Henan DEWO crushing equipment improves limestone recycling
Construction of tunnels and construction of high-rise buildings; no corrosion in the environment of salt and acid rain, and no corrosion of internal structural steel bars; it can be solidified in only 1 hour under water operation, and it can be used for rescue and construction of seawalls, etc. Never changing color is another characteristic of this cement. Because it is a mineral color, it will not fade in any environment. White is the color of china clay and red is the color of clay.
As we all know, the main raw material for cement production is limestone. In Kaishan quarrying, ordinary equipment is mainly used for impact crusher. Henan DEWO stone crusher machine manufacturer provides cement production mainly for mixed crushing, which means that the two raw materials in cement production are sent to a impact crusher in a certain ratio for crushing production. Craft. Common types of mixed crushing include limestone and marl, limestone and shale, limestone and clay, etc. Among them, the mixed crushing of limestone and clay is the crushing of two materials with very different physical properties, especially when it is mixed with high plasticity and high moisture mud. The hydraulic impact crusher is a new generation of high-level, high-quality products that Henan DEWO stone crusher machine manufacturer absorb the current international impact crushing technology. The rotor is the “heart” of the crusher, and it is also a relatively strict part of the impact crusher, which plays a vital role in the work
Therefore, the company has developed and produced a heavy-duty rotor with a solid structure to obtain a higher moment of inertia. High wear-resistant materials and ideal crushing cavity make the impact crusher have obvious advantages. The mixed crushing process composed of hydraulic impact crusher brings the following benefits: during the crushing process, the limestone crushed material is wrapped by the wet material, the dust is reduced, the viscosity of the formed crushed stone and the wet soil mixture is reduced, and the fluidity Increase, reduce the blockage of the chute, and have the performance of transporting with a belt conveyor and storing and rake in the pre-homogenization yard.
The success of mixing and crushing can reduce or even eliminate the stripping of limestone topsoil and make fuller use of ore resources. The two raw materials are processed together to reduce the construction and operating costs of a processing system. The cement mixing and crushing process ensures that the discharge particle size meets the requirements of the mill, prevents the crusher cavity from clogging, and ensures the smooth operation of the entire system. Therefore, the entire system from the silo must be specially designed, including the shape and structure of the silo, the cutting of the mud before crushing, the special treatment of the inside of the machine body and even the funnel, chute, etc., and the hydraulic impact crusher of the Henan DEWO stone crusher machine manufacturer It has achieved good social and economic benefits in the mixing and crushing of cement production.
Hydraulic impact crusher is very suitable for crushing various soft and medium hard ores, for coarse crushing, medium crushing and fine crushing. It can process slag, coal gangue, fly ash and other materials with jaw crusher, which can replace limestone and produce cement . A kind of geology with clay high-alumina materials and industrial waste residues (such as slag, fly ash, coal gangue) as main raw materials, adding 5% special additives, firing temperature only 700 degrees Celsius, energy consumption only 1/2 of ordinary cement The new polymer cement technology does not require limestone, has low fuel consumption, and can reduce coal combustion by 50%, so dust and exhaust gas are greatly reduced, and 50% of the raw material is waste residue. The tensile strength of this cement is 2～ that of ordinary cement. 3 times, for example, only half the thickness is used to build roads. Using this kind of cement to build highways can save considerable money every year. Non-cracking is another characteristic of this cement.
