2. Crushing Value Test of Aggreagte. What Is Crushing Value? Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load.. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.

2, Optimize the crushing circuit of the plant. In addition to the crushing cavity, optimizing the entire crushing circuit is a good overall planning method to increase production. To understand how the entire loop operates as an independent process, two points need to be judged: where the system bottleneck and the available capacity are.

The tighter the setting, the smaller the output size and the lower the throughput capacity. Jaw crushers are mainly used in primary crushing stages and are rarely used for secondary crushing. As a compression crusher, this type of machine generally produces the coarsest material because it breaks the rock along its natural lines of weakness.

Cone crushers are compression machines that take in raw materials and reduce them in size by crushing them. A variety of industries rely on these tools, such as the concrete, aggregate, mining, coal, and natural gas industries. Inside the crusher, a piece of steel, known as the mantle, rotates eccentrically.

After it was pre-crushed, the material was passed to the first crushing stage in a jaw crusher (in the case of basalt aggregate) and in conical crushers (in the case of granite and melaphyre aggregate). The initial capacity of the process systems was less than 400 Mg/h.

When the crusher is fed at the high feed rate, the measured throughput can be characterised as the capacity of the crushing operation. This capacity varied from 77.8 t/h to 194.3 t/h. The highest capacity is registered for the tests including fines in the feed material. Reducing the feed rate resulted in a 50–56% reduction of the throughput.
