Powder Granulator

A powder granulator is a machine or system used to transform fine powders into larger, denser, free-flowing granules. This process (granulation) improves powder handling, reduces dust, enhances dissolution, and ensures uniformity in industries like pharmaceuticals, food, chemicals, and agriculture.

Why Granulate Powders?

Improved Flow: Enables uniform filling in packaging/tableting.
Dust Reduction: Safer handling, less product loss.
Controlled Dissolution: Adjustable granule density/size for solubility.
Mixing Uniformity: Prevents ingredient segregation.
Compaction: Essential for tablet manufacturing.

CO-NELE mixing granulator, with its original turbulent three-dimensional mixing granulation technology, has achieved a 3-fold leap in efficiency! Compared with traditional equipment, CO-NELEz granulator can compress the original hours of mixing granulation process to just tens of minutes when processing refractory materials, glass raw materials, ceramic raw materials, catalysts, molecular sieves, powder metallurgy and other materials.

The independent control cabinet is equipped with a PLC touch screen control system, which is easy and accurate to operate. Whether it is large-scale production or small batch customization, it can be easily handled. The specially designed granulation tool set is not only wear-resistant and durable, but also can effectively improve the uniformity of material mixing, and escort product quality.

Key Types of powder Granulators:

Significant reduction of dust:

Advantages: This is one of the core advantages. When handling fine powders, flying dust is a serious problem, causing environmental pollution, waste of raw materials, equipment wear, cleaning difficulties, and most importantly, endangering the health of operators (respiratory diseases, explosion risks).

Granulation effect: Agglomerating fine powders into granules greatly reduces the generation and spread of dust, improves the working environment, and complies with safety and environmental regulations.

Improving fluidity and handling:

Advantages: Fine powders have poor fluidity and are prone to agglomeration and bridging, resulting in poor flow in silos, pipelines, and feeders, affecting production efficiency and metering accuracy.

Granulation effect: Granules have better flow characteristics and can flow smoothly like “sand”, which is convenient for conveying, packaging, metering, filling molds (such as tablet presses) and automated operations, improving production speed and stability.

Improve volume density/bulk density:

Advantages: Powders are usually fluffy, taking up a lot of storage and transportation space, increasing costs. Low density may also affect downstream processes (such as tablet strength, dissolution rate).

Granulation effect: The granulation process removes the air between powder particles through compression and agglomeration, significantly improving the bulk density of the material. This means:

Save storage space: Smaller volume at the same weight.

Reduce transportation costs: More materials can be transported at a time.

Optimize packaging: Use smaller packaging containers.

Improve downstream processes: Such as higher tablet hardness or more controllable dissolution behavior.

Improve solubility or dispersibility:

Advantages: Some applications (such as instant beverages, granules, pesticide wettable powders, dyes) require materials to dissolve quickly or disperse evenly in water.

Granulation effect: By controlling the granulation process (such as wet granulation), porous and easily disintegrated particles can be produced, which have a larger specific surface area (relatively) than fine powder, thereby accelerating the dissolution or dispersion speed and improving product performance.

Improve material mixing uniformity:

Advantages: In a powder mixture, differences in density and particle size of different ingredients may lead to stratification (segregation) during transportation or storage, affecting the quality consistency of the final product.

Granulation effect: Granulate the mixed powder into granules, “lock” multiple ingredients inside each granule, effectively prevent segregation, and ensure the high uniformity of the ingredients of the final product.

Reduce waste and loss:

Advantages: Dust flying and adhesion will lead to raw material loss; poor fluidity will lead to more equipment residue and inaccurate metering.

Granulation effect: Reduce dust loss, improve fluidity, reduce equipment residue, and improve metering accuracy, all of which directly reduce raw material waste and production costs.

Optimize product appearance and commercial value:

Advantages: Granular products usually look more regular, more professional, and more “advanced” than powders, and are more acceptable to consumers.

Granulation effect: It can produce particles with uniform size and regular shape (such as spherical and cylindrical), which can improve the appearance quality and market competitiveness of products (such as laundry detergent particles and instant coffee particles).

Easy to control release:

Advantages: In the fields of pharmaceuticals, fertilizers, pesticides, etc., active ingredients are sometimes required to be released slowly or at a specific rate.

Granulation effect: The granulation process (especially wet or melt granulation) provides a good basis for subsequent coating or controlled release by controlling particle density/porosity.

Improve reaction efficiency (specific fields):

Advantages: In the fields of metallurgy (sintered ore), catalysts, etc., the size and pore structure of particles are more conducive to gas diffusion and chemical reaction than powders, which improves the reaction rate and efficiency.

Improve recovery rate (such as metal powder):

Advantages: In metal powder metallurgy or 3D printing, unused fine powder needs to be recycled. It is difficult to recycle in powder state and the loss is large.

Granulation effect: After the fine powder is granulated, it is more convenient to recycle and the loss is lower
