JS1500 Twin-Shaft Forced Concrete Mixer

JS1500

Twin Shaft Concrete Mixer

The JS1500 is a medium-to-large-scale batch production mixer. It features a significantly increased drum volume, widened dual mixing shafts, and an increased number of blades, resulting in a large material mixing capacity and high single-batch mixing efficiency. The entire machine utilizes a heavy-duty steel structure base, thickened wear-resistant liners, and overall heat treatment. An independent external lubrication station at the shaft end ensures a stable grease supply for continuous high-load production. Its fully enclosed dustproof design allows for 24-hour intermittent full-load outdoor production, making it a standard core unit for mobile mixing plants.

Highlights of JS Series Concrete Mixer

Mixing efficiency and uniformity

Twin-shaft mixers, through combined motion (shearing, extrusion, and tumbling), ensure that concrete reaches a highly homogeneous state within 30-45 seconds, and the mortar density variation coefficient can be controlled within 0.8%, effectively guaranteeing the strength stability of the concrete.

Durable structure and easy maintenance

Core components of the equipment, such as blades and liners, are generally made of high-chromium alloy wear-resistant materials, significantly extending their service life. The rational structural design concentrates material distribution between the two shafts, reducing wear on blades and liners. Furthermore, the modular design and openable cylinder make routine inspections and blade replacements more convenient, effectively shortening equipment downtime.

Wide range of operating conditions

This machine boasts excellent adaptability to various working conditions, easily handling a wide range of mix proportions from plastic concrete to dry-hard concrete. Its powerful mixing capability ensures uniform mixing even with special concrete containing fibers or other admixtures, preventing fiber clumping or material segregation.

Production efficiency and unloading performance

Featuring a large-diameter bottom-opening discharge design, the twin-shaft mixer can quickly and thoroughly discharge the mixture within seconds, leaving extremely low residue in the tank. This not only improves the efficiency of single-batch operations but also effectively avoids cross-contamination between different batches of concrete, ensuring the stability of product quality.
