Coal crushers are a new type of exclusive equipment launched by Liming in response to the current situation of the coal industry. Their distinctive feature is low consumption, and they are non-screen bottom crushers, which can crush wet and dry materials, so they have a wide range of applications.For example, coal, coal gangue, slag and other materials, etc., and the finished products crushed by Liming Coal Crusher have uniform particle size, standard particle type, and reasonable grade.Next, I will recommend Liming Coal crusher for you!
Recommended for large-scale coal mining equipment
1. C6X jaw crusher
Through the optimization of the cavity structure of the crushing cavity and the trajectory parameters of the moving jaw, a reasonable moment of inertia and a larger crushing stroke make the equipment more efficient in crushing under the same energy consumption
The integrated motor seat design, the motor seat is fixed and installed on the crusher, which reduces the installation space and makes the power transmission more stable.
The elastic limit block and rubber shock absorber are used to replace the rigid foot connection, which effectively absorbs the peak vibration load, thereby reducing the mutual impact between the crusher and the foundation and improving the service life of the equipment.
The frame adopts the separation design of the side walls and the front and rear walls, and replaces the previous welding frame by bolting and fixing, which avoids the stress concentration caused by welding and makes the structure more compact and reliable.The damaged main parts can be replaced, which greatly improves the life of the equipment and saves customers more cost investment.
Wedge adjustment replaces the traditional pad-type discharge port adjustment, making the discharge port adjustment operation simpler.
2. HPT cone crusher
Adopts an optimized structure of fixed spindle, small ball surface shaft, etc., which is 5%-15% more efficient than spring cone breaking.
The combination of crushing stroke, crushing speed and crushing cavity type is 35%-60% higher than the output of spring cone breaking.
Using the proprietary lamination and crushing principle, the proportion of neutral cubes in the finished product is significantly increased, the needle-like particles are reduced, and the grading is more reasonable.
When debris enters the cavity, the iron protection device will automatically release it, and then reset it immediately, without affecting the normal operation of the equipment.
On-site case analysis of pulverized coal preparation project
Russian pulverized coal preparation project
Generally speaking, pulverized coal refers to coal with a particle size of less than 0.5mm. The preparation of pulverized coal refers to the process of processing raw coal into pulverized coal whose particle size and moisture content meet the requirements of blast furnace coal injection through a coal grinder.The requirements of the blast furnace spraying system for pulverized coal are: the particle size is less than 74μm accounts for more than 80%, and the moisture is not more than 1%.Liming Heavy Industry LM type pulverized coal vertical mill (medium-speed coal mill) can be used in pulverized coal boilers, blast furnaces, coal chemical industry, lime kilns, rotary kilns, metallurgy, electric power, cement and other industries.It has gained a good reputation among customers in various industries.
Processing materials: coal Output : 20-25T/H Feed particle size : 30mm Finished product fineness : 200 mesh
On-site situation : At present, this LM1700 vertical mill is undergoing preliminary commissioning and has not yet been officially put into operation, but the layout of the site is orderly, from the silo, belt conveyor, raw coal silo, closed quantitative coal feeder, vertical mill, dust collector, fan, silo pump to the final finished pulverized coal silo, every project is strictly checked, and the project is progressing smoothly.
Australian pulverized coal preparation project
The main pulverized coal preparation equipment configured is LM1500 vertical coal mill, the rated power of the whole machine is 600KW, and the desulfurization, denitration, and dust removal devices are integrated and installed, so that the combustion efficiency of the pulverized coal boiler is increased, the output is increased, and the pollutant emissions are reduced. It is an ideal equipment for pulverized coal preparation, power plant desulfurization, cement, and slag grinding.
Processing materials : Bituminous coal Output : 18-22T/H Fineness of finished product : 200 mesh=D80
On-site situation : Raw coal is fed into two LM1500M vertical coal mills through a closed quantitative coal feeder. At the same time, the hot air from the heating furnace enters the vertical coal mill from the air inlet under the suction of the system fan. After sufficient heat exchange with the raw coal being ground in the mill, the pulverized coal is brought up and sorted at the separator. The coarse pulverized coal with unqualified fineness falls back to the grinding disc for grinding, and the pulverized coal with qualified fineness enters the explosion-proof air box pulse dust collector with the air flow. After collecting, the collected finished pulverized coal passes through the discharge port and is fed by the conveying device into the next link for use.
