KNNJOO dreservation line shot blasting machine means steel surface before machining shot blasting and coated with a protective primer processing technology. After pretreatment of steel products to improve the mechanical and corrosion resistance of the metal member, to improve the fatigue resistance of the steel sheet, extending its life; and to optimize the production process of steel surface state, in favor of CNC cutting machine cutting and precision blanking. Furthermore, since the steel before processing shape comparison rules, in favor of mechanical descaling and automated paint, so the use of steel pretreatment can greatly improve the efficiency of clean-up operations, reduce labor intensity and pollution clean-up operations on the environment. Steel plate pretreatment line shot blasting machine sliding on the main discharge, the discharge roller, preheating, nine parts consisting of shot blasting, painting, drying, automatic monitoring systems, efficient dust collector, electric control. The entire production line by Siemens PLC programmable control, using a shift register and the photo detector, automatic measurement of plate thickness and width automatically adjust the lift height and width projectile cleaning device.

Range：It can be widely used 0.5-6.5 meters width steel, the steel surface rust, paint, bridges, offshore oil drilling platforms, port facilities, containers, boilers, metallurgical and other manufacturing industries.

Typically includes the following main parts：
- Access to materials roller conveyor (cross conveyor can also be configured to increase efficiency)
- Pre-heating or heating and drying equipment (so that subsequent paint dry faster)
- Roller conveyor shot blasting machine (it can handle sheet width range of 0.5 - 5m, the processing speed of 1.0 per minute - 10m)
- Just cleaned steel surface via a spray booth spray a layer of water-soluble or solvent-based primer to form a temporary corrosion protection layer.
- Drying channel through the plate conveyor to transfer material to a new paint outlet passage
Joint straight fire, before the furnace hot air circulation, automatic width detection and throwing the first adjustment, special function H900 polishing head, ETA system, and clean-up detection systems Darlington nine pretreatment line to become the industry's choice.
