Clay silos are the only pieces of equipment that make it possible to provide absolutely homogeneous, uniformly moist press body, and precisely that is a prerequisite for wet extruded bricks with low stress and texture levels. The unique souring and homogenizing effect is achieved according to the “first in – first out” principle in combination with hermetically sealed storage and pressure from the dead weight of the raw material. HÄNDLE is the only manufacturer producing circular silos in three different sizes with capacities ranging from 110 m³ to 1000 m³. In all three, the material discharges through a centrally located hopper enabling material takeoff in any arbitrary direction. The automatic hydraulic discharger is controlled and operated via modern PLC (programmable logic control) technology, so accurate material infeed, even from remote shaping plant, is no problem. The silo tower can be made of steel, in-situ concrete, pre-fabricated concrete components or brick masonry with reinforced joints.
