeller with bubble film, and install the motor and reducer with transparent protective film to prevent rust during transportation and corrosion by seawater molecules during shipping. Subsequently, the worker will firmly fix the mixer on the support column of the wooden box through the connecting flange, and then nail the wooden box around, and finally spray the attention mark on the surface of the box, that is, the packaging is completed and ready to be shipped.

Installation of side entry mixer: The same as the installation method of top entry mixer, before the motor and reducer enter the factory, Keheng factory will prepare the rack first, and there will be special workers to produce and polish the various types of rack, so as to reduce the waiting time of customers. After the motor and reducer come in, the prepared parts will be installed immediately. Unlike the top entry mixer, due to the influence of gravity, the impeller is generally not installed on the idling test, and the impeller is installed and packaged after the test is completed.

Cleaning:Clean the mixer thoroughly after use to remove residues and sustain efficiency.
Lubrication:Lubricate bearings and transmission parts regularly as instructed to reduce wear.
Electrical check:Inspect motors, wires and other electric parts; repair or replace damaged components promptly.
Fastener check:Tighten loose bolts and nuts to prevent operational instability.
Safety rules:Cut off power before maintenance and never service a running machine.
Routine inspection:Check all parts periodically to detect faults early.
Q1: What is a side entry mixer used for?
It is used for mixing and circulation in large storage tanks to prevent sedimentation and maintain liquid uniformity.
Q2: What industries commonly use side entry mixers?
They are widely used in oil storage, refinery, chemical processing, and wastewater treatment industries.
Q3: Can side entry mixers handle crude oil with sludge?
Yes, they are designed specifically for sludge prevention and circulation in crude oil tanks.
Q4: What is the advantage over top entry mixers?
They are more suitable for large tanks requiring continuous circulation with lower energy consumption.
