Product DescriptionHammer crusherWorking PrincipleThe rotor driven by the electric motor rotates at high speed. After entering the crushing chamber from the upper feed port, the material first undergoes initial crushing due to the impact, shear, and tearing effects of the high-speed rotating hammer heads. Then, the material is thrown against the counter-impact plate or the inner wall of the machine case, achieving secondary crushing through impact. Materials that do not meet the granulation requirements will be repeatedly ground between the hammer head and the sieve until they pass through the sieve gaps and are discharged outside the machine. This "impact - counter-impact - grinding" multiple crushing mechanism allows for high crushing efficiency and uniform particle size.SpecificationApplications 1Mining and quarrying2Construction and building materials industry3Coal and power industry4.Metallurgy and chemical industry5Environmental protection and solid waste treatmentKey Configurations 1.Hammerhead(Core working components)2.rotor(Power transmission and load-bearing core)3.Crushing chamber (material crushing and screening space)4.Transmission system (power output core)5.Bearing and lubrication system (to ensure stable operation of the rotor)6.Safety protection devices (equipment and personnel protection)7.Housing (structural support and sealing)Key Configurations1. Operating Parameter Settings (Core Performance Control)Rotor SpeedSpeed is the core parameter that determines crushing capacity:The higher the speed, the greater the hammer's impact kinetic energy, making it suitable for crushing hard and brittle materials (such as ores) or when finer particle size is required.A speed that is too low results in insufficient impact force, which can lead to incomplete material crushing and reduced efficiency.Adjustments should be made based on material hardness (e.g., limestone ≤ 150 MPa, coal ≤ 50 MPa) and the target particle size. This is typically achieved by adjusting the motor power and pulley ratio (which must match the equipment's rated speed to avoid overloading).Feed Rate Control2. Crushing Particle Size and Chamber ConfigurationGrate gap (or impact plate gap)This is the "direct switch" that controls the discharge particle size:The smaller the grate gap, the finer the discharge particle size (e.g., 3-10mm is suitable for sand making, 10-50mm is suitable for aggregates).If the gap is too large, there will be too many coarse particles, requiring secondary crushing.Note: The gap should be adjusted according to the material characteristics (e.g., for sticky materials, the gap should be increased to prevent clogging, while for hard materials, the gap can be reduced to improve crushing efficiency). The grate bars must also be installed flat to avoid leakage or jamming.Gap between hammer head and crushing chamberSome hammer crushers are designed with adjustable impact plates or side linings. By adjusting the distance between the impact plates and the hammer heads (usually 50-150mm), the following can be achieved:Smaller gaps increase the number of times the material is struck and rebounded by the hammer heads within the chamber, resulting in more complete crushing (more uniform particle size).Larger gaps facilitate rapid material discharge, making it suitable for processing bulky materials, but may result in a coarser particle size.Product ParametersModel200*300300*400310*520Power(kw)5.57.515Capacity(t/h)3-45-77-10Weight(kg)150350550Size(mm)1100*600*10701200*670*12901300*730*1360After Sales ServiceStandard Warranty: 12 months or 2,000 operating hours (whichever comes first).:12 2,000 Global Support: 24/7 technical assistance and spare parts supply.:24/7 .Training: On-site or remote operation/maintenance training.Why Choose Us?Other ProductsOEM/ODM capabilitiesCompetitive pricing & bulk discountsFast shipping & customs clearance supportTurnkey project solutionsHenan Yongshuo Heavy Industry Equipment Co., Ltd.
