Surface International manufacturers continuous overhead conveyor shot blast machines which can be used for a wide spectrum of applications and work piece shapes and sizes. Characteristics
Applications
Applications include blast cleaning welded steel fabrications, deburring and homogeneous die-cast parts, and peening dynamically stressed components. Batches of small components or singular large, heavy work pieces can be treated. This flexibility is achieved by several special features : Rotation and oscillationTo achieve complete coverage, the work piece carrying hooks rotate and stop automatically at different location in the blast chamber. This rotation and oscillation process means that even highly complex work pieces, with hard to reach surfaces, can be safely and accurately treated. Hook and hoist optionsThe transport system can be designed for different size & weights. As an option, carrying hooks are available with integrated chain hoists for operational ease and safety. The ProcessThe work pieces are transported manually on rotating hooks or automatically on an overhead rail system into the blast cabinet. The blast cycle runs in accordance with the preset program and blast time. Used abrasive and fines fall through the abrasive collection hopper beneath the blast cabinet and are transported via a screw conveyor to a bucket elevator and to the abrasive reclamation unit. In the reclamation unit, the used abrasive is separated from fines and contaminants and returned to the abrasive silo. The screw conveyor to provide targeted cleansing/ separating of sand and heavy contaminants from the used abrasive. The conveyor should ideally be installed with a magnetic separator (also optional) to remove sand in order to prolong the service life of the machine. The abrasive then goes to the air wash separator as before. Manually Operated MonorailAs standard, the monorail system is designed in a single or Y-shape and equipped with two carrying hooks made from manganese steel. The work piece batches are manually pushed to the door of the shot blast machine where they are automatically taken by a feeding system. For especially heavy work pieces there is the option to install an automatic transport facility over the whole length of the overhead rail system. Lifting GearsDepending on the work pieces to be treated, and the preceding and subsequent processes, it may be advantageous to combine the carrying hooks with a chain hoist so that work piece batches or heavy parts can be easily picked up. The chain hoist is operated directly at the loading/unloading station of the overhead rail system. Blast Cabinet with wear resistant liningThe blast cabinet of this machine is completely lined from manganese steel. The advantage of manganese steel: it is hardened by the impact of round abrasive from 20 HRC to more than 50 HRC, so it has extremely good wear characteristics. Wear plates around the âhot spotâ provide additional protection for the cabinet. Made from 10 mm thick manganese steel, they overlap, suspended on a carrying system. To seal the cabinet, a slot seal is integrated in the machine roof to avoid the escape of abrasive from the monorail slot. The sealing system consists of a manganese steel labyrinth with a double rubber lip and additional strip brushes. Abrasive RemovalDuring the blast process, dust, broken abrasive and other solid particles or contaminants (fines) are generated by the rust and scale removed from the work pieces. The fines are separated in the abrasive reclamation unit which is individually adjustable to the different types and sizes of abrasive. The Abrasive reclamation unit consists of an impact separator and a cartridge filter. The cartridge filter provides the necessary negative pressure to remove dust. It is installed separately beside the shot blast machine.
Standard Tumblast machines are the flexible, low-cost solution to batch clean tumble-proof components in the most efficient and economical way. This machine has multiple applications such as :
Features
The tumbling action of the belt conveyor ensures that components are continually exposed to the blast stream and completely cleaned. For easy unloading, the belt conveyor is reversed, delivering the components into the loading skip or stillage. Optimized shot blast effectDuring shot blasting, the work pieces, regardless of size and shape, are evenly and continuously tumbled. This is necessary for the effective and uniform treatment of all surfaces.
Rotary Barrel Type Shot Blasting is Optimum shot blasting for small, flat and light components .It is probably the smallest batch cleaning machine in family of Airless Blasting machines. This is a smaller version of tum blast machine. The rotary shot blasting machine is provided with a control panel and electronic timer as standard supply. The machine is suitable for small job shops, foundries & forging units.
