What is a Dry granulating machine?

A dry granulating machine uses dry roller press technology to compress or form blocks from powder materials with a water content of ≤5%. The blocks are then crushed and screened to produce granular materials that meet usage requirements.

Dry granulating machine Working Principle

It is based on the principle of mechanical squeezing and granulation. Raw materials, which are usually crystal mixtures or powder mixtures containing some crystal water, are squeezed into a flake shape before they go through the granulation system. The sieve unit is then used to obtain final products of certain sizes.

Raw materials are put into the hopper by hand or vacuum conveyor. The horizontal screws then deliver the raw materials into the squeezing unit, which includes vertical compression rollers, to squeeze raw materials into a flake shape. The duration that the raw materials stay in the squeezing unit depends on the speed of the compression rollers. There is a hydraulic device that transfers pressure linearly to the compression rollers, and this device can maintain a certain level of pressure itself. The vertical arrangement of the compression rollers can maintain the consistency of the product’s density. Screens in the screening unit can be changed based on different requirements of the mesh size of the final product.

Feature of Dry granulating machine:

The dry powder is granulated directly without any additives. Particle strength can be adjusted, and the finished product’s strength can be controlled by adjusting the pressure of the roll. The process operates in a cycle, allowing for continuous production and high output of finished products. The material is compressed by mechanical pressure without any additives, ensuring the purity of the product.

The dry powder is granulated directly without requiring a subsequent drying process, facilitating better integration and adaptation to existing production processes. The particle strength is high, and the increase in bulk proportion is more significant than other granulation methods, making it especially suitable for increasing the bulk proportion of products.

The machine is suitable for a wide range of raw materials, and particle strength can be freely adjusted according to different materials. It features a compact structure, easy maintenance, simple operation, short process flow, low energy consumption, high efficiency, and a low failure rate.

The machine can control environmental pollution, reduce powder waste and packaging costs, and improve product transportation capacity. The feeding device uses variable frequency stepless adjustment control, providing a high degree of automation. This enables one person to operate multiple machines with low labor intensity and allows for long-term continuous operation.

The main transmission parts are made of high-quality alloy materials. The use of stainless steel, titanium, chromium, and other surface alloys greatly improves wear resistance, corrosion resistance, high-temperature resistance, and pressure resistance, contributing to the machine’s long service life.

What are the different types of granulators?

In terms of processing, pelletizer can be divided into two types: wet pelletizer, which uses liquid in the processing process, and dry pelletizer, which does not use liquid. Wet granulation involves a lot of water and detergent, and the purpose is to clean the contaminated material and also to cool the machine.

The difference between wet granulator and dry granulator:

First, Dry Granulator
Dry granulators use dry powder to produce granular material. The mixture is fed into the equipment through the hopper, where it forms particles through rotational and vibrational motion and is then sifted out through a screen with a predetermined particle size at the discharge port. Dry granulators are typically used to manufacture fertilizers, pigments, pesticides, plastic particles, and so on.
Advantages:
Dry granulators have high operating efficiency.
They have relatively low requirements for the raw materials used and do not require extensive pretreatment.
Dry granulators are relatively simple and easy to learn.
Cons:
Dry granulators can produce more dust, requiring thorough cleaning and maintenance.
Since the dry method cannot use additional lubricants during particle manufacturing, there may be deficiencies in some areas, making the wet granulator a more suitable option.
Second, Wet Granulator
Wet granulators operate with liquids or suspensions. The mixture enters the device through a hopper, forms particles inside the device, and is eventually discharged through a screen. Wet granulators are typically used to manufacture boiler fuel particles, cosmetics, and food products.
Advantages:
Wet granulators do not produce dust.
The high humidity in wet granulators helps increase the adhesion between particles, resulting in higher particle quality.
Wet granulators support the use of additional lubricants, which can make particles more suitable for certain applications.
Cons:
Wet granulators are more complex and relatively difficult to operate.
In some cases, the pretreatment process required to produce wet particles may be more complex.
The production efficiency of wet granulators is not as high as that of dry granulators, taking longer manufacturing time.
In summary, although dry granulators and wet granulators are both pellet manufacturing equipment, their working principles, application fields, and advantages and disadvantages differ. Enterprises should choose the appropriate method based on their needs and the comparison of advantages and disadvantages described in this article.”

Dry Granulating Machine uses in pharmaceutical industry:

The pharmaceutical industry is closely related to human health and life safety, and every aspect of its production process requires strict control. In pharmaceutical manufacturing, granulation is a crucial step that directly affects the quality, stability, and efficacy of drugs. As an advanced granulation method, dry granulation plays an important role in the pharmaceutical industry. This article will explain the importance of dry granulation in the pharmaceutical industry from the following perspectives.
First, dry granulation can improve the stability of drugs. In the pharmaceutical process, the size, shape, and surface condition of the particles significantly influence drug stability. Dry granulation ensures that the drug and auxiliary materials are evenly mixed through the high-speed rotating granulator, resulting in drug particles with a more regular shape and smoother surface, thereby enhancing the stability of the drug. Additionally, the dry granulator can adjust pressure, temperature, and other parameters during the granulation process according to the characteristics of the drug, enabling the drug to maintain good stability under different conditions.
Secondly, dry granulation can enhance the dissolution rate of drugs. The dissolution rate of a drug in the body directly impacts its efficacy. By precisely controlling pressure, temperature, and other parameters during the granulation process, the dry granulator ensures that the drug particles have higher porosity and better fluidity, which improves the dissolution rate of the drug in the body. This is especially important for medicines requiring rapid action, such as emergency drugs and antibiotics.
Thirdly, dry granulation can improve the bio-availability of drugs. Bio-availability refers to the extent to which a drug is absorbed in the body and becomes active. By optimizing the granulation process, drug particles achieve good fluidity and high dissolution rates, thereby increasing the bio-availability of drugs in the body. This is particularly significant for oral drugs, as their bio-availability directly affects drug efficacy.
In addition, dry granulation offers the advantages of simple operation, high production efficiency, and low energy consumption. Unlike traditional wet granulation, dry granulation does not require the addition of solvents, which reduces environmental pollution and production costs. Furthermore, the high level of automation in dry granulation allows for continuous production, significantly increasing production efficiency
