Abstract
A tip holder for the rotor of a centrifugal mineral breaker with a mounting member portion and a step with a mineral anchoring portion capable of retaining a bank of mineral material in which the minerals may have a diameter of up to 100 mm. The step also has one or more recesses formed longitudinally through the step and an insert of abrasion resistant material inserted in each recess. The width of a material retaining surface of said step is approximately equal to or greater than the depth of the insert of abrasion resistant material. A plurality of longitudinally disposed parallel inserts can be placed in the tip holder to maximize its resistance to specific mineral conditions.
Claims31
An improved tip holder for the rotor of a centrifugal mineral breaker having discharge ports through which mineral material is passed out of said rotor, the tip holder comprising
- a projecting mounting member portion for removably securing said tip holder to a rotor of a centrifugal mineral breaker proximate a discharge port thereof, said mounting member portion having an inner mounting surface and an outer mineral-contacting surface, the distance therebetween being the thickness of said mounting member portion;
- a step integrally formed on one end of said mounting member portion and projecting therefrom into the path of the mineral material stream being passed out of said rotor, said step having a top surface for contacting said discharging mineral material, said step forming at least a portion of a material retaining surface disposed adjacent to said top surface and oriented toward said mounting member portion, said material retaining surface being formed for retaining a built-up bank of mineral materials extracted from the stream of mineral materials being passed out of said rotor, said material retaining surface being capable of retaining and stabilizing in said bank mineral materials having diameters of varying sizes up to 100 mm., said step also having at least one recess formed longitudinally therethrough;
- an insert of abrasion resistant material at least partially enclosed in each recess of said step;
- and
- a supporting and mineral flow-directing flange depending from the step in the general direction of the flow of discharged material.
An improved tip holder for the rotor of a centrifugal mineral breaker having discharge ports through which mineral material is passed out of the rotor, the tip holder comprising
- at least one mounting member portion for removably securing said tip holder to a rotor of a centrifugal mineral breaker proximate a discharge port thereof, said mounting member portion having an inner mounting surface and an outer mineral-contacting surface, the distance therebetween being the thickness of the mounting member portion, and mounting means proximate one end;
- a step integrally formed on the other end of said mounting member portion and projecting transversely therefrom into the path of mineral material being passed out of said rotor, said step having a top surface formed to be substantially coplanar with the surface layer of a retained bank of mineral material immediately adjacent thereto, an outer surface disposed adjacent to said to surface and shaped to direct the flow of fine particles in the mineral material stream away from said rotor, and a material retaining surface disposed adjacent said top surface and said mounting member portion, said material retaining surface formed for retaining a built-up bank of mineral materials, the width of a portion of said material retaining surface being approximately equal to the distance from the top surface of the step to the inner mounting surface of the mounting member portion, said step also comprising at least one recess formed longitudinally therethrough;
- an insert of abrasion resistant material fixed in each recess of said step;
- said material retaining surface having a width for a portion of its length which is at least as great as the depth of the insert of abrasion resistant material disposed closest to the top surface of said step;
- and
- a stabilizing and mineral flow-directing flange depending from the step and formed to direct the flow of discharge material.
An improved tip holder for the rotor of a centrifugal mineral breaker having discharge ports through which mineral material is passed out of the rotor, the tip holder comprising
- at least one mounting member portion for removably securing said tip holder to a rotor of a centrifugal mineral breaker proximate a discharge port thereof, said mounting member portion having an inner mounting surface and an outer mineral-contacting surface, the distance therebetween being the thickness of said mounting member portion;
- a step integrally formed on one end of said mounting member portion and projecting therefrom into the path of the mineral material stream being passed out of said rotor, said step having a top surface for contacting said discharging mineral material substantially across the length of said top surface, said step forming at least a portion of a material retaining surface disposed adjacent to said top surface of said step, at least a portion of the thickness of said mounting member portion also forming a portion of the material retaining surface, said material retaining surface being formed for retaining a built-up bank of mineral materials extracted from the stream of mineral materials being passed out of said rotor, said step also having at least one recess formed longitudinally therethrough;
- an insert of abrasion resistant material disposed in each recess of said step;
- and
- a supporting and mineral flow-directing flange depending from said step in the general direction of the flow of discharged material.
An improved tip holder for the rotor of a centrifugal mineral breaker having discharge ports through which mineral fastening member.
An improved tip holder for the rotor of a centrifugal mineral breaker having discharge ports through which mineral material is passed out of the rotor, the tip holder comprising
- at least one mounting member portion for removably securing said tip holder to a rotor of a centrifugal mineral breaker proximate a discharge port thereof, said mounting member portion having an inner mounting surface and an outer mineral-contacting surface, the distance therebetween being the thickness of said mounting member portion;
- a step integrally formed on one end of said mounting member portion and projecting therefrom into the path of the mineral material stream being passed out of said rotor, said step having a top surface for contact said discharging mineral material substantially across the length of said top surface, said step having a width measured from the outer mineral-contacting surface of the mounting member portion to the top surface of the step and forming a material retaining surface disposed adjacent to said top surface of said step, the width of said material retaining surface for at least a portion of its length being at least as great as the thickness of the mounting member portion, said material retaining surface being formed for retaining and stabilizing a built-up bank of mineral materials extracted from the stream of mineral materials being passed out of said rotor, said step also having at least one recess formed longitudinally therethrough;
- an insert of abrasion resistant material disposed in each recess of said step;
- and
- a supporting and mineral flow-directing flange depending from said step in the general direction of the flow of discharged material.
The improved tip holder of claim 39, 23 or 25 wherein the mounting member portion has a free end in the form of a projection extending from the step, said mounting member portion having an aperture in said free end for receiving a fastening member, said free end having a width across the outer surface thereof which is smaller than the length of the top surface of said step whereby the material retaining surface includes a portion of the thickness of the mounting member portion.
