Tecniwell TWM 30 Maintenance Checklist

Daily inspection and cleaning, weekly preventive maintenance, shutdown storage and diagnostic actions for the TWM 30.

Configuration note: Maintenance information below is based on the referenced TWM 30 machine documentation. Confirm the machine serial plate, installed configuration and applicable manual revision before applying maintenance procedures or component specifications.

Daily Inspection & Cleaning

Complete once per operating day and follow the stated machine-state requirement for each task.

Every operating day
1

Pneumatic valve circuit

Plant ON: read the valve-circuit gauge. Correct range: 5–6 bar.

Act if: pressure is outside range, unstable or falls abnormally.

2

Silo blower gauge

Plant ON: read the silo-blower air gauge. Correct range: 7–8 bar.

Act if: pressure is outside range or the blower circuit leaks.

3

Pneumatic lubricator oil

Plant OFF: confirm the reservoir level is between MIN and MAX.

Act if: level is low/high, oil is contaminated or the reservoir leaks.

4

Mixer & agitator first wash

Plant ON, manual mode: admit water and run one complete mixing cycle through the agitator piping, booster pump and discharge.

Act if: flow is obstructed, leakage occurs or clear discharge cannot be established.

5

Mixer & agitator final wash

Plant OFF and isolated: remove residual grout from both tanks and clean the screening basket.

Act if: hardened deposits remain or safe isolation cannot be confirmed.

6

Pipelines

Flush for at least 10 minutes, or until clear water exits the grout delivery pipe to the downstream pumping unit.

Act if: clear discharge is not achieved or a line remains obstructed.

7

Water filter

Plant OFF: clean the water filter as part of the daily cleaning intervention.

Act if: the filter is damaged, blocked or cannot be restored cleanly.

8

Screening basket

Remove the basket from its seat and clean it thoroughly.

Act if: it is damaged, distorted, blocked or cannot be correctly reseated.

9

Machine compartment

Wash with service water. Do not use solvents or aggressive products.

Act if: water could contact unsafe live equipment or cement contamination remains.

10

Guards & covers

Restore all guards, tank-cover locks and safety devices before returning the plant to service.

Act if: any guard, cover lock, interlock or emergency stop is missing, damaged or bypassed.

11

Maintenance record

Record gauge readings, cleaning completion, defects, actions taken and the current hour-counter reading.

Act if: a safety-critical defect remains open or the plant configuration is uncertain.

Preventive Maintenance Schedule

The plant schedule uses weekly, condition-based and component-supplier frequencies rather than fixed plant operating-hour intervals.

Unless a task explicitly requires an ON visual check, isolate the plant and control stored energy before maintenance.
Drive & bearings

Belt-drive bearings

OFF: Lubricate the bearings. Confirm the correct bearing-grease grade from machine-specific documentation before filling.

LUBRICATE

Mixer drive belt

OFF: Remove the protective housing, inspect tension and wear, adjust if necessary and replace the belt if worn.

INSPECT
Pump & valves

Booster-pump seal

ON visual check: Inspect the seal for leakage. Use the fitted pump documentation for further service.

CHECK

Recirculation & transfer valve sleeves

ON inspection / OFF replacement: Clean valve bodies and check for leakage. Empty and isolate the mixer, piping and pneumatic supply before sleeve replacement.

INSPECT
Agitator

Lower-paddle scraper

OFF: Inspect the rubber scraper blade for wear. Tank intervention requires one technician working and a second technician as safety watch.

INSPECT
Operator compartment

Controls & compartment

Safe state: Clean the control board, electrical cabinet exterior, data printer, viewing glass and ceiling lamp.

CLEAN
Mixer-impeller wear depends on grout type, so no fixed inspection frequency is specified.
Mixer impeller

Noise & vibration observation

ON observation: Monitor the mixer for abnormal vibration or noise during operation.

