  • the crusher includes the usual driving means for rotating an eccentric mounted around the lower portion of the shaft and used to gyrate the shaft for the crushing of a stone or rock delivered through the spider into the space between the mantle and the bowl liner. Since the features of the present invention relate essentially to the upper portion of the crusher and is concerned with the suspension of the crusher shaft, the other parts of the crusher are not illustrated or described.
  • the portions of the crusher as shown in FIG. 1 comprise the frame casting 10 onto which the spider casting 12 is bolted.
  • the spider comprises the usual spaced arms 14 which extend upwardly and inwardly where they merge into the spider hub 16.

  • This flange has a horizontal annular surface 28 which serves as a seat for a unitary annular casting 30.
  • the formation and arrangement of the cylindrical section 24' and flange 26 is such as to position the annular casting 30 which is provided with a multiplicity of cylinders 32 uniformly spaced around the spider of the crusher.
  • the cylinders 32 are formed by boring the annular casting from above, and this casting 30 is secured to the flange 26 by means of stud bolts 34 threaded into the bottom of the casting at appropriate intervals.

  • Each piston is connected by a bolt 42, threaded into the top of the piston, to an annular outwardlyextending flange 44 of an adjustment header 46.
  • the bolts 42 respectively extend through spacer sleeves 48 of the same length located between the respective pistons and the adjustable header. Castle nuts 50 are threaded down on the bolts 42 to provide a uniform compression strain on the sleeves 48.
  • the lower portion of the adjustment header 46 includes an outer cylindrical bearing surface 52 slidable on the bearing surface provided by the inner cylindrical wall of the spider cylinder 24.
  • One or more vertical keys or splines 53 are mounted in grooves in the inner surface of the cylinder 24 and are received in matching grooves in the bearing surface 52 to prevent rotational movement of the adjustment header 46.
  • the lower part of the adjustment header 46 is provided with an inwardly-projecting heavy annular flange 54 for supporting and suspending the shaft 18.
  • the flange 54 is fitted with and supports a ring 56 having an upper convex spherical surface engaged by the lower concave spherical surface of a shaft suspension ring 58 fitted on the upper part of the shaft 18 and keyed thereto by a key ring 60 which extends into an annular groove in the upper part of the shaft 18.

  • the eccentric movements of the upper end of the shaft 18 are accommodated by the spherical seats on the members 56 and 58.
  • the lower parts of the cylinder 32 of the entire annular casting 30 are interconnected by passageways 62 to provide for the distribution of hydraulic fluid under equal pressure to all of the cylinders.
  • Hydraulic fluid is admitted to the cylinders 32 by a relatively large supply pipe 64 connected into the lower part of the casting 30 at the bottom of one of the cylinders 32, as shown to the right in FIG. 1.
  • This pipe 64 extends down along one of the spider arms 14 and is connected into the hydraulic fluid supply system shown diagrammatically in FIG. la.
  • the cylinders 32 are connected at the top by means of notches or passageways 66 connecting adjacent cylinders so that loss of fluid from any of the cylinders 32 will eventually flow around to an overflow pipe 68 connected into one of the cylinders slightly below the top, as shown at the right in FIG. la.
  • the pipe 68 conducts this bydraulic fluid to a hydraulic fluid supply tank 70 as indicated.
  • the hydraulic fluid supply system as shown at the right in FIG. la includes the supply tank 70 connected to the intake of a pump 72 driven by an electric motor 74.
  • the pump 72 is connected to deliver the hydraulic liquid into the pipe 64 and is adapted to provide sufficient pressure in cylinders 32 to raise and maintain the crusher shaft and crushing mantle head at the desired height under normal operating conditions.
  • a solenoid operated valve 76 is located in the pipe 64 downstream of the outlet of the pump 72.
  • the pump 72 operates continuously with hydraulic fluid flowing through the valve 76 and piping 77 back into the reservoir.
  • the solenoid valve 76 is operated directing hydraulic fluid to flow through pipe 64 to the cylinders 4 32 and in turn raise the shaft 18 and crushing head to operating position.
  • An accumulator tank 78 is connected into the supply line 64 downstream of the valve 76 by a pipe 80.
  • This tank is provided with a piston 82 and is initially charged with nitrogen through a valved line 84 so that under normal operating conditions the tank is completely filled with nitrogen at a pressure of 700 pounds per square inch.
