Unlike low density cleaners that operate after pulp dilution, High Density Cleaners work on pulp with a consistency of 3-6% right after raw material pulping, which eliminates the need for extra dilution before impurity removal and saves energy that would otherwise be spent on re-concentrating pulp later. Leizhan’s high density cleaner is optimized with a specially designed tapered cyclone body and adjustable vortex generator, which creates a stronger centrifugal separation force that can efficiently separate dense impurities such as scrap iron, sand, gravel, metal fragments, and glass shards from the fiber slurry. These heavy contaminants, if not removed early, would cause irreversible wear to beating equipment, paper forming wires, and press rolls downstream, leading to more frequent maintenance, shorter equipment lifespan, and unexpected production shutdowns.

From the perspective of practical operation and maintenance, Leizhan’s High Density Cleaner is designed for user convenience. Its modular structure allows quick disassembly for cleaning and internal part replacement, and the wear-resistant inner lining extends the service interval to over 2 years under normal operation, reducing maintenance downtime. Most models can also be connected to an automatic slag discharge system, which removes collected contaminants continuously without interrupting production, fitting perfectly into fully automated pulp processing lines.

As one of the core products of Leizhan Papermaking Machinery, their high density cleaner has been installed in hundreds of pulp and paper mills across more than 30 countries, earning consistent feedback for its stable performance and low operating cost. For both new mill construction and existing production line upgrades, Leizhan’s high density cleaner is a cost-effective choice that lays a solid foundation for high-quality pulp production.
