The Role Of Reversible Hammer Crusher In Small And Medium Sized QuarriesLast Update:2020-05-12 19:57:06
With the continuous construction and development of high-speed railway, expressway, bridge and hydropower station in China, the demand of stone and sand for infrastructure construction is also increasing, which also greatly promotes the development of quarry industry. At present, there are many small and medium-sized quarries in China, most of which are hillside quarries, with an annual production scale of 30000-50000 tons. These small and medium-sized quarries also face many problems to be solved. For example, due to the small mining boundary permitted by the mining right, the original slope of the topography and landform of the stope is relatively steep, and the natural conditions of multi-step mining in small open-pit quarry are insufficient, so it is difficult to promote. In recent years, reversible hammer crusher has played an irreplaceable role in small and medium-sized quarries.
In order to develop small and medium-sized quarries, it is necessary for professional personnel to visit the site, customize a reasonable plan according to the actual situation, and equip with equipment with reasonable price, high efficiency and stability. The main equipment of the quarry is divided into feeding equipment, crushing and screening equipment, sand making and washing system, logistics transmission equipment, etc. among them, the feeder and vibrating screen are generally general auxiliary equipment, most of the materials can be produced with similar equipment. The crushing equipment is different. According to the characteristics of materials, various kinds of crushing equipment will be used in the gravel production line of quarry. Investors should carefully select crushing equipment after careful analysis and field investigation according to the actual situation. It has been proved by practice that the reversible hammer crusher is more suitable for small and medium-sized quarries than other crushing equipment with high price, high energy consumption and slow investment income.
The rotor of reversible hammer crusher is reversible, which is generally used for fine crushing in the crushing production process of quarry. It is mainly used to crush materials by impact. Materials enter the crusher and are crushed by the impact of the high-speed rotating hammer head. The crushed materials obtain kinetic energy from the hammer head and rush to the baffle plate and screen bar in the frame at high speed. At the same time, the materials collide with each other and are broken many times. The materials smaller than the gap between the screen bars are discharged from the gap, and some larger materials, The screen bar is again impacted, grinded, extruded and broken by the hammer head, and the material is extruded from the gap by the hammer head, so as to obtain the product with the required particle size. For other details, please refer to the picture of reversible hammer crusher.
Small and medium-sized quarries are widely distributed in all villages and towns across the country. Hammer crusher is popular in small and medium-sized quarries because of its small investment, large crushing ratio, high production capacity, uniform product size and stable operation. In the process of using hammer crusher, the key part is the hammer head. Therefore, in normal operation, we only need to strengthen the maintenance and repair of the hammer head, and solve the problems as soon as possible. It can ensure the stable operation of crushing in the quarry.
After long-term technical research and international exchanges, the quality and technical content of Caesar's products have reached the first-class level in the world, and have been widely recognized and praised in the international market; the products are exported to more than 160 countries, such as the United States, Russia, etcGet Price Now
