Sand vacuum suction machine Vacuum Recovery System VR vacuum sand Description: conventional abrasives both labor-intensive and time-consuming recovery methods, and vacuum sand is one of the most efficient, most economical and most effective cleaning method. This device is designed with a small structure, easy operation, easy maintenance, high efficiency and other characteristics, can be high-quality, fully complete the task. Vacuum sand blasting main function is the process of recovering their savings in the cabin, ground oil tanks or dry abrasive, and for cleaning the hull sections and complex parts of the abrasive. Vacuum sand pneumatic conveying system design is based, namely the use of high-speed air flow through the wear of abrasive sand suction tube into the reservoir from the workplace transport sand bucket, easy recovery, this system has the following characteristics: the system The cleaning method, compared with higher productivity. Since no mechanical moving abrasive recovery line, so reducing failure. Already treated surface painting process can be timely access. Because during operation without moving vacuum sand, while the unit easy to move and maintain.
