Cone crushers with differing main bearing styles therein being manufactured with interchangeable parts and with a common exterior configuration so that a roller bearing cone crusher could be replaced at a crushing site by a plain bearing cone crusher without the need for any modification to either the plain bearing crusher or the crushing site. Methods of manufacturing roller bearing cone crushers which have components therein which are interchangeable with components in a plain bearing cone crusher is also disclosed.

Roller bearing cone crusher and plain bearing cone crusher with a common exterior configuration

A milling machine includes a frame, a housing, a milling drum mounted on the frame within the housing and a drive assembly. A positioning assembly is provided for moving the drive assembly between a first position which is laterally outside the periphery of the machine housing and a second position which is laterally inside the periphery of the machine housing, and for locking the drive assembly in at least the first and second positions without requiring the operator to manually manipulate a locking pin.

Positioning assembly for placing steerable drive in multiple positions with respect to milling machine housing

A working machine for use in milling the surface of a road includes a drive engine that produces engine exhaust gases. The working machine also includes a milling drum that is mounted for rotation against the surface of the road so as to generate milled material including dust from the road surface. The milling drum is contained within a milling chamber, and a spray assembly directs water into the milling chamber in such a manner that, during a period of rotation of the milling drum against the surface of the road, at least a portion of the water is converted to a vapor. A conduit is provided for conducting at least a portion of the engine exhaust gases into an enclosed space in communication with the milling chamber to raise the temperature of a gas stream therein containing vapor and dust from the milled material.

Method and apparatus for controlling dust emissions with temperature control

An HMA plant which uses combination direct exhaust heated and indirectly steam heated pre-heating drum in combination with a sealed indirect hot oil heated rotary shaft mixer, where the steam given off from the heated HMA is maintained, separated from the sulfur containing exhaust of a hot oil heater, so as to minimize the production of acid in liquid form.

Low emission energy efficient 100 percent RAP capable asphalt plant

A warm mix asphalt plant comprising a counter-flow drum, apparatus for precisely metering flows of A/C and water, an asphalt expander with no moving internal parts where a circular curtain of flowing clean water is mixed with a coaxial circular curtain of moving heated A/C to create asphalt foam which is heated and mixed inside a lower portion of the asphalt expander and then distributed to cover aggregate inside the counter-flow drum.

Warm mix asphalt production system and method

An HMA plant which uses incidental heating of metal surfaces in combination with hot exhaust gases to pre-heat and pre-dry virgin aggregate material contained in an enclosed container which permits hot dry air to pass through interstices in the virgin aggregate material stored in the container.

Pre-aggregate drying method and energy efficient asphalt plant

Energy efficient asphalt plant

A tack emulsion pre-coating system for use in hot mix asphalt plant paving which comprises providing a triangular-shaped tack emulsion cart deployed ahead of a paver, and configured to operate under a conveyor from a transfer vehicle supplying the paver with HMA, where the cart comprises a forward spray bar which sprays tack emulsion on a surface located between the wheels of the paver so as not to leave tracks and with rear spray bars for spraying tack emulsion behind the wheels, but not behind a central area between the wheels of the paver.

Trackless tack pre-coating system and method for hot mix asphalt paving

A multi-use asphalt paving tractor with frame raise capability and a blind-mateable connector to facilitate quick connection with interchangeable attachments for performing the functions of a paver, a mix transfer conveyor and road widener.

Frame raising multi-use paving tractor with blind mateable quick connecting tool attachments

A multi-stage modular road building equipment system where a first stage base tractor is coupled to an intermediate stage, such as a spreading screw, and a third stage screed road paving tool attachment or other attachment such as a widener.

Multi-stage modular road paving equipment and method of manufacture and sales

A method and apparatus for heating hot mix asphalt (HMA), via collecting fumes from HMA while the HMA is on-board a vehicle and in motion within the vehicle, and igniting the HMA with engine exhaust and using the heat of combustion of the HMA to heat HMA, such as via the floor of a re-mix machine or paver which is capable of churning and mixing the HMA which increases emission of HMA fumes.
