why the bowl - shaped bearing seat of cone crusher appear  loosening, skewing, swing




1. The bowl - shaped bearing seat shall be installed on the base. The bowl - shaped bearing seat shall be closely matched with the base and a feeler shall be used to check the tightness of the horizontal contact surface.If the clearance fails to meet the assembly requirements, the bowl - shaped bearing seat loosening, skewing, swing will occur.

2, crusher too iron or feed does not meet the performance requirements of the equipment, that is, if the crusher too iron over the ore discharge mouth particle size, feed particle size is too large or material is too large, will cause crushing captain time vibration, and then cause bowl bearing seat and base wear, can not meet the assembly requirements will appear in the above situation.

3, bowl bearing seat and the base assembly design is unreasonable, bowl - shaped bearing seat installation requirements is a tight fit, due to the site installation, spare parts size is bigger, does not have interference assembly condition, is to design a shaft pin as a limit, the crusher through the iron more than discharge ore granularity, feed particle size is too large, or feed capacity too large crusher vibration caused by circumstances, it is very difficult to limit.

Common knowledge of mineral processing

Common knowledge of mineral processing 1. What is productive rate? In the dressing process, the weight of a product and the percentage of raw ore weight, known as the productive rate. The production rate of each product is calculated as follows: Concentrate mineral rate 1=Q1/Q 100% Medium mineral rate 2=Q2/Q 100% Tail mineral rate 3=Q3/Q 100% Where Q -- raw ore weight, t;  Q1 -- concentrate weight,t; T Q2 -- medium ore weight, t;   Q3 -- tailings weight, t. What is the recovery rate? The concentration recovery is the percentage of the amount of metal (useful component) in the concentrate to the amount of metal (useful component) in the raw ore.This is an important mineral processing index, which reflects the degree of metal recovery, mineral processing technology and mineral processing quality.The recovery of ore dressing should be improved as much as possible on the premise of ensuring concentrate grade.The calculation method is as follows: 3. What is the Ore dressing ...

How much is a set of quarry plant, what equipment does it use? As we all know, gravel is a common material such as construction materials and highway construction materials. The plant mining gravel is called gravel yard, and the plant processing gravel is called gravel yard or stone factory. Granite is about 120~200MPa.Primary crushing usually adopts jaw crusher , which uses the extrusion and bending effect of two jaw plates on materials, crushes the crushing machinery of various hardness materials.The secondary crushing usually adopts impact crusher to produce the particle size of materials.SHUOSEN machine to recognize 300 tons per day of 300mm counterattack crusher feed particle size, discharging size and shape can be adjusted according to customer demand for multi-functional.In addition to the impact crusher, also can choose SHUOSEN machine spring crusher, cone crusher. Main factors for equipment selection can be summarized as follows: (1) the crusher is stable with continuous fee...

How to reduce the dust of jaw crusher

How to reduce the dust of jaw crusher ? Source of jaw crusher dust Dust is initially caused by ore crushing, part of which is carried by the ore itself, and part of which is generated in the later stage of ore crushing.The general movement trajectory of the ore is as follows: the ore enters the machine from the feed port, is broken to the relevant particle size in the machine, is discharged from the discharge port, and then is transported to the next section of processing equipment by the belt conveyor.It can be seen that the devices that directly contact dust with air are inlet, outlet and belt conveyor.In addition, the use of hopper, protective cover, chute and other materials in the production process will produce a certain height difference, which is another major cause of dust. To solve the problem of jaw crusher dust , the first is to control the dust source with the help of external force to avoid its diffusion, and the second is to improve the local structure of the machin...
