Diamond Powder Granulator: Core Equipment for Improving Superabrasive Quality and Efficiency

CONELE develops high-performance diamond powder granulators specifically for the superabrasive industries, including diamond and cubic boron nitride (CBN). Through our advanced dry-process three-dimensional mixing and granulation technology, we help customers transform fine powders into dense granules with high sphericity, excellent fluidity, and uniform particle size. This significantly improves subsequent molding and sintering processes, maximizing product value.

Why is diamond powder granulated?

Diamond micropowder, when used directly in the production of grinding wheels, discs, cutting tools, and other products, presents numerous challenges:

Dust generation: This poses a health hazard to employees and results in raw material waste.

Poor flowability: This impacts the uniformity of automated forming feeds, resulting in inconsistent product density.

Low tap density: This results in numerous voids between the powders, impacting sintered compaction and ultimate strength.

Segregation: Mixed powders of varying particle sizes tend to separate during transportation, impacting product consistency.

CONELE’s granulation equipment perfectly addresses these challenges and is a key step toward achieving automated, high-quality production.

Core Principle of the Inclined Intensive Mixing Granulator

The operating principle of the inclined intense mixing granulator is based on the synergistic effect of an inclined mixing disc (barrel) and a specially designed rotor (agitator). It achieves uniform mixing of materials (including powders and liquid binders) in a short period of time through a combination of convective mixing, shear mixing, and diffusion mixing. Mechanical forces aggregate the materials into the desired granules.

Main Components of a Granulator

The inclined mixing disc (barrel): This is a container with a disc-shaped bottom, tilted at a fixed angle (typically 40°-60°) to the horizontal. This tilted design is key to creating complex material motion paths.

The rotor (agitator): Located at the bottom of the mixing disc, it is typically driven by a motor to rotate at high speed. Its specially designed shape (such as a plow or blade) is responsible for providing powerful shearing, stirring, and spreading of the material.

The scraper (sweeper): Attached to the rotor or separately, it adheres closely to the inner wall of the mixing disc. It continuously scrapes away material adhering to the disc walls and re-injects it into the main mixing area, preventing material from clumping and ensuring seamless mixing.

Drive System: Provides power for the rotor and mixing disc (on some models).

Liquid Addition System: Used to precisely and evenly apply liquid binder to the materials being mixed.

Frequently Asked Questions (FAQs) about Diamond Powder Granulators

Q What is the granular strength of diamond powder after granulation? Does it affect sintering?

A: We can precisely control granular strength by adjusting the binder type and dosage. The granule strength is sufficient for normal transportation and will decompose smoothly during the initial sintering process, without any negative impact on the final product.

Q What is the approximate yield from powder to granules?

A: Our equipment is designed to minimize material loss. Dry granulation typically achieves a yield of over 98%, while wet granulation, due to the drying process, has a yield of approximately 95%-97%.

Q Can you provide a pilot prototype for testing?

A: Yes. We have a professional laboratory (1L-50L capacity). Customers can provide raw materials for free granulation trials to verify the results firsthand.
