Abstract

The present patent is a special model of a screen module of blade type used in ore-grading, which has high impact strength, is robust and withstands abrasion caused by the materials screened, and it is composed of a rectangular shell (1) with lateral recess (2) at the ends, for fixing to the structure of the screen, having parallel bars (3) of "blade" type made from special polyurethane-coated tempered steel and arranged longitudinally, regularly spaced from one another.

Description

"DISPOSIÇÃO INTRODUZIDA EM GRELHA DO TIPO FACA PARA PENEIRAS "GRIDDENING ARRANGEMENT OF THE TYPE KNIFE

CLASSIFICADORAS DE MINÉRIOS" ORE CLASSIFIERS "

1) Refere-se a presente patente, que diz respeito à indústria siderúrgica e de mineração, a um modelo especial de módulo de peneira do tipo faca utilizada na classificação de minérios, que oferece grande resistência ao impacto, dureza e resistência à abrasão dos materiais peneirados.  1) This patent, which concerns the steel and mining industry, refers to a special model of knife-type sieve module used in ore classification, which offers high impact strength, hardness and abrasion resistance of materials. sifted.

2) A peneira um utensílio que serve para deixar passar as substâncias reduzidas a pequenos fragmentos e principalmente utilizado para separação e classificação de materiais constitui uma parte fundamental em pedreiras ou na mineração e a escolha da peneira ideal exerce efeito crítico na qualidade do produto final em função da manutenção e montagem dado a abrasão dos materiais peneirados.  2) The sieve is a utensil that allows to pass the reduced substances to small fragments and mainly used for separation and classification of materials. It is a fundamental part in quarries or mining and the choice of the ideal sieve has a critical effect on the quality of the final product. maintenance and assembly function given the abrasion of the sieved materials.

3) Produzidas geralmente a partir de uma tela do aço ainda podem ser encontradas no atual estado da técnica com materiais plásticos tais como o poliuretano, através da junção da carcaça e elementos, por partes do tipo modular e fixadas em perfis metálicos, sendo práticas mas de manutenção constante dado ao elevado volume de desgaste em operação.  3) Produced generally from a steel mesh can still be found in the present state of the art with plastic materials such as polyurethane, by joining the housing and elements, by modular type parts and fixed in metal profiles, being practical but constant maintenance due to the high volume of wear in operation.

4) A presente neste sentido, inova apresentando um modelo de peneira modular desenvolvida com a estrutura base são em aço carbono especialmente tratado e as laterais são em aço revestidas com poliuretano, tornando a grelha um produto com diferencial de estratificação superior aos convencionais.  4) In this sense, innovates by presenting a modular sieve model developed with the base structure are made of specially treated carbon steel and the sides are made of polyurethane coated steel, making the grid a product with a higher layering differential than conventional ones.

5) Desta forma a separação (produtividade) dos materiais é aumentada consideravelmente porque, quando o material passa sobre as barras temperadas (em aço especial) fazendo com que as partículas menores passem rapidamente e as maiores são distribuídos ao longo da superfície da grelhas (plana, sem vales ou degraus) sendo quebrados ao longo do percurso na peneira. Seu sistema modular adapta-se a qualquer tipo de peneira objetivando uma ótima relação custo benefício porque oferecem: grelhas destinadas ao produto final via seca ou via úmida; classificações precisas e aumento na velocidade de aceleração e queda das partículas; maior vida útil com menor desgaste; aumento da produtividade com menor tempo na interrupção do processo podutivo e maior tempo entre trocas; produção sob medidas para adequação em qualquer dimensão para aplicação em mineração, pedreiras e usinas siderúrgicas; ampla gama de espessura para manusear materiais; diminuição do volume de "PU" descartados na natureza; economia de recursos pelo aumento do ciclo de reciclagem de materiais empregados; sistema modular que se adapta a qualquer tipo de peneira vibratória existente. 5) In this way the separation (productivity) of the materials is considerably increased because when the material passes over the tempered bars (in special steel) making the smaller particles pass quickly and the larger ones are distributed along the grate surface (flat, no valleys or steps) being broken along the sieve path. Its modular system adapts to any type of sieve for a great cost-benefit ratio because it offers: dry or wet grids for the final product; accurate classifications and increased acceleration and falling velocities of particles; longer service life with less wear; increased productivity with less time to stop the poductive process and longer time between changes; tailor-made production to suit any size for application in mining, quarrying and steel mills; wide range of thickness for material handling; decreased volume of "PU" discarded in nature; resource savings by increasing the recycling cycle of materials employed; modular system that fits any type of existing vibrating screen.

Figuras estas, que não restringe sua configuração quanto às suas dimensões, proporções e eventuais tipos de acabamentos inseridos e nem o alcance de sua aplicação prática.  6) The intruduced knife-type grid arrangement for ore-classifying sieves, object of this utility model patent, can be better understood by referring to the accompanying figures, which are part of this descriptive report and contain numerical references together with the description of its technical peculiarities. These figures, which do not restrict their configuration as to their dimensions, proportions and any types of finishes inserted or the scope of their practical application.

7) A figura 1 é uma vista em perspectiva do modelo.  7) Figure 1 is a perspective view of the model.

8) A figura 2 é uma vista frontal do mesmo, mostrando as "facas" da grelha.  8) Figure 2 is a front view thereof showing the "knives" of the grid.

9) A figura 3 é uma vista lateral.  9) Figure 3 is a side view.

10) De acordo com esta figura e suas referências numéricas o objeto desta patente refere-se a um modelo de módulo de grelha do tipo "faca" para peneiras classificadoras de minérios composto de carcaça (1) retangular com encaixe lateral (2) nas extremidades para fixação na estrutura cilíndrica do suporte da peneira, adaptando-se a qualquer tipo de peneira. 10) According to this figure and its numerical references the object of this patent relates to a grid module model of the type "Knife" for ore grading sieves composed of rectangular housing (1) with side engagement (2) at the ends for attachment to the cylindrical structure of the sieve holder to suit any type of sieve.
