Haver & Boecker launches ROTO-LOCK dosing unit

Published by
World Cement,


The Haver & Boecker Machinery Division has put SEAL technology in connection with the new dosing device, ROTO-LOCK®. Due to clean filling, customers can achieve marketing, sales, and profit increases, and higher machine operational availability leads to a higher output. Overall operating and spare part costs are reduced.

SEAL technology for clean valve bag filling

In the SEAL process, a sleeve in the specially-designed filling spout inflates at the beginning of the filling process and seals the valve bag so that no bulk material can escape. After dust-free filling, the bag valve is ultrasonically welded shut.

The compact and fully-closed bag provides a clean working environment and improved health for all employees at the plant, throughout the logistics chain, and for end customers. Clean filling increases process reliability and reduces wear and tear, as well as production downtime that arises due to cleaning, maintenance, and repair works. The clean and attractive appearance also has a positive impact on the company and product image.

Cleanliness increases machine availability, reduces operating costs, and keeps capacity utilisation consistently high. Safety also plays an important role. The ultrasonically sealed packaging protects the environment from possible contamination and promotes safety at all stages of the logistics process. It also protects the filled bulk material from product contamination, removal, and illegal product theft.

The SEAL technology can be retrofitted to all existing Haver & Boecker valve bag packers purchased after 2000.

The ROTO-LOCK dosing unit

The effectiveness of the SEAL technology is increased through the use of the new ROTO-LOCK unit. This module is designed for dosing fine bulk materials into valve bags. The completely closed filling channel enables clean filling without any product leakage. The new dosing unit is maintenance free. Its optimised design and improved material selection mean no adjustments are necessary during wear-free service life.

The system offers increased performance that results from higher machine operational availability, from cost reductions though less cleaning and spare parts, and from higher profits through clean filling without material loss. The dosing device can also be retrofitted to old packers. Even without the SEAL technology, the ROTO-LOCK can offer advantages for customers.

The new VT filling module

In VT, the V stands for valve bag and the T stands for turbine. The specially designed valve bag filling spout is home to new technical components. The added development offers even more intelligent ventilation. The various ventilation points are automatically regulated and their air volume is matched to the respective product so that manual pressure adjustment is no longer necessary. The new VT filling module can be used modularly for the newly designed ROTO-PACKER, INTEGRA®, and ELEMENTRA® machine families. This enables customers who have several machines at their disposal to optimise maintenance work and minimise spare parts inventories onsite. The need for operator training is also significantly reduced. The new VT filling module can also be extended to SEAL technology, i.e. for ultrasonic valve welding. The filling spout is designed for easy maintenance. Changing the complete module is easy to do and all components are accessible. Systems that are equipped with the VT module can also be operated with a replacement module, while the single module undergoes maintenance under ideal conditions in the maintenance workshop.
