Lanner Anlagenbau GmbH

Chip processing systems from Lanner

Industry 4.0 in chip processing

- project kößler technologie GmbH -

A fully automated project to process steel chips was realized at the company kößler technologie GmbH that is an important German automotive supplier.

Every day 45.000 kg steel chips are processed with this Lanner system without any manpower.

In the following article you find a detailed description of this fully automated and networked chip processing system:

All the chips are collected in chip carts directly at the tooling machine and transported to the Lanner system by a driverless transportation system. At this stage the automated operation of the whole chip processing system starts:

The chip cart dumper feeds the hydraulic chip crusher. The long and short chips are crushed in several steps in the vertical working chip crusher. Afterwards the broken chips fall into a conveyor. Mistakenly initiated tramp metals like e. g. bar ends are separated automatically.

Advantages of the Lanner chip crusher:

• vertically working chip crusher for a precise and defined crushing solution
• crushing tools made of high quality and hardened tool steel for a long product life
• big tramp metal ejector
• wear parts are easy to regrind and exchange

The conveyor with integrated tank which is placed after the chip crusher transports the small chips through the screener into the self-cleaning centrifuge. The screener separates the mistakenly initiated tramp metals that only the free flowing steel chips are entering the hydraulic lifting bottom centrifuge.

In the centrifuge the solid liquid separation happens. An interval-driven lifting bottom pushes the chips in defined cycles onto the slot sieve that is at the wall of the drum. The dry chips leave the machine downwards and the liquid exits through the slot sieve and flows into the tank.

Advantages of a Lanner lifting bottom centrifuge:

• highest drying level of the chips at years of continuous operation
• residual moisture < 1 % possible
• self-cleaning principle of the lifting bottom
• covered with highly wear-resistant material, fast and easy changeable

The drag link conveyor transports the centrifuged chips to another “distribution conveyor” which is equipped with four swivel chutes. They distribute the dry and free flowing chips into eight containers.

Probes recognize as soon as one container is full or not present and the swivel chute feeds the next container. If the container is full an email is automatically sent to the responsible employee who informs the recycling company to pick up the container.

Advantages of the Lanner chip processing system:

• sophisticated solutions
• permanent development of the products
• high reliability of the technical systems
• consultancy, construction and production are provided from one source
• individual and exact matching customer solutions and systems
• short amortization
• highest drying level of chips in years of continuous operation
• fast and reliable service
• decades of availability of spare and wear parts

Like the company kößler many well-known companies count on the quality from Lanner in continuous and three-shift operation, without breakdowns or big maintenance works.

This sample of the company kößler shows very good that Lanner is up to date and familiar with the topic industry 4.0.

It does not matter if you have a big or small chip amount:

Lanner Anlagenbau GmbH is the ideal contact partner in the field of chip and grinding sludge processing. At Lanner you receive single components and individual complete solutions in highest quality.

The German company Lanner Anlagenbau GmbH, founded more than 30 years ago, has a leading position in the world market in the field of chip processing because of its quality, competence and reliability.

The product range of this company includes also three different types of centrifuges for the separation of solids and liquids:

• Batch wringer
• Parabolic centrifuge
• Lifiting bottom centrifuge

Batch wringers from Lanner are suitable for the manual and half-automatic de-oiling or drying of chips and grinding sludge. The basket can be elevated into the centrifuge using a lifting hook. When the drum is placed into the centrifuge an individually set centrifuging time begins to run. After completion of the centrifuging process, the drum is taken out and the process can be repeated with the next wet material. In this centrifuge it is also possible to clean and coat parts. Batch wringers are constructed for a long lasting continuous operation. The electro-magnetic lid locking, an unbalance detection switch and the standstill control provide maximum operational safety.

Optional accessories are available:

Adjustable drum speed, crane support with pivot arm or an electric chain host, heating, tank, transport cart for the drum or customized carrier e. g. for boxes or workpieces. Even customized models in stainless steel, EX protection or fully automated machines are available on request.

Lanner parabolic centrifuge: This type of centrifuge is made for the fully automated operation and is suitable e. g. for using directly at the central system or the tooling machine. The wet and free flowing chips enter the parabolic centrifuge through the infeed hopper and fall into the drum. The centrifugal force presses the chips at the drum wall and they move upwards onto the slot sieve. At this point the coolant is separated from the chips. The dried chips are carried over the edge of the drum and leave the centrifuge downwards into a chip cart or discharge conveyor.

The regained liquid can be returned for further treatment into the machine-tool or can be pumped into a coolant-cleaning system.

This economical alternative to the lifting bottom centrifuge can optionally be expanded by a locked inspection lid in the cover, heating, slot sieve cleaning or air pressure emptying.

