Ragger is used for coarse screening and cleaning and match with hydrapulper, make contaminants in waste paper such as wires, strings, plastics, yarns and alike twine continuously during the running of hydrapulper, forming a rope and pulled out and discharged. Thus the furnish is preliminarily cleaned. The machine has advantage of higher work efficiency, lower energy consumption, simple structure and easy to operate and maintain, etc.
Grapples are used in continuous pulping system with lifting equipment to take heavy and light contaminants out from the sediment well. Grapple is mainly made of en air cylinder, four tines and a connecting rod. Grapple and sediment well work together to form a cleaning system. When grapple goes down, tines are opened to the biggest size. When drop above pulp level in sediment well it can takes out light impurities, while under pulp level it can takes out heavy impurities. The rated loading of grapple reaches 300kg.
Rope cutter is a coarse screening and cleaning equipment, working together with hydrapulper and ragger. The rope fromed by winding contaminatns like wires, strings and plastics, etc. by ragger will be dragged out by ragger, and then cut by rope cutter to desired length and finally carried way.
