Where compromise is not an option:
From laboratory scale up to 10,000 litres working volume. Our machines and custom systems are tailored specifically to your requirements.
Modular, versatile, powerful.
Discover our machine types.
Double-Z / sigma kneaders
For masses of widely varying viscosities. Product discharge options: tilting, bottom discharge or via discharge screw.
Planetary mixers & planetary dissolvers
For mixing and dispersing viscous, pasty or highly viscous materials.
Dry mixers
Helical ribbon and ploughshare mixers for homogeneous mixing of powdery, fine-grained solids.
Custom systems
Customer-specific and project-based.
Configured for your material.
Every machine is equipped with the options your process demands.
ATEX, FDA and GMP compliant
ATEX directive for explosive atmospheres, FDA-compliant for food and pharmaceutical contact, GMP- and EFSA-compliant design and documentation on request.
Heating and cooling right into the tool
Double jacket on trough, side walls, extrusion tube, lid and, on request, right into the kneading blades and discharge screw. Precise temperature management even with exothermic formulations; heating and cooling media to suit the process.
Void-free under vacuum
Vacuum technology with pre-vacuum chambers for void-free, reproducible masses and clean, void-free discharge. Pressure and temperature monitoring in the product chamber.
PLC, formulation and traceability
Freely programmable PLC control system, formulation management and complete data logging for batch release. Connection to higher-level control systems possible.
Special materials and hardened surfaces
Abrasion-resistant hard facing, special alloys and coatings for highly abrasive masses. Mechanical seals and special sealing systems for long service life and leak-free processes.
Minimal dead space and fast cleaning
Trough and blade geometries with minimised dead space and precisely defined clearances, tilting and retractable troughs (hydraulic or manual) and CIP-capable versions for short changeover and cleaning times.

We deliver superiority in the process.
On purchase price, the competition often wins. On everything that comes after, you win with Linden. The difference lies in what cannot be copied: engineering, validation, availability and service across the entire life cycle.
In-house design engineering & production
Sizing, design engineering and production from a single source, Made in Germany. Those who build the machine also understand your process and take responsibility for it from the first sketch to acceptance.
Total Cost of Ownership
It is not the purchase price that counts, but service life, energy consumption, wear, rejects and downtime. Robust, process-reliable design and wear protection lower your costs for years.
Validated engineering
Every series is tested on real material in our in-house Technical Center and designed for reliable scale-up. The production plant builds on the findings gained.
After-sales & availability
Spare parts, conversions and retrofits across the entire life cycle. Low-maintenance design and fast service keep your system available in continuous operation.
Your formulation determines the machine.
Not the other way round.
