The WashBox System is a secondary belt cleaning device and as such should be located onthe return side of the belt after the belt leaves contact with the head pulley. Preferably it shouldbe located before and after a set of return idlers to help steady the belt, in order to dampensystem vibration. This will ensure smooth and direct belt contact on the Razor-Back BladeTips. Direction of belt travel shown below, See Figure 8.BELTRUBBERSPLASH GUARDURETHANEWIPEFigure 8. Belt Travel Through WashBoxThe Hangers (17) of the WashBox mount to the frame / structure of the conveyor system. TheHangers have multiple height adjustment holes. The top inside edge of the WashBox shouldbe 0 – 1” from bottom of the belt. See Figure 9. In most applications it will be necessary toremove the Hold Down Roller for installation of the WashBox. Once the WashBox has beeninstalled in the correct location, the Hold Down Roller can be reinstalled.0 -1/2”Figure 9.

INTERAL CLEANER ADJUSTMENTSFigure 10. Razor-Back with Spray Bar AdjustmentRazor-Back with Spray Bar:Loosen Hex Head Bolt (50) on both tensioners, this will allow for height adjustment ofRazor-Back.Adjust height by tightening the Height Adjustment Bolt (52). It may be necessary to movethe Height Adjustment Angle (48).Once belt contact has been made, turn the Adjustment Bolt (52) until the blade tip hasmoved up a maximum of 1/8”.Make sure Spray Tube is angled 5-10 degrees into the belt travel. Tighten the tube clamplock bolts (50, 51).Now test run the conveyor. If chatter occurs, loosen the tube clamp bolts and rotate theblade tip about 5 degrees in the direction of the belt travel (Razorback only).If cleaning performance is unsatisfactory, slightly increase the force against the belt and testit again. If the cleaner has about 1/8” or more of material to remove, a primary cleaner maybe needed.Hold Down Roll:Lower or raise the Hold Down Roll so as there is 0 – ½” clearance between the bottom ofthe roll and the top of the conveyor belt. Adjustment of the Razor-Back will take up the gap.Urethane Wipe:Raise the Urethane Wipe by loosening the four-Arm Knobs (23) and raising the Wipe Holder(13) so the urethane is touching the belt. Then tighten the 4-Arm Knobs to lock theUrethane Wipe in place.Rubber Splash GuardRaise the Rubber Splash Guard by loosening the four-Arm Knobs (23) and raising the WipeHolder (13) so the rubber is one inch from the belt. Then tighten the 4-Arm Knobs to lockthe Rubber Wipe in place. This is installed to minimize water from exiting the front of theWashbox.ASGCO Mfg., Inc. - 13 - WashBox SecondaryBelt Cleaning System

MAINTENANCEAfter one day of operation: Inspect the cleaner for proper belt cleaning and operation.Weekly:Frequent inspection is the key to proper belt cleaning and easy secondary servicing.Weekly inspections are recommended, but actual service frequency may vary widelydepending on various plant operating conditionsHose down inside of the Wash box three to four times a week.o Including any build up on the Razorback blade tips front and back and rubbercushions front and back.Inspect each spray nozzleo To verify that no debris is clogging the tips of the nozzles.Run water through nozzles to verify the water flow.Adjust urethane squeegee to assure proper contact on the belt.Remove any debris build up at urethane squeegee on the outside of the wash boxConveyor belt needs to be centered entering the wash box.MonthlyEvery 3-4 weeks both Razorback systems need to be adjusted to ensure proper bladecleaning. Below are the steps to adjusting the Razorback Cleaners.Loosen the two horizontal bolts that are attached to the L bracket.Loosen the jam nut on vertical jack bolt.Rotate the jack bolt 1 revolution.Re-tighten the jam nut. Tighten the two horizontal bolts that are attached to the L bracket.ASGCO Mfg., Inc. - 14 - WashBox SecondaryBelt Cleaning System

TROUBLE SHOOTINGPROBLEMExcess vibration of scraper.SOLUTIONMake certain all bolts are tight.If belt is non-reversing, rotate the blade 5degrees in the direction of belt movement.Check for proper Scraper contact. Putadditional force on cleaner.Excess CarrybackExcess belt movement, cupping.Unable to tension scraper properly,belt moves away from blades.Frozen material on scraper.Poor Pressure from Spray NozzlesCheck for wear on cleaning tips.Check thickness of carryback. If the cleanermust remove more than 1/8 inch of material,then an additional cleaner maybe needed.Install a hold down roller to stabilize the beltsurface.Install a hold down roller to reduce sag ofthe belt when tensioning.Place heaters near scraper to melt frozenmaterial. (Use Caution not to burn belt orcleaner)Check to see if Nozzles are plugged. Checkto see if Nozzle filters need to be replaced.ASGCO Mfg., Inc. - 15 - WashBox SecondaryBelt Cleaning System
