Riding Botswana’s development wave Aggregates Business
For example, quarry management doesn’t stipulate frequency of the drill and blast processes, but the contractor has been tasked with providing an average of 65,000tonnes of rock-on-ground every month. Material is hauled from the primary crusher to Plant 2 using a 20 t Bell ADT, which is loaded by a 436 Komatsu 270 excavator. The Quarry by-products (QB), usually <1/4 in. (6 mm) in size, are the residual deposits from the production of required grades of aggregate. This paper provides findings of a detailed laboratory study with the objective of characterizing the engineering properties of QB materials produced in the primary, secondary, and tertiary aggregate production stages Frontiers Engineering Characteristics and Stabilization Performance

Primary and Secondary Crushing: Understanding the Basics
Primary crushing is the first stage of crushing that takes place at the mine or quarry. The primary crusher is the equipment that reduces the size of the materials to the size that can be processed by the secondary crusher. The primary crusher receives the materials directly from the mine or quarry, and its size reduction ratio ranges from 3:1quarry sites, there is need for regular environmental survey.

Primary Crushing 911 Metallurgist
The term “primary crusher,” by definition, might embrace any type and size of crushing machine. The term implies that at least two stages of crushing are involved, but in many cases the machine which performs the function of initial crusher is the only crusher in the plant. The factors influencing the selection of a crusher for this serviceIn a quarry setting, large rocks are extracted from the ground and then processed through a primary crusher, secondary crusher, and screens to produce the final product.
