Bowl and mantle assembly for cone crushers

Claim 2

A removeable liner assembly for the bowl of a gyratory crusher having a plurality of hooking members adapted to receive and retain the liner assembly, comprising: a. a backing plate essentially taking the form of a truncated cone with a central opening therein and made from material having a predetermined resistance to abrasion; b. a plurality of wear segments constructed for mounting on the backing plate and collectively defining a crushing surface, each segment formed from material having a resistance to abrasion greater than that of the backing plate; c. said backing plate having an opening for each of said wear segments; d. each wear segment having a lug member disposed on the backside thereof, each lug member constructed and arranged to project through its associated opening in the backing plate for retaining engagement with one of said hooking members; e. and each wear segment being secured to the backing plate with a resilient adhesive.

Claim 3

The liner assembly defined by claim 1, wherein the resilient adhesive is urethane.

Claim 4

The liner assembly defined by claim 1, wherein the wear segments are formed from martensitic white iron.

Claim 5

The liner assembly defined by claim 1, wherein the wear segments are constructed and arranged on the backing member to define a gap between adjacent segments, said gaps being filled with said resilient adhesive to secure adjacent segments to each other.

Claim 6

The liner assembly defined by claim 1, wherein each of said lug members further comprises a shoulder portion disposed at its base for abutting engagement with the wall defining said opening.

Claim 7

The liner assembly defined by claim 1, wherein one of said backing plate and wear segments has ridge means disposed thereon for sPacing the respective segments from the backing plate, the resilient adhesive being disposed in said space.

Claim 8

The liner assembly defined by claim 6, wherein the ridge means are disposed on the back side of said wear segments, comprising a ridge extending around at least a portion of the periphery of said segment back side.

Claim 9

A removeable liner assembly for a gyratory crusher having a conical bowl and mantle relatively moveable in gyratory fashion, the liner assembly constructed for use with one of said bowl and mantle and comprising: a. a backing plate essentially taking the form of a truncated cone with a central opening therein and made from material having a predetermined resistance to abrasion; b. a plurality of wear segments constructed for mounting on the backing plate and collectively defining a crushing surface, each segment formed from material having a resistance to abrasion greater than that of the backing plate; c. one of said backing plate and wear segments having a plurality of lugs of predetermined size and shape projecting therefrom; d. the other of said backing plate and wear segments having a like number of recesses conforming in size and shape to the projecting lugs and disposed for cooperative engagement therewith; e. and said wear segments being secured to the backing plate with a resilient adhesive.

Claim 10

A removeable liner assembly for a gyratory crusher having a conical bowl and mantle relatively moveable in gyratory fashion, the liner assembly constructed for use with one of said bowl and mantle and comprising: a. a backing plate essentially taking the form of a truncated cone with a central opening therein and made from material having a predetermined resistance to abrasion; b. a plurality of wear segments constructed for mounting on the backing plate and collectively defining a crushing surface, each segment formed from material having a resistance to abrasion greater than that of the backing plate; c. one of said backing plate and wear segments having a plurality of lugs of predetermined size and shape projecting therefrom; d. the other of said backing plate and wear segments having a like number of recesses conforming in size and shape to the projecting lugs and disposed for cooperative engagement therewith; e. and said wear segments being secured to the backing plate with a resilient adhesive.

Claim 11

The liner assembly defined by claim 8, wherein the depth of said recesses is less than the projecting dimension of each of said lugs to effect spacing of the wear segments from the backing plate, the resilient adhesive being disposed in said space.

Claim 12

The liner assembly defined by claim 8, wherein the projecting lugs are disposed on the backing member in circular rows.

Claim 13

The liner assembly defined by claim 1, wherein the wear segments are arcuately shaped and identically sized to collectively define a truncated conical crushing surface.

Claim 14

The liner assembly defined by claim 1, wherein the wear segments are formed from martensitic steel.

Claim 15

The liner assembly defined by claim 8, wherein the resilient adhesive is urethane.

Claim 16

The liner assembly defined by claim 8, wherein the wear segments are formed from martensitic white iron.

Claim 17

The liner assembly defined by claim 8, wherein the wear segments are formed from martensitic steel.

Claim 18

The liner assembly defined by claim 8, wherein the wear segments are constructed and arranged on the backing member to define a gap between adjacent segments, said gap being filled with said resilient adhesive to secure adjacent segments to each other.

Claim 19

The liner assembly defined by claim 8, wherein the wear segments are arcuately shaped and identically sized to collectively define a truncated conical crushing surface.
