Benefits of technology

The present invention provides a binder formulation that can agglomerate or bind dispersed particles or fines into a granular composition with desired properties such as increased hardness or crush resistance, increased roundness, and increased durability. This binder formulation also acts as an in situ chelating agent for micronutrients and allows for single-stage granulation processing. The granules produced using this binder formulation and processing method are of improved quality with enhanced properties. Additionally, the invention provides a process for agglomerating dispersed particles or fines into spherical and crush resistant granules using a single-stage process. The resulting product exhibits the desired properties of increased hardness or crush resistance, increased sphericity or roundness, and increased durability. Furthermore, the binder formulation used in this process has been found to produce an anti-caking effect when used in conjunction with urea as the active agent in the granules.

Problems solved by technology

Conventional binders do not contribute either economical or practical value to the fertilizer formulations.
Thus, it is a cost ineffective component.
In some cases, the use of a binder in a fertilizer composition also results in a granular fertilizer that is insufficiently hard and / or round.
These granular fertilizers make encapsulation with polymers or resins difficult, resulting in inconsistent slow release fertilizers.
Additionally, these binders constitute a significant portion of the fertilizer composition, resulting in a fertilizer with reduced nutrient value.
Due to these shortcomings, fertilizers using conventional binders result in products with low commercial viability.

[0048](A) General Process for Preparing the Agglomerated Particles.

[0049]The granulation process is conducted at ambient temperatures and therefore can be used for fertilizer and pesticide combinations, as well as biological materials such as seed.

[0050]Granules of the invention initially require all materials in the formulation to be sized in powder form with an approximate size of 20-40 SGN. All particle components, such as fertilizers, micronutrients, seeds, and perlite are mixed together to form a relatively uniform particle blend. This blending process ensures that the mixture is thoroughly mixed. The particle blend is then feed into a granulator apparatus at ambient temperature and normal humidity.

[0051]As the mixed powder blend enters the granulator, typically a horizontal rotating drum, the binder solution (i.e., lignosulfonate and polyols) is applied at a temperature range of 110-130° F. and solution viscosity of 10-20 cps. The viscosity of the binder solution allows for at...

Abstract

The present invention relates to a novel, dual purpose binder formulation or system. The invention also relates to a process of agglomerating dispersed particles or fines into substantially spherical and crush resistant granules. The invention further relates to a method of covering a seed and binding the seed with a material mixture beneficial for seed germination. The invention also relates to an all-in-one seed agglomerated by the dual purpose binder formulation.

Description

BACKGROUND OF THE INVENTION[0001]Granulation of fertilizers and other components using binders is well known. Binders are used to adhere fertilizers and other components together into a single particle. Conventional binders do not contribute either economical or practical value to the fertilizer formulations. Thus, it is a cost ineffective component. In some cases, the use of a binder in a fertilizer composition also results in a granular fertilizer that is insufficiently hard and / or round. These granular fertilizers make encapsulation with polymers or resins difficult, resulting in inconsistent slow release fertilizers.[0002]The prior art discloses many binder systems. These binders only contribute to the agglomeration of dispersed fertilizer fines and particles. Additionally, these binders constitute a significant portion of the fertilizer composition, resulting in a fertilizer with reduced nutrient value. Due to these shortcomings, fertilizers using conventional binders result in...
