Engineering verification of wear plates, take-up screw units, and idler rolls by serial

WÖHWA Typ 01.1 RD and 01.1 HD flat sliding gates

Electromechanical flat sliding gates from WÖHWA type 01.1 regulate and cut off dry bulk materials discharging from silo openings. Rigid gate blade construction prevents binding when gravel particles enter the throat, guaranteeing dependable flow control onto downstream belts.

Regular Duty 01.1 model with 3 kW electric drive achieving throughputs up to 1000 t/h
Heavy Duty 01.1 unit utilizing 2.2 kW drive geared for abrasive streams up to 800 t/h
Galvanized frame steelwork protecting guide bearings against dust and weather exposure
Selection of electric actuators, slide blades, track rollers, and limit sensors by code

WÖHWA Typ 08.1 double-flange sealed sliding gates

Dust-tight double-flange sliding gates from WÖHWA type 08.1 isolate fine powders, mineral fillers, and dry silica sand streams beneath process bins. The enclosed housing retains airborne particulates inside the transfer chute, eliminating dust escape into processing facilities.

Compact 1.5 kW motor drive with EP 315-2 flat belting handling throughputs up to 600 t/h
Double-flange perimeter configuration ensuring tight mechanical joints to chute flanges
Replaceable wear-resistant elastomeric seals maintaining tight containment on fine sand
Engineering match of sealing gaskets, carriage guide wheels, and position sensors by tag

WÖHWA Typ 09, 99, and 089 emergency shut-off gates

Safety shut-off and emergency gates from WÖHWA ensure immediate stream cut-off during feeder servicing or electrical outages. Impact flap gates type 09, spindle closures type 99, and needle gates type 089 protect downstream conveyors from unmetered material spills.

Impact flap gate Typ 09 Schlagschieber providing rapid gravitational material shut-off
Needle gate Typ 089 Nadelschieber utilizing round pins to penetrate coarse aggregate
Spindle emergency gate Typ 99 with manual wheel drive for safe maintenance isolations
Verification of replacement pins, spindle nuts, locking pawls, and seals by machine id

Installation and alignment of WÖHWA SFB 22 belt scales on conveyor structures

WÖHWA SFB 22 conveyor belt scales mount directly onto the longitudinal stringers of plant belt conveyors using an adjustable telescopic frame.

To uphold designated metrological accuracy, the weighing station sits along a rigid straight conveyor run at least five idler pitches away from material loading skirtings. During mechanical alignment, idler concentricity is verified to avoid angular offset across supporting strain gauge assemblies.

Stainless steel direct-acting load cells absorb vertical forces without intermediate pivots, eliminating mechanical play and maintaining zero stability under demanding gravel handling operations.

Zero point calibration of 10.1 RD weigh belt feeders using test weights

Routine calibration of WÖHWA series 10.1 RD weigh belt feeders utilizes an integrated pivoting lever mechanism and factory-verified test weights. Before calibration commences, plant technicians clean the structural frame, pulleys, and polyurethane belt cleaners from adhering sand and gravel fines.

The calibration cycle runs during empty belt travel at stable transport speeds using EP 400-3 belting. The onboard microprocessor controller calculates tare values across a complete belt revolution before the reference mass is engaged, eliminating systemic dosing errors prior to mixer feeding.

Maintenance of WÖHWA 10.3 HD heavy feeders and Typ 089 needle gates

Heavy-duty belt feeders across WÖHWA series 10.3 HD and 10.4 HD operate under constant abrasive exposure beneath primary rock hoppers. Scheduled inspection incorporates ultrasonic measurement of wear liner plate thickness in material impact zones and alignment of lateral skirting rubber seals.

The Typ 089 needle gate mechanism requires routine cleaning of guide combs from jammed rock fragments alongside lubrication of pivot joints.

When bending is observed on individual round pins, technicians replace components using serial numbers from factory documentation to restore tight hopper isolation.

Adjustment of limit switches and roller guides on Typ 01.1 sliding gates

Flat sliding gates from WÖHWA type 01.1 Regular Duty and Heavy Duty control the outlet area of silo throats via motor-driven slide blades. Maintenance procedures include checking carriage travel along hardened guide rollers and adjusting scraper tension around the perimeter.

Inductive limit sensors undergo precise position verification to prevent mechanical impact against frame stops at full open and closed endpoints. Motor-gearbox electromechanical brakes are tested to prevent unintended blade movement from material head pressure.

Seal replacement procedures for WÖHWA Typ 08.1 double-flange sliding gates

Double-flange sliding gates type 08.1 from WÖHWA seal discharge chutes against dust emissions during transfers of fine mineral fillers and dry silica sand. Environmental maintenance involves evaluating the elasticity of polyurethane sealing strips and shaft labyrinth packings.

When sealing effectiveness declines, technicians de-energize the drive, open perimeter access covers, and install fresh elastomeric profiles. Close blade-to-seat engagement stops abrasive dust egress into drive elements and maintains facility clean air compliance.

Integration of WÖHWA weighing terminals into industrial automation networks

Microprocessor weighing terminals from WÖHWA transmit real-time throughput rates, totalized weights, and belt speeds to plant management systems through industrial Profinet, Modbus TCP, and Profibus DP fieldbus interfaces.

Configuring the measurement loop involves scaling analog inputs from strain gauge bridges and tuning digital filter algorithms to damp out conveyor vibration frequencies.

Proper shield bonding on communication wiring alongside isolated power routing safeguards signal integrity against interference during crusher drive starts.
