Method and apparatus for metering and distributing pouring material, especially for the production of mineral-bonded particle boards

Apparatus for distributing and metering pouring material in a downstream direction from a primary supply bunker containing the pouring material to a mould conveyor, the apparatus comprising

• a conveyor belt for accepting pouring material from the primary supply bunker,
• measurement means coupled to the conveyor belt for determining the amount of pouring material on the conveyor belt,
• a metering device disposed downstream from the measurement device for providing a metered amount of pouring material to the mould conveyor, and
• reciprocating means for supplying the pouring material in a metered manner to the conveyor belt during the course of time as well as distributed over the width of the conveyor belt.

A method for metering and distributing pouring material comprising the steps of

• depositing a volumetrically metered portion of the pouring material at a measurement site,
• measuring the quantity of the metered portion of the pouring material at the measurement site, thereby providing a pouring material measurement, and
• metering, in response to the pouring material measurement, the metered portion of pouring material, thereby forming a redistributed quantity of pouring material,
• distributing the redistributed quantity of pouring material on a mould conveyor.

Apparatus for distributing and metering pouring material in a downstream direction from a primary supply bunker to a moulding conveyor, said apparatus comprising

• reciprocating means disposed to receive pouring material from the primary supply bunker,
• a conveyor belt for accepting a metered quantity of pouring material from the reciprocating means,
• a measurement device coupled to the conveyor belt for providing a measurement of the pouring material on the conveyor belt, and
• metering means for distributing the pouring material on the conveyor belt onto the mould conveyor.
