INTRODUCTIONINTRODUCTION
The Model G Precision Grinder is utilized in your post-harvest processing of hemp and cannabis.
The Model G de-stems, grinds and sifts, it is the first machine of its kind that gives users
complete control of their finished product with perfect consistency. The G’s low RPM grinding
preserves trichomes and separates stems from material simultaneously.
The G is composed of two primary functions identified as grinding and sifting assemblies. Each
function has independent speed control and can be utilized in unison or individually. This allows
complete customization in the processing of your product. Both assemblies are fully customizable
with 3 interchangeable screens sizes, 1/8”, 5/32” and 3/16”. Functions can be manipulated
and adapted further by utilizing the semi-automatic angle control via electric actuator.
INPUT VARIABLES
Variable Effects Option #1 Option #2
Speed of
the blades
Machine
Torque
RPMs
Number of
stems in your
biomass
Throughput
per hour
The SLOWER the grinding equates
to higher torque and increased
stem removal. Slower RPMs allow
buds more time to align with the
face of the blade, keeping them
intact. HOWEVER, there would be
less throughput.
The FASTER the grinder rotates,
the less torque it has, and the more
often it will cease (keep in mind,
ceasing is not an issue as long as
the machine is not ceased up for an
extended period). The higher RPM
gives the buds less time to align with
the grinding blades and, in turn, will
break more stems, putting them into
the final product.

Percentage of

The smaller the perforated metal
holes, the smaller your final
product will be. The smaller holes
will also be more effective at
removing stems. However, you will
have less throughput.
The larger the perforated metal
holes, the larger your final product.
The larger holes will be less effective
at removing stems. However, you will
have a higher throughput
Humidity
level of
material
Number of
stems in your

Grind
consistency
INCREASING the humidity level
of your biomass will DECREASE
the number of stems in the final
output. This is because dry stems
snap and fall apart instead of
bending and staying intact.
DECREASING the humidity level will
INCREASE the number of stems in
the final output. If your material turns
into a paste, instead of being ground,
it is too wet.
Angle
of the
grinding
volume
relative to
machine
markings
Number of
stems in your
biomass
Throughput
per hour
INCREASING the angle of the
machine (going from 0 to 5,
for example) will DECREASE
the number of stems in your
final output. This is because the
material will be ground for a
smaller amount of time.
DECREASING the angle of the
machine (going from 5 to 0) will
INCREASE the amount of stems in
your final output. This is because the
material will be ground for a longer
period of time.

between the blade and frame assemblies.
4. Sifter Cart – Oscillating cart below the Grinding Medium used as a secondary filtering process.
5. Perforated Metal Inserts – Quickly replaceable for custom final product and easy cleanability.
6. Grinding Frame – Everything gets fixed to this frame for operation via four studs.
7. Secondary Emergency Stop – The machine comes with an emergency stop on both sides of the
cart to ensure the operator can immediately always halt operations.
8. Locking Castors –The cart is easily movable and quickly lockable via these wheels.
9. Control Box – Removable machine interface that the operator uses to control the machine.

MACHINE ACCESSIRIES AND GUARDS IDENTIFIERMACHINE ACCESSIRIES AND GUARDS IDENTIFIER
1. Pulley Guard – Provides protection from the spinning pulleys for the sifter mechanism’s spinning
pulleys.
2. Motor Guard – Provides protection against the hot motor and sections of the grinding mechanism.
3. Wire Guard – Provides protection against (and for) the actuator and shielded wires.
4. Stem Catch – Catches the rejected material from the grinding volume. Tabbed for quick removal
and reinstallation, so operation interruption is kept to a minimum.
5. Ramp – Catches the ground material falling from the sifter cart and funnels into a container.
6. Shelf – Variable slot heights allow for different sizes of containers to be placed closely under the
ramp.

CONTROL BOX INSTALLATION
8844.DRY.TRIM [e-mail] greenbroz.com
Do not plug this box into a power source until all cables
have been fully fixed to their respective plugs and
all assemblies and accessories are installed. Rotating
equipment and pinch points can cause serious injury.
1. The control box is a 25cm (10”) x 30cm (12”) x 15cm (6”) electrical box that is required
for the operation of the machine. The box is not designed to get wet, so it can be quickly
removed for cleaning. No hardware or tools are required.
a. As seen below, the cart of the grinder has a bracket on the left-hand side that is used
to hold the control box. Simply slide the bracket between the gap on the back of the
box. Be careful not to bend or pinch any of the cables.

2. The box will have three yellow communication lines and a black power cable. The yellow
connections vary based on the number of pins included on the connections.
a. The box has 4-pin, 5-pin, and 6-pin connectors that coincide with the three female
connections on the left side of the table. Each of the cables can only fit into its
corresponding connection. It is not possible to connect the box to the table
incorrectly.
b. Do not plug the machine into a power source until all three yellow cables have been
fixed to their respective plugs on the table.
SIFTING CART & SCREEN INSTALLATION & DETAILS
There are motorized components on this machine that can cause
severe injury. When installing or removing ANY components or
assemblies, ensure that the machine has an active emergency stop
and is unplugged from any power source.
The Sifting Cart is held in a roller track on the Grinding Frame and fixed to the Crank Arm in
the Mechanical Housing via the short ¼” quick release pin provided for toolless installation.
