(6)

 Developing A Plant Layout

 What AggFlow Is & What AggFlow Is Not: How To Use This Tool  Benchmark

 Extremely Sophisticated Calculation Tool (Aggregate  :  Water)  AggFlow is not artificial intelligence – It does not think for itself

 What You Need to Start Using AggFlow:  Initial feed gradation

This is hard to measure given the sizes are typically larger than 8 inches. The most important factor in the feed gradation is the value passing the first screening point. For example, if the feed is going to a grizzly feeder with a 5 inch bar opening, then you want an accurate value for the 5 inch percent passing value.

Example #2: See: Feed Source Secondary Surge Pile Gradation.pdf  Major equipment in the plant

Note: AggFlow plant flow calculations can be performed with or without modeling the conveyors.  Crusher makes, models and settings

 Screen sizes and mesh openings

 Overall flow of material through the equipment in the plant

 AggFlow Menu Definitions

File Edit View Run Database Selected Object Summary Modes Windows Help

 Setting User Preferences

User Units Washing Screen Area Display Titles Lines-Grid Tolerance Display Size Ranges Saving The Plant HTTP Setup Update

 Create a Plant From The Hand Drawn Flow Sheet Example #3: See: Rough Sketch.pdf

(7)

 Developing A Plant Layout (continued)

 Equipment Placement & Layout

 Effect of initial feed on plant accuracy  Equipment descriptions - top level

 Flow Stream Layouts  Initial connections  Adjusting bend points  Orthogonal lines

 Add Monitors To See Results

 “Run” The Plant

 User Interface  Zoom features

 Graphical Undo

 Plant Configuration Advisor – How to use it

 AggFlow Tricks

 Multiple windows can be open at once  Read the bottom panel for information!  Always keep your program updated  Use your best resource – Open the manual!

(8)

 Crushers

 Crusher Database Assumptions

 Model Selection  Manufacturer limits  Book gradations

 Interpolation of Gradations

 Reduction Ratio Monitoring

 Calculation Method

 You are in complete control of the output gradations. AggFlow does not calculate automatically.  AggFlow does not calculate an output gradation based on changes to input gradations

 You must specify the output gradation by adjusting the equipment set-up in the program  AggFlow actually ignores the input gradation and relies completely on your output specifications  AggFlow does pay attention to the incoming flow rate and ensures mass balance

 Some Impact Crushers Track Input Size Range

 Sample of Making Larger Rocks Out of Smaller Rocks  Put sand and gravel into a jaw

Example #4: Sand to Jaw Example #5: Bad HSI

(9)

 Crushers (continued)

 Common Mistakes  Modeling mistakes

 Using Screen Efficiency To Model Different Mesh Openings  Using the screen efficiency override method

(11)

 Screens (continued)

 Missing from VSMA

 Non-wire deck area requirements  Open area adjustment

 Varies from one manufacturer to the next  Multi-openings same deck

 Non standard screens  Pep screens

 Banana screens

 Refer final design to manufacturer

 Common Mistakes  Modeling mistakes  Not sized correctly

 Equipment not set-up correctly

 Other constraints; conveyors, chutes and feeders  Misapplication of equipment

 Operational Mistakes

 Equipment is not maintained  Screen is not fed correctly  Screen operating parameters  Wrong media

 Wrong flow direction  Water amounts

 No correction for screen operational parameters  Under loaded screens

(12)

 Running The Plant

 Red Flags

Note: AggFlow highlights problem areas and equipment exceeding warning levels by turning the equipment in the worksheet red. However, the program will continue to perform calculations as if there was no problem. Therefore, you can choose to address, or ignore, red flags at anytime.

 Warning Levels

 Three warning levels:

 Alarms; AggFlow alerts you when calculated results may not match field results  Warnings; Items to be aware of, will not likely affect calculations or results

 Missing Limits; Manufacturers have not supplied crusher limits and AggFlow has no limits here Example #7: Warning Levels

 Maximize Plant Production Feature

 Fine-Tuning Your Calculations & Plant Designs

 Why Do So Many Operations Continue Along With Known Bottlenecks?

 Calculation Levels  Level 1

 Setup with generic data

 If you have average material with standard compression crushers this gets you to level 2  If you have impact crushers you may or may not get to level 2

 Data varies greatly from one manufacturer to the next  You may need crusher samples to get past this point

 Results may be off - but experts report that incremental change is usually very good

 Level 2

 Take plant measurements to verify results  May identify problems

 Experienced aggregate manager uses this model to identify improvements and problems

 Level 3

 You have enough data to totally optimize production with accurate results

 You reach a point where "what if" calculations are consistently accurate and reliable. Use your experience to estimate where that point is.
