LT1213 CAN BE USED FOR CRUSHING NATURAL ROCK OR RECYCLING MATERIAL IMPACTOR ADVANTAGES HIGH REDUCTION RATIO EXCELLENT END PRODUCT SHAPE HIGH CAPACITY SAME UNIT CAN BE USED AS A PRIMARY AND AS A SECONDARY CRUSHER VARIOUS END PRODUCTS CAN BE CRUSHED WITH ONE CRUSHING STAGE RECYCLING (SEPARATE THE STEEL FROM THE END PRODUCT) FINE PRODUCT IMPACTOR DISADVANTAGES NOT ECONOMICAL TO CRUSH ABRASIVE MATERIALS CAN’T BE USED FOR CRUSHING VERY HARD MATERIALS

LT1213 - CRUSHING NATURAL ROCK FEED MATERIAL LIMITATIONS AVERAGE BOND WORK INDEX LESS THAN 16 MAXIMUM IMPACT WORK INDEX LESS THAN 23 INDICATIVE ABRASSION INDEX LIMITS FOR ECONOMICAL OPERATION 180 g/t, MANGANESE STEEL HAMMERS 230 g/t, MARTENSITIC STEEL HAMMERS 550 g/t, CHROMIUM CAST IRON HAMMERS TYPICAL ROCKS -LIMESTONES, DOLOMITIC LIMESTONE, GYPSUM,TALC,CHALK,MARBLES,MARL, SCHISTS,SLATES THREE SPEED RANGE 450, 520, 600

LT1213 - CRUSHING RECYCLING MATERIALS TYPICAL RECYCLING MATERIALS CONCRETE WITH AND WITHOUT REBARS MIXED DEMOLITION MATERIAL-CONCRETE, BRICKS,WOOD,STEEL… ASPHALT

PRE-SORTING OF THE FEED MATERIAL CRITICAL FOR SUCCESSFUL RECYCLING OPERATION BREAKING DOWN THE OVER SIZE OF THE FEED MATERIAL WILL INCREASE THE CAPACITY UNCRUSHABLE MATERIALS MUST BE PULLED OUT FROM FEED MATERIAL MAX. RE-BAR DIAMETER 19 mm AND LENGTH 1000 mm

SETTING - EFFECT TO PRODUCT CURVE ATTACHED PICTURE SHOWS THE EFFECT TO PRODUCT CURVE WHEN SETTING IS CHANGED FROM 100 mm TO 30 mm REDUCTION RADIO INCREASE POWER DRAW INCREASES FROM 149 kW TO 212 kW THE 90% POINT MOVES FROM 120 mm TO 65 mm 90 Feed curve

ROTOR SPEED - EFFECT TO PRODUCT CURVE ATTACHED PICTURE SHOWS THE EFFECT TO PRODUCT CURVE WHEN ROTOR SPEED IS CHANGED FROM 450 RPM TO 750 RPM POWER DRAW INCREASES FROM 84 kW TO 217 kW THE 90% POINT MOVES FROM 100 mm TO 50 mm AMOUNT OF -10 mm INCREASES FROM 30% TO 45% EFFECT OF ROTOR SPEED TO HAMMER LIFE EXAMPLE FROM FRENCH QUARRY -ABRASSIVITY INDEX 1300 g/t -SPEED DROPPED FROM 650 RPM TO 400 RPM -HAMMER LIFE INCREASED FROM 50 HOURS TO 250 HOURS 90 Feed curve

HAMMER CONFIGURATION 4 HAMMERS SLOTTED HAMMERS HEIGHT LIMIT FOR CHANGING HAMMERS 60 mm 4 HAMMERS SLOTTED HAMMERS

NUMBER OF HAMMERS EFFECTING ON PRODUCT CURVE 90% POINT IS 80 mm WITH FOUR OR TWO HAMMERS AMOUNT OF -50 mm DECREASES FROM 64% to 61% Hard rock Speed 450 rpm Setting 90 mm High capacity 90

QUALITIES OF HAMMERS MANGANESE STEEL The only quality enabling to crush without breakage Concrete 50 to 100 hours Demolition 40 to 200 hours Asphalt 40 to 150 hours MARTENSITIC STEEL With same risks of breakage according to the materials processed and reduction requested. Resists better to the wear than manganese Concrete 60 to 150 hours Demolition 48 to 300 hours Asphalt 48 to 225 hours CHROMIUM CAST IRON Good for the asphalt processing if there is not tramp iron. High risks of breakage in concrete and demolition but the financial balance can be positive if the customer is aware of such risks and accepts them. Concrete 150 to 400 hours Demolition 120 to 800 hours Asphalt 120 to 600 hours

FEED CAPACITY - EFFECT TO PRODUCT CURVE WHEN FEED CAPACITY IS INCREASED END PRODUCT CURVE WILL BE SLIGHLY COARSER WHEN FEED CAPACITY IS INCREASED FROM 50 TPH TO 250 TPH POWER DRAW IS INCREASED FROM 61 kW TO 214 kW

AUTOMATIC FEEDER CONTROL ADJUSTABLE FEED CONTROL ADJUSTABLE POWER LIMITS ENABLE TO STABILIZE THE MATERIAL FLOW TO FOLLOWING PROCESS Example 2 Example 3 Example 1
