INTRODUCTION. This unit deals with the concept of 'Aggregate Planning', which is an operational activity which does an aggregate plan for the production process, in advance of 3 to 18 months, to give an idea to management as to what quantity of materials and other resources are to be procured and when, so that the total cost of operations of the organisation is kept to the minimum over ...

Aggregate planning: General plan – Combined products = aggregate product » Short and long sleeve shirts = shirt Single product – Pooled capacities = aggregated capacity » Dedicated machine and general machine = machine Single capacity – Time periods = time buckets » Consider all the demand and production of a given month together

There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties.

Step 2 Based on the aggregate plan, determine the aggregate production rate. If you use the level plan with inventories and back orders, the aggregate production rate is set equal to average demand. In addition, if you allow no back orders, the size of the workforce is …

The process flow can be defined as a combination of several machines and several techniques that are used together to produce the required products. The process flow is one of the most important parts in defining how your new aggregate plant is going to operate to make the required products as economically as possible.

Aggregate Processing Plant Design. Aggregate processing plants include feeding system, crushing sand system, screening system and sorting system. The selection of aggregate processing plant is an important part of modern aggregate production. Studies have shown that gravel aggregate has become the second largest consumable for human beings.

However, the aggregate resources needed for the construction and maintenance of highways, local roads, and streets, as well as for basic materials for concrete structures and drainage applications, often are not given sufficient consideration early in the planning and design process.

Figure 11.1-1 shows the batch mix HMA production process. Raw aggregate normally is stockpiled near the production unit. The bulk aggregate moisture content typically stabilizes between 3 to 5 percent by weight. Processing begins as the aggregate is hauled from the storage piles and is placed in the appropriate hoppers of the cold feed unit.
