horizontal impact crusher
horizontal shaft impact (hsi) crusher is widely applied in primary and secondary crushing operations. it offers big crushing ratio, high reliability, uniform particle size, low maintenance and wear costs, and low downtime, etc.
the hsi crusher is mainly composed of heavy-duty impeller shaft, curtain liners, adjustable lining plate with high rotational inertia, and a horizontal rotating shaft to which a rotor is attached. the horizontal shaft is placed inside the crushing chamber, which is lined with replaceable plate hammers. the materials will be fed into the top of the chamber, and then the rotor throws the materials out against the blow bars. in this way, through repeated impacting process, the crushing operation can be finally completed to get the desired particle sizes.
horizontal impact crusher provides a large crushing ratio to reduce secondary crushing operations and improve production capacity. its firm and durable structure guarantees a long service life and constant operation as well. what’s more, each of our manufacturing process is under strict quality control system in order to ensure high performance and durability. our horizontal impact crusher is developed with accurate composition of heavy rotor design, crushing chamber and wear parts to improve crusher’s productivity and at the same time reduce operation costs.
impact crusher operation
impact crusher is a new-style high-efficiency crushing equipment. it is suitable for coarse, medium and fine crushing of a variety of materials with feeding size not more than 500mm and compressive strength less than 350mpa. usually the materials that can be crushed by impact crusher mainly involve slags, clinkers, limetsone, coal, and coke, etc. impact crusher is extensively used for secondary and tertiary crushing of different hard and medium-hard materials in the fields of energy, cement, railway, highway, construction, chemical industry and so on. normally, the particle size is adjustable, and at the same time various crushing specifications are available. the crushing ratio can reach up to 40.
how impact crusher works
during operation, the electric motor of the impact crusher will drive the rotor to rotate at a high speed. under the action of the hammer that is mounted on the rotor, the materials will be thrown to the impact device above the rotor continuously. then the materials will be rebounded from the impact lining plate to the position where the hammer has an effect, so the crushing process can be completed. the materials of large size or small size will be crushed repeatedly in the crushing chamber. the impact crusher will not stop operating until all the materials are crushed to the suitable particle size and then discharged from the discharge port.
prominent advantages of impact crusher
big feed inlet, high crushing chamber, strong adaptability to materials of high hardness, and final products with little stone dust;
the gap between the impact plate and the plate hammer is convenient for adjustment, which is beneficial for the control of particle size and grain shape;
the impact crusher is with compact structure and strong rigidity, and meanwhile the rotor is with large inertia moment;
high-chromium plate hammer features excellent impact resistance and abrasion resistance properties;
keyless connection is economical and reliable, and meanwhile brings convenience to overhaul;
complete crushing functions, high production capacity, low rate of abrasion, and high overall efficiency.
impact crusher operation and maintenance tips
impact crusher is a crushing machine of high rotation speed and large inertia moment. in order to guarantee the impact crusher operation is under normal conditions, the tips listed below should be followed:
1. before starting the impact crusher, it is suggested that you should make a rigorous testing first.
2. during the operation of the impact crusher, make sure to check the lubrication system regularly.
3. ensure a uniform feeding of materials so as to avoid large-size stones that can’t be crushed getting stuck in the crushing chamber.
4. regularly examine the operation conditions of the blow bar and replace it if necessary, so that the impact crusher can maintain a relatively long service life and thus achieve long time running.
5. make sure to keep the machine sealed in order to prevent the dust from flowing into the air.
