How to choose

For abrasion, the Los Angeles Abrasion Testing Machine turns its drum at 30-33 R.P.M. and the Digital Los Angles Abrasion Testing Machine adds an automatic counter, while the Devel Attrition Tester uses two hollow cylinders at 30-33 RPM and the Dorry Abrasion Testing Machine a disc at 28-30 RPM.
For particle shape, the Flakiness Sieve Set and Thickness Gauge class particles from 6.3 to 63 mm as flaky when thickness is less than 0.6 of their size, and the Grid Sieves offer slot widths from 2.50 to 50.0 mm for hand sieving.
For strength values, the Aggregate Impact Tester drops a 13.75 +/-0.25kg hammer through 380 +/- 5mm with a blow counter, and the Aggregate Crushing Value Apparatus uses a 150mm dia. cylinder and 148mm plunger under a gradually applied load.
For splitting samples, the Sample Splitter has 12 mm chute bars giving openings up to 108 mm and a 30 litres hopper, while the Riffle Sample Divider comes in sizes from 7 mm to 75 mm.
For surface friction, the Skid Resistance And Friction Tester works on site and in the laboratory with 6 rubber sliders, and the Accelerated Polishing Machine holds 14 specimens on a road wheel running at 320 ± 5 rev/min.

Frequently asked questions

What does the Alkali Aggregate Reaction Bath hold?

A stainless steel chamber holds 36 specimens of 25 x 25 x 285 mm in NaOH (Sodium Hydroxide) or another solution. The temperature can be set from ambient to 80°C with a digital controller to 2°C accuracy.

What is in the Sand Equivalent Test Set?

Four measuring cylinders, two rubber stoppers, a measuring can, irrigator tube, siphon assembly with bottle, weighted foot, funnel, graduated rule and 1 liter of stock solution, with a 500x400x130 mm plastic carrying case.

Which jaw crusher sizes are listed?

Sizes run from 100x150mm with a 3 H.P. motor and 150-200Kg/hr capacity up to 375x600mm with a 15 H.P. motor and 1 Ton/hr, all on a 440 V three phase supply with manganese steel jaws.