MONITOR

Impeller inspection

OFF inspection: If abnormal, isolate and empty the mixer, remove the lower access screw/plug, inspect the impeller and replace it if worn.

INSPECT
Air-compressor hour intervals, oil, filter and belt tasks are controlled by the manual for the compressor actually fitted to the plant.
Air compressor

Identify fitted compressor

Record compressor make, model and serial number before applying any operating-hour service interval or consumable specification.

VERIFY

Component service

Apply oil, filter, belt/coupling, condensate and other service tasks only from the confirmed compressor documentation.

FOLLOW MANUAL

Shutdown, Storage & Return to Service

Storage actions differ for inactivity of one week or less and for periods longer than one week.

Plan before shutdown
Short term — one week or less

Storage location

Store the plant in a sheltered, dry location.

STORE DRY

Water & grout system

Leave the water tank completely empty. Drain and clean the mixer, agitator tanks and piping.

DRAIN & CLEAN

Compressor

Drain compressor condensate according to the fitted compressor documentation.

DRAIN

Additional preservation

No additional maintenance intervention is specified for short-term inactivity.

RECORD
Long term — more than one week

Storage & corrosion control

Store sheltered and dry. In high humidity, apply a thin film of lubricating oil to exposed mechanical parts and protect vulnerable unpainted parts.

PRESERVE

Water & grout system

Empty the water tank and drain and clean the mixer, agitator tanks and all associated piping.

DRAIN & CLEAN

Load cells

Grease using the serial-specific approved product; do not select a grease grade by assumption.

GREASE

Mixer belt drive

Grease the mixer belt-drive mechanism with the confirmed approved bearing grease.

GREASE

Compressor

Drain condensate and complete the storage actions specified for the fitted compressor.

PRESERVE

Electrical supply

Disconnect power cables and protect terminations from contamination and moisture.

ISOLATE
Return to service

Release inspection before restart

Remove preservation materials, inspect for corrosion or moisture, reconnect through authorised personnel, restore guards, confirm free drainage, verify safety devices and complete the daily checklist before production.

INSPECT

Alarm & Diagnostic Actions

Use the indicated action as the first response. Stop and isolate the plant before any intrusive inspection.

Red — rectify before continuing Amber — inspect condition
RED

Electrical power OFF

A power interruption has compromised operating conditions.

Action: Identify and remove the cause, then resume the mixing cycle only through the normal restart procedure.

If ignored: unexpected or incomplete cycle state.

RED

Incorrect phase sequence

Electrical phases are reversed and motors rotate in the wrong direction.

Action: Qualified electrical personnel must correct the phase sequence at the external connector or main electrical panel.

If ignored: reverse rotation and equipment damage.

RED

AIR LOW

Pneumatic-valve circuit pressure is at or below 4 bar.

Action: Confirm compressor operation and inspect the pneumatic circuit piping for leakage.

If ignored: valves may not operate reliably.

RED

Electrical protection ON

A motor fault has tripped a protective breaker.

Action: Identify the affected motor, check electrical input and mechanical load, remove the fault or replace the motor, then reset the breaker.

If ignored: motor, cable or driven-equipment damage.

AMBER

Mixer abnormal noise or vibration

Foreign material may be in the mixer, or the impeller may be worn or damaged.

Action: Stop and isolate. Check for foreign bodies and inspect the impeller; replace if necessary.

If ignored: progressive impeller or mixer damage.

AMBER

Agitator abnormal noise or vibration

Foreign material, insufficient grout level or a worn lower-paddle rubber scraper may be present.

Action: Stop and isolate. Remove foreign bodies, confirm product level and inspect the scraper blade; replace if worn.

If ignored: paddle, scraper or tank damage.

AMBER

Compressor abnormal noise or vibration

Detailed diagnosis depends on the compressor fitted to the plant.

Action: Stop the compressor if unsafe and follow the confirmed compressor documentation.

If ignored: compressor or receiver-system failure.
