How To Choose Hammer Crusher For Limestone

The dpc single stage hammer crusher is used for usual fragile ore such as limestone, argillaceous siltstone, shale, gypsum, coal, etc.This type of crusher is used exclusively for cement production.It can also be used for crushing mixtures of limestone (marl) and clayey sandstone.The single stage hammer crusher can crush the ore block at the stope into the granularity required at the time.It can replace the traditional two-stage crusher and help simplify process flow, save infrastructure investment and production costs.Hammer crusher working principle the rotor of dpc hammer crusher is revoluting with high-speed in the driving system, the hammers head strike material with high velocity in the driving of rotor.Also break or thrown the stones, the material is crushed by the impact plate or broken by itself, then feed into the area where the grate plate and the grid working and be crushed again.The final product is discharged from the grid plate.Hammer crusher feture 1、large feeding size, high crushing ratio, high cost performance.2、the rotor adopts the whm two-step super hard surface deposited technique, and the service life of welding rods are over two times than that ordinary anti-abrasion welding rods.3、the construction of crushing cavity with our patent technology---"stone strike stone", which efficiently reduces the load of grid plate and the hammer head.4、hammer head is made of amc composite material which is developed by our company independently.The service life of the hammer is 50-150% longer than the hammer which is made from mn18cr2monbre.5、with special dual iron removing protection device, it can removing the iron ant others automatically.6、new design of grid plate, the material flow smoothly and stably, the size is fine and even, and the service life of the grid plate is long.Limestone crusher application to cement industry the main raw materials used in the cement manufacturing process are limestone, sand, shale, clay, and iron ore.The main material, limestone, is usually mined on site while the other minor materials may be mined either on site or in nearby quarries.Another source of raw materials is industrial by-products.The use of by-product materials to replace natural raw materials is a key element in achieving sustainable development.Mining of limestone requires the use of drilling and blasting techniques.The blasting techniques use the latest technology to insure vibration, dust, and noise emissions are kept at a minimum.Blasting produces materials in a wide range of sizes from approximately 1.5 meters in diameter to small particles less than a few millimeters in diameter.Material is loaded at the blasting face into trucks for transportation to the crushing plant.Through a series of crushers and screens, the limestone is reduced to a size less than 100 mm and stored until required.Depending on size, the minor materials (sand, shale, clay, and iron ore) may or may not be crushed before being stored in separate areas until required.Dsmac own many years of r&d in the industries of cement crushing and grinding, artificial sand making, and wear resistant materials as a whole profit model for cement plant.As we all know, comparing with the natural sand, artificial sand has enjoys excellent overall performance such as hardness cleanliness, etc.Nowadays more artificial sand played a more and more important mainstream role in the market.In artificial sand production process, the greatest waste is generated the largest number of powder (about 25%) waste, which is precisely the ideal raw material for cement production.We can slightly modify the original limestone crushing production line, to achieve both the goals, to both the goals, to provide high-quality fine material to cement companies, and also provide stones, artificial sand to market.
