Precautions for operating a crawler-type shot blasting machine

When operating a tumble-belt shot blasting machine, first switch on the elevator. Once the elevator is running, start the shot blasting machine itself. Next, activate the abrasive feed system and the waste recovery/recycling unit. To shut down the machine, reverse this sequence of operations.

Before starting work, carefully read the manual and familiarize yourself with the specific characteristics of the tumble-belt shot blasting machine, as every unit has unique features. It is not advisable to operate the machine without a full understanding of its operation. Proper maintenance and lubrication are also crucial; regular servicing ensures peak performance and extends the machine's service life.

Heat treatment of wear-resistant components for tumble-belt shot blasting machines generally does not alter the shape or distribution of the graphite present in the material's initial state. In gray cast iron, the primary factor influencing performance is the stress concentration caused by flake graphite; consequently, the strengthening effect of heat treatment is far less significant than it is for steel or malleable cast iron. Heat treatment processes for cast iron primarily consist of annealing and normalizing. In malleable cast iron, the spherical shape of the graphite minimizes the disruptive effect on the matrix. Heat treatment allows the matrix to function optimally, resulting in a substantial improvement in the mechanical properties of the machine's wear-resistant components.
