Chip reducers

KNOLL chip reducers cut metal and plastic chips to bulk material quality. The reducers can be installed on machine tools or at central collecting points. Depending on model, horizontal or vertical chip feed is possible, together with faulty part ejection in some applications.

Provided chip reducer with vertical chip feed

 

Areas of application

KNOLL chip reducers ZV, ZVD and ZVDD are machines for reducing metal and plastic chips. The chip feed is done vertically from above.

  • Decentralized use on processing machines (retrofittable)
  • Central use thanks to provision at collection points
  • For volume reduction for improved bearing and transport properties of wool and winding chips
  • For pre-treatment of the chips as pre-requisite for centrifuging, briquetting, melting, pumping, suction, etc.

Properties

Benefits

Suitable for different types of chips

Many application possibilities

Wide, insensitive cutter

Great durability

Intake behavior regardless of the chip form

Many application possibilities

Flexible, changeable toolbox system

Easy modification

Easy, robust, and service-friendly layout

Easy maintenance

Intelligent control

Great process reliability

Multiple sealing of the bearing units

Great stability

Low energy requirement

Low energy costs

Main functions

  1. Feeding of the chips in the feed hopper
  2. Pulling in of the chips between the rotating cutter shaft and the angled infeed slide or fixed cutter
  3. Crushing of the chips between the rotating and fixed cutter
  4. Limitation of the chip lengths with screen insert with different hole sizes or without screen insert

Variants

  • Double-faced blades (-J): for large quantities of chips and high reducing quality
  • Two-headed blades (-Z): with occurrence of problem parts and different types of chips
  • Single shaft: for small bunches of chips and low to medium throughput
  • Double shaft: for large or compressed bunches of chips and high throughput

Combination possibilities 

For other requirements, on request we can combine the chip reducers with

  • Chip conveyors for feeding and removing the chips
  • Frames for holding chip wagons
  • Return pumping stations of chips and coolant lubricants to the central plant
  • Extraction stations for transport of chips to the central plant
  • Centrifuges and briquetting systems for further treatment of the chips
  • Lift-tip devices for feeding the chips to central collection points

Integrated chip reducer with horizontal chip feed

 

Areas of application 

KNOLL chip reducers ZH-J and ZHV-J are machines for the reduction of metal and plastic chips. Chip feed is done horizontally.

  • Especially as integrated component of the return pump station RIK
  • Decentralized use on processing machines with close-to-floor chip feed via screw conveyor
  • For volume reduction for improved bearing and transport properties of wool and winding chips
  • For pre-treatment of the chips as pre-requisite for centrifuging, briquetting, melting, pumping, suction, etc.

The chip reducer ZHV is a component of the machine-integrated pump-back station RIK. It is installed if longer chips or chip balls are produced during machining operations and a screw if sufficient for removing the chips. After pumping back, the chips are of the quality necessary for further processing in centrifuges or presses.
