Primary, secondary, and tertiary crushing are three stages in the comminution process that break down large rocks into smaller pieces of varying sizes. Each stage uses different types of crushers and has distinct advantages and disadvantages. This article provides a comprehensive guide to primary, secondary, and tertiary crushing.

For example, if a company can sell 500,000 tonnes per year, its crushers need to produce just short of 42,000 tonnes each month. If the crusher is set up to run three days a week (about 13 days a month) for eight hours a day, the operation will require a machine capable of processing 400 tph. {{image3-A:L-w:350}}

For a hypothetical plant with a baghouse and stack flow of 4,000 SCFM, the emission rate would be 4,000 SCFM * 0.022 gr/DSCF * 60 min/hr / 7,000 gr/lb = 0.75 lb/hr. If this plant operates up to 1,200 hours per year, annual emissions are 0.75 lb/hr * 1,200 hours/year / 2,000 lb/ton = 0.45 TPY from the stack in question.

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.

The cost of labor and materials affects batching plant construction prices by driving up the total project expenses in terms of wages, material purchases, and miscellaneous items such as tools and supplies. These added costs could potentially add a significant expense to batching plants constructed in the Philippines.

Crushing plants operate under unforgiving conditions and in most cases involve very abrasive materials. Multiple factors, therefore, influence the performance of crushers [ 3 ]. On the one hand, the size decrease in breakable materials is one of the most vital mechanical processes within raw material processing operations.

In summary, setting up a crushing plant involves site selection, equipment procurement, process design, safety specifications, and effective operations and maintenance.Proper planning and management are crucial for efficient plant operation.
