The main component of limestone is calcium carbonate, which is widely distributed in my country, especially in Shaanxi, Guangxi, Anhui, and Sichuan. It is a commonly used raw material for crushing sand. After a series of processing such as crushing and grinding, it is widely used in construction materials and industrial materials. Its production line is also relatively common, with hourly output ranging from 100t to thousands of tons. Today, when the mechanism sand is hot, we often receive customers who want to go to a limestone production line to inquire about equipment configuration. Today, let's take a look at the crushing effect of limestone sand making machine!
The complex crusher is a sand making machine that integrates crushing and sand making. It has an efficient crushing capacity for limestone. It is widely used in machine-made sand and stone materials and metal ores. It is an ultra-fine crushing device. Because of its outstanding advantages of large crushing ratio, good particle size of finished product, small amount of abrasion, low energy consumption, good sealing, and easy maintenance, it has been favored by the majority of users.
Before understanding the complex crusher, we first give a brief introduction to its working principle. The material falls vertically from the upper part of the crusher into the impeller of the complex crusher rotating at high speed. Under the action of high-speed centrifugal force, it shunts and crushes with another part of the material around the impeller in the form of an umbrella. After the materials collide with each other, the material will form a vortex between the impeller and the casing, which will collide and rub against each other multiple times, and will be crushed, discharged directly from the lower part, forming a closed circuit multiple cycles, and controlled by the screening equipment to achieve the required particle size. It is precisely because of this working principle of the complex crusher that this crusher is widely used in the raw material and clinker fine crushing operations of cement plants, and can also be used for dolomite, coke gemstone, lead-zinc mine, serpentine , Blast furnace slag, coal gangue, phosphate rock and other medium-hard materials fine crushing operations, especially suitable for hard limestone, dolomite, granite, basalt and other artificial sand or highway road stone processing and crushing.
From the point of view of crushing effect: the vertical complex crusher has a large crushing ratio, so there is no problem with the crushing of limestone. The output particle size can be adjusted arbitrarily and is not affected by the wear of the hammer and lining.
From the perspective of equipment structure: the rotor body with compound limestone composite is unique. When the limestone is crushed, the rotor body is hardly worn. The rear cavity is provided with a screw or hydraulic opening mechanism. It is easy to replace the wearing parts without starting the main equipment.
From the point of view of crushing efficiency: the particle size of the limestone crushed by the vertical complex crusher can meet the production needs of users, which is conducive to the further processing of limestone, and at the same time, it is also conducive to the sale of the finished product by the user, and the finished product meets the needs of downstream users, with significant economic benefits.
From the perspective of finished product type: vertical complex crusher is suitable for crushing medium-hard and extra-hard materials, and is less affected by the moisture of the material, the moisture content can reach about 8%, the product is cubic, the bulk density is large, and the iron pollution is very small.
The PFL series vertical complex crusher produced by Luoyang Dahua Heavy Industry not only has the above-mentioned performance characteristics, but also has the crushing mechanism of impact and grinding. It can crush high-temperature materials below 150 ℃ (can be equipped with water-cooled chassis, high temperature bearing, resistant High temperature lubricating grease above 260 ℃), widely used in the crushing operation of raw cement and clinker, especially suitable for the technical transformation of cement plants, fine crushing equipment that achieves more crushing and less grinding, energy saving and consumption reduction.
