Definitions
- the present invention provides a method of making a briquette, comprising compacted particulate material, having an outer region and an inner region, said inner region being provided with a well having a diameter which decreases progressively in a non-linear relationship with increasing distance from the top of the well such that the sides of the well extend convexly into the well
- a method comprises feeding a particulate material to be compacted into the nip between a first roll and a second, counter-rotating, roll, said first roll having a surface in which is provided at least one depression mould having a mould interior, a mould exterior at the circumference of the roll and a post extending radially from the lowest portion of the mould interior to an extremity within the circumference of the roll which post has a diameter which decreases progressively in a non-linear relationship with increasing distance from the lowest portion of the mould such that the sides of the post extend concavely away from the lowest portion of the mould, compacting the particulate material in the mould as the first and second
- each half mould provided into the surface of roll 5 or into the surface of roll 6 comprises a mould interior 11 , a mould exterior 12 (at the circumference of the roll) and a post 13 which extends radially from the lowest portion of the mould interior 11.
- the post 13 does not extend to the circumference of the roll but has an extremity which is within this circumference, i.e., the distance from the axis of rotation of the roll to the end of the post is less than the radius of the roll.
- the formed briquettes fall from or are ejected from the mould as the rolls rotate downwards and the half moulds in rolls 5 and 6 separate.
- the mould interior is preferably machined to provide a release surface.
- the mould interior may be provided with a release coating.
- the moulds are designed to provide a briquette having wells which have a shape defined by an inverse hyperbolic truncated cone and a shape that is approximately toroidal it will be appreciated that other shapes can be achieved by the use of appropriately shaped moulds.
