Primary rock crusher

Primary crusher, referred to as coarse crusher, is widely used in mining, metallurgy, building materials, highway, railway, hydraulic, chemical and other industries. Primary crusher has the advantages of crushing ratio, uniform mechanical particle size, simple structure, simple work, inspection and maintenance, and economic operating cost. What are the primary crushing equipment? What are its advantages? Next, I will make a brief analysis (for reference only).

Difference between primary and secondary crusher

There are many kinds of crusher, some are used for rough breaking and some are used for fine breaking, different kinds of crusher action and performance are also different, the following is a simple analysis of their respective characteristics.
Fine breaking is a type of jaw crusher. Usually as a secondary crushing instead of the impact crusher, the E type fine crusher referred to as fine breaking is the most commonly used crushing equipment in the crushing series, mainly used for the compressive strength of not more than 320 mpa of various materials, with reliable, easy maintenance, economic operating costs and other characteristics.
Coarse crusher: also known as coarse crusher, coarse crusher is widely used in mining, smelting, building materials, road and railway, water conservancy and chemical industry and many other sectors, crushing compressive strength does not exceed 320 mpa of various materials.
Heavy hammer breaking, that is, heavy hammer crusher, alias is also called hammer king. Suitable for mining, cement, coal, metallurgy heavy hammer breaking: building materials, highways, burning and other departments of medium hardness and brittle materials for fine crushing. The difference between the heavy hammer crusher and the hammer crusher: the hammer head of the heavy hammer can be rotated 360 degrees around the hammer shaft, and the length of the hammer head is not the same, and the material of the hammer head is not the same.
The coarse crusher (coarse break) is placed in the first break, the fine crusher (fine break) is placed in the second break, the coarse crusher feed port is larger than the fine break, and the working efficiency and life are similar, because the working principle is the same. Are the use of low speed, high stability of the working principle.
Ultrafine mill is a fine powder and ultrafine powder grinding processing equipment, this equipment is mainly suitable for medium and low hardness, humidity is less than 6%, Mohs hardness below 9 non-flammable and explosive non-metallic materials.
