* German TA Luft regulation: The burner settings and the functioning of the filter equipment must be checked regularly and serviced at least once a year.

DRYER AND RECYCLING DRUM service

Perfectly positioned

Dryer drums for virgin material and recycling material are essential components of asphalt production. They are subject to user-related wear and should be kept at the status quo with targeted service work.

The targeted removal of visible running marks and wear on rollers and rings ensures optimum running of the dryer shell. An even rolling movement with optimum transmission of forces minimises the strain on bearings and guide elements, increasing their service life. At the same time, this reduces the current consumption to a minimum.

The drum service ensures maximum reliability, energy efficiency and economic efficiency.

Our services:

  • advance evaluation of the condition of the drive rollers
  • on site: check of the condition of the frame, rollers, rings and spring plates
  • dressing the drive rollers
  • grinding of the trunnion rings
  • levelling and adjusting of the drive rollers
    (our recommendation: repeating this process each year under production conditions)

MIXER service

For mixing at the highest level

The mixer is the heart of an asphalt mixing plant. In the mixer, the virgin mineral is mixed intensively with the binder and the filler to produce a homogeneous mass. Due to the high strain in terms of wear, weight and transmission of forces, only materials of the highest quality are used to manufacture the mixer.

Our services:

  • complete inspection or partial work
  • drives (replacing motors, gearboxes)
  • agitator (shafts, seals, replacing paddles, etc.)
  • liner wear plates (replacing all wear plates:
    trough, end walls, rotary slides)

WEIGH HOPPER CALIBRATION service

Your direct advantages from our BENNINGHOVEN core know-how

As part of in-house production monitoring, owners of asphalt mixing plants are obligated to calibrate the weigh hoppers annually and document this.

We can carry out the calibration for you as a service based on the appropriate requirements and situation. To do this, we use innovative BENNINGHOVEN measuring equipment that ensures fast and efficient completion.

The measuring system is based on the principle of measuring tractive forces. It consists of an edge stop set and an electronic calibration system. Loading the weigh hoppers with separate, calibrated weights is not necessary. This makes handling very easy, fast and ergonomic.

The calibration system can be used to check and adjust the aggregate, filler, bitumen and RAP weigh hoppers.

Our services:

  • weigh hopper calibration using tractive force measurement, including a report
  • aggregate weigh hopper
  • filler weigh hopper
  • bitumen weigh hopper
  • RAP weigh hopper

DUST COLLECTION SYSTEM service

For a clean performance

Dust collection systems are essential for operating asphalt mixing plants. The dust generated during the mixing process, in particular stone particles and bitumen vapours, have to be extracted and filtered. This is relevant to the design of the plant processes, but is also subject to official regulations in terms of emissions during asphalt production. These regulations are currently being tightened up increasingly in many countries and regions.

Our services:

  • dust emissions measurement* in the stack
  • tightness test with fluorescent powder for localising leaks (if dust values are too high or for recurring official emissions measurements)
  • replacing filter bags

* German TA Luft regulation: The burner settings and the functioning of the filter equipment must be checked regularly and serviced at least once a year.

SERVICE WORK

Your direct advantages from our BENNINGHOVEN core know-how

We manufacture all components ourselves and therefore have a high level of skills in all areas of an asphalt mixing plant. This means we can offer practical support to you as the plant owner in all matters, whether conveyor systems, screens or loading silos.

Our know-how includes:

  • conveyor systems
  • elevators
  • burners
  • screen units
  • weighing systems
  • pneumatics, and much more

Our services:

  • metalworking (e.g. replacing components and spare parts)
  • welding (e.g. lining with wear plates)
  • electrical work (e.g. integration and replacing of electric parts)

INSULATION AND TRACE HEATING service

Using energy sustainably

Our technical insulations meet the highest requirements and are durable and safe. They reduce thermal losses and noise emissions. The insulation materials are also subject to an ageing process during the life cycle of an asphalt mixing plant. Replacing the insulation can therefore make a significant contribution to saving energy.

Our services:

  • replacing insulation
  • spot repairs on the insulation
  • replacing the base heating on the bitumen tank, including the insulation
  • replacing electrical trace heating units

TRAINING COURSES

Good to know – optimum control of the plant

All processes and functions of a mixing plant are controlled with an electronic plant control system. The system offers the mixing foreman an interface with the best possible ease of operation and maximum reliability for plant operation.

At the same time, the plant operator has a high level of flexibility for adjusting the plant to a number of different requirements. This requires taking into account influencing factors such as mixing ingredients, recipe and quality requirements, fuels, current ambient conditions (temperature, humidity) and much more in such a way that quality assurance, reliability and economic efficiency remain ensured.

Correct running of the plant therefore offers great optimisation potential. Regularly training plant personnel can save a lot of money: Energy consumption, minimising wear, preventing damage, efficient and effective maintenance and servicing are only some of these aspects.

Our services (contents and scope can be customised):

  • plant control training*
    • training at the Wittlich factory (in-house)
    • online training on your mixing plant (virtual)
    • training directly on your mixing plant (on site)
  • maintenance and service training*
    • components and regular checks, maintenance and servicing on them
  • workshops for teams

* The training courses can be individually tailored in terms of duration and contents.

PLANT INSPECTION

So everything continues to run smoothly

Based on our varied expert knowledge as a manufacturer and our longstanding experience in supporting mixing plant customers, we have developed a structured plant review together with customers, which we offer as a service product.

Play it safe and use our wear check service. Our field engineers check, assess and record the condition of your plant. You receive independent feedback on any required actions. This protects you against unexpected surprises and helps you to plan any measures in good time. You can keep an eye on the condition of your machine and are alerted to potential failures due to wear early on.

Prevent investment backlog, plan in good time, stay up to date – a good feeling for you and your employees.

Our services:

  • visual inspection of the individual components
  • inspection of wear parts based on checklists
  • a detailed wear and maintenance record
  • advice and support for the required measures
  • a quotation for the genuine spare parts

BENNINGHOVEN 24/7 TECHNICAL SUPPORT

For reliable performance

The BENNINGHOVEN Technical Support (hotline) at our main factory in Wittlich provides support for plant personnel and for service employees on site.

The telephone service offers help for questions regarding plant operation and troubleshooting. It can also help to eliminate faults very efficiently and effectively and sometimes to completely avoid an engineer visit at your site, which would cost time and money.

The Technical Support becomes even more efficient by using remote service and remote access options. For older plants, we recommend very simple retrofit kits, if this is technically feasible.

Our services:

  • 24/7 telephone support with remote access* worldwide
  • database cleansing, database backups
  • repairing control system components
  • retrofitting remote access systems

* Prerequisites for remote access: The required technical systems must be available. Access is possible only after enabling by the customer.
