METSO MINERALS RED BOOK Performance Data of Nordberg Crushing Equipment 0. Introduction Metso Minerals Red Book is meant to be used by marketing and service personnel of Metso Minerals, to help them to apply products and to estimate their performance and operation costs in use. The curves published in this file are mainly based on the tests carried out at Metso Minerals (Tampere) test plant and laboratory. The feed material in most of the tests has been clean, middle hard granite rock or gravel with different fractions. Tests have been carried out by crushers working in open circuit. In the crushing tests the feed fraction depends on the crusher. The maximum feed size has normally been near by maximum easily crushable feed size of the crusher. The lower limit of the feed fraction has been equal to close side setting (css) or lower. Only some of the secondary GCone crushers have been tested by zero-based material which is often used in usual crushing work.

C Jaw Setting Limits

VHL 9/26/2007 9:46 AM

This table contains up to date C Series jaw crusher setting limits. If some other document has different information, it is incorrect or old. Minimum close side settings (c.s.s. are valid for Metso Minerals (Tampere) Oy reference material (granite, Wi (Bond) = 15, Shatter = 30, LosA = 20, Crushability = 35) and these values are generally determined by a power limit. The settings are nominal values with new standard jaws. The closed side setting is meant to be shortest distance between the fixed and movable jaws by measuring the setting in accordance with the recommended method for each corresponding set. The maximum feed size is a maximum recommended material size (medium dimension), again also when the crusher is equipped with new jaws. Typically this value is about 80% of the feed opening depth.

GP Cone Setting Limits

This table contains original GP Cone setting limits. If some other document has different information, it is incorrect or old. Minimum close side settings are valid for Nordberg-Lokomo reference material (granite, Wi (Bond) = 15, Shatter = 30, LosA = 20) and the value is determined by the power or pressure limit, which gives higher minimum setting. Maximum close side setting is the nominal value for new liners, when the main shaft is in position 4mm upwards from the lowest position. Manufacturing tolerances cause variation to the maximum setting.

1. Rock Tests and Correlations This section contains knowledge about rock tests at Metso Minerals (Tampere) rock laboratory, characteristics of different rock materials, and some correlation curves between different rock test methods. Correlation between Flakiness Index (EN933-3) and 1:3 test method (Earlier DIN 52114, nowadays Shape Index EN 933-4) For this chart we have carried out 42 crushing tests with GP200S and HP300 crushers and measured products by both methods. From those tests we get total of 377 points to the chart. Rock Laboratory Some years ago we got some new testing equipment to the rock laboratory in Tampere. For the implementation we made large research project for 12 different rock materials. In the project we carried out all the rock tests, old and new, in our laboratory and some other tests in Technical Universities in Tampere and in Helsinki. Summary of the results is printed in a table and all the correlation charts are based on this table. Correlation Figures Due to long history of testing different rocks, it has been possible to create the correlation between most common rock test methods. This obviously gives us chance to make only those rock tests that are really required. There can be seen difference between Tampere and Milwaukee Abrasion Indexes. This results from the different steel paddles used in Tampere and Milwaukee laboratories. Also Bond Work Index is in different level if Tampere and Mâcon results are compared. Reason for this is unclear. Anyway, be sure that you read test result from right laboratory, when it is question of other tests than Crushability and Abrasiveness. Liner Lifetime In this book all the liner lifetimes are based on medium hard granite what has a lifetime factor of 1. When material to be crushed is tested in our laboratory the liner lifetime factor can be estimated from this chart. This chart does not give exact number because the abrasion index test is not real compressive crushing test. Please note that the figure has been changed quite a lot especially in high abrasive applications. This figure bases on real test data. SiO2 and Lokomo Ai If you know the SiO2 content of the rock you can estimate corresponding abrasion index with the help of this chart.

ABRASIVENESS AND CRUSHABILITY Main principle The purpose of test is to establish Abrasiveness and Crushability according to NF P18-579. The Abrasiveness gives an indication of the abrasiveness of the rock material. The Crushability value can be used for estimating how easily the tested material breaks down. The Abrasiveness Tester

TEST PADDLE

The paddle is clamped in the slot of the hub. A 500 g sample of material to be tested is placed in the drum. The paddle rotates for 5 minutes (4500rpm). After 5 minutes rotation the drum is emptied and the tested material is screened by 1,6 mm screen. Material which passes 1,6 mm screen is weighed. The test paddle is also cleaned and weighed.

LOS ANGELES TEST Main Principle The purpose of this test is to establish a Los Angeles value. Los Angeles value gives an indication of the resistance of material to abrasion and impact. Los Angeles test (in Nordberg-Lokomo) is based on ASTM -standard C131 - 89 “ Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles machine”. Los Angeles Machine The Los Angeles testing machine consists of a hollow steel cylinder closed at both ends having inside diameter of 711 mm and inside length of 510 mm. The machine rotates 30 (- 33) rpm for 500 revolutions.

Steel sphere Sample

On the interior surface of the cylinder there is a steel shelf plate (height 89 mm), which carries material and steel spheres until they are dropped to the opposite side of the drum.

To the drum with material is also placed 11 steel spheres which average diameter is 47 mm and each weight between 390 g - 445 g. Material Preparation The material to be tested:

9,52 mm - 12,7 mm 12,7 mm - 19 mm Total:

2500 g 2500 g 5000 g

Test Procedure The 5000 g test sample with the 11 steel spheres is placed into the Los Angeles machine. The machine rotates 500 revolutions (takes about 16 minutes). After prescribed number of revolutions the material is emptied from the drum and the tested material is screened on a 1,68 mm screen. Percentage of material passing through the screen is Los Angeles value. Result Calculation Los A - value

=

M -1,68mm / 5000 g * 100 [%]

FLAKINESS INDEX (IN TAMPERE) Main Principle The purpose of a Flakiness Index Test is to establish a Flakiness Index for whole sample or given fractions. Flakiness index announces percentage of flaky particles in the sample. Measurement of Flakiness Index in Tampere is based on EN –standard (EN 933-3). Table 1.

Test Procedure Dry sample is sieved for different fractions by using sieve series according to table 1.The material in each fraction is weighed. After weighing each fraction is screened by the bar screen, where distance between bars is also given in the table on the previous page. In each fraction the mass of flaky particles which pass through the bar screen is weighed. Result Calculation Flakiness index announces percentage of flaky particle in the whole sample or in the given fraction (as the percentage by weight). An example of calculation:
