PHOENIX/KISA Logwasher

The PHOENIX/KISA Twin Shaft Logwasher is an essential component of a wash plant’s aggregate washing equipment. The Logwasher removes dirt, loam, clay contaminants, and other deleterious materials from raw aggregate materials such as dirty limestone, dolomite, and high silica content gravel. Logwashers have the capabilities of handling large rock and high tonnage feed capacities from 220 – 660 STPH. The rugged drives, shafts, and paddles are ideal for a variety of applications requiring severe scrubbing and de-agglomeration.

Impressively, these Logwashers can process up to 660 Tons Per Hour with rocks up to 12” and provide low water consumption as low as 1.0 GPM per ton of feed. Furthermore, optional upflow nozzles can be added to enhance wood/organic removal.

FEATURES & BENEFITS

• 12” Nominal Clearance allows for crushed, angular material to pass through the trough.
• Paddles are made from Hardox^™ 500 to provide extra durability against the toughest feed.
• Trough is made from thick steel rolled to a “U” cross-section to enhance the mixing-in of low-density material (wood, organics massive clay balls)

APPLICATIONS

• Aggregate & Gravel Washing
• Coal & Wood Removal from Coarse Aggregate
• Scrubbing Coarse Lateritic Ores
• Cleaning Crushed Dirty Limestone/ Dolomite for Chemical & Cement Industries

THE PROCESS

Material is fed to the lower end of the trough.

Water is added by spray-bar arrays at the top end of the trough, while solid material advances up the inclined trough by paddle action.

Force-synchronized, interlocked counterrotating twin shafts with staggered paddles create intense paddle-rock & rock-on-rock shear action to remove the impurities from the material.

Scrubbed material dumps from the discharge chute at the top end of the trough and waste liberated fines & low density suspended matter exit through the discharge launders.

Here are before and after pictures of extremely muddy material shown at the intake of the PHOENIX / KISA – doubleshaft log washer and the clean material at the output. Impurities have been cleaned away.
