A method of producing titanium cobbles includes: a preparation step of preparing a scrap material containing 50% by mass or more of metal titanium; a first crushing step of roughly crushing the scrap material using a first crusher; a second crushing step of crushing the scrap material, which has been roughly crushed in the first crushing step, using a second crusher; a dust collection step of collecting fine dust of the scrap material generated in the second crushing step; and a first classification step of classifying products obtained by crushing the scrap material, which have been generated in the second crushing step, into medium particles with particle sizes within a predetermined particle size range, large particles with particle sizes larger than the particle size range, and small particles with particle sizes smaller than the particle size range.

A rock separator for separating rocks from soil, where the rock separator includes a mounting plate a plurality of elongate tines secured to the mounting plate, where the plurality of elongate tines define a curved shape across the mounting plate, a plurality of support members laterally joining the plurality of elongate tines and an attachment bracket on the mounting plate for releasably mounting to a machine. The mounting plate has a first major surface and a second major surface opposite the first major surface. The attachment bracket is attached directly to the mounting plate, where the plurality of elongate tines do not move relative the attachment bracket.

One embodiment of a bucket drill and soil screen apparatus consists of a mast (9) attached to a prime mover vehicle (7). A carriage (10) and hydraulic motor (12) slide vertically along the mast from which an attached kelly bar (14) and drilling bucket (15) are rotated and lowered into the ground. A kickout assembly (13) lifts drilling bucket (15) outward in an arc. Soil and cultural artifacts are transferred to a screen basket (20) by rotating open the drilling bucket through a latch and hinge. The screen basket is lifted to its screening position and rotated around a central axis to facilitate the passing of fine soil particles through the hardware cloth walls of the basket. Cultural artifacts retained in the screen basket are transferred to a fixed sorting screen (22) by rotating the screen basket to its dump position.

A mobile aggregate processing plant for screening material including a chassis and a vibrating screen support frame, and a vibrating screen mounted on the support frame, wherein the vibrating screen has an infeed end and a discharge end, and able to provide at least one material discharge stream therethrough. A feed hopper has a discharge end able to feed a stream of feed material into or onto the vibrating screen. A shredding apparatus is moveable between at least a first in use position above the infeed end of the vibrating screen and/or next to the hopper discharge end, and a second transport position not above the infeed end of the vibrating screen and/or not next to the hopper discharge end.

A screening assembly for screening material includes an assembly frame, a multi-deck screening device, a transfer conveyor and a drive means. The drive means is operable to shift at least one of the discharge ends of the screening device and the receiving end of the conveyor relative to the assembly frame to allow the transfer conveyor to selectively receive material from an upper screen and from both screens of the screening device at their respective discharge ends. A mobile material processing plant incorporating the screening assembly is included.
