Complete LOCC Pulping System in Kraft Production Line

The complete LOCC pulping system is a core component of any modern paper manufacturing line, specifically designed to process old corrugated containers into high-strength kraft and linerboard pulp. This paper mill machinery integrates a heavy-duty chain conveyor with a bale breaker, a D-type continuous hydrapulper with a large extraction screen, and an efficient hydrapurger for early removal of heavy and light contaminants. The paper production equipment also includes a drum screen, ragger, rope cutter, and high-density cleaner to ensure maximum fiber recovery and minimal downstream wear.

A multi-stage coarse screening and fine screening section, combined with centrifugal cleaners and fractionation screens, delivers exceptional pulp cleanliness and fiber fractionation for optimal sheet properties. The paper making line further incorporates a double disc refiner for precise beating control, ensuring superior strength development. With a closed white water recovery system, this paper processing line significantly reduces fresh water consumption and environmental load. Designed for continuous, trouble-free operation, this complete pulping system enhances the efficiency of any paper machine producing packaging grades.
