ZKL650‑11/250 Large‑Capacity Continuous Vacuum Feeder

Boost Your Powder Conveying Efficiency With Reliable Continuous Feeding Technology

In modern food, chemical and pharmaceutical manufacturing, stable, dust‑free powder material transfer directly determines overall line output and workplace safety. Our ZKL650‑11/250 Large‑Capacity Continuous Vacuum Feeder is engineered for medium‑volume powder handling, specially optimized for flour and similar fine bulk solids. This vacuum conveying machine eliminates manual dumping, reduces dust pollution and supports non‑stop continuous feeding for your downstream processing equipment.

Core Technical Performance

Running on standard 380V / 50Hz industrial power supply, this unit delivers a conveying capacity ranging from 2000 kg/h to 4000 kg/h. This rating is tested under real‑world working condition: flour conveying with 2‑meter vertical lifting height plus 3‑meter horizontal transportation distance. The working operating pressure stays within 0.6‑0.8 MPa, matching most factory compressed‑air infrastructure.

When configured with 0.6 MPa air pressure and 15‑second backflush interval, the minimum air supply requirement (excluding silo vibrator consumption) reaches (325+30) L/min. The built‑in GT08 silo vibrator consumes 112 L/min compressed air to prevent powder bridging and material sticking inside the 200L stainless‑steel hopper. The material hopper adopts 2.5 mm stainless‑steel plate for long‑term wear resistance; its effective working volume is 200 liters to guarantee steady material buffer during non‑stop operation.

Premium Component Configuration

The power core adopts a 11 KW 2GH820 vortex blower, providing consistent negative‑pressure suction force for continuous material pickup. Customers can select from four interchangeable filter cartridge options according to material features: 34 pieces stainless‑steel filter cartridges Φ50×500; 34 pcs titanium sintered filter cartridges; 19 pcs bag filter cartridges Φ75×600; or 34 pcs PE‑membrane filter cartridges Φ50×500. Multiple filter material choices help you handle sticky powder, abrasive particles or high‑purity food‑grade materials.

A complete automatic pulse back‑blowing cleaning system maintains filter cartridge performance without frequent manual disassembly. This system includes DC24V pulse valve, AFR2000 oil‑water separator and Φ159×600 backflush air manifold. Periodic pulse air blast blows accumulated powder off filter surfaces, extending filter service life and avoiding suction‑power decline caused by filter blockage.

For stable material discharging, the machine equips XF250 airlock fan (1.5 kW) DN250 rotary valve as discharge device. A TD25‑DC24V level gauge monitors real‑time material level inside the hopper, auto‑adjusting suction and discharge rhythm to prevent overflow or empty‑running.

The delivery scope includes 5‑meter Φ63 PVC steel‑wire suction hose and 3‑meter Φ76 negative‑pressure hose, flexible for on‑site layout. The integrated control box uses self‑developed circuit board, Taiwan Mean‑Well switching power supply, Chint brand electrical parts and SMC solenoid valve for stable long‑shift operation.
