Lazy loading don't find the declaration of my component

I'm trying to apply lazy loading in my app routing module, but when i exclude the "Dashboard Module" from app.module.ts, my component "DialogConfirmacaoExclusao" is alerted that is not part of any ngModule.

I try:

My app routing module:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

const appRoutes: Routes = [
  {path: 'dash', loadChildren: 'src/app/components/dashboard/dashboard.module#DashboardModule'}
];

@NgModule({
  imports:[RouterModule.forChild(appRoutes)],
  exports: [RouterModule]
})
export class AppRoutingModule{}

In my app.module i import my appRoutingModule e exclude the DashboardModule from the list of imports:

import { AppRoutingModule } from './app.routing.module';

My dashboard routing module:

const dashboardRoutes: Routes = [
    {path: 'dash', component: DashboardComponent, canActivate: [AuthGuard],
    children: [
    { path: '', component: BemvindoComponent, pathMatch: 'full' },
    { path: 'home', component: BemvindoComponent, pathMatch: 'full' },
    { path: 'custofixo', component: CustofixoComponent, pathMatch: 'full' },
    { path: 'custoextra', component: CustoextraComponent, pathMatch: 'full'},
    { path: 'custovariavel', component: CustovariavelComponent, pathMatch: 'full'},
    { path: 'listagemcustofixo', component: CustoMensalFixo, pathMatch: 'full'},
    { path: 'operador', component: OperadorComponent, pathMatch: 'full', canActivate: [CadOperadorGuard]},
    { path: 'produtos', component: ProdutoComponent, pathMatch: 'full'},
    { path: 'tipoprodutos', component: TipoprodutoComponent, pathMatch: 'full'},
    { path: 'meuperfil', component: MeuperfilComponent, pathMatch: 'full'},
    { path: 'confestoque', component: ConfEstoqueComponent, pathMatch: 'full'},
    { path: 'confprecificacao', component: ConfPrecificacao, pathMatch: 'full'},
    { path: 'monitoramento', component: MonitoramentoComponent, pathMatch: 'full'},
    { path: 'listagemcustovariavel', component: CustoMensalVariavel, pathMatch: 'full'},
    { path: 'listagemcustoextra', component: CustoExtraMensal, pathMatch: 'full'},
    { path: 'produtoscalculados', component: ProdutosCalculadosComponent, pathMatch: 'full'},
  ]}
];

@NgModule({
    imports: [RouterModule.forRoot(dashboardRoutes)],
    exports: [RouterModule]
})

export class DashboardAppRouting {}

My dashboard module declare and export the component "DialogConfirmacaoExclusao":

import { DialogConfirmacaoExclusao } from '../dialogexclusao/dialog-exclusao.component';
  exports:[
    DialogConfirmacaoExclusao
]

...

  declarations: [DialogConfirmacaoExclusao]

But i receive:

Uncaught Error: Component DialogConfirmacaoExclusao is not part of any NgModule or the module has not been imported into your module.

export class AppModule { }

@Edit:

i imported, declared and exported the DialogConfirmacaoExclusao in app.module but now i receive: "dashboard component is not part of any ngmodule..." but don't make sense but if i declare in app module i lose the perform from my lazy loading, right?
