Asphalt & Bitumen
A retrofit from Benninghoven modernizes plants from all manufacturers
Retrofit solutions to modernize existing asphalt mixing plants make sense for lots of reasons – and are often more beneficial than investing in new equipment. In densely populated regions, a retrofit may well be more or less the only option, as getting new local authority consent would involve a complex process and the outcome would be uncertain.
When an existing plant is renewed, on the other hand, new consent becomes completely superfluous in many countries. Benninghoven is the partner for mixing plant operators in all retrofit projects – regardless of which manufacturer originally installed the old plant. In the process, customers benefit from the expertise and fairness which characterize Benninghoven.
Complete retrofit solution from a single source
From design to technical implementation to realization on site: Benninghoven experts from the Wirtgen Group subsidiaries accompany the retrofit process all the way from establishment of contact to final acceptance. They also make direct contact with the main factory. This is of particular value to plant operators, because no two mixing plants are alike. A great many solutions have to be adapted individually or even worked out from scratch to make the plant future-proof. To make sure everything comes together perfectly at the end, the procedure is divided into three steps: development of a joint retrofit plan, technical investigation and implementation at the main Benninghoven factory, implementation of the new technology on site.
Approaching retrofit projects with a plan from the outset
Every Benninghoven retrofit project starts with an on-site meeting. A team from the Wirtgen Group subsidiary which
looks after the customer visits the customer with proven Benninghoven experts. A written record is made of the plant technology in situ and of all the desired changes, with Benninghoven planning manuals a helpful tool in this process. Photos of the plant and of the components to be renewed are also taken at this initial meeting.
Individual customer solutions – delivered in turnkey form
“A retrofit from Benninghoven is more or less a turnkey solution,” says Markus Bühl, area sales manager for Benninghoven products at the Wirtgen Group subsidiary in Augsburg. A commission which supports this statement is the project to retrofit the asphalt mixing plant in Mintraching, owned by Guggenberger GmbH, where the aim was to renew a Benninghoven BA 4000-type plant. The focus in this case was to increase the performance and efficiency of the plant, involving among other things replacement of the dryer drum and the burner. It soon became clear that a standard drum would not fit. Markus Bühl took this challenge back with him to the main Benninghoven factory to develop a solution with the Technical Office.
Technical investigation - Working out an individual solution for the customer
Following on from the on-site meeting at the plant location in Mintraching, the Wirtgen Group team discussed the requirements of Guggenberger GmbH at the main Benninghoven factory. “With this plant there was a whole range of requirements which off-the-peg solutions were unable to help with,” says Jörg Genetsch, expert in drying and dust collection technology in Benninghoven’s Technical Office. “However, we’re used to that with retrofit projects and can implement even this kind of project economically for the customer.”
Retrofit solutions from Benninghoven are developed in close collaboration with customers and users.
