A Comparison of Three Types of Coal Pulverizers

This section further reduces the coal size by attrition and by impact of coal on the moving and stationary parts. There is no metal-to-metal contact of pulverizing elements. Oversized particles do not pass the rejector and remain in the pulverizing section for further size reduction. Properly sized pulverized coal, however, passes into the fan section. In this section, an integral fan wheel ...

Coal Mine - an overview ScienceDirect Topics

The four types of equipment for size reduction of run-of-mine coal ([2] and [3]) are described as follows: 1. The rotary breaker causes the coal to break by lifting it to a given height and dropping it against a hard surface. It is a cylindrical unit (operating at low speed) that subjects the coal particles on the liner to undergo centrifugal motion; the liners of the rotary breakers are ...

Coal Sample Preparation Procedures Overview

02/07/2018  Coal sample reduction is the process of reducing the size of coal samples, aiming at increasing the number of sample particles and decreasing the sample division bias. Samples which have the same quality, the size is smaller and the number is larger, the bias of sample division will be lesser. However, crushing consumes time and energy, especially lead to water loss. Therefore, a mess of

Mineral processing - Wikipedia

In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition. Compression and impact forces are extensively used in crushing operations while attrition is the dominant force in grinding. The primarily used equipment in crushing are jaw crushers, gyratory crushers and cone crushers whereas rod mills and ball mills, usually closed circuited ...
