Rapid Soil Processor

Introduction

Compact all-metal soil processor allows customer to produce five-point
moisture density relationship test results in about 5 hours. Processor also
handles samples for rapid compaction of a family of curves test. Processes

up to 30 lbs. of lean-to-fat and tough clays at field moisture in fewer than
15 minutes. Automatically separates and retains up to 3/4" rocks from soil to
prolong screen life. Processes soil to pass a No. 4 screen. Offset rotating drum
is motor driven; pre-set adjustments aren’t necessary. Automatic operation
frees up technician’s time. Order easy-to-install replacement screen separately.
Replacement parts are available. Overall dimensions: 32 x 36 x 53" (813 x 915 x
1346mm). Shipping wt. 408 lbs. (184kg)

Operation
The Rapid Soil Processor was designed and constructed to process Field
Sample Moist Soil Only. After the material has been processed, it can be rerun

regardless of moisture content; this is beneficial to reduce drying time or pro­duce smaller particles to absorb moisture. This machine can be used to blend
various types of soil regardless of moisture content but attempting to process
dry chunks could damage the screen and the machine.

DO NOT ATTEMPT TO TEST LARGER THAN 3/4 INCH AGGREGATE.

The Rapid Soil Processor is designed to process moist soils containing aggre­gates up to 3/4 inch diameter maximum. The machine is constructed to accom­modate 14-gauge screens. This is determined by the type of material and the
amount of gravel in the material to be processed.

Safety

1. CAUTION: The machine has 2,325 ft. lbs. of torque on the drum shaft.

2. The Guard over the drum gear and chain should be in a closed position

when the machine is in operation. It is easily raised for cleaning and loading
the machine.

3. The machine is equipped with three switches. Switch #1 on the arm of the

pressure plate automatically shuts the switch off before pressure damages
the screen or drum. Switch #2 is manually operated to control the machine
at any time and position. Switch 3 on the safety guard must be closed for
the processor to operate.

4. DRY MATERIAL OR MATERIAL CONTAINING AGGREGATE OVER 3/4

INCH SHOULD NOT BE PROCESSED.

5. The Spring Tension on the Pressure Plate, which releases gravel without

damaging the screen is Pre-Set and should not be changed.

6. The Weight on the Pressure Plate Arm has been pre-determined and should

be sufficient to move material into the screen.

Operating Instructions

1. Be sure that the Automatic Kill Switch (H-4215.50) is properly set

before starting the machine.

2. Detach weight from the Pressure Plate Arm (H-4215.3.4).

3. Release Catch (H-4215.3.12) on the Pressure Plate Guide and open the

material container space.

4. Be sure the Guard, (H-4215.9), is in place.

5. Both Switches (H-4215.50.1), must be correctly set to start the test.

The yellow guard switch has to be closed and the pressure plate switch
has to be open.

6. Fill the machine with material to be processed. When full, attach the
weight to the pressure plate arm.

7. On some impervious materials, the cut face of the material will appear
glazed slowing the cutting process. Stop the machine and break up the
material. Resume operation.

8. If gravel accumulates on the face of the material, stop the machine,
open the pressure plate, and remove the rock.

Maintenance

1. The Pillow Block Bearings on the drum should be greased
once every six months. Be careful not to blow the grease seals on
the bearings.

2. Do not oil the chain drive. Check periodically for slack in the chain-keep
the chain tight.

3. Check oil level in the gear box every six months.

4. All Bearings are stock items in most localities and can be replaced with
a minimum of down time.

5. To change the screen see the ”Screen Replacement Procedure“.

6. Pre-shaped Screens (H-4215.32) may be ordered from Humboldt.

Unit Cleaning

1. Release Pressure Plate (H-4215.3 and H-4215.3.12), and bring to open
position; by lifting out the Pressure Plate (H-4215.3.4), the machine will
open, exposing the inside of the Pressure Plate, Plate Guide, Screen

and Table Top.

2. The Cleaning Attachment on the back side, will help clean the Screen
by letting the machine run a short time while it is empty.

3. Tools used in cleaning the machine are a Wire Brush, Rubber Mallet,
Bristle Brush, Spatula and Knife.

4. If the machine is not used constantly, let the material dry on the screen.
Then start the machine and tap the screen with the rubber mallet.

5. Wipe all parts which come in contact with the processed material, with
a damp cloth containing light oil. This will prevent the material from
sticking but will not affect the test results.

Accessory Parts for Screen Replacement
