Sand Equivalent Shaker

Introduction

The motorized sand equivalent shaker features two separate electronic
timers (one preset at 45 seconds and the other preset at 10 minutes) to
increase accuracy and ease of operation compared to a spring-type timer.
It is recommended for samples in the laboratory.

The consistent, repeatable oscillation of the apparatus eliminates operator­caused variations.

The equipment meets specifications for the following tests:

ASTM D2419
AASHTO T176
California Test Method 217

Initial Installation
Remove the packing list and verify that parts have been received. Remove the
wood support packaging from underneath the motor. The unit is complete

assembled and ready for use. Place the machine where it is to be used in
the laboratory or field and mount it securely to a firm and level base. Plug or
connect to the electric power indicated.

Operation

Control Panel:

The controls are situated on the front, right hand side of the machine base.

Preset Travel and Speed:

The shaker has a throw of 8 ± 0.04” and operates at 175 ± 2 cycles per
minute.

Method:

Prepare the sample to be tested according to the governing agency
standard(s). Place the clear plastic cylinder containing the test sample and
rubber stopper in position on the slide assembly of the shaker. The end with
the spring loaded holder fits over the cork (rubber stopper) in the open end
of the clear cylinder.

Select the time period appropriate for the test, either 45 seconds or 10
minutes using the center toggle switch. Then press the start push-button
switch to begin the test. The test will end at the end of the elapsed time
selected, or by the operator pressing the pushbutton stop switch any time
during the test.

Maintenance

First unplug the machine from its power receptacle or source. Normal routine
maintenance consists of lubrication at several key locations. In addition, worn
components should be suspected if there is any unusual sound or action of the
machine.

Lubricate as follows:

A. The slide assembly should be lubricated once a month with

approximately three (3) drops of household oil on each end of the main
slide bar.

B. Two (2) grease fittings should be greased once a year with automotive
type grease. These are accessible from under the machine through the
fly-wheel.

C. The cam action guide, H-4374.18 and the two outside slide bars,
H-4374.27 can be greased by smearing a film of grease on each one.

siphon assembly, weighted foot assembly, wide mouth funnel, 3 oz. measuring
