(4) Dry production method: The main process of artificial sand dry production is that aggregate after crushing and sand making process, is directly sent to the vibrating screen, where the mixture larger than 5mm is screened out, and the sand smaller than 5mm is directly transported into the finished sand bin through the belt conveyor, which can reduce the loss of stone powder.

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

Dry production means that the process of the entire production line is basically free of water. This dry type aggregate production process is mainly adopted in northern China. Semi-dry production means that there is no water in the section before crushing and before crushing, have high cleanliness. Semi-dry production processes are used more in southern China.

They must be dry and clean before they can be used. Aggregates are only as good as their processing. They are mined, crushed, washed, and separated.

The aggregate planning process takes this thought into consideration and allows for contingency measures. These are put in place so that the manufacturing facilities can accommodate the changes that occur in production as well as orders from the customers.

The method is based on comparing the porosity of a particular dry aggregate fraction before kneading to the porosity of said fraction after kneading. The porosity before and after kneading is defined by the ratio between the bulk density and the apparent density. The method has proved useful and it helped reveal some characteristics on the process of kneading.
