CALCULOS DE INGENIERIA DEL CIRCUITO DE CHANCADO

INTRODUCCION

El Chancado o conminucin es un proceso de reduccin de tamao de rocas grandes a fragmentos de 1/4 a 3/8 usando fuerzas de compresin y menor proporcin fuerzas de flexin, friccin, cizallamiento y otras.

Las operaciones de chancado se realiza en maquinas que se mueven a velocidades relativamente medias o bajas, y las cuales consumen una cantidad considerable de energa en la produccin de calor y sonido, por lo que se consideraba que su eficiencia era muy baja con respecto a la eficiencia obtenida en molienda, sin embargo, se encontr que esta tendencia era lo contrario, es decir que la trituracin poda ser mas eficiente que la molienda, al observar que le ambiente de fragmentacin era fundamental en la produccin de finos.

Durante la trituracin el ambiente de fragmentacin es el aire, mientras que en la molienda es el agua, el cual evita las fracturas secundarias al rebotar las fracciones de la partcula fracturada en la cavidad de fragmentacin, obtenindose de esta manera menor cantidad de finos. De lo anterior se desprende que la trituracin tiene una importancia mayor de la que se asigno hasta hace unos aos.

Como se puede apreciar en el cuadro de resumen del consumo de energa Kw-hr/TM se observa que aunque las chancadoras tienen el mismo tonelaje horario. Esta diferencia es principalmente por la razn de reduccin (Rr), que para el caso que estamos observando como la razn entre las aberturas de los tamices, por los cuales pasaran el 80% del material de alimentacin y el 80% del producto de la conminucin, mas no la razn del tamao mximo de la partcula en la alimentacin y el tamao mximo de la partcula que deja la chancadora. Un factor importante es la distribucin granulometrica.

En cuanto al rendimiento se puede deducir que fuera de un tamao especifico como objetivo, es mejor obtener un alto rendimiento en funcin a una mayor razn de reduccin, un alto rendimiento en funcin al tonelaje tratado. Pese a que esta dos variables deben ser manejadas con criterio dependiendo de las condiciones de operacin. Ya que la forma ms efectiva de mejorar el rendimiento es mantener la ms alta potencia instalada en las chancadoras.

DETERMINACION DE LA POTENCIA REQUERIDA DE CADA UNA DE LAS FAJAS

El objetivo principal de los clculos es verificar que cada faja este operando con la potencia del motor adecuado.

En una faja transportadora se puede considerar tres potencias:

POTENCIA HORIZONTAL.- Es la potencia requerida para mover la faja cargada entre dos puntos horizontales y est dado por la siguiente:

HPH = Factor C * La * STPH

Donde:

Factor C = Es una variable desarrollada empricamente y se encuentra en tablas de la CEMA, este factor incluye el peso de todas las partes en movimiento por pie de largo de la faja transportadora.

La = Es la distancia ajustada entre los centros de las poleas y se calcula:

La = 0.821 * L * 139.45

Donde:

L = la distancia original entre los centros de las poleas en ft.

POTENCIA VERTICAL.- Es la potencia requerida para alzar o bajar la faja cargada y solo se emplea en los clculos de las fajas inclinadas, y la forma es.

HPV = STPH * H

990

Donde :

H = altura o elevacin de la faja en pies.

POTENCIA DEL TRIPER.- Es la potencia requerida para operar el mecanismo de descarga llamado tripper, se considera slo si la faja es provista del tripper, esta dado por la ecuacin.

HPT = Factor A * fpm * STPH * h

990

Donde: Factor A = E es un factor basado en las resistencias friccional

de las poleas del Tripper

Fpm = Velocidad de la faja en pies/minuto

h = Altura del tripper

Para una faja inclinada, la potencia total est determinada por:

HPtotal = HPH + HPV

ANALISIS GRANULOMETRICO Y REPRESENTACION DE DISTRIBUCION DE TAMAO

Las operaciones de conminucin dependen en un alto grado del tamao o distribucin de tamaos de las partculas que intervienen en estas operaciones.

La forma ms usual de determinar los tamaos de un conjunto de partculas es mediante el anlisis granulometrico de una serie de tamices. Muchas funciones de distribucin de tamao han sido desarrolladas para su aplicacin en procesamiento de minerales, pero se usan en forma generalizada las de Gates - Gaudin Schuhmann (GGS) y la de Rosin Rammler.

La funcin GGS es la que ms se usa en circuitos de chancado, es por eso que solo aplicaremos esa funcin.

APLICACIN EN LA DISTRIBUCION DE TAMAO DE GGS EN LAS ZARANDAS SECUNDARIAS Y TERCIARIAS EN EL CIRCUITO DE CHANCADO

A continuacin se observa las distribuciones granulomtricas para el anlisis y determinacin de la performace del circuito de chancado en las operaciones de chancado y clasificacin:

xo = tamao mximo de partcula en la distribucin, micras.

X = tamao de partcula en la distribucin, micras.