  • the pipe connected into the accumulator tank 78 is provided with a pressure-responsive solenoid valve 86, so that if the pressure applied by the pistons 40 in the cylinders 32 exceeds a predetermined limit point, due to the presence of tramp iron or other uncrushable objects in the crushing cavity, valve 86 will be opened and hydraulic fluid will be displaced into the accumulator 78, thereby allowing the shaft and crushing head to drop sufliciently to permit the tramp iron to discharge from the cavity. As soon as this happens the pressure of the hydraulic fluid in the system will return to normal, since the excess hydraulic fluid forced into the accumulator 78 will be driven back into the cylinders 32, thereby raising the shaft and crushing head to its normal crushing position.
  • a control switch 88 located within the adjustment header 46 and operable by an adjustable actuating means 90 mounted on a control ring 92 located slightly above the shaft 18 and supported by three brackets 94 extending upwardly and attached to the top of the adjustment header 46.
  • the control switch 88 which is biased to closed position but normally held open by the actuating means 90, is mounted on a verticallyadjustable gauge bar 96 extending through an opening in control ring 92 and also through a switch cover plate 98 fitted in the top of the adjustment header cap 38.
  • the control switch 88 and mounting bar 96 are vertically adjustable by means of a threaded rod 100 secured to the switch mounting, extending through the cover plate 98 and provided with a nut 101 secured thereto.
  • the rod 100 is rotatable in the switch mounting and is threaded up or down in the nut 101 by means of a handle 102.
  • a remote control may be provided to make the adjustment.
  • the upper ends of the switch mounting means 96 and rod 100 are covered by an enclosure 103 provided with a removable cap 104.
  • the switch 88 is electrically connected through current leads 106 and 108 through a current supply source 110 with the solenoid valve 76.
  • the current leads 106 and 108 extend through an electrical cable casing 112 into a junction box 114 and through a cable line 116 to the switch 88. Electric current is supplied from the current supply leads 110 to the motor 74 by connections 120, one of which is provided with an off-on switch 122.
  • the hydraulic system advantageously includes a check valve 124 in the pipe 64 between the solenoid valve 76 and pipe 80, a relief line 126 provided with a pressure reducing valve 128 connected to discharge hydraulic fluid from the pipe 64 to the reservoir, a relief line 130, provided with a hand valve 132 and having connections for direct flow from the pipe 64 downstream of check valve 124 to the reservoir 7 0, and a relief line 134, provided with a hand valve 136, connected for discharge of hydraulic fluid from the accumulator 78 and the line 80* above the valve 86 into the reservoir 70.
  • the solenoid valve 86 is connected by one lead 138 with the current lead 106 which in turn is connected with one of the current supply leads 110 through a start and stop switch 140.
  • a second lead 142 connects the valve 86 with a pressure switch 144 responsive to the pressure in the pipe 64.
  • a current lead 146 completes the circuit to the other current supply lead 110.
  • the height of the adjustment header 46 and of the shaft 18 may be adjusted upwardly by raising the control switch 88 relative to the adjustment header 46 and the means 90.
  • the switch 88 As the switch 88 is raised slightly it closes and causes actuation of the solenoid valve 76 to cut off the flow through the pipe 77 and direct the flow through the pipe 64 and check valve 124 so that additional hydraulic fluid is pumped into the cylinders '32.
  • the actuating means 98 is also raised and at the selected height opens the switch 88, thereby changing the solenoid valve 76 to put the pump on closed cycle.
  • the shaft 18 and the adjustment header 46 may be lowered by opening the hand valve 132, so that hydraulic fluid flows from the cylinders 32 through pipes 64, 80, 138 and 77 into the reservoir 70.
  • Such an emergency may occur if the crusher has been stalled by overloading and is loaded with stone.
  • the lowering of the crusher shaft 18 and crushing head permits the clearing of the crusher cavity without digging out the stone by hand.
  • the switch 88 is permitted to close and actuate valve 76, but the hydraulic fluid delivered by the pump 72 through the valve 76 into the pipe 64 will merely flow through the pipes 88, 130 and 77 back into the reservoir 70. If the crusher is to be out of operation for long, the switches 122 and 140 are opened.
