Basalt Jaw Crusher
Processing material: basalt
Production capacity: 5000 / d
Introduction to Basalt Jaw Crusher

Basalt is a kind of basic extruded rock. The mineral composition is mainly composed of basic feldspar and pyroxene. The rocks are dark in color, generally black, sometimes grayish green and dark purple. It has a patchy structure. It is brittle, so it is not easy to mine large stones. The main components of basalt are silicon dioxide, aluminum oxide, iron oxide, calcium oxide, magnesium oxide (and a small amount of potassium oxide and sodium oxide), and the content of silicon dioxide most. Basalt has a wide range of uses. For example, basalt is the best material for repairing roads, railways, and airport runways. It has strong compression resistance, low crushing value, strong corrosion resistance, and asphalt adhesion. It has the advantages of abrasion resistance, low draft, poor electrical conductivity, strong compression resistance, low crushing value, strong corrosion resistance, and asphalt adhesion. It is recognized internationally and is the best cornerstone for the development of railway and road transportation.

Basalt processing technology
Because basalt has strong hardness and rich silicon content, the operation of the crushing production line is mainly divided into three stages, namely coarse crushing, fine crushing and screening.

The specific process: the vibrating feeder will evenly send the basalt rock into the jaw crusher for coarse crushing. The coarsely crushed basalt is transported by a conveyor to a cone crusher for fine crushing, and the finely crushed basalt is processed by a vibrating screen. After screening, the basalt sand is the finished sand we want to get.

Production advantage
1. Larger crushing ratio, better output
2. Good grain shape
3. Simple structure, easy to maintain
