Process for pelletizing sorptive mineral fines

Claim 2

In a process utilizing absorbent pellets for the purpose of absorbing liquids and then handling or disposing of such liquids through the medium of such pellets, said pellets being identified by the process of manufacturing the same, which said latter process takes sorptive mineral fines having open pore spaces and including fine particles that will pass through a 20 mesh screen to make pellets which have a liquid absorption capacity substantially equal to that of said fines, said manufacturing process for said pellets comprising mixing said fines with water to moisten the same and substantially fill said open pore spaces with water, then forcing said moistened fines through a die in pelletizing apparatus to compactly form the moistened fines into a coherent mass of material while avoiding the forcing of water from said pore spaces, cutting said coherent mass of material to form pellets, and the step of evaporating the water from said pellet pore spaces to render said pore spaces open for subsequent absorption of liquid when it is applied to said pellets, said utilizing process comprising the steps of bringing together said absorbent pellets produced from said fines and a liquid to be absorbed, permitting said pellets to absorb said liquid, and thereafter handling the pellets in a manner which takes care of said liquid absorbed thereby.

Claim 3

In the process defined in claim 1 for the utilization of said absorbent pellets there described with said step of bringing together said pellets and a liquid by spreading said pellets over oil and grease on a floor, permitting said pellets to absorb said oil and grease, and thereafter handling the pellets by sweeping them off said floor to thereby remove said oil and grease from said floor.

Claim 4

In the process defined in claim 1 for the utilization of said absorbent pellets there described with said step of bringing together said pellets and a liquid by placing said pellets in an animal toilet box, permitting said pellets to absorb animal excretions in said box, and thereafter disposing of said pellets with animal excretions therein to dispose of said excretions.

Claim 5

In the process defined in claim 1 for the utilization of absorbent pellets there described in bringing together said pellets and a liquid chemical of a type such as herbicides and insecticides and handling such a chemical comprising the steps of absorbing such a chemical by said pellets, and thereafter distributing said pellets as carriers for the distribution of such a chemical to whatever use is desired for said chemical.

Claim 6

In the process defined in claim 1 for the utilization of said absorbent pellets there described in bringing together said pellets and a liquid comprising the steps of bringing together a color material and said absorbent pellets to decorate said pellets, and thereafter handling said pellets in a manner such as to use them for decorative mulch and ground cover.

Claim 7

In a process as defined in claim 1 for the utilization of said pellets there described as manufactured from sorptive mineral fines to a controlled pellet size to be used in the application of a chemical of a type such as a herbicide or an insecticide, comprising the steps of combining such a chemical with said pellets, and thereafter distributing said latter pellets as carriers for the application of such a chemical for its intended use.

Claim 8

In a process utilizing absorbent pellets for the purpose of absorbing liquids and then distributing such liquids by means of the distribution of said pellets with the liquid absorbed thereby, said pellets being identified by the process of manufacturing the same, which said latter process takes absorptive mineral fines having open pore spaces therein, mixing said sorptive mineral fines in a mixing apparatus with water to moisten said sorptive mineral fines and to substantially fill said open pore spaces with water and also mixing with said sorptive mineral fines a chemical of a type such as an insecticide or a herbicide, forcing said moistened sorptive mineral fines having such a chemical therewith through a die in pelletizing apparatus to compactly form said sorptive mineral fines into a coherent mass while avoiding the forcing of said water from said pore spaces, cutting said coherent mass of material to form pellets therefrom with said chemical in the material of said pellets, and evaporating the water from said substantially filled pore spaces within said pellets to render said pore spaces open and provide said pellets with liquid absorption capacity substantially equal to that of said fines from which the pellets are manufactured, said process for utilizing said absorbent pellets so manufactured, including the step of distributing the said pellets to apply said chemical in said pellets for its intended use as an insecticide or a herbicide.

Claim 9

In a process utilizing absorbent pellets for the purpose of absorbing liquids and then distributing such liquids by means of the distribution of said pellets with the liquid absorbed thereby, said pellets being identified by the process of manufacturing the same, which said latter process takes absorptive mineral fines having open pore spaces therein, mixing said sorptive mineral fines in a mixing apparatus with water to moisten said sorptive mineral fines and to substantially fill said open pore spaces with water and also mixing with said sorptive mineral fines a chemical of a type such as an insecticide or a herbicide, forcing said moistened sorptive mineral fines having such a chemical therewith through a die in pelletizing apparatus to compactly form said sorptive mineral fines into a coherent mass while avoiding the forcing of said water from said pore spaces, cutting said coherent mass of material to form pellets therefrom with said chemical in the material of said pellets, and evaporating the water from said substantially filled pore spaces within said pellets to render said pore spaces open and provide said pellets with liquid absorption capacity substantially equal to that of said fines from which the pellets are manufactured, said process for utilizing said absorbent pellets so manufactured, including the step of distributing the said pellets to apply said chemical in said pellets for its intended use as an insecticide or a herbicide.
