1. A system capable of processing a mixture of drilling fluid and solid material to separate at least one component from the mixture, the system comprising: a hydrocyclone that is adapted to receive a drilling fluid mixture, the hydrocyclone comprising: a housing;an inner chamber in said housing;an inlet comprising an inlet flow channel that is adapted to allow the drilling fluid mixture to flow into the inner chamber; andan adjustment apparatus mounted adjacent the inlet, wherein the adjustment apparatus is adapted to adjust flow of the drilling fluid mixture through the inlet flow channel and into the inner chamber, the adjustment apparatus comprising:a movable closure member that is adapted to be moved so as to adjust an effective size of the inlet flow channel; anda flexible bar comprising a first end that is secured to the movable closure member and a second end that is located within and free to move with respect to a recess in said housing, wherein the flexible bar is adapted to be flexed by a flow of said drilling fluid mixture through the inlet so as to move the movable closure member in response to said flow of said drilling fluid mixture. 2. The system of claim 1 wherein the movable closure member is adapted to be moved so as to close off the inlet flow channel to flow. 3. The system of claim 1 wherein the adjustment apparatus further comprises an adjustment member that is connected to and adapted to move the movable closure member, wherein an exposed part of the adjustment member projects out from the housing, and wherein movement of said exposed part of said adjustment member moves the movable closure member. 4. The system of claim 3 wherein the exposed part of the adjustment member that projects out from the housing is manually rotatable. 5. The system of claim 3 further comprising a control system operatively coupled to the adjustment apparatus, wherein the control system is adapted to move the exposed part of the adjustment apparatus that projects out from the housing so as to move the movable closure member. 6. The system of claim 5 further comprising a first sensor apparatus operatively coupled to the housing, wherein the first sensor is in communication with the control system and is adapted to sense a pressure of the drilling fluid mixture in the inlet and provide a first signal indicative thereof to the control system, and wherein the control system is adapted to control the adjustment apparatus in response to said first signal. 7. The system of claim 6 further comprising a second sensor apparatus operatively coupled to the housing, wherein the second sensor is adapted to sense a position of the movable closure member, produce a second signal indicative thereof, and provide said second signal to the control system, and wherein the control system is adapted to control the adjustment apparatus in response to said second signal. 8. The system of claim 7 further comprising a third sensor apparatus operatively coupled to the housing, wherein the second sensor is adapted to sense a stress on the adjustment apparatus, produce a third signal indicative thereof, and provide said third signal to the control system, and wherein the control system is adapted to control the adjustment apparatus in response to said third signal. 9. The system of claim 3, wherein said adjustment member comprises a rotatable a bar shaft adjacent the second end of the flexible bar, wherein the rotatable bar shaft is a adapted to move the flexible bar so as to move the movable closure member. 10. A system capable of processing a mixture of drilling fluid and solid material to separate at least one component from the mixture, the system comprising: a hydrocyclone that is adapted to receive a drilling fluid mixture, the hydrocyclone comprising: a housing;an inner chamber in said housing;an inlet comprising an inlet flow channel that is adapted to allow the drilling fluid mixture to flow into the inner chamber; andan adjustment apparatus mounted adjacent the inlet, wherein the adjustment apparatus is adapted to adjust flow of the drilling fluid mixture through the inlet flow channel and into the inner chamber, the adjustment apparatus comprising:a movable closure member that is adapted to be moved so as to adjust an effective size of the inlet flow channel, the movable closure member being further adapted to be moved so as to close off the inlet flow channel to flow;a flexible bar comprising a first end that is secured to the movable closure member and a second end that is located within and free to move with respect to a recess in said housing, wherein the flexible bar is adapted to be flexed by a flow of said drilling fluid mixture through the inlet so as to move the movable closure member in response to said flow of said drilling fluid mixture; andan adjustment member that is connected to and adapted to move the movable closure member, wherein an exposed part of the adjustment member projects out from the housing, and wherein movement of said exposed part of said adjustment member moves the movable closure member. 11. A system capable of processing a mixture of drilling fluid and solid material, the system comprising: a hydrocyclone that is adapted to receive a drilling fluid mixture, said hydrocyclone comprising a housing;an inner chamber in said housing;an inlet comprising an inlet flow channel, wherein said inlet flow channel is adapted to allow a flow of said drilling fluid mixture into said inner chamber; andan adjustment apparatus mounted adjacent said inlet, wherein said adjustment apparatus is adapted to adjust said flow of said mixture into said inner chamber, said adjustment apparatus comprising a movable closure member that is adapted to be moved so as to adjust an effective size of said inlet flow channel, said movable closure member comprising:a first movable wall pivotably connected to said housing; anda selectively inflatable bladder abutting said first movable wall, wherein said selectively inflatable bladder is adapted to selectively move said first movable wall so as to adjust said effective size of said inlet flow channel. 12. The system of claim 11, wherein the adjustment apparatus comprises a second movable wall, the second movable wall being movable with the first movable wall. 13. The system of claim 11, further comprising a control system operatively coupled to said adjustment apparatus, wherein said control system is adapted to control said selectively inflatable bladder so as to selectively move said first movable wall. 14. A system capable of processing a mixture of drilling fluid and solid material, the system comprising: a hydrocyclone that is adapted to receive a drilling fluid mixture, said hydrocyclone comprising: a housing;an inner chamber in said housing;an inlet comprising an inlet flow channel, wherein said inlet flow channel is adapted to allow a flow of said drilling fluid mixture into said inner chamber; andan adjustment apparatus mounted adjacent said inlet, wherein said adjustment apparatus is adapted to adjust said flow of said mixture into said inner chamber, said adjustment apparatus comprising:a flexible closure member secured to a first inlet wall of said inlet; andan adjustment member contacting said flexible closure member, wherein at least a part of said adjustment member projects from said housing and is adapted to be moved in a direction that is substantially perpendicular to a direction of said flow of said drilling fluid mixture through said inlet flow channel so as to move said flexible closure member and adjust an effective size of said inlet flow channel. 15. The system of claim 14, wherein said inlet comprises a second inlet wall spaced apart from said first inlet wall, and wherein said flexible closure member is adapted to be moved by said adjustment member so as to sealingly abut said second inlet wall. 16. The system of claim 14, wherein said inlet comprises a feed end and a chamber end downstream of said feed end, wherein said chamber end is proximate said inner chamber and said adjustment apparatus is proximate said feed end. 17. The system of claim 14, further comprising a control system operatively coupled to said adjustment apparatus, wherein said control system is adapted to control said adjustment member and movement of said flexible closure member.
