Primary Impact Crushers are preferred for their high capacity and reduction ratios in crushing soft and medium hard rocks like limestone, gypsum. Due to their operating principle, reduction ratio is higher than in jaw crushers. Maximum feed size (mm) Maximum feed size (inch) 600 24: 600 24: 900 36: 1000 40: 1300 52: Maximum Speed (RPM

Of these three types, the Standard and Non-Clog Hammermill types are considered primary crushers due to the fact that they can accept large feed

The degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced. Primary crushing is the first stage of material reduction and can sometimes be the only stage needed

Jaw crushers are sized based upon the dimensions of the top feed inlet (gape) or the dimensions of the jaws. For example, a 32 x 54 sized jaw crusher will

This angle depends on the size, hardness and frangibility of the material. It cannot be selected as too large or too small. The nip angle in primary crushers is lower than in secondary crushers. Generally, this value is between 18 and 24 degrees in primary jaw crushers, and between 22 and 28 degrees in secondary crushers.

Primary coal crusher: Used for larger coal size. The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is

10/8 · The first step in selecting a primary crusher is to proceed at a high level. It is necessary to define the intended use of the crusher. This purpose is a given prior to the entire decision-making process. Sometimes a degree of guidance or experience is required. The two main factors to consider when determining the purpose are the feed size and

3/4 · There are two major categories of processing. One is comminution and the other one is separation. The process "Comminution" involves size reduction and size-wise classification called as screening
