Catenary Hanger Pass Through Shot Blasting Machine for Small and Middle Castings

Sandblasting safety measures require that workers wear protective helmets, clothing, gloves, safety footwear, earplugs, safety goggles and other OSHA-recommended equipment. Provide workers with proper respiratory equipment. Respiratory protection is absolutely critical for sandblasting processes.

A typical 'capacitive discharge' blasting machine works by charging a capacitor from a battery, then discharging the capacitor through an external circuit, called the firing line, to fire the blasting cap.

Blasters are tasked with determining the size, or magnitude, of the explosive used and what type of explosive will work best. Other factors considered during the design phase include determining the depth, diameter and number of holes that need to be drilled as well as the spacing.

The Danger Zone should extend beyond the expected spread of the blast with a significant margin of safety included. The extent of the danger zone should be shown on a plan of the quarry and included in the Blast Specification. The danger zone may extend outside of the quarry boundary.

Hence, though Indian Regulations Prescribe 500 Meters as the safety distance for Blasting, Regulation 164 of Metaliferrous Mines Regulations of Government of India, allows blasting with certain conditions within the safety distance.
