• For autogenous mill sizing. The DWT is used with JKTech autogenous mill modelling to size the autogenous mill(s) when designing a grinding circuit. ARMC generally recommends that, in these cases, the power-based design grindability tests (work index tests) are performed in conjunction with the DWT, to limit the risk in mill selection.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Autogenous mill, pebbles, ore sorting INTRODUCTION A well known natural phenomenon in autogenous (AG) mills is the build-up of pebbles. These pebbles are typically called "critical size material" and occupy a large volume of the mill and thus reduce the capacity for new material to be processed. In addition to the mill volume reduction, the ...

In autogenous mills the diameter is greater than the length. They can be as much as 40+ feet in diameter. Patented in 1959, AG Mills are not so popular any more. This large diameter of mill is required to achieve the impact necessary to grind the ore. The main source of reduction comes from the impact of the rock falling on rock.

Autogenous grinding work is conducted in a separate pilot setup. The crude ore is crushed to a maximum size of 9 in. and screened into 3 sizes. The primary mill is 5-½ ft. in diameter. The length can be varied from 2 ft. to 5 ft. in 4 and/or 11 in. increments. The secondary grinding circuit uses a 3 ft. diameter by 5 ft. long pebble or ball mill.
