Mining and cement plant monitoring in Tanzania — hear the bearing fail before it stops the plant.
Vibration, temperature and current monitoring on crushers, mills, kilns, fans and conveyors — from processing plants in the Lake Zone gold belt around Mwanza and Geita to cement plants on the coastal corridor and in the southern highlands. When a critical machine stops, the whole plant stops; addanode gives your maintenance team the trend line that says "this bearing has three weeks left" instead of a 02:00 phone call.
Unplanned downtime is the most expensive machine on site.
Crushers and mills that stop everything
A seized crusher bearing or a mill gearbox failure doesn't take out one machine — it takes out the day's production, and the replacement part may be weeks away through the port of Dar es Salaam. Vibration and temperature trends turn that surprise into a planned maintenance window with the part already ordered.
Kilns, fans and the cost of a cold restart
In a cement plant, an unplanned kiln stop costs fuel, refractory life and days of lost clinker. Monitoring kiln drive current, main fan vibration and bearing temperatures catches the drift early — and energy-per-tonne trends show when something is quietly getting worse.
Sites too remote for daily inspection
Contractors and exploration camps in the Lake Zone can't put a condition-monitoring technician on every site. Battery- and solar-powered sensors with store-and-forward telemetry watch pumps, gensets and crushers continuously — and report to Mwanza, Dar es Salaam or Johannesburg over whatever link the site has.
Engineered for Tanzanian mine and plant conditions.
- Remote sites on their own power. Many Lake Zone sites run on solar and generators, far off the grid. Our sensors run for years on batteries, gateways run from solar with battery buffer, and everything stores and forwards — a generator changeover or a dead link never leaves a hole in the vibration history.
- Load management on grid-fed plants. Where plants take grid power, hydro-dry years bring rationing and switching. Monitoring rides through on battery buffer, and the same data cleanly separates power-supply problems from machine problems — an argument-settling distinction on any plant.
- Dust, heat and vibration as the baseline. Crusher stations and clinker lines are hostile places for electronics. We specify sealed, industrial-grade sensors and mount telemetry away from the abuse, with remote diagnostics so a flaky node is spotted from Johannesburg, not on a site walk.
- Specialists a flight away. Vibration analysts are scarce in Tanzania. The platform does the first tier automatically — baselines, trend alarms, threshold alerts to WhatsApp — so your fitters act on clear signals, and specialist review happens remotely on the recorded data.
- Environmental obligations. Dust, noise and water are monitored realities on Tanzanian mining and cement licences. The same telemetry backbone carries dust deposition, weather, and discharge or abstraction flows — one system, one dashboard, an audit-ready record.
Based on deployments across Southern Africa, each configuration is adapted for Tanzanian site conditions. We work with mine owners, contractors and processing plants — and we don't name clients we don't have.
What gets monitored, machine by machine.
Crushers & mills
Vibration and temperature on bearings and gearboxes, motor current signature, throughput correlation — the classic early warnings, trended per machine.
Kilns & fans
Drive current, main and ID fan vibration, bearing temperatures, energy per tonne — catching imbalance and bearing wear before a forced stop.
Conveyors & pumps
Pulley and drive-end bearing health, belt-drift and run signals, dewatering and slurry pump duty — dry-run and blockage alerts included.
Site & environment
Genset and fuel monitoring, dust and weather stations, water abstraction and discharge — the licence-and-logistics layer on the same platform.
Wireless vibration sensors bolt onto bearing housings without machining; gateways read existing PLCs and protection relays over Modbus, OPC-UA and 500+ other protocols. A first machine group is typically live within weeks — installed by your own fitters and electricians under our remote guidance.
Asset, failure and the warning a sensor gives
| Asset | Typical failure | Sensor | Warning window |
|---|---|---|---|
| Kiln drive and support rollers | Bearing damage, misalignment | Vibration, temperature, motor current | Weeks to months |
| Ball and vertical mills | Bearing and gear damage | Vibration, current signature | Weeks |
| Crushers | Main-shaft bearing, eccentric wear | Vibration, temperature | Weeks |
| ID fans and baghouse fans | Imbalance, bearing failure | Vibration, current | Weeks |
| Conveyors | Drive bearing seizure, belt drift | Vibration, idler temperature, drift switches | Days to weeks |
| Slurry and dewatering pumps (mines) | Cavitation, seal wear | Vibration, current, pressure | Days to weeks |

Mining and cement monitoring in Tanzania — common questions
What is condition monitoring on a crusher or mill?
Continuous measurement of vibration, bearing temperature and motor current on the machine's critical points. Healthy machines have a stable signature; developing faults — bearing wear, imbalance, misalignment, gear damage — change it weeks before failure. The platform baselines each machine and alerts when the trend leaves the healthy band.
Does vibration monitoring really catch failures early?
For rolling-element bearings, imbalance and misalignment — the failure modes that dominate crushers, fans and conveyors — vibration trending is the established early-warning method used across heavy industry worldwide. It converts the most common catastrophic stops into planned repairs.
Can you monitor a remote mine site with no grid power and no coverage?
Yes — that is a design case, not an exception. Sensors run on multi-year batteries, the gateway runs on solar with battery buffer, and data moves by private LoRaWAN on site plus whatever backhaul exists — 4G at the camp, or a satellite link you already have. Everything stores and forwards, so intermittent links deliver complete history.
Can addaNet integrate with our existing plant PLC or SCADA?
Yes. addaNet reads existing PLCs, protection relays and meters across 500+ industrial protocols including Modbus RTU/TCP and OPC-UA. Your control system keeps controlling; addaNet adds the monitoring, trending and alerting layer on top — plus wireless sensors on machines the PLC never saw.
Do you also monitor dust and environmental parameters?
Yes. Dust deposition, weather, noise, and water abstraction and discharge flows can ride on the same telemetry backbone as machine health — one dashboard and a continuous, timestamped record that is far easier to defend than monthly manual readings.
Do you work with mining contractors as well as mine owners?
Yes. Contractors are often the fastest adopters in Tanzania — their crushers, pumps and gensets earn by the operating hour, on someone else's site, far from their own workshop. A contractor in Mwanza can watch every deployed machine across the Lake Zone on one screen.
How do we start, and what does it cost?
Start with the machines whose failure hurts most — typically one crusher station or one kiln group. After a free remote assessment (equipment list, photos, a video walk-through), you get a written proposal with cost bands. No site visit is needed to quote, which matters when the site is 1,000 km from anywhere.
Wider context: Tanzania is installing continuous pollution monitoring on the regulator’s side — see mining water compliance in Africa for what that means alongside Zambia’s SI 3 of 2026, South Africa’s GN 704 and GISTM.
