EX-J Series Horizontal Cooling Mixers

Round Barrel Type – High-Performance Cooling Technology

Designed in Austria  |  Manufactured in China (Shanghai & Nanjing)  |  After-Sales Service: USA • Middle East • EU • Asia

EXTRUTEX proudly presents the EX-J Series Horizontal Cooling Mixers – the latest generation of round-barrel high-speed cooling mixers developed through close cooperation with our long-term technology partners who possess decades of expertise in thermal (heating/cooling) mixing systems.

Combining Austrian engineering design principles with precision manufacturing in our two state-of-the-art factories in Shanghai and Nanjing, the EX-J series delivers outstanding process reliability, exceptional durability, and measurable productivity gains for compounders and processors worldwide.

Complete Product Description

The EX-J Series represents the pinnacle of modern horizontal cooling mixer technology. Engineered specifically for the efficient cooling phase of high-speed mixing processes, these round-barrel machines are ideal for a wide range of materials including PVC dry-blends, masterbatches, engineering plastics, rubber compounds, powder coatings, food ingredients, and specialty chemical formulations. The horizontal round-barrel design ensures optimal material flow, excellent heat transfer, and uniform temperature distribution throughout the batch.

Through continuous collaboration with experienced partners specializing in high-speed thermal mixers, EXTRUTEX has integrated the most advanced process technologies available today. Every EX-J mixer is built to deliver consistent cooling performance, reduced cycle times, and superior product quality while minimizing energy consumption and maintenance requirements.

Superior Mixing Tools – Engineered for Longevity

At the heart of every EX-J mixer are the specially designed mixing blades. Manufactured from high-grade SKD 11 tool steel, these blades offer outstanding anti-abrasion properties. Compared with conventional blades produced by deposition welding, the service life of EXTRUTEX SKD 11 blades is approximately twice as long. With a thickness of less than 20 mm, the blades are lightweight yet extremely robust. Replacement is remarkably simple and can be completed in under five minutes, dramatically reducing downtime and maintenance costs.

Intelligent Discharge System

Each EX-J mixer is equipped with a fully interchangeable discharge valve that is engineered for rapid and thorough cleaning. The valve design eliminates residual material build-up and ensures complete batch discharge without contamination risks. This feature is especially valuable when frequent recipe changes or strict hygiene standards are required.

Dust-Tight Feeding & Vibration-Free Operation

The feeding system has been carefully optimized to allow easy addition of additives, pigments, stabilizers, or other secondary materials during the cooling cycle. A precision-engineered sealing system prevents any powder leakage or dust emission into the production environment. Combined with a balanced rotor design and heavy-duty construction, the mixers operate with virtually no vibration, protecting both the machine structure and the surrounding plant infrastructure.

Measurable Process Benefits

Thanks to the combination of efficient cooling geometry, optimized blade design, and reliable discharge, processors using the EX-J series typically experience up to a 30 % increase in overall process efficiency. Cycle times are shortened, energy consumption per kilogram of product is reduced, and the need for intermediate cleaning or reprocessing is minimized. The net result is lower production costs and higher throughput without compromising product quality.

The robust construction, high-quality components, and thoughtful engineering details make the EX-J series suitable for continuous industrial operation under demanding conditions. Whether installed as a stand-alone cooler or integrated into a complete heating-cooling mixing line, these machines deliver consistent, repeatable results shift after shift.
