Counter-type sand making machine is a new type of high-efficiency crushing equipment
When the counter-type sand making machine is working, the rotor rotates at a high speed under the driving of the motor. When the material enters the action area of the hammer, it collides with the hammer on the rotor, and then is thrown to the counter-attack device to break again, and then counterattacks. The lining rebounds back to the hammer action zone and re-crushes. This process is repeated, the material enters from large to small, and the counter-attack cavity is repeatedly crushed until the material is broken to the required particle size and discharged from the discharge port.
The counter-type sand making machine has the advantages of small volume, simple structure, large crushing ratio (up to 40), low energy consumption, large production capacity, uniform product size and selective crushing effect. Simple and reasonable structure, self-shocking, ultra-low cost; unique bearing installation and advanced spindle design make the machine have heavy load and high speed rotation. It has the functions of fine crushing and coarse grinding; high reliability and strict safety guarantee device to ensure equipment and personal safety; stable operation, low working noise, high efficiency and energy saving, high crushing efficiency; small influence on moisture content of materials, water content up to 8 % or so; wear parts are low in loss, all wearing parts are made of high quality wear-resistant materials at home and abroad, and have a long service life. A small amount of wear-resistant parts are made of special hard and wear-resistant materials, which are small in size, light in weight and easy to replace. The airflow inside the vortex chamber is self-circulating, and the dust pollution is small. The material self-lining in the impeller and the vortex crushing chamber greatly reduces the wear parts cost and maintenance workload. During the production process, the stone material can form a protective bottom layer, and the body is wear-free and durable. Various installation methods, removable installation. The product is cubic, with high bulk density and low iron pollution. Can be used as a stone shaping machine.
The disadvantage of the counter-type Silica Sand Crusher is that the hammer and the counter-attack are particularly prone to wear, especially the hard ore that is broken, and the wear is more serious and needs to be replaced frequently. Currently, due to the appearance of some wear-resistant materials, it has been applied in some metal concentrators.
The counter-type sand-making machine is divided into a single-rotor counter-attack sand-making machine, a double-rotor counter-attack sand-making machine, a single-stage hammer-type counter-attack sand-making machine and a composite plastic counter-attack. The counter-attack sand-making machine (counter-breaking) can handle the granularity. Various coarse, medium and fine materials ores, rocks (granite, limestone, concrete, etc.) with a compressive strength of not more than 320 MPa, widely used in hydropower, highways, artificial sand and gravel, crushing and other industries. . This series of impact crushing structure is unique, equipped with high-chrome plate hammer and unique counter-attack lining; suitable for hard rock crushing, high efficiency and energy saving; adjustable grain size can simplify the crushing process, and has large crushing ratio and high crushing efficiency. The shape of the product is cubic, and it can be selectively broken.
