Tex-116-E, Ball Mill Method for Determining the Disintegration of Flexible Base Material Overview Effective: August 1999 May 2000 This method determines the resistance of aggregate in flexible base material to disintegration in the presence of water. The test provides a measure of the ability of the material to withstand degradation in the
The test provides a measure of the ability of the material to withstand degradation in the road base and detects soft aggregate that is subject to weathering. The result of this test is the Wet Ball Mill (WBM) value. 1.2 The values given in parentheses (if provided) are not standard and may not be exact mathematical conversions.
The result of this test is known as the Wet Ball Mill WBM value Apparatus The following apparatus is required ♦ wet ball mill machine consisting of a watertight steel cylinder closed at one end with inside dimensions of 2588 ± 3 mm 10188 ± 18 in in diameter and 2731 ±
The wet ball mill can be divided into three types according to the motion characteristics: a simple swing type wet ball mill, a complex swing type wet ball mill, and a hybrid swing type wet ball mill. Applicable materials 1. Dry type The dry grinding is suitable for materials that can react with water, which may not be used for wet grinding such as cement, marble and other building materials

The Rainhart Aggregate Wet Ball Mill is used to determine the resistance of aggregate in flexible base materials to disintegration in the presence of water. These results are essential in determining whether the base will resist crushing, degradation, disintegration, and premature structural failure. Simply place a sample in the rotating bucket with six steel charges. The bucket will rotate 600 times at a

The dm test has been based on the apparatus used for the Texas ball mill test. The test method involved the testing of four representative subsamples of about 3.5 kg each. Performance related results have shown that if the durability mill index (DMI) based on the product of the maximum plasticity index and the maximum p245 remains below 100, good performance can be expected under most conditions. If the
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of ferrous and non-ferrous metals. The ball mill can grind ores and other materials either wet or dry. There are two kinds of ball mill, grate type and
Rainhart designs, manufactures, and distributes laboratory testing equipment for soil, concrete, and asphalt, located in Austin Texas we specialize in laboratory equipment and supplies for materials testing industry and has been in operation for over 70 years.
The durability mill (dm) test is outlined for use in specifications so that the degradation potential of a material may be assessed. The dm test has been based on the apparatus used for the Texas ball mill test. The test method involved the testing of four representative subsamples of about 3.5 kg each.

07/03/2006· We have a client requesting a wet ball value (TXDOT TEST METHODS 116-E) or, as an alternative, an LA Abrasion Test. The problem is they don't have enough material to run either test. Are there any other tests out there that would yield similar information with a smaller sample size (6000 grams or less)? Thanks in advance for any help. RE: Wet Ball Value or L.A. Abrasion Testing
22/05/2014· Ball mill is used to grinding ores or other materials after crusher, it is the mechanical equipment for getting finer particle products.
Jar Mills are used for wet or dry grinding, mixing and diameter and is configured to keep jars centered during operation. Welded steel frames, roller chain drives, and sealed ball bearings assure long service life. Mills operate on 115V, 50/60Hz, or 230V/50Hz electrical supply. Grinding Jars and Grinding Media are required for use with this equipment and are ordered separately. Jar Mill, 1
3.4 The total wet mixing time of a castable influences the rheological and final properties and therefore should be monitored. 3.5 This test method can be performed in a laboratory or on a stone site. 1. Scope. 1.1 This test method covers the procedures for determining the consistency of a castable using the ball-in-hand test. The amount of water used in a castable has a significant influence on
Grate discharge Wet Overflow discharge Wet Figure 8.5 Effect of mill filling on power draft for ball mills. The data is taken from Rexnord Process Machinery Reference Manual, Rexnord Process Machinery Division, Milwaukee, 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8.4 The speed of rotation of the mill influences the power draft through
