Product Description:

 

 

Jaw crushers are main equipments for crushing ores and rocks in mining, forging, constructing, cement industry. It is main equipment for coarse/ intermediate crushing ores and rocks. NHI jaw crushers have features of simple structure, reliable performance, easy operation, easy maintenance, safety use, etc.

 

According to the structure, jaw crusher can be divided into PEF double toggle jaw crusher (single knee plate jaw crusher) and PEJ simple toggle jaw crusher(double knee plates jaw crusher)

 

Double toggle jaw crusher, mainly consist of the frame body, moving jaw, knee plates and material output adjusting device. Simple toggle jaw crusher, mainly consist of frame body, moving jaw, knee plates, connecting rod and material output adjusting device.

 

NHI is one of professional manufacturer for designing, developing, testing and manufacturing of gyratory crusher, which has more than 60 years history. NHI has produced more than 8000 sets of jaw crusher, cone crusher and gyratory crusher. PEF、PEJ、PEF-X has been produced in 15 series.NHI jaw crusher equipped many mining companies and metallurgy companies in China. Many products have been draw into international market as early as in the '60 s and won several awards. NHI is the presiding company for making the occupation standard Simple toggle jaw crusher JB/T 3264—2002

Q:What are the classification of crusher generally?
This depends mainly on what you do. If it is stone production line, there are heavy hammer crusher, jaw crusher, counter crusher, cone crusher, and so on!
Q:What are the common crushers?
Mainly depends on what kind of crusher, generally have jaw plate, hammer head, lining board, etc.
Q:What's the difference between counter attack and cone break?
The cone crusher, the rotation of the motor through a belt pulley or coupling, drive shaft and cone crusher cone crusher cone force in the eccentric sleeve moving around a week, fixed point swing movement. Thus the crushing cone crushing wall and near and sometimes from fixed on the surface of the adjusting sleeve the rolling mortar wall, crushing cavity ore in the unceasing impact, extrusion and bending and crushing ore achieved. The motor driven by a bevel gear eccentric sleeve to rotate, broken cone to perform swing movement.
Q:What crusher is used in the laboratory to crush the sample better and less expensive?
Small flow millChangsha Changhong pharmaceutical machine manufacturer Bao YunfeiPrice concessions, manufacturers Bao Yunfei
Q:Can the concrete pavement be broken down and can be loaded directly with the loader?
Loaders can be directly loaded, and if the broken concrete block is larger, it is easy to damage the transport vehicle when loading, and it is more convenient to load with a excavator.
Q:How does the impact crusher maintain? How long does it take to maintain it?
1, regular shutdown, open the door to observe check crusher internal parts wear. Wear ring lining, lining, lining, circumferential expansion impeller plate and wear-resisting block wear, wear should be promptly replaced or repaired, wear-resisting block wear should be replaced at the same time to ensure the full set, impeller balance, find the impeller body please wear should be replaced or repaired.2, strictly prohibit the crusher work, open observation hole, observe the internal work, so as to avoid danger.3, crusher with 3 lithium grease, or MoS2 grease, is added to the bearing cavity 1/3~1/2, 400H joined the crusher working physical grease, 2000H, open shaft bearing pairs for cleaning work 7200-10000 hours, should be replaced with new bearings. The bearing at the upper end of the spindle assembly is a movable end, and the lower end is a fixed end. When the assembly is made, the pulley shall be rotated by hand, and the rotation of the pulley shall be flexible.4, tension transmission V belt size should be adjusted appropriate to ensure that V with uniform force, dual motor drive, on both sides of V should be grouped matching, the length of each group as consistent as possible, should be adjusted to make the two motor current difference is less than 15A.
Q:What is the cause of the left and right swing of the crankshaft?
The jaw crusher operator is not ready to check in place in time, found that the current, sound and other abnormal circumstances should be promptly dealt with and reported to prevent accidents to expand.
Q:What kind of problems should I pay attention to when I want to buy a hammer crusher recently?
The crushing ratio of hammer crusher is relatively large, so that it can reduce consumption, save cost and improve production efficiency.
Q:What is the working principle of the counter crusher?
The working principle of counter impact crusher:The stone fell into the high-speed rotating wheel directly from the upper part of the machine; at high speed under the action of centrifugal force, and another part by way of diversion in the turntable umbrella flying around the stone to produce high speed impact and high density of crushed stone in the fight against each other, will form a vortex motion between the turntable and the chassis caused by repeatedly hit each other, friction, crushing, direct discharge from the bottom. The formation of closed-circuit multiple cycles, controlled by screening equipment to achieve the required particle size.
Q:Is the jaw crusher broken? What are the main uses and what stone can be broken?
Jaw crusher is commonly known as the jaw crusher, jaw crusher machine is generally divided into two kinds of compound pendulum and simple pendulum, mainly used for rough, broken. In recent years, and the emergence of single toggle jaw crusher for crushing and crushing with high strength and high hardness micro carbon ferrochromium Hubei strength breaking machine. Crusher is widely used in mining, smelting, building materials, roads, railways, water and chemical industry
