Automatic Sandblasting Machine Workflow: (1) After the inner tank reaches the sandblasting workstation, the chamber door closes and the positioning mechanism (fixture) activates to secure the workpieces; (2) The rotation motor of inner tank drives the workpieces in a circular motion; (3) The moving motor of spray gun extends the spray gun into the workpieces to commence sandblasting; (4) The spray gun continues ascending until reaching the top of the workpiece, then begins descending; (5) Upon reaching the stop position, sandblasting ceases, the spray gun stops moving, and the positioning mechanism releases; (6) The chamber door opens, and the conveyor chain moves the inner tank forward to the unloading station to await removal.2. Automatic Shot Blasting Machine Workflow: (1) Workpieces pass through the automatic shot blasting machine continuously, and the shot medias are thrown out at high speed by the blast wheel to perform shot blasting treatment on the workpieces.3. Workpiece Conveying Process: (1) Workpieces awaiting processing → Loading conveyor chain → Chamber conveyor chain → Unloading conveyor chain → Semi-finished product unloading4. Sandblasting (Shot Blasting) Cycle Process: (1) High-efficiency shot blasting → Concentrated shot discharge into lower hopper → Horizontal and vertical screw conveyors → Elevator → Separator storage → Shot control valve → Shot guide pipe to shot blasting machine → High-efficiency shot blasting5. Ventilation and Dust Removal System: (1) Separator dust → Ductwork → Main duct → Cyclone assembly → Dust collector → Fan discharge (2) Shot blasting chamber dust → Main duct → Cyclone assembly → Dust collector → Fan dischargeProduct ComponentsWorkpiece Conveying System: Available in either an accumulation conveyor chain system or a standard continuous conveyor chain system, which can transport workpieces from the loading position to the sandblasting or shot blasting station. After shot blasting, it conveys the workpieces to subsequent processes or the unloading area.Sandblasting/Shot blasting Chamber: The main chamber is constructed with a rational frame structure of steel plates and profiles. The sandblasting machine is equipped with workpiece positioning aids and a workpiece rotation device. The shot blasting machine is equipped with a high-efficiency shot blasting unit.Sandblasting System: Consisting of the sandblasting machine, sandblasting hose, nozzle, etc., it is the primary equipment for performing sandblasting rust removal. Sandblasting machines are categorized into two main types based on operating principle: pressure-fed and suction-fed. Pressure-fed machines mix abrasive and compressed air thoroughly within the same pressure vessel before projection, maximizing compressed air utilization. Since both air flow and abrasive flow are easily adjustable to achieve an ideal mixing ratio, this method offers high efficiency, low energy consumption, and reduced abrasive usage, making it particularly suitable for large-area surface cleaning requirements.Shot Blasting System:Composed of multiple shot blasting generators. Shot media flows into the distributor wheel via gravity through the inlet pipe, undergoes pre-acceleration, and is ejected through the directional nozzle. The blades further accelerate the media, propelling it at high velocity to deliver powerful impacts on the workpieces, thereby achieving cleaning objectives.Shot Circulation System:This system comprises a vertical screw conveyor, horizontal screw conveyor system, bucket elevator, BE separator, shot storage hopper, pneumatic shot control valve, and shot guide pipes ect.Dust Collection System: Comprises a dust collector and fan ductwork. Dust collector structure: The pulse-jet dust collector consists of a housing, pulse-jet cleaning device, filter cartridges, ash hopper, and discharge device ect.Control System: The pneumatic control system incorporates air preparation components, pneumatic valves, and pneumatic actuators; the electrical control system employs PLC program control with intuitive touchscreen operation.Product FunctionsProduct Features: Achieves fully automated processing of workpieces, including automatic loading, sandblasting (removing rust, oil contamination, and oxide layers), shot blasting (enhancing surface hardness and roughness), media recovery, dust purification, and automatic unloading—all without manual intervention.Product FeaturesConveying System Features(1) Utilizes accumulation conveyors to determine optimal logistics conditions based on production requirements, enabling seamless integration of all factory processes into a unified system;(2) Conveyor units can halt, accumulate, or perform inclined accumulation without disrupting system operations, providing production flexibility to accommodate diverse operational demands;(3) Compatible with virtually any conveying equipment type, offering broad adaptability;(4) Enables regionalized storage for different work types, balancing production efficiency across various stages;(5) Installed overhead, the accumulation units can traverse inclines, curves, and vertical elevations, bypassing ground equipment pathways to significantly conserve floor space;(6) Ideal for computerized program control, ensuring orderly and high-efficiency production with scientific management capabilities.Features of the Sandblasting Section(1) When abrasive consumption reaches a certain level, the system automatically replenishes abrasive; when sufficient abrasive is added, it automatically stops replenishment.

Blades, deflector wheels, and directional sleeves are manufactured from specialized high-chromium wear-resistant materials, prolonging operational durability.(4) Blade replacement is simple and convenient. Blades are secured to the wheel by centrifugal force; removal requires only gentle reverse tapping.(5) A limit switch is installed on the shot blaster. When the top cover is opened for maintenance, the equipment cannot start, ensuring operator safety.(6) Adjusting the position of the locking limit gate achieves uniform shot thickness and flow rate.(7) The air separation zone height is 305mm, providing ample space for effective separation of shot and contaminants;(8) Broken shot is completely isolated, allowing only good, reusable shot to flow into the shot storage hopper.(9) Adapts to different workpieces.Features of the Dust Removal Section(1) A primary dust removal method is employed, achieving an efficiency exceeding 99.9%. Since dust particles do not penetrate deep into the filter media, this structure facilitates easy dislodgement during reverse-air cleaning. This results in high filtration efficiency and extended service life.(2) This dust collector employs pulse differential pressure reverse-blow cleaning. When the pressure differential across the filter cartridges reaches the preset value, the system automatically initiates pulse reverse-blowing until the differential pressure falls below the set point. Additional features include filter cartridge clogging alarms and manual forced reverse-blowing ect, making it particularly suitable for extended and high-volume operations.Easy Operation & Maintenance(1) Equipped with a graphical touchscreen interface, new operators can achieve independent operation after just 2 hours of training. Core components (sandblasting machines, separators etc.) feature modular design, with an average daily equipment failure rate ≤0.05%, minimizing downtime losses.Intelligent Monitoring(1) TIMS' automated, intelligent and information-driven sandblasting production line utilizes PLC and touchscreen systems to display and monitor real-time data including conveyor speed, various pressures, production capacity and safety parameters ect. Abnormal conditions (e.g., excessive pressure, insufficient coating) trigger audible and visual alarms while simultaneously recording maintenance cycles for core components (sandblasting guns, shot blasting machines).High Efficiency & Low Consumption(1) TIMS's automated, intelligent and information-driven sandblasting production line features fully automated process design to shorten design cycles.
