Product Description:

Hammer crushers are main equipment for intermediate crushing the limestone, coal and other brittle materials below medium hardness in mining, constructing, chemical and power stations. The crushers have the feature of high crushing rate, high output rate and their products have even grains.

 

According to the structure, hammer crusher can be divided into horizontal type hammer crusher and vertical hammer crusher. According to the using requirements, hammer crusher can be divided into reversible, irreversible hammer crusher, single stage hammer crusher and dry-type hammer crusher. Reversible hammer crusher with reversible rotor used for fine crushing in general; irreversible hammer crusher with irreversible rotor used for intermediate crushing.

NHI has more than 60 years history of designing and manufacturing hammer crusher. Over 1000 sets of hammer crusher were produced and exported to many other countries. NHI hammer crusher is been produced in series. These products are welcomed by customers for their variety of models, advanced design, reliable capacity, stable running and low consumption of energy.

 

NHI is the presiding company for making the occupation standard hammer crusher for coal JB/T 3765—2008 and hammer crusher for limestone JB/T 3766—2008.

Q:What kind of crusher is it?
We just want to start a business that was also doing a variety of market research, and then look at the many machines, and finally chose the price relative to other high Donglong heavy industries, the quality is also good, I also give you our advice.
Q:Is there a broken stone crusher with a diameter of more than 800mm? The ordinary crusher costs too much. I saw it on the Zhengzhou GM
It can be broken in two forms, dry, wet, suitable for mines, cement, coal, metallurgy, building materials, road, burning and other departments to crush medium and medium hardness and brittle materials.
Q:What are the hammer crusher models? What's the approximate size of each model?
Heavy hammer crusher, single stage hammer crusher, ring hammer crusher, reversible hammer crusher, hammer crusher
Q:What crushing machine does asphalt recycling break?
Asphalt material adopts the crusher can build the system
Q:Which type of coal test crusher is good? Which kind of crushing method is good?
Brand: Kaiyuan, Sande, Corey, Fengtai, Kaiyuan three refined,13mm suggests a jaw crusher, a hammer type6mm hammer crusher3mm recommends the counter roller crusher0.2mm milling machines are the same. Hope to adopt.
Q:Why does the hammer crusher work with strong vibration?
Check whether the crusher parts are loose, after the power supply, first check the direction of the main shaft and arrow pointing in the same direction. Before starting, check whether the fasteners are loose or not and the degree of tightness of the belt. The first air around 1-2 minutes before work, Hebi China coal laboratory equipment crusher confirmed no abnormal sound, we can begin to work. In the initial job, try to work with fewer materials before putting them into formal production.
Q:Where is the crusher used?
The auxiliary materials are mainly counter crusher and roller crusher. As for the conveyor belt, the most important is the belt conveyor, the use of a wide range of mining enterprises are basically used.
Q:What's wrong with the lubrication system of the crusher? How can we solve this problem?
Spare parts and materials consumption increased, energy consumption increased and production cost higher. As the oil often produce high temperature, so the lubricating oil consumption increased very quickly; and a large amount of consumption of lubricating oil pump, accelerated wear crusher parts, resulting in equipment maintenance costs; ore size in each crushing section can not meet the requirements, increase the amount of closed-circuit circulation, screening equipment and transport equipment increased wear the energy consumption in the cycle, unnecessary transportation of ore in.
Q:What is the advantage of a jaw crusher made of large and medium-sized plain pendulum?
The material distribution in the crushing cavity is: the material in the upper cavity is larger, and the material in the lower chamber is smaller. The larger block requires a larger crushing stroke, while the smaller one is just the opposite. If the large material requirements are met, the horizontal stroke of the discharge port is too large, and the product granularity can not be guaranteed.
Q:How long is the crusher hammer used in general?
Different stones will have different degrees of wear, Zhejiang Shengda mechanical hammer after excellent heat treatment process, under the same material, wear resistance increased by more than 20%, longer use time,