The patented lifting bottom centrifuge from Lanner is the best choice concerning regaining maximum coolant and processing reliability. It is equipped with a lifting bottom which moves in cycles and is also suitable for very fine materials like grinding sludge because of the self-cleaning principle. In the fully automated operation the wet chips / sludge fall into the drum of the lifting bottom centrifuge. Here they meet the rotating lifting bottom and the high centrifugal forces press them at the wall. The hydraulically activated lifting bottom moves the chips / the sludge upwards to the slot sieve where the liquids are separated from the solids. After a few lifting cycles the centrifuged chips / sludge are carried over the edge of the drum and leave the centrifuge downwards. The regained coolant can be returned to the production or pumped into another system for further treatment.

The lifting bottom centrifuge offers the best possible de-oiling in the universal operation.

Low maintenance costs, high reliability and highest availability stand for these types of centrifuges.

These centrifuges can be perfectly integrated in chip processing systems. At the product description you find information about chip processing systems and the product range from Lanner. Visit us at our booth (hall 7 stand 182).

Chip crusher from Lanner:

Made for very hard cases

Lanner Anlagenbau GmbH is specialized in the development and delivery of chip processing systems for more than 30 years. In this time the company grew from an one-man-working company to an international, medium-sized company. Highly qualified employees offer innovative and patented developments and established Lanner at the global market because of various solutions and references.

Long and woolly chips result from many treatment processes, often have a big volume, are not easy to transport, are difficult to process and cause difficulties in the logistics. The best solution for these issues are chip crushers from Lanner:

The volume of the coolant containing or dry long and woolly chips can be reduced up to 80 % by breaking them. A chip conveyor or chip cart dumper puts the chips into the infeed hopper. Of course, the crusher can also be placed directly under the tooling machine.

Because of the force of gravity the chips are pulled downwards by the knife arms to the tearing block in the vertical working chip crusher – in this section the pre-crushing happens. A rotating knife head with hardened crushing tools moves the long and woolly chips to the tearing blocks which are mounted fixed in the grinding hopper.

Afterwards the pre-crushed chips fall into the crushing mill where they are crushed again to a minimum size. This chip crusher also minimizes really tough chips. The biggest advantage of Lanner chip crusher is the integrated tramp metal ejector. Here mistakenly initiated tramp metals are sorted out. This feature is also included in the smallest machine!

The chip crusher can be expanded by a hydraulic drive, special material for life extension or an inspection cover in the hopper. For special customer requests e. g. different types of material Lanner can offer different types of grinding mills to optimize the volume reduction.

Another advantage is that wear parts can be re-grinded easily with standard tools. Changing of wear parts is possible within very short time. Thanks to the robust construction chip crushers from Lanner are working around the clock for decades. The vertically working chip crusher needs very few energy in comparison to single or various draft shredders.

Lanner chip crushers can optionally be integrated in chip processing systems.

As an international market leader and supplier of complete processing systems for chips and grinding sludge Lanner Anlagenbau GmbH contributes significantly to a considerate and economic treatment of raw materials. This German company is specialized in single components and systems for chip and grinding sludge processing. In this process there are not only regained clean and dry chips but also the coolant which can be reused. Besides several centrifuges, chip crushers and complete systems Lanner Anlagenbau GmbH also offers briquetting presses. In the following article you find a short functional description:

The coolant containing chips or grinding sludge are put into the infeed hopper of the briquetting press. A dosing screw transports the material in defined quantity into the pressing chamber. Laser probes monitor the dosage. A specialized high pressure cylinder (with pressing capacity of up to 500 bar) compresses the chips or the sludge to a dimensionally stable briquette. The briquette has a very high density and low residual moisture.

While the chips are compacted the coolant is pressed out and can be reused in the further process circle. A tank under the briquetting press catches the separated coolant. The tank is equipped with a discharge pump and a probe according to WRA (water resources authority). The whole briquetting press stands on a tub which is also made according to WRA.

This briquetting press includes a control cabinet which is also made by Lanner.

Optionally the briquetting press from Lanner can be expanded by a chip crusher with tramp metal ejector. With this option also long and woolly chips can be treated.

To get an even better result concerning the residual moisture it is also possible to centrifuge the chips or sludge before briquetting. With Lanner centrifuges a residual moisture of less than 1 % is possible. (Further information concerning centrifuges you find in the product description “Centrifuge techniques”).

A briquetting press can be connected to a complete chip processing system with e. g. chip crusher, screener and centrifuge.

The chip crusher minimizes the volume of the long and woolly chips. The screener separates reliably the spare parts from the crushed chips. The free flowing chips can then enter the centrifuge. At this stage the separation of solid and liquid happens. The processing by centrifuge reaches a maximum drying result (without thermal drying) and because of the briquetting the volume of the chips or grinding sludge is minimized immensely. This combination makes sure that all occurring chips can be pressed to a high quality briquette, a maximum of coolant is regained and a perfect re-melting is guaranteed.
