BARMAC Product Lines We Repair
Our engineers are trained on the full BARMAC product range. Below are the major product families we service.
B-Series VSI Crushers (B3, B4, B5, B6, B7)
Vertical shaft impact crushers for fine aggregates and recycling. Control electronics manage rotor speed, impact gap clearance, and feed rate. Common issues: rotor imbalance sensor failures, speed controller drift, hydraulic pressure transducer faults.
MVS Series Multi-Vertical Shaft Crushers
High-capacity multi-impact systems for large-scale quarry operations. Dual or triple rotor configuration with synchronized speed control and anti-blocking circuits. Repairs focus on rotor synchronisation drives and bearing temperature monitoring failures.
Grinding Mill Motors and Drive Systems
Dedicated electric motor packages and variable frequency drives for Barmac mill applications. Common faults: soft-start relay failures, thermal overload nuisance trips, phase-shift detection circuit malfunctions.
Rotor Assembly and Wear Management Electronics
Sensor arrays and timing circuits that monitor rotor wear, impact velocity, and material flow. Early failure detection prevents catastrophic impact mechanism damage. Synchronics repairs worn sensor harnesses and signal conditioning modules.
Hydraulic Pressure Control Units
Proportional solenoid-operated pressure regulators and anti-blocking accumulator management systems. Maintain tight clearance gaps between impact anvils and rotor. Faults: solenoid coil burnout, pressure sensor drift, proportional control valve stiction.
Touchscreen HMI and PLC Control Panels
Operator interface and real-time crusher diagnostics. Display feed rate, rotor RPM, current draw, and bearing temperature. Repairs include capacitive touch screen restoration, communication module failures, and firmware updates.

Common BARMAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BARMAC equipment arriving at our workshop.
- ✓Rotor Imbalance Detection Sensor Failure — Barmac VSI crushers use proximity sensors to detect rotor eccentricity. Sensor connector corrosion in dusty quarry environments, or failure of the conditioning circuit, causes false alarm shutdowns or missed critical imbalance warnings. Early detection prevents catastrophic rotor damage.
- ✓Hydraulic Proportional Solenoid Burnout — Barmac crushers modulate gap clearance via proportional solenoid valves fed by continuous 24V supply. Thermal stress, moisture ingress into coil windings, or sustained high-pressure operation causes coil insulation breakdown. Solenoid failure prevents gap adjustment and increases wear.
- ✓PLC Communication Loss with Remote HMI — Barmac PLC control panels communicate with touchscreen HMI via Ethernet or serial gateway. Cable degradation in high-vibration quarry environments, corrupted firmware, or failed communication module causes operator panel blackout and unsafe blind operation.
- ✓Rotor Speed Controller Drift and Nuisance Overspeed Faults — Barmac B-series crushers use closed-loop tachometer feedback to hold rotor RPM within tight band (typically 1500-2000 RPM). Analogue potentiometer aging, faulty tachometer pickup coil, or PID loop tuning drift causes oscillation and false overspeed warnings that trigger emergency stops.
- ✓Bearing Temperature Sensor RTD Open Circuit — Resistance Temperature Detectors (RTD Pt100) embedded in Barmac mill and crusher bearing housings fail due to vibration-induced wire fracture inside the probe, or ice formation in cable entry glands in winter months. Open RTD reads as -40°C equivalent, falsely alerting maintenance.
- ✓Motor Soft-Starter Thermal Overload Nuisance Trips — Barmac crushers coupled to 30-55 kW motors use solid-state soft-starters to reduce inrush current. High ambient quarry dust temperatures (45-50°C), blocked heat sink fins, or undersized thermal relay setting cause repeated shutdown during normal full-load impact. Reduces production uptime.

Frequently Asked Questions — BARMAC Repairs
Do you repair Barmac VSI crusher electronics anywhere in India?+
Yes. Synchronics repairs the complete Barmac product range — from B-series and MVS crushers to drive controllers, hydraulic pressure management systems, rotor imbalance detection circuits, and HMI panels. We offer PAN India doorstep pickup from all major cities: Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Visakhapatnam, and Bengaluru. All repairs are handled at our 180-engineer Vadodara facility. Standard turnaround is 5-7 working days.
What is a typical Barmac rotor imbalance sensor failure, and how long does repair take?+
Barmac crushers monitor rotor eccentricity using inductive proximity sensors wired to a PLC input module. When sensors fail — usually due to connector corrosion in dusty quarry air — the crusher triggers false high-load shutdowns and makes production unreliable. Synchronics diagnoses sensor continuity, replaces corroded M18 connectors with sealed stainless-steel versions, and recalibrates alarm thresholds to OEM tolerance. Typical repair is 2-3 days, including sensor testing and recalibration under simulated load.
How do I know if my Barmac HPU proportional solenoid is failing?+
Barmac hydraulic proportional solenoids regulate the gap between the rotor and anvil block. Failure signs: (1) gap clearance no longer adjusts smoothly from HMI; (2) crusher vibration increases; (3) bearing temperature rises; (4) system pressure alarm on display. Synchronics tests solenoid coils with megohm meter and current draw under load. If windings are open or shorted, we source OEM solenoid replacements, test them on a pressure bench rig, and return with updated sealed connectors rated for quarry dust.
Can Synchronics repair Barmac PLC and touchscreen HMI communication failures?+
Absolutely. We repair Barmac PLC-to-HMI communication breakdowns caused by corrupted Modbus RTU firmware, failed Ethernet gateway modules, or damaged serial cables. Using oscilloscope and logic analyser, we trace packet loss, reload OEM firmware from factory images, replace communication modules, and install shielded cabling with vibration-resistant M12 connectors. We validate Modbus handshake and real-time data flow before return. Typical repair: 3-4 days.
Where is your Barmac repair facility and how do I send equipment?+
Synchronics is based in Vadodara, Gujarat — India's industrial electronics hub. We have full in-house test benches for Barmac motor drives, PLC controllers, hydraulic solenoids, and sensor modules. You can call us on our hotline, and we arrange free pick-up from your quarry or plant location across India. Equipment is logged, tested, and repaired in Vadodara, with detailed repair reports and video diagnostics sent to you daily. Once complete, we courier equipment back with signature. No hidden charges.
How do I send my BARMAC unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a BARMAC drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on BARMAC repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your BARMAC unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
