1. General Description
Read this manual carefully before operation to prevent damage of the
machine or personal injuries.
SGB series gravimetric blender can be used in the fields of injection molding
machines, blow molding machines and extrusion lines for proportionally precise
mixing of several types of material. This series machines adopt Becca levy PLC
controller and latest ingredients calculation methods. The machine is controlled by
an advanced microprocessor with a digital display that is simple to calibrate. The
self-compensation and calibration function ensure accurate material dosing
percentages. A high precision electronic weighing scale is used to ensure precise
weighing of every batch and ensure accuracy to ±0.1%~0.3%. There are 8 models
available to be selected based on various materials and throughputs. (This series
are not suitable for powder and sheet pieces weighing)
Model: SGB-200-4(Machine Mount)

1.1 Coding Principle
1.2 Feature
1) Standard configuration
 The micro-scale metering accuracy is ±0.1% when all materials are
blended through gravity.
 Auto calibration function which is performed every time after material
weighting ensures best proportioning accuracy.
 Up to 100 recipes can be stored for future use.
 Have alarm history record function.
 SGB-600 and models below are directly mounted on machines.
 For SGB-1200 and models above, floor stand is the standard supply
(equipped with floor stand, material storage tank and pneumatic discharge
valve).
 Adopt Ethernet communication function to realize online centrally monitor
function.
 With function of material auto-suction control.
2) Accessory option
 Hopper low material level sensor is optional for advance warning when
lacking materials.
 Floor stand, pneumatic discharge valve, storage bin and suction box should
be equipped for floor mounting. (Applicable for SGB-600 and models
below).
 Vacuum generator SVG and central hopper receiver SHR-U-ST are
optional.

11(73)
 Microscale metering valve is optional for SGB-40/200/600 to meter
materials with proportion of 0.2%-0.5%.
 Special material metering valve is optional for metering sheets or irregular
materials whose diameters are within 12×12×12mm.
 Optional data-collection function can read actual additive proportion, output,
all kinds of materials' total amount and output rate of every lot of virgin or
recycling material, master-batch and additives.
 Function of recycled material auto-compensation is optional (recycling
hopper should option with low level switch).Aberration compensation can
be automatically calculated according to the discharging amount of
recycled materials.
All service work should be carried out by a person with technical training or
corresponding professional experience. The manual contains instructions for both
handling and servicing. Chapter 6, which contains service instructions intended for
service engineers. Other chapters contain instructions for the daily operator.
Any modifications of the machine must be approved by SHINI in order to avoid
personal injury and damage to machine. We shall not be liable for any damage
caused by unauthorized change of the machine.
Our company provides excellent after-sales service. Should you have any problem
during using the machine, please contact the company or the local vendor.

attached to it.
In the event of loss or damage to a key of a trapped key interlocking device, the
complete key lock unit shall be replaced.
1.4.2 Safety Signs and Labels
Electrical installation should be done by qualified electricians. Turn off the
main switch and control switch before servicing and maintenance.
Warning! High voltage!
The sign is attached on the cover of control box!
Warning! Be careful!
Be more careful at the place where this sign appears！
Feeding strip materials can give rise to an entanglement hazard.
Attention！
No need for regular inspection because all the electrical parts in the
control unit are fixed tightly！
