Guyson's range of conveyorized blast machines includes flat belt systems like the Model TR-900, a reciprocating Model TRR-900 conveyor blast system for return-to-operator processing of components, the unique Model 700-B1 opposing V-belt conveyor system for high speed in-line blasting of small parts and roller conveyor machines like the Model RC-800 for in-line blast treatment of long sections of tube or bar material.
While some conveyor blast systems may be loaded and unloaded by hand, it is common for the automatic through-feed blast machines to interface with other in-plant material handling equipment and operate unmanned. Feed rates depend on the total surface area to be blasted and the number of blast guns, whether suction-blast or pressure-blast nozzles.
PLC control enables the use of electronic sensors to monitor key functions of the automated blasting system and alert an attendant before the continuous surface treatment process is compromised or interrupted. The blast guns can be automatically turned off when no components are present, to eliminate waste of energy and unnecessary wear-and-tear on the machine.

Guyson TR-900 Conveyor Blast System
Thru-belt conveyor models present components to a battery of pre-positioned
guns as the parts are transported through the blast cabinet on an
adjustable-speed rubber or honeycomb mesh conveyor belt, for a continuous
in-line processing system.
In Guyson TR-900 conveyor blast machines, the blast nozzles can be bracketed
in fixed position, they can oscillate or rotate on a turret to cover more
surface area, or linear traversing of nozzles can be synchronized with
indexed movement of the belt. Guyson's chambered design provides automatic
airwash of components and isolates the blast process for cleaner, quieter
operation.
Guide rails can be provided for alignment of components, or the belt can be
fitted with part-holding fixtures if components need to be held in a
specific orientation for processing. Guyson also offers an S-belt design
that allows multiple blast guns to be positioned below the work for
all-around blasting of long pieces.

Guyson TRR-900 Reciprocating Conveyor Blast System
Originally developed by Guyson for at-the-press deflashing of electronic components, the reciprocating conveyor machine concept has sparked new interest for single-piece-flow blast processing in work cell manufacturing.
In the Model TRR-900, components are conveyed from the load/unload station into the blast chamber, exposed to controlled blast from multiple nozzles, airwashed to remove residual media and dust, then transported back to the loading station. By a combination of indexed movement of the conveyor and synchronized nozzle motion, whether oscillating or programmed linear traversing of the blast guns, the automated blasting process is consistently precise and thorough.
Various configurations of the reciprocating conveyor are possible, according to the individual user's processing requirements.

Guyson Model 700-B1 Opposing V-Belt Conveyor Blast System
The special niche of the Model 700-B1 is high speed, continuous in-line
selective blast treatment of small precision components that must be
processed individually. Components are grasped and transported by twin
opposed urethane rubber V-belts, moving through blast from up to 16
pre-positioned blast guns. The blast cabinet is partitioned to isolate the
noise and dust of the blasting process and to create a separate chamber for
airwash blow-off.
The spacing of the conveyor V-belts is adjustable to accept different sized
components up to a width of 4 inches, and the belt speed can be adjusted to
allow for different processing rates for each component. High speed
automated loading of components into the 700-B1 is normally by a vibratory
bowl feeder.
Proven to be one of the fastest in-line conveyor blast systems for deburring
and deflashing work, the Model 700-B1 has been remarkably successful for
several other specialized surface treatment applications.
