CONELE Underground Mixer

CONELE Underground Mixer

The CONELE Underground Mixer is an on-site mixing unit developed for underground working faces, moving the mixing step to the extraction and backfill site for "mix-as-you-mine, feed-from-nearby." It compresses the long chain of surface centralized mixing into a single underground point, so materials are blended evenly right where they are needed.

Underground Value

 

Underground, shuttling materials between surface and shaft means transport risk and process loss. The underground mixer reduces transfer trips and shortens the feeding path through on-site mixing, lowering personnel exposure and occupation, safeguarding backfill and production continuity, and aligning with the mine's goal of "fewer people, higher efficiency, safety by reduction."

 

Underground Mixe Core Features

 

On-site Mixing

Blends materials near the working face, cutting the risk of surface-shaft shuttling and handling.

01

Man-Machine Safety

Flameproof electrics and remote operation reduce personnel contact and exposure underground.

02

Harsh-environment Tolerant

Resists high humidity and dust, fits confined spaces, and runs stably in complex underground conditions.

03

Easy Maintenance

Modular components allow quick underground repair and replacement, shortening unplanned downtime.

04

Application Conditions

Suitable for extraction faces, heading faces, underground backfill faces, and various temporary mixing points-covering coal, metal, and other mines requiring compliant underground work, and meeting continuous-operation needs in confined, harsh environments.

Safety & Compliance

The unit adopts a mining flameproof electrical scheme, is certified with the CMAC mining-product safety mark, and uses MA-system certified core parts-meeting mining safety standards from design to components, and safeguarding underground-operation qualification and personnel safety.

 

FAQ

 

Q:What is an underground mixer? What working scenarios is it suitable for?

A:Underground mixer is heavy‑duty forced‑action mixing equipment modified for confined underground mine & tunnel environments. CO‑NELE twin‑shaft / planetary underground mixers are widely used for shotcrete, mine backfill concrete, tunnel segment pre‑mixing, underground roadway support concrete mixing. It adapts to narrow space, high‑dust, high‑humidity underground working conditions.

Q: How long for stationary concrete batching plant installation and commissioning?

A:After foundation curing, mechanical installation takes 4‑8 weeks; commissioning & calibration takes extra several working days.

Q: What mixer types does CO‑NELE supply for underground projects?

A:We provide twin‑shaft intensive mixers and planetary mixers for underground applications. Twin‑shaft models suit large‑volume backfill concrete; planetary mixers deliver high‑uniformity mixing for shotcrete, steel‑fiber reinforced concrete for underground supportCO-NELE

Q:Can CO‑NELE underground mixer handle steel‑fiber reinforced concrete for tunnel support?

A:Yes. CO‑NELE heavy‑duty mixing rotor design realizes uniform fiber dispersion without fiber balling. Optional automatic fiber feeding device is available for underground working conditionsCO-NELE
