The mechanical sandblasting room consists of the sandblasting main unit, sandblasting chamber, auger recovery system, sand material lifting system, storage bin, dust collector, and control system, etc. The difference between it and the pneumatic recovery sandblasting room lies in the sand material recovery process.

The mechanical sand recovery blasting room requires customers to excavate a trench of 2.5 to 4 meters on-site. Inside the trench, horizontal and vertical screw conveyors are installed for sand recovery. The sand is collected to the hoist by the conveyors, then elevated to the storage bin by the hoist. The sand is reused by being dropped into the blasting machine through the blasting machine control system. The mechanical sand recovery blasting room is also equipped with a dust removal system, which draws dust generated during the blasting process into a dust collector via an air intake pipe, filters it through a filter core, and releases it into the atmosphere.

The mechanical shot blasting room utilizes a high-pressure, open-top blasting machine. The blasting machine features an upper closure design, connecting to the storage bin at the top. The equipment is controlled via an electric control system, allowing workers to initiate the shot blasting process remotely with a remote control.

Mechanical sandblasting rooms are generally cost-effective, suitable for customers with modest sandblasting requirements and cost-saving needs.
