Stand Alone Metal Chip Processing Systems
Low Cost VD40 Pneumatic Chip Wringing System
The National VD40 compact pneumatic chip wringing system is an economical and effective method for drying and conveying metal chips where there is limited floor space.
The model VD40 chip wringer can be placed directly under the discharge of a single machine tool conveyor or the VD40 can serve multiple machine tools as shown in the following diagrams and photographs. The pneumatic air flow developed by the chip wringer provides a means for conveying "dry" metal chips for a maximum distance of 30-40 feet (9m-12m) to a container.

Wet Chips and Turnings System A
Description of Operation - System "A"
Metal Chips from machining operations are delivered to receiving hopper (RH) from which they are conveyed by a hinged steel belt conveyor (AC) to a vibrating screen (parts separator) (VS) for separation of the occasional tool or part. Chips passing through the screen report by gravity to a horizontal bowl continuous chip wringer (centrifuge) (CW) where residual cutting fluids are extracted and discharged to effluent collection sump (ES). Dry metal chips are discharged via chute (CC) to a container. The entire system is controlled from master control panel (CP) fitted with a programmable logic controller.
Description of Operation - System "A" Options
- A1 Roll Over Cart Dumper: automatically lifts, rotates and dumps metal chips into system receiving hopper (RH).
- A2 Dry Chip Discharge Conveyor: elevates dry metal chips to permit the loading of larger containers.
- A3 Swivel Chutes: permit the distribution of dry metal chips into either of two roll off containers or trucks.
- A4 Conveyorized Effluent Sump: fitted with a small drag conveyor which automatically reclaims fine particulates which have settled from extracted cutting fluids.
- A5 Diaphragm Pumps: deliver drained or extracted cutting fluids to a central collection station.
Wet Chips and Turnings System B
Description of Operation - System "B"
Metal Chips from machining operations are delivered to receiving hopper (RH) from which they are withdrawn by screw conveyor (HF) for delivery to parts separator (PS) for separation of the occasional tool or part, prior to being received by a vertical bowl continuous chip wringer (CW) for extraction of residual cutting fluids. Such fluids as removed by the chip wringer flow by gravity to effluent collection sump (ES) for subsequent disposal. Dry metal chips are pneumatically expelled from chip wringer (CW) using air flow generated within the wringer by abrasion resistant fan blades located within its upper section. Pneumatically conveyed dry metal chips flow via pipeline (PP) to target box (TB) positioned above the collection container. The entire system is controlled from master control panel (CP) fitted with a programmable logic controller.
Description of Operation - System "B" Options
- B1 Roll Over Cart Dumper: automatically lifts, rotates and dumps metal chips into system receiving hopper (RH).
- B2 Two Roll Metal Turnings Shredder: shreds stringy metal turnings into metal chips of a suitable size for effective processing in the chip wringer (CW).
- B3 Swivel Chutes: permit the distribution of dry metal chips into either of two roll off containers or trucks.

- B5 Diaphragm Pumps: deliver drained or extracted cutting fluids to a central collection station.
Wet Chips and Turnings System D
Description of Operation - System "D"
Metal turnings and metal chips from machining operations are collected in containers and dumped by fork lift truck into crusher receiving hopper (CH) from which they are drawn downward into crusher (CR) for size reduction. The crusher is of the vertical shaft, slow speed, high torque design and is fitted with anti-jam and automatic solids rejection provisions. Crushed metal chips are delivered by hinged steel belt (apron) conveyor (AC) to a vibrating screen (parts separator) for separation of the occasional tool or part. Chips passing through the screen report by gravity to a horizontal bowl continuous chip wringer (centrifuge) (CW) where residual cutting fluids are extracted and discharged to effluent collection sump (ES). Dry metal chips are discharged via chute (CC) to a container. The entire system is controlled from master control panel (CP) fitted with a programmable logic controller.

Wet Chips and Turnings System F
Description of Operation - System "F"
Metal chips and turnings are collected in containers and dumped by fork lift truck into crusher receiving hopper (CH) from which they are drawn downward into crusher (CR) for size reduction. The crusher is of the vertical shaft, low speed, high torque design fitted with anti-jam and automatic solids rejection provisions. Crushed metal chips are delivered by a hinged steel belt (apron) conveyor (AC) to a vibrating screen (VS) for separation of the occasional tool or part. Metal chips passing through the screen report to a vertical bowl continuous chip wringer for extraction of residual cutting fluids. Fluids removed by the wringer flow by gravity to effluent collection sump (ES) for subsequent disposal. Dry metal chips are pneumatically expelled from the chip wringer (CW) using air flow generated within the wringer by abrasion resistant fan blades located in its upper section. Chips flow via pipeline (PP) to a target box (TB) for discharge.

Wet Chips and Turnings System J
Description of Operation - System "J"
Metal chips from machining operations are delivered to receiving hopper (RH) from which they are conveyed by a hinged steel belt conveyor (AC) to a vibrating screen (parts separator) (VS) for separation of the occasional tool or part. Metal chips passing through the screen report by gravity to a horizontal bowl continuous chip wringer (centrifuge) (CW) where residual cutting fluids are extracted and discharged to effluent collection sump (ES). Dry metal chips are discharged via chute to helicoids (screw) metering conveyor (HC), discharging into rotary air lock feeder (RAF). Chip discharge from the feeder falls into pipeline (PP) where air flow generated by pressure blower unit (PBU) carries the material downstream to target box (TB) where flow velocity is dissipated, allowing metal chips to discharge by gravity into a container or truck.
