Introduction of gneiss mineral composition, what are the advantages of gneiss crushing equipment?
Gneiss is a metamorphic rock with clear bands, its grains are relatively coarse, and some contain a lot of quartz and feldspar. Gneiss is widely distributed, it can be used as crushed stone, and it is often used for paving. A new type of gneiss rock crushing equipment produced and developed by SMMVIK works very well, and hereby makes a detailed introduction for our customers.
Gneiss Mineral Composition:
Gneiss is a metamorphic rock. Usually a medium to high spoilage product. With obvious gneiss-like structure. It is mainly composed of feldspar, quartz and various dark minerals (mica, amphibole, pyroxene, etc.). According to the material composition of the rock, it can be divided into aluminum-rich gneiss, plagioclase gneiss, alkali long (binary) gneiss and calcareous gneiss.
Gneiss rock crushing equipment
The gneiss European stone crushing equipment produced by SMMVIK is the HJ jaw crusher. The products produced by the HJ jaw crusher are excellent in particle shape, in the form of cubes, with low needle flake content, suitable for aggregate shaping and artificial sand making. And high highway aggregate production.
What are the advantages of gneiss crushing equipment?
1. HJ jaw crusher has high efficiency and has the functions of fine crushing and coarse grinding;
2. HJ jaw crusher has large feeding particle size, large crushing ratio and high output;
3. HJ jaw crusher has the advantages of large crushing ratio, uniform product particle size, simple structure, reliable function, simple repair and economical operating costs;
The principle of gneiss crushing equipment:
HJ series jaw crusher adopts the bending kneading type. The motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw of jaw crusher rises, the included angle between the elbow plate and the movable jaw becomes larger, and then the movable jaw plate is pushed close to the fixed jaw plate. At the same time, the materials are kneaded, rubbed and crushed; When the jaw crusher moves downward, the included angle between the elbow plate and the movable jaw becomes smaller, and the jaw crusher movable jaw plate disengages from the fixed jaw plate under the action of the pull rod and spring. At this moment, the crushed materials are discharged from the lower opening of the jaw crusher crushing chamber, and the crusher movable jaw is rotated with the motor to crush and discharge materials periodically to achieve mass production.
