When should I choose a planetary counter-current mixer instead of a twin shaft mixer?

Choose a vertical-shaft planetary counter-current mixer when the mix is dry, fibre-reinforced, pigmented or ultra-high performance: UHPC, GFRC, refractory castables, dry-cast paving blocks and precast elements requiring homogeneity below 5% coefficient of variation. A twin shaft mixer is the more economical choice for high-throughput ready-mix and wet concrete above 2 m³ per batch, where cycle times of 30-45 seconds matter more than micro-homogeneity.

How long does a CO-NELE mixing pan liner and blade set last?

With standard high-chrome wear parts, liners and mixing arms typically run 90,000-150,000 batches on normal concrete and 40,000-60,000 batches on abrasive mixes such as refractory castables or quartz-rich UHPC. All wear parts are bolt-on and replaceable in the field, and CO-NELE keeps interchangeable spares for every model produced since 2004.

Can CO-NELE run a trial with my own raw material before I place an order?

Yes. Our laboratory in Qingdao operates lab-scale intensive mixers and granulators from 5 to 75 litres. Send 10-20 kg of your powder or aggregate with the target particle size, moisture and capacity, and our process engineers return a test report with granule sphericity, bulk density, mixing time and the recommended production model.

What voltage, documentation and after-sales support do export buyers receive?

Machines are built to the buyer's local supply (220V/380V/415V/440V, 50 or 60 Hz), supplied with CE-compliant electrical design on request, foundation and wiring drawings, an English operation and maintenance manual, and a 12-month warranty on the drive unit. Installation guidance is delivered by video commissioning or by resident engineers; spare parts ship from stock in Qingdao.

Product Description

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: Poses a health hazard to employees and results in raw material waste.

Poor Flowability: Impacts the uniformity of automated forming feeds, resulting in inconsistent product density.

Low Tap Density: Results in numerous voids between powders, impacting sintered compaction and ultimate strength.

Segregation: Mixed powders of varying particle sizes tend to separate during transport, impacting 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): A container with a disc-shaped bottom, tilted at a fixed angle (typically 40°-60°) to the horizontal. This tilted design creates complex material motion paths.

The Rotor (Agitator): Located at the bottom of the mixing disc, driven by a motor at high speed. Its plow or blade shape provides powerful shearing, stirring, and spreading.

The Scraper (Sweeper): Attached to the rotor or frame, adhering closely to the inner wall. It continuously scrapes material off walls and re-injects it into the mixing area to prevent clumping.

Drive System: Provides robust and reliable power for the rotor and mixing disc.

Liquid Addition System: Precisely and evenly applies liquid binders to the materials being mixed.

Granulator Models and Technical Specifications

We offer a variety of granulator specifications to suit diverse needs, from laboratory research and development to large-scale industrial production. Experimental-grade small granulators and large-scale granulator production lines meet functions of mixing, granulation, coating, heating, vacuuming, and cooling.

Frequently Asked Questions (FAQs)

Q1 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.

Q2 What is the approximate yield from powder to granules?

A: Our equipment is engineered to minimize material loss. Dry granulation typically achieves a yield over 98%, while wet granulation (due to drying) yields approximately 95%-97%.

Q3 Can you provide a pilot prototype for trial testing?

A: Yes. We operate a dedicated laboratory facility (1L-50L capacity). Customers are welcome to provide raw materials for free granulation trials to verify performance firsthand.

Q4 Which superabrasive materials can be processed with this granulator?

A: The granulator is optimized for superhard materials including synthetic diamond micropowder, cubic boron nitride (CBN), and associated ceramic or metallic matrix powders.

Q5 How does the granulator prevent iron contamination during processing?

A: All material contact surfaces are built using high-grade stainless steel or customized wear-resistant ceramic/polyurethane linings to completely eliminate iron ion contamination.

Q6 What capacity options are available for industrial scaling?

A: We provide scalable equipment options ranging from laboratory R&D units (0.3L–5L) up to large industrial continuous batch systems with capacities reaching 2000L.
