Abstract

A crusher feed distributor for mounting at a crusher input hopper of a crusher. The feed distributor includes a guide body to contact and distribute the flow of feed material and a mounting assembly to mount the guide body at the input hopper. The mounting assembly is specifically configured with a plurality of independent mounts that collectively provide four adjustments and decrease of freedom corresponding to three lateral adjustments and one rotational adjustment.

First claim

1 . A crusher feed distributor for mounting at a crusher input hopper of a crusher, the distributor comprising:
a guide body to receive a flow of material to be crushed and to direct the flow of material into the crusher; a first mount to mount the guide body at a region of the hopper and having a first adjustment component to allow adjustment of the position of the guide body at the hopper along a first pathway such that the guide body is capable of moving in a side-to-side direction within the hopper; a second mount to mount the guide body at a region of the hopper and having a second adjustment component to allow adjustment of the position of the guide body at the hopper along a second pathway such that the guide body is capable of moving in an upward and downward direction within the hopper; and an additional mount to mount the guide body at a region of the hopper and having an additional adjustment component to provide adjustment of the position of the guide body at the hopper along a third pathway and/or rotation of the guide body about a rotational axis, the third pathway being aligned transverse or perpendicular to the first and second pathway to allow the guide body to move in a backwards and forwards direction within the hopper and/or rotation about a longitudinal axis extending through the hopper.

2 . The feed distributor as claimed in claim 1 , wherein the additional mount includes a third mount having a third adjustment component configured to allow adjustment of the position of the guide body at the hop along a third pathway aligned perpendicular or transverse to the first and second pathway such that the guide body is capable of moving in the backward and forward direction within the hopper.

3 . The feed distributor as claimed in claim 2 , wherein the additional mount includes a fourth mount having a fourth adjustment component configured to provide rotational movement of the position of the guide body about an axis corresponding to a longitudinal axis of the hopper to allow rotational mounting adjustment of the guide body within the hopper.

4 . The feed distributor as claimed in claim 3 , wherein the third and fourth adjustment components include an elongate slot formed in the respective third and fourth mount, the third and fourth mount further having a respective attachment member to slide within the respective elongate slot of the third and fourth mount.

5 . The feed distributor as claimed in claim 4 , wherein the guide body includes a first shelf and a second shelf independently mounted and adjustable at the hopper.

6 . The feed distributor as claimed in claim 5 , wherein the third mount includes a pair of elongate brackets, each bracket having a respective elongate slot to receive a respective attachment member to slide within the slot.

7 . The feed distributor as claimed in claim 6 , wherein the fourth mount includes a pair of brackets each having an elongate slot to receive an attachment element to slide within the slot each bracket of the fourth mount being configured for attachment to an upper region of the hopper.

8 . The feed distributor as claimed in claim 7 , wherein the first mount includes a pair of elongate brackets, each bracket having an elongate slot to receive an attachment element to slide within the respective slot.

9 . The feed distributor as claimed in claim 7 , wherein the second mount includes a beam slideably mounted at the pair of elongate brackets of the third mount, the end regions of the beam being respectively mounted at a region of the bracket having an elongate slot to receive an attachment element that attaches the end regions of the beam to each respective bracket to allow the beam to slide in the upward and downward direction at the hopper.

10 . The feed distributor as claimed in claim 3 , wherein the guide body is mounted at the input hopper via the fourth mount and wherein the first, second and third mounts are suspended between the fourth mount and the guide body.

11 . The feed distributor as claimed in claim 8 , wherein each bracket of the first mount is fixed rigidly to a respective bracket of the third mount such that the brackets of the first mount extends substantially perpendicular or transverse to the brackets of the third mount.

12 . The feed distributor as claimed in claim 8 , wherein the first and second shelf each include a mount region having an attachment element received within each respective elongate slot of each respective bracket of the first mount to allow each shelf to slide in the side-to-side direction within the hopper along each bracket of the first mount.

13 . A crusher input hopper of a crusher comprising a feed distributor, the feed distributor including a guide body to receive a flow of material to be crushed and to direct the flow of material into the crusher;
a first mount to mount the guide body at a region of the hopper and having a first adjustment component to allow adjustment of the position of the guide body at the hopper along a first pathway such that the guide body is capable of moving in a side-to-side direction within the hopper; a second mount to mount the guide body at a region of the hopper and having a second adjustment component to allow adjustment of the position of the guide body at the hopper along a second pathway such that the guide body is capable of moving in an upward and downward direction within the hopper; and an additional mount to mount the guide body at a region of the hopper and having an additional adjustment component to provide adjustment of the position of the guide body at the hopper along a third pathway and/or rotation of the guide body about a rotational axis, the third pathway being aligned transverse or perpendicular to the first and second pathway to allow the guide body to move in a backwards and forwards direction within the hopper and/or rotation about a longitudinal axis extending through the hopper.

14 . A gyratory crusher comprising:
a feed hopper; and a crusher feed distributor mounted at the feed hopper, the feed distributor including a guide body to receive a flow of material to be crushed and to direct the flow of material into the crusher; a first mount to mount the guide body at a region of the hopper and having a first adjustment component to allow adjustment of the position of the guide body at the hopper along a first pathway such that the guide body is capable of moving in a side-to-side direction within the hopper; a second mount to mount the guide body at a region of the hopper and having a second adjustment component to allow adjustment of the position of the guide body at the hopper along a second pathway such that the guide body is capable of moving in an upward and downward direction within the hopper; and an additional mount to mount the guide body at a region of the hopper and having an additional adjustment component to provide adjustment of the position of the guide body at the hopper along a third pathway and/or rotation of the guide body about a rotational axis, the third pathway being aligned transverse or perpendicular to the first and second pathway to allow the guide body to move in a backwards and forwards direction within the hopper and/or rotation about a longitudinal axis extending through the hopper.
