Saxlund International’s original Sliding Frame discharge system was developed and patented in 1972.
The Sliding Frame covers the entire silo bottom and discharges the layers of material in the order in which they were introduced into the storage silo, i.e. first in – first out! The Sliding Frame pushes the stored material into one or more openings in the silo bottom thereby creating “mass flow” which eliminates bridging and allows the material to flow at the desired maximum rate.
The Sliding Frame silo discharge system has no moving parts within the silo other than the reciprocal movement of the frame itself. The result is that no direct wear or machine element can come loose and cause damage within the silo or downstream equipment. Maintenance accessibility is enhanced since all the serviceable parts are accessible from the outside of the silo.
The heavy-duty Push Floor is specifically designed for heavy wet and non free-flowing materials.
The design eliminates the typical rear wall packing problem often found in rectangular bunkers and the material is always delivered on a first in – first out basis.
The Push Floor can be used to discharge the stored material to any number of feeder/metering systems including screw conveyors, sludge pumps, belt conveyors or chain conveyors.
Saxlund International has supplied many plants durable and reliable solids handling pumps throughout the world. Many different types of sludge can be pumped economically, including high solids content. An advantage of these systems is that they are closed to eliminate odour and corrosion.
A wide range of pump capacity is available. The pumps are easily maintained and enjoy very high availability. Saxlund International holds several patents for equipment used for sludge handling.
Saxlund International has developed proprietary mechanical conveying equipment specially designed for sludge. This equipment includes chain conveyers and several different types of screw conveyors.
As an example, Saxlund recently delivered a complete system for handling 75 m3 sludge per hour. This equipment included a Push Floor, Sliding Frame, chain conveyers and screw conveyors.