  • the pressure setting initially made by turning the adjusting screw 1% may be changed to compensate for wear of the crushing members by turning the screw 100 upwardly to raise the switch 88.
  • the bar 96 on which the switch is mounted may be graduated as shown for the purpose of measuring the amount of any adjustment to be made in the height of the shaft 18.
  • the shaft 18 Under normal operating conditions, with the crusher shaft 18 supported and suspended by the hydraulic fluid in the cylinders 32, the shaft 18 is automatically maintained at approximately the predetermined crushing height setting, but is automatically permitted to move downwardly by operation of the safety system when an uncrushable object, such as a piece of tramp iron, comes between the crushing elements and applies a high pressure to the hydraulic fluid in the cylinders.
  • the downward movement of the shaft 18 under such conditions is effected suddenly when the pressure on the hydraulic fluid in the cylinders 32 and pipe 64 reaches about 1000 pounds per sq. in., the operating pressure for which the switch 144 is set to open the solenoid valve 86.
  • this valve opens at this high pressure, hydraulic fluid from the cylinders rushes into the accumulator 78 and permits the downward movement of the shaft 18.
  • the pressure applied by the shaft 18 is reduced and the highly compressed nitrogen in the accumulator 78 forces hydraulic fluid back into the cylinders 32, so that the shaft 18 is raised quickly to its normal height.
  • the switch 144 is set to open at 400 pounds per sq. in., a pressure somewhat above that normally required in the cylinders 32 to keep the crusher shaft in crushing position.
  • the solenoid valve 86 is biased to closed position and it therefore closes when the switch 144 opens.
  • the switch 88 above the shaft 18 closes, but means is provided so that the actuation of the solenoid valve 76 is prevented and excess hydraulic fluid is not pumped into the pressure side of the system.
  • Closing of the pressure switch 144 sends electric current from the current lead 142 through a current lead 148, including a relay 150, which opens a normally closed switch 152 in the current lead 108 connected into the solenoid valve 76.
  • the relay is de-energized and the switch 152 closes, restoring the circuit for the normal operation of the solenoid valve 76 by the switch 88.
  • the solenoid valve 76 is normally biased to direct the flow from the pump in closed cycle through the pipe 77 and back to the reservoir 70.
  • the pipe 126 containing the pressure relief valve 128 is provided for emergency purposes for relief of hydraulic fluid from the cylinders 32, the valve 128 being set to open at a pressure of 1100' lbs. per square inch. However, under most conditions, since the switch 144 opens the solenoid valve 86 at 1000 lbs. per square inch, the piping leading to the accumulator cylinder 78 should be able to accommodate the flow of hydraulic fluid from the cylinders 32. Sudden extreme pressures, however, may cause the relief valve 128 to open momentarily.
  • the pipe 134 containing the valve 136 is provided for the purpose of relieving excess hydraulic fluid from in front of the piston 82 when the solenoid valve 86 is closed.
  • the piston 82 Under normal operating conditions, the piston 82 is at the extreme left end of the cylinder 78 and held there by the compressed nitrogen in the cylinder.
  • the accumulator cylinder 78 is, therefore, always in the ready condition and has a capacity for receiving all of the hydraulic fluid dumped suddenly from the cylinders 32.
  • the safety arrangement provided in the system, including the accumulator cylinder 78, the solenoid valve 86 and the pressure-responsive switch 144, is always available to protect the crusher from damage which might result from an uncrushable object coming between the crushing elements, and to restore the crusher shaft to its normal operating position the instant the uncrushable object passes from between the crushing elements of the crusher.
  • FIGS. 1 and la While the control system, as shown in FIGS. 1 and la has been described in connection with the use of certain electrical circuits for effecting operation of valves and other elements, it is to be understood that a pneumatic or hydraulic system may be used to effect the various operations and be responsive to the movements of the crusher shaft. It is also to be understood that instead of providing the cylinders 32 in a single annular casting, individual cylinder units may be used and approprlate interconnections provided.
  • the crusher construction and automatic system provided by the present invention has the advantage that in the use of the multiple piston and cylinder arrangement surrounding the upper portion of the crusher shaft, the bolts 42 are used for positioning only and take no load under any conditions. The entire load is carried by the sleeves 48 surrounding the bolts and they are in compression at all times. Furthermore, the multiple piston and cylinder arrangement makes it possible to provide close tolerances between pistons and cylinders,
