Embodiment Construction

[0147] According to the invention, a system 10 for forming compacted articles by compacting powders or granules comprises:

[0148] Powder discharge assembly 12;

[0149] A cavityless compression assembly 20 comprising:

[0150] a bottom plate 22 substantially the same size as or larger than the compacted product,

[0151] Confinement tools to separate a portion of the powder,

[0152] top punch 24; and

[0153] Conveyor 14 for transporting powder.

[0154] 1. Custom design vibrating feeder / powder discharge assembly / vibrating feeding tool

[0155] In a preferred embodiment of the invention, the powder discharge assembly 12 includes a vibrating feeder, such as a hopper, which is filled with particulate fly ash or other ceramic composition. The outlet of the feeder is equipped with an oscillating comb 46 through which powdery and granular material falls uniformly onto a belt or any other type of conveyor 14 . The combs move parallel to each other to prevent accumulation of...

Abstract

The invention relates to a method and a system (10) for forming pressed articles by pressing powder or granules, the system comprising the following apparatuses: a powder discharge assembly (12); a no-cavity press assembly (20) including: an bottom plate (22) that is the same size or greater than the pressed articles, a constraining means to isolate a portion of powder, and a top punch (24); and a conveyor (14) to transport the powder and / or pressed articles.

Description

technical field [0001] The present invention relates to devices, systems and methods for compacting powders, particularly for forming floor and wall tiles from compositions comprising fly ash. Background technique [0002] Ceramic powders are typically formed into bricks and other compacted articles by depositing a spray-dried clay-based powder into a cavity in which the powder is compacted into a compressed shape. This is known in the art as dry forming. The powder is deposited into the cavity by a number of different methods including conveyors, single batch hoppers and multi-batch hoppers. [0003] Commonly used charging hoppers are vibrating funnel-shaped transfer containers that deposit the spray-dried granules directly into the chamber, or onto single-batch, volume-measured transfer trays. In each deposition, the spray-dried granules in the hopper were shaken down to the bottom of the hopper near the hopper outlet door. When deposition occurs, the hopper is opened a...
