4Machine use, technical specifications and description.
4.1 Machine use.
The crusher is designed for grinding raw materials such as cereals (wheat, rye,
barley, oats), maize, legumes, cake meals and granulated dry forage, namely for feeding
purposes.
The to-be-processed raw material is filled through a feeder to the milling chamber
in which a rotor is installed with shaft-suspended cutting knives. There it is thrown at
high circumferential speed against the chamber periphery formed by a sieve. Bumps
between the sieve and the cutting knive blades crush the material which falls into the
outlet hole. Grain size of the ground material is given by sieve perforation.
The crusher is powered by driving unit Models PJGCV160 and PJGCV190.
4.2 Technical description.
Basic structure of the machine consists of a frame that is welded of tubes and
provided with tube supports. Pins for plastic wheels are welded on two supports. A
metal plate is welded to the frame, onto which a crusher drive is bolted for the
installation of the driving unit. A hopper, welded of sheet steel, is slid from the side. The
sieve is bolted under the drive.

5Instructions for use
5.1 Assembling the machine
The crusher is delivered in a cardboard box with the dismounted hopper, two sieves
with hole size of 3 mm and 5 mm. The hopper is to be mounted onto the corpus neck.
5.2 Installing the driving unit onto the crusher
Driving unit represents a power source for the machine and is to be installed into a
flange formed in the upper part of the crusher drive. On the bottom side of the complete
flange there is a cylindrical part that is to be inserted into the flange in the crusher drive when
putting the driving unit onto the crusher. The second part for seating the driving unit onto the
gearbox case is a pin located on the upper surface of the crusher drive flange, which is to fall
into the hole in the driving unit flange in order to arrest the position of the driving unit on the
crusher.
5.3 Procedure of driving unit installation
Installing or removing the driving unit, you are advised to approach the machine from
the side of air filter and carburettor control on the engine of the driving unit.
* Be careful when installing or removing the driving unit or when transporting it to another
machine. The exhaust silencer is hot when in operation.
1. Put the crusher on a firm base. Clean all connecting points for the driving unit and the
inside of the clutch disc.
2. Clutch disc in the crusher drive must not be greasy as a slippage of the centrifugal clutch
might occur that could result in a damage to the clutch lining and to the engine crankshaft
sealing due to high temperature.
3. Grip the driving unit with one of your hands at a holder which is situated on the lower part
of the driving unit flange and with the other hand at an upper joint of the handrail of guiding
handles.
4. Slide the driving unit onto the crusher so that the cylindrical part of the flange completely
falls into the flange on the crusher drive and the pin situated on the upper surface of the

Corn Crusher
8
crusher drive flange falls into the hole in the flange of the driving unit. Move the driving unit
slightly from side to side until it is fully seated on the gearbox case.
5. Then secure the driving unit by means of two quick-operating spring clamps.
6. Latches on the quick-operating clamps are to be hooked into notches in the rivet on lugs
of the crusher drive flange. Clip the quick-operating clamps by pushing on the clamp spring
eye down to the crusher drive surface.
* Be very careful when engaging and disengaging the quick-operating spring clamps
as your fingers might suffer an injury. The pull of the springs is great and you will
need a considerable force for clipping.
7. Removal of the driving unit is to be made in reverse order. Tilt the clamp latch away so
that it does not hamper in sliding the driving unit out from the crusher drive when removing
the driving unit from the machine.
5.4 Working with the crusher
Prior to machine use read the below information and learn how to operate the machine.
* Check the safety switch of engine ignition for its correct function.
* Prior to starting the machine, make sure that the hopper is empty and that no material is in
it which is not meant for grinding (stones, iron, plastic materials etc )
* If the machine is in operation, all other persons and animals must be outside the machine’s
working space. The operator can continue working only after they have been showed out
to a safe distance.
When starting the engine of the driving unit, you are obliged to follow instructions
contained in the respective Instructions for use of the driving unit.
5.5 Preparing raw-materials for grinding
Raw-materials meant for grinding must be free of impurities (pebbles, stones, wood etc.).
Then they are to be poured into the hopper. If the cutting knives exhibit a sudden slow-down
of revolutions (showing as a decreased engine speed), stop feeding the raw-materials into the
hopper. In a while, the engine will restore its full working speed again. Ground raw-materials
(crushed grain, cake) will fall through the sieve into a prepared vessel or bag clamped to the
crusher.
6Maintenance
To ensure a maximum satisfaction with our product, the machine must be given proper
care and maintenance. Therefore you are advised to adhere to the following instructions for
the machine maintenance:
1. Check all bolted connections for their proper tightening.
2. Make sure that all functional surfaces of the cutting mechanism are clean.
3. At the end of the season or if the machine is to be put out of operation for a longer
time, clean the machine from all dirt and impurities.

4. When cleaning/washing the machine with water, solvents or other chemicals, your are
warned to adhere to all valid regulations and laws on the protection of water courses and
other water resources against their pollution and contamination with chemical substances.
6.1 Replacement and sharpening of cutting blades
All operations described below are to be carried out either with the driving unit removed
from the machine or with the disconnected spark plug cable terminal.
Be very careful when disassembling the cutting knives – danger of cutting your fingers.
1. Having unscrewed four bolts and removed the sieve you can release the two cutting
knives.
2. Loosen and remove bolts that hold the cutting knives.
3. Turn the cutting knives by 180
o
or install freshly sharpened knives or new ones. The
blades can be refreshed by using a sharpening steel or a fine whetstone.
4. Clean the bearing surfaces and reassemble the cutting knives.
5. Install back the sieve.
Warning:
Cutting blade refreshment is an extreme possibility. It is much more useful to use a new
blade. Resharpening will change the weight of cutting knives and a considerable machine
disbalance may result in vibrations of the whole crusher. It is advised that you have always
new cutting knives on stock prepared for the case of urgency.
7Storage
Prior to any longer storage, clean the machine from all dirt and plant residues. Damaged
paint on the machine parts should be repaired. For any long-time storage it is recommended to
conserve the connecting surfaces. Access of unauthorized persons to the machine should be
prevented. The machine should be protected against weather impacts but air-tight protection
is not advised due to a possibly increased corrosion under it.
8Disposal of packaging and machine after the end of
service life
Having the machine unpacked, you are obliged to provide for the disposal of packaging
material with taking into account a possible use of secondary raw-materials according to
Waste Law No. 185/2001 Gaz. (as amended) and with respect to decrees issued by local town
or municipal authorities.
Procedure recommended for the machine disposal after the end of its service life is as follows:
1. Dismount all parts from the machine that can be still used.
2. Dismount all plastic machine parts and components made of non-ferrous metals. The
stripped machine remainder and the dismounted parts are to be disposed in compliance
with the Waste Law No. 185/2001 Gaz. (as amended) and with respect to the decrees
issued by local town or municipal authorities.
