Innovative machines and processes for demolition, construction and foundation engineering are Kemroc’s core competencies and have been for 25 years. The German manufacturer of hydraulic milling attachments for excavators will be celebrating its anniversary in front of an international audience with the slogan, ‘25 Years German Rock Cutting Solutions’. At bauma 2025, the company will be exhibiting at booth FN.1017/8 in outdoor area North. Hovering over the booth and visible from afar, will be the familiar large orange balloon with the Kemroc logo.

Under the balloon, demonstrations will be taking place, accompanied by the well-known German TV presenter Jan Kunath. The main action will be on the left hand side of the exhibition stand. Here, a crawler excavator will alternate between a chain cutter attachment, a bullhead milling attachment and a diamond saw attachment from the current range designed for demolition and construction applications. The patented chain cutter is a cutter chain with carbide tipped teeth that runs between two cutter drums. This allows the attachment to excavate trenches in soil and rock to exactly the required width without leaving a ridge in the space between the two cutter drums which the excavator operator must remove with sideways movements. 

The ‘EKT’ range of drum cutter attachments is designed with a distinctive feature: they can be retrofitted with a cutter chain if required. The ‘KRC’ range of bullhead milling attachments, with their cutter drum heads arranged at angles to each other, produce an almost complete milling pattern when penetrating rock and soil without being fitted with a central cutter chain. A model from the ‘KDS’ range will also be shown working on the crawler excavator. The diamond saw attachments can cut through rock, concrete, plastic, wood, and aluminium. When used in conjunction with rotation modules from the ‘KRM’ range, which will also be on demonstration, the milling attachment can correctly align for the application at hand. 

At the centre of the booth, Kemroc will be exhibiting other models. Visitors can test, view and compare these attachments at close range. In addition to models from the KRC and KDS range, there will also be an attachment from the ‘DMW’ range of cutter wheels. These attachments, fitted with double motors, can cut hard rock and reinforced concrete with high production rates. Also on display will be examples from the ‘KR’ range of rotary drum cutters with helical gears. These have been designed for use on short boom excavators working in confined spaces, such as in tunnelling, as well as for low vibration and low noise demolition of reinforced concrete structures.

At bauma, Kemroc will also be presenting itself as an innovative manufacturer of hydraulic motors, designed and manufactured inhouse specifically for use on Kemroc attachments. Compared to motors from other manufacturers, they are said to have a higher flow rate, are more compact in design and generate higher torque. 

The right-hand side of the Kemroc booth will contain exhibits from the Kemsolid division with attachments dedicated to foundation engineering. This includes exhibits of the ‘KRX’ range of power tool drives comprising of attachments for milling, drilling, and mixing covering a wide range of foundation engineering applications. The core offering here being the ‘KSI’ process for soil stabilisation (Kemsolid Soil Injection). In this process, a standard excavator uses a mixing attachment capable of milling, mixing, and injecting (FMI process) to descend into the soil with a cutter chain while mixing the soil with an injected binder suspension. After hardening, the soil is transformed into a homogeneous, dense, stable, load bearing earth based concrete structure. KSI mixing attachments are used for soil waterproofing and soil stabilisation applications as required in road building projects. 

On display for the first time at bauma 2025 will be the KSI 16000 Twin which is a soil mixing attachment with a double blade and a modular mixing depth of up to 8m. This is particularly suitable for soil consolidation in the construction of new or upgrading existing high speed railway lines.
