Rotary Drum Mixer

The Hywell gentle touch mixing technology (gentle mixing machine) is developed for mixing and processing fine powders, granulates, and natural products. the rotary drum mixer use to mix to a high degree of homogeneity in a short time is one of the main advantages of this technology. Even very sensitive, fragile materials can be mixed and processed without degradation, heating up due to friction, or even topical hot spots due to high-speed tooltips (e.g. paddles, ribbons). so the rotary drum mixer is also named a gentle mixing machine or gentle powder mixer.
The key to our rotary drum mixing machine is that rather than paddles or ribbons impacting the product with speed and force displace particles and have these particles hit and move the surrounding product. our technology carries the product to a position for gravity to let it flow and redistribute itself. The beauty of gravity is, that it is the same everywhere. So rather than localized chain reactions of impact, speed, and force we have equal gravity everywhere causing an efficient and gentle mixing flow.
Industrial rotary drum powder mixer are widely used as mixing machines for solid medicine powder in pharmaceuticals, Foods, and Chemicals powders.

Rotary Drum Mixer Introduction

The Hywell Machinery YYH one dimensional mixer is new kind of equipment with high efficiency and simple structure which was improved by our company. the Rotary Drum Mixer is easy to clean up. When operation, the barrel loaded materials will be rotation, motion around central shaft nevertheless material inside the barrel will make three dimensional motion. Therefor the mixing accuracy of material can be compared with two dimensional mixer and three dimensional mixer. the rotary drum mixer is also called one dimensional mixer, rotating horizontal mixer, rotary drum blender.

this rotatory drum mixer is a compact system and it only requires a small space. rotating horizontal blender is easy and simple to operate, and it is quiet and safe. The mixing chamber design is simple, so it's easy to clean. This machine is a most useful mixer for GMP foods and pharmaceutical industries’ use. The rotary drum mixer is also named a gentle mixing machine or gentle powder mixer.

Rotary Drum Mixer Working Principles

The rotary drum powder mixer is mainly composed of a barrel, a transmission system (motor, reducer coupling, etc.), and a base (including a controller). The cylinder containing the mixed material rotates at a uniform speed under the drive of the motor. Because the inner wall of the cylinder is welded with a number of special "plates", the material moves in the circular direction along the cylinder wall under the push of the copy board, that is, With the up, down, left, and right direction of movement, and because the board is at a certain angle with the central axis of the cylinder, the material moves forward and backward in the cylinder to achieve the purpose of mixing. the powder mixer is suitable for mixing all powder and granule materials.

Gentle Rotary Drum Powder Mixer Application:

Industrial food mixers

The industrial rotary drum blender has proven to be a highly valuable solution in food manufacturing processes. the food powder industrial mixers exercise virtually no shear forces making them particularly suitable for use with fragile and heat-sensitive products. Examples of powders mixed by powder mixers are milk powders, coffee, and vitamin powders.

Industrial chemical mixers

enable a large variety of materials to be treated with a range of processes in one machine.

A wide variety of chemical products and polymers are processed in industrial chemical blenders. Some typical applications are for instance: polymers, compounds, ceramics for electronics Super Adsorbent Powder used in sanitary products, etc. Moreover, Hywell rotary drum powder mixers are suitable for powders. Examples of powders mixed by the powder mixers are detergents, battery powders, and metal powders.

Pharmaceutical blenders

pharmaceutical mixers have proven to be a highly valuable part of the processing of a number of pharmaceutical products.

The fact that the Hywell industrial mixers exercise virtually no shear forces makes them particularly suitable for use with fragile and heat-sensitive products. A typical example of pharma products is the post-blending of agglomerated products with additives.


Rotary Drum Mixer Advantages

The rotary drum powder mixer is ideally suited to delicate and abrasive materials, because, the combination of low speed and no moving parts within the mixer produces a no-shear, gentle mixing action. Hywell machinery tumbler mixers had the following advantages over conventional solutions.

1.    Short mixing times of the rotary drum powder mixer: due to lack of friction, no temperature rises or even topical hot spots

2.    Gentle Mixing of the rotary drum powder mixer: The contraflow blades lift and quickly transfer the fluidized product around the mixer, under these conditions powders and granules of widely different bulk densities and particle sizes can move freely ensuring a rapid and gentle mix.

3.    Low power of the rotary drum powder mixer: Low rotational drum speed and the minimum number of mixing blades combined with no moving parts in the mixer product provide ideal conditions to gently mix flakes or highly abrasive products with minimum wear. This also provides for low maintenance and operating costs.

4.  Low maintenance costs of the rotary drum powder mixer: The efficient mixing blade design combined with no drive parts or bearings being exposed to the product results in minimum power requirements and maintenance-free operation for long periods of continuous running.

5.    Quick and easy to clean to provide good hygienic security

6. The rotary drum mixer's novel design, compact structure, good appearance, and evenness of mixing reach 99%.

7. Highly polished inner and outer surfaces of the barrel, no dead comer, easy to discharge materials, easy to clear, no cross-contamination. Confining the requirement of GMP.

8. Low-cost and highly-efficient way of mixing powdered and granular materials

Safety Precautions


Safety should be a top priority when operating a rotary drum mixer. Here are some key safety precautions to follow:

Training

Ensure that operators receive proper training on the safe operation of the mixer. They should be familiar with all controls, emergency shutdown procedures, and safety protocols.

Personal Protective Equipment (PPE)

Provide operators with appropriate PPE, such as safety goggles, gloves, and protective clothing, to protect against potential hazards.


Guarding

Install guards or barriers around the mixer to prevent accidental contact with moving parts during operation.

Emergency Stop

Ensure that an easily accessible emergency stop button or switch is available to immediately halt the mixer's operation in case of any safety concerns or emergencies.


Common Issues and Troubleshooting


Despite their robust design, rotary drum mixers may encounter some common issues. Here are a few troubleshooting tips:

Uneven Mixing

If the materials are not mixing evenly, check if the blades or paddles are properly aligned and in good condition. Adjust or replace them if necessary.

Motor Overload

If the mixer's motor is frequently tripping or overheating, it may be due to excessive material load or an issue with the motor itself. Reduce the batch size or consult a technician to inspect the motor.

Leakage

If there is leakage around the drum or shaft seals, inspect and replace any worn or damaged seals to prevent product loss and ensure airtight operation.
