Comparative analysis of the impact crusher and hammer crusher seven differences

Impact crusher and hammer crusher as ore crushing equipment is often compared, from the crushing principle to the structure of the equipment have certain similarities and differences, the same is the use of high-speed impact to achieve the principle of stone crushing, the differences are mainly manifested in the following 7 aspects, the following we design structure, working principle and scope of use to do a detailed introduction.

1. Main structure: impact crusher consists of rotor, impact plate, frame, impact plate, even grate plate, transmission parts, impact plate rigidly connected to the rotor; hammer crusher by the rotor (spindle, hammer frame, hammer head, pin) frame, crushing plate, screen plate, transmission parts, etc., hammer hinged on the hammer frame.

2. Crushing cavity: the former crushing cavity is larger, so that the material has a certain activity space, make full use of the impact, while the latter crushing cavity is smaller, the impact can not give full play to the role of the impact, and the impact broken for the multi-cavity crushing structure, crushing full.

3. Outlet sorting device: impact crusher does not have castor and other screening structures, by adjusting the device to achieve the sorting of material size particles, hammer crusher has a castor to control the fineness of stone particles.

4. Crushing principle and direction of force: the use of the inertia of the rotor on the material impact crushing (free crushing, impact crushing, milling crushing) the material to obtain the speed and kinetic energy is larger, the hammer upward countervailing blow to the material, the crushing effect is large, the hammer using a single hammer on the material impact crushing (free crushing, impact crushing) the material to obtain the speed and kinetic energy is limited and the hammer downward homeopathic blow to the material, the crushing effect is small. The hammer head strikes the material in a downward direction, the crushing effect is small.

5. Analysis of wear resistance of wearing parts: the rotor of impact crusher is not easy to wear, while the hammer plate and end plate of the rotor of hammer crusher are easy to break, and need to be repaired or replaced regularly, and the wear of impact crusher hammers is not serious when crushing limestone, but the hammers need to be replaced constantly when crushing granite.

6. Finished product size: Impact breakers are mainly determined by the rotor speed and the gap between the outer edge of the rotor and the homogenizing grate plate, 80% of the finished product size is less than 30mm, and the product size is controlled by the width of the gap between the grate bars, and there is a certain gap in the finished product size according to different models.

7. Application scope: both are used with medium-hard materials, but the impact crusher is mostly used as secondary crushing equipment, while the hammer crusher is mostly used in cement production line, which can be used as crushing equipment for raw materials of limestone, and can also be used as primary crushing equipment in sand and gravel co-production projects.

There is a big difference between the impact crusher and hammer crusher, both belong to the stone production line commonly used equipment, with simple and convenient operation, price concessions and other features trusted by customers, here we look at the impact stone crusher seven advantages are?

1. The gap between the impact plate and the hammer can be easily adjusted, effectively controlling the particle size of the material, the particle shape is good.

2. The ore is crushed along the nodal surface, so the power consumption is low and the efficiency is high.

3. High chrome plate hammer, anti-impact, anti-wear, impact force.

4. Simple structure, small volume, light weight, large production capacity and low production cost. Large feeding opening, high crushing cavity, high hardness of adapted materials.

5. Keyless connection, easy maintenance, economic and reliable.

6. Full crushing function, high productivity, low wear and tear of machine parts, high comprehensive efficiency.

7. The crushing ratio is large, up to 40, so it can simplify the crushing process, which can make the three-stage crushing into two-stage or one-stage crushing, and reduce the cost of mineral processing plant equipment.