Para linealizar la ecuacin se toma en logaritmo:

Log F(x) = log (x)a - log 100

(X0)a

Y = m. X + B ec (B)

Donde:

log F(x) = Y

a = m (pendiente de la recta)

log 100 = B

(X0)a

log x = X

Basados en la teora de ajuste de curvas por el mtodo de mnimos cuadrados hallamos los valores de m y B en la ecuacin (B)

m = N -

N - (x)2

m = 0.450594

B =

N B = -0.30574

r = N

[ (N

EMBED Equation.3 ] 0.5

r = 0.99839

Luego: m = a = 0.450594

Log (100/(X0) 0.4505) = -0.30574

Despejando X0 tenemos

Log X0 = 5.117111 X0 = 130951

Finalmente la ecuacin de distribucin granulomtrica GGS ser:

F (x) = 100 x 0.4505

130951

Reemplazando valores obtenemos los F (x) calculado.

Se observa que no existe gran variacin entre los valores reales y los calculados, por lo que se puede observar que la distribucin de GGS se ajusta perfectamente, adems en el mtodo grfico la partcula que sale de la chancadora es de 130900 micras, por lo que geomtricamente la recta representa la funcin de distribucin granulometrica.

Como se observa comparando las curvas experimentales con las de los productos de las chancadoras la distribucin GGS presenta preferentemente los puntos experimentales correspondientes a casi todas las mallas con cierta variacin en los tamaos gruesos.

La correlacin para estas curvas tiene un coeficiente bastante prximo a 1 como lo muestran los valores calculados de F(x) los cuales coinciden con los valores observados experimentalmente.

Es importante resaltar que la distribucin GGS no puede representar satisfactoriamente los puntos experimentales en todos los rangos como se puede apreciar en la distribucin granulometrica de la alimentacin de las zarandas terciarias; porque precisamente este es un punto critico, porque es donde se mezcla el recirculante del terciario con la alimentacin fresca del overzise del circuito secundario; por lo tanto no se da una mezcla homognea al caer en las tolvas de alimentacin, este inconveniente se refleja en la eficiencia de las zarandas y chancadoras terciarias.

ANALISIS DE LA CURVA DE PARTICION DE LAS ZARANDAS TERCIARIAS

El clasificador debe separar una mezcla original de partculas en dos partes, una de partculas gruesa de mayor tamao a un valor llamado D50, y otra mas fina menor al D50, el D50 es el tamao de partcula que tiene la misma probabilidad de ir con los grueso (overzise) o a los finos (underzise) el cual se le denomina como corte de clasificacin.

Es necesario precisar que la curva de particin slo es posible calcular en un circuito cerrado de chancado o molienda, es por lo que se calculara la curva de particin de las zarandas terciarias, las cuales operan en circuito cerrado.

DETERMINACION DE LA EFICIENCIA OPERATIVA DE LA ZARANDA

SECUNDARIA Y TERCIARIA

Es muy importante la evaluacin de estos equipos para saber en que medida se esta efectuando la clasificacin granulometrica del mineral, cual es la eficiencia, tonelaje de rechazo y tamizado. Tambin se verifica si la zaranda esta operando apropiadamente para el tonelaje tratado.

DEDUCCION DE LA FORMULA PARA EL CALCULO DE LA EFICIENCIA

Aplicando balance de materia

F = O + U ec.(1)

Donde :

F : Tonelaje de mineral fresco alimentado

U : tonelaje de mineral tamizado

O : Tonelaje de mineral rechazado

Por balance de tamaos de partculas

Ff = Oo + Uu ec.(2)

Donde f, u, o, son los porcentajes pasantes de partculas en los tres flujos

Por definicin la eficiencia:

Uu

E = x 100 ec.(3)

Ff

De (1) : O = F - U

Reemplazando en la ec.(2)

Ff = (F -U)o + Uu

Ff = Fo - Uo +Uu

F( f o ) = U (u o)

U/F = (f - o) / (u -o)

Reemplazando en la ec.(3)

(f - o) u

E = x 100 ec.(4)

(u - o) f

Donde:

f: Porcentaje de partculas finas inferiores que d en la alimentacin

u : Porcentaje de partculas finas inferiores que d en underzise.

o: Porcentaje de partculas finas inferiores que d en overzise.

d: Abertura de la malla en la zaranda.

La relacin deducida para el calculo de la eficiencia de la zaranda. Expresa la relacin entre el peso del mineral tamizado y el peso total que realmente existe en el mineral, que debi haber sido tamizado en la carga alimentada.

Es importante sealar que la eficiencia calculada de las zarandas son aparentemente altas, pero esta operacin de clasificacin intervienen aun mas variables tales como, caractersticas del mineral , % de humedad del mineral, distribucin granulometrica, tiempo de residencia de la partcula, inclinacin , vibraciones, balance de la zaranda, pero si duda una de las mas importante es la relacin capacidad vs eficiencia, que es una relacin inversa, la cual es manejada con la altura de la cama, por esto que la eficiencia del piso inferior es mas alta que la del superior, ya que este ultimo cumple dos funciones, la de realizar una pre clasificacin y proteger el piso inferior.

Es importante sealar que con un gran porcentaje de tamao de partcula entre 0.75 y 1.25 del tamao de abertura del tamiz la eficiencia cae notablemente. Tambien se puede sugerir que se puede optimizar en cuanto a capacidad principalmente las zaranda banana en funcin a la distribucin granulometrica.
