ZKL800‑15/300 Large‑Capacity Continuous Vacuum Feeder

High‑Throughput Vacuum Conveying Solution for Large‑Scale Powder Production Lines

For large‑volume manufacturing plants processing bulk powder raw materials, ordinary small‑size feeders become bottlenecks limiting overall production output. Our ZKL800‑15/300 Large‑Capacity Continuous Vacuum Feeder is a heavy‑duty continuous vacuum feeding unit built for high‑tonnage powder transfer. It is widely deployed for flour, starch, chemical powder and other bulk solid raw‑material feeding tasks for large‑capacity mixing, extrusion and packaging lines.

High‑Output Core Parameters

This heavy‑duty feeder works with standard 380V 50Hz industrial power grid. Under standardized test condition (flour material, 2 m vertical lift, 3 m horizontal run), its conveying capacity hits 3000‑6000 kilograms per hour, which makes it perfectly match high‑speed continuous production workflows. The system operating pressure range keeps 0.6‑0.8 MPa. At 0.6 MPa supply pressure and 15‑seconds back‑flush cycle, its minimum compressed‑air consumption (excluding bin vibrator) is (816+50) L/min.

The material receiving hopper features 400L effective volume, constructed by 3.0 mm thick stainless‑steel plate to endure heavy‑load continuous operation and material impact. Larger hopper capacity supplies sufficient material buffer for high‑speed discharging and reduces frequency of material‑supply fluctuation. Fitted GT8 bin vibrator consumes 112 L/min compressed air to eliminate arching and bridging phenomenon for poor‑flowability powders. A TD100 (DN25‑24V) level sensor precisely tracks material stock inside the large hopper and realizes closed‑loop automatic feeding control.

Heavy‑Duty Hardware & Diversified Filter Options

Different from vortex‑blower‑type small models, this high‑capacity machine adopts 15 KW RS125 roots blower as negative‑pressure power source. Roots blower delivers stable large‑volume negative‑pressure airflow, maintaining strong suction performance even under long‑distance or high‑elevation conveying scenarios.

To match high‑flow working condition, the filter chamber supports multiple filter‑element configurations for different material properties: 48 pieces stainless‑steel filter elements Φ60×500; 48 pcs titanium sintered filter elements; 26 pcs pleated filter elements Φ60×500; and 48 pcs PE‑membrane filter elements Φ60×500. Whether you handle food powder, easy‑clogging fine chemical powder or corrosive raw materials, you can select corresponding filter media to optimize filtration effect and service life.

The automatic filter cartridge back‑blowing cleaning assembly contains DC24V pulse valve, AFR3000 air‑water separator and Φ219×800 backflush air manifold. Powerful pulse compressed air periodically blows off powder cake attached to filter‑element surface, preventing filter clogging in long‑hour non‑stop running and preserving stable suction performance day after day.

Material discharging relies on XF300 air shut‑off fan (1.5 kW) DN300 rotary airlock valve. The enlarged‑size rotary valve enables higher volumetric discharge rate to coordinate with the 3000‑6000 kg/h high conveying throughput. Standard supply accessories include 5‑meter Φ76 PVC steel‑wire suction pipe and 3‑meter Φ89 negative‑pressure pipe, supporting flexible field pipeline arrangement.

The whole electrical control system consists of self‑designed control circuit board, Taiwan Mean‑Well switching power supply, Chint series electrical components and SMC solenoid valve. The control cabinet integrates full automatic feeding, level‑linkage control and pulse‑cleaning logic, minimizing manual intervention during production operation.
