Shot Blasting Test Steps for Crawler-Type Shot Blasting Machines
Share to:
When a small shot blasting machine starts operation, the workpiece is placed into the rubber crawler drum. The operator closes the equipment door and starts the machine. The shot blasting cleaning machine activates the crawler to run forward, and the workpiece rolls continuously. The shot blasting machine projects steel shots at high speed onto the surface of the rolling workpiece, enabling effective and uniform cleaning of the workpiece.

Steel shots flow into the screw conveyor through the sliding holes on the crawler, then are conveyed to the bucket elevator. They are lifted to the BE separator by the bucket elevator, where the separator stores them for later use. After shot blasting, the door of the shot blasting chamber of the crawler-type shot blasting machine slowly opens, and the crawler reverse button is activated to unload the workpiece.

Features: The small shot blasting machine adopts a cantilever centrifugal shot blaster, which has a long service life and a simple structure. The BE separator is selected for its good separation effect, high productivity, and benefits to rotating blades.

A pulse filter cartridge dust collector is used, with a dust emission concentration lower than the specified standard, greatly improving the working environment for shot blasting workers. The selection of wear-resistant rubber crawlers reduces collisions and damage to workpieces and lowers machine noise. The projectile coverage is uniform, reducing shot blasting dead angles. Wear parts have a long service life, and replacement and maintenance are convenient. The equipment operates with low noise.

The electrical system is controlled by thermal relays (or PLC) and a control cabinet. The small crawler-type shot blasting machine with an acousto-optic alarm device is suitable for various workpieces, including rust removal or shot blasting strengthening of workpieces in small, medium, and large batch production. The cleaned workpieces must be castings and heat-treated parts weighing less than 150 kg that can withstand impact. The crawler-type shot blasting machine can be used independently or in a production line and belongs to the category of large casting machinery.
