882.00207.00 Chapter 3: Installation 35 of 102
The manufacturer provides all pneumatic lines on the blender piped to a single ¼” NPT standard
pipe thread fitting. The Slide Gate/Auger blending system requires approximately 1 cfm (1.7 m³/hr)
@ 60 psi (4.14 bar) maximum air pressure for proper operation.
The working pressure of the blender cylinders is not to exceed 60 psi (4.14 bar). This is adjustable
by the regulator supplied on the rear panel of the blender. It is important to prevent fluctuation in the
air pressure to the blender by not installing the unit on an airline. If this is the case, an accumulator
tank with a check valve may have to be used to ensure the blender a steady air supply.
Caution! To prevent damage to the equipment, do not exceed 60 psi (4.14 bar) air pressure.
Caution! Always disconnect the compressed air supply when working on any part of the
blender.
3-5 Initial Set-up
This section will discuss the mechanical setup and control system setup of the Slide Gate blending
system. After reading this section, you should be familiar with the mechanical setup and the
electronic control setup of the blending system.
Mechanical Set-up
Stroke Limiters for Metering Gates
Stroke limiters are supplied on components 1 through 6 with all Slide Gate blenders to allow
standard metering gates to meter small amounts of low percentage additive materials.
Generally, the stroke limiter is not required on major ingredients (usually number 1 and 3) and
should be adjusted to the rear-most position. If they are used on components number 1 and 3 the
throughput of the blender will be reduced.
To install the stroke limiter, drop it into the double slot on top of the gate assembly and secure it in
place with the button head screw that is provided. Be sure to use the lock washer to prevent the
stroke limiter from coming loose.

Weigh Hopper Installation
Remove the weigh hopper from the shipping box and install it in the blender on the load cell
brackets. Connect the airline and close the mixer door, securing the latch.
