300tph Coal grinding process Introduction

The process of grinding coal into a desired particle size is an important stage in coal production. Coal mining equipment manufacturers typically design their grinders with the intention of providing a product that can be used in various industries, including power generation, steel production, and cement manufacturing. However, the end user—in this case, the coal-fired power plant or steel mill—may have different requirements for particle size, distribution, and other physical properties.

As a result, customizing a grinder to specific application needs is often necessary. This blog will provide an overview of the considerations and equipment involved in designing a customized coal grinding hammer mill will circuit for a 2 tph (tonnes per hour) production line.

The first step in any grinding circuit design is to determine the desired finished product size and distribution. For example, in a power plant application the coal might need to be ground to 80% passing 200 mesh (75 microns), but for a blast furnace application particle sizes as large as 3 inches (76 mm) might be required. The selection of the appropriate grind size is heavily dependent on the type ofcoal being processed; for instance, lignite coalis typically easier to grind than anthracite coal.

Once the desired finished product size is determined, the next step is to select the appropriate piece of equipment to do the job. In most cases, a ball mill is usedto performthegrinding; however, there are also rod mills, autogenous / semi
