RMB KNOVATECH Slide Gates
are made for a wide variety ofapplications.
Each application has a unique set of design variables which will impact the
design of the gate. Variables such as the opening size, product density, head
material on the gate, and even the type of service the unit will be subjected to
an impact on the construction of the slide gate.
One of the most important, and often overlooked, design elements of a slide gate
actuator. Correctly sizing the actuator is a key component in the design of a

opening and closing force is essential for proper operation.
The force required to open and close a slide gate is a function of the size of
opening, the type of bulk material in the bin or hopper above the gate, the head
of material on the slide plate and the design of the slide gate. When the slide
gate is in
the closed position, there is a vertical force pushing down on the slide plate

The force to open the slide gate must be calculated using the coefficient of
friction between the material and the slide plate and the slide plate to the
Note: In many cases a slide gate will not be able to close through a static
