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.

CHS 1000 concrete mixer — 1000 liters twin shaft concrete mixer

CO-NELE Twin-Shaft Mixer Advantages

1 The shaft end seal is equipped with a floating oil seal ring, a special labyrinth seal structure composed of a seal and a mechanical seal, which has reliable sealing, high stability and long service life;

2 Automatic lubrication system configuration, four independent oil pump, high working pressure, excellent performance;

3 On-mounted motor installation layout, patented belt self-tensioning device to improve transmission efficiency, to avoid excessive wear and damage to the belt, reduce maintenance costs,The large volume ratio design concept is adopted for the helium cylinder, which can effectively improve the mixing efficiency, prolong the service life of the shaft end seal, and reduce the probability of material shaft holding;

4 Discharging door adopts eccentric double sealing design to prevent material jamming and leakage, small wear, high sealing efficiency and long-lasting;

5 Stirring device adopts a patented design with an angle of 60°. Flow line casting of the stirring arm results in uniform mixing, low resistance, and low rate of material holding shaft;

6 Configured with military-grade planetary speed reducers with smooth transmission and high load capacity;

7 Optional original Italian reducer, original German automatic lubrication pump, high pressure cleaning device, temperature and humidity testing system;

Frequently Asked Questions (FAQ)

Q: What is the output capacity of the CHS1000 double shaft concrete mixer?

The CHS1000 model features an incoming capacity of 1500L and a discharging output capacity of 1000L per batch, making it ideal for standard commercial concrete production.

Q: How does the shaft end sealing system ensure durability?

It utilizes a floating oil seal ring combined with a specialized multi-labyrinth seal structure and mechanical seal, effectively preventing slurry leakage and significantly extending service life.

Q: What are the electrical power specifications for the CHS1000 model?
