The Reasons for Selecting Cone Crushers to Crush Pebble

January 11, 2015

With the increase of the demand of artificial sand, the main sources of the machine-made sand are the sand of pebble, granite, and other materials. Because of the large amount of the storage of pebble and cobble and because the gravel made from them can meet the requirement of the sand for building in our country, the pebble sand making equipment develops a lot.

Recently, the machines used to produce pebble sand are mainly jaw crushers, impact crushers, cone crushers, and so on. However, in the mini pebble sand production line, in which about 30-300 tons pebble sand can be produced per hour, cone crushers are used a lot. According to the analysis made by the gravel project department of Fote Heavy Machinery, the reasons why most clients select cone crushers to crush pebble are as follows:

1. To reduce the wear and tear of the quick-wear parts and to prolong the service lifetime of the machine. As is known to all, the main chemical composition of pebble is , whose hardness is high. If a hammer crusher is used to crush pebble, there will be a lot of wear and tear of the hammerheads and other quick-wear parts and the output will be low. However, the cone crusher, according to the laminating crushing mechanism, is applied to crush pebble and other materials of high hardness, which can increase the crushing ratio and the output substantially, reduce the wear and tear of the quick-wear parts, and can prolong the service lifetime of the machine.

2. By using the cone crusher, the shape of the particle of the finished products is good and the quality of the gravel aggregate is high. Except for the property of crushing pebble, a cone crusher has the properties of fine crushing and coarse crushing. The shape of the particle of the finished products is good. Among the finished products, the cubic ones account for more than 90%. Besides, the particle size of the finished products is uniform.

3. By changing the types of the crushing cavity, the conversion between the coarse crushing, secondary crushing, and fine crushing can be realized. The crushing ratio of the cone crusher is high. To crush pebble, the productivity of a cone crusher is higher than that of an other crusher whose weight is the same as that of the cone crusher. Besides, the cone crusher adopts the modular design method. By changing the cavity types, the conversion between the coarse crushing, secondary crushing, and fine crushing can be realized. It can be adjusted flexibly and it has a wide range of application.

Therefore, in order to meet the requirement of the equipment in the 30-300 t/h pebble sand production line for clients, people in Fote produce PYB cone crushers, PYD cone crushers, PYZ cone crushers, hydraulic cone crushers, and the ones of different model numbers. Besides, the parts of the cone crusher can be offered to customers by Fote.
