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.

CDW100 Laboratory dry mortar mixer Working Principle

Use mechanical force to evenly mix two or more powders. Through the two reverse-running stirring devices designed for the single-shaft forced mixer in the mixer, the materials are sheared, rubbed, and squeezed to achieve uniform mixing.

CDW100 Laboratory dry mortar mixer Structural Features

Drive mode:

Adopt planetary reducer drive method, with large torque, high safety factor, stable operation, and can effectively improve stability and service life.

Stirring arm and main shaft:

The stirring arm adopts a removable structure for easy installation and maintenance; the stirring main shaft adopts a hollow shaft structure with higher torsional strength.

Stirring knife:

It adopts a blade structure, with efficient stirring effect and strong homogeneity.

Transmission belt:

The device can automatically adjust the tightness of the belt, improve transmission efficiency, and reduce the labor of workers.

Sampler:

The sampler using a pneumatic device can perform real-time sampling and inspection of the stirring material, so as to determine the mixing time and ensure the mixing quality.

Discharge door:

The discharge door adopts a structure of multiple small openings, which allows for rapid discharge and less residual material. Each opening corresponds to a disassembled and replaced discharge door, which is convenient for maintenance. The transmission structure of the discharge door has a self-locking function, which can prevent the discharge door from opening when the air supply is suddenly interrupted, affecting the mixing of materials.

CDW100 Laboratory dry mortar mixer Performance advantages

Good mixing effect: Equipped with a high-speed rotating flying knife, it can effectively disperse the agglomerated fibers, so that the materials can be continuously circulated and sheared in an all-round manner, so as to achieve the purpose of rapid and gentle mixing.

Wide range of applications: It can be used for mixing a variety of dry powders and fine granular materials, such as putty powder, plaster, colored cement, various mineral powders, etc., and is suitable for building materials, special mortars, flooring, wall coatings and other industries.

Easy operation: The structural design is reasonable, the operation is intuitive, and the equipment is sturdy and durable, with a low failure rate, which is convenient for daily use and maintenance.

CDW100 Laboratory dry mortar mixer Application areas

Mainly used in scientific research and small-scale production fields, such as small sample tests when building materials companies develop new products, and sample preparation before mortar performance testing in construction laboratories, etc.
