Wire Mesh Belt Machines uses up and down blast from the wheels allowing the abrasive to hit all sides of the part. This is especially useful for hollow or odd shaped smaller parts.
Either a continuous belt can be used with an entrance and exit conveyor for automated operation or can be a table with an operator loading and unloading with continuous blasting.
Advantages include ability to blast hot parts as well as blasting where part on part tumbling is not conducive.
