There may be some problems in the process, such as the sound of belt hitting when the belt is running off-track; the noise of stone hitting the hammer crusher when the discharge is blocked, and the hammer crusher should be dealt with in time after its shortcomings, reduce noise. The hammer crusher has its own vibration.
The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches).
The noise of the empty operation of the multi-cylinder hydraulic cone crusher should be less than 90dB. When the noise exceeds 100dB, it indicates that the crusher is operating abnormally, which will affect the performance, production capacity and service life of …

Cone Crusher Maintenance 1. 8 Hours 1.1. Check the level of oil in the oil tank, oil temperature, oil flow in the sight feed gauge or oil pressure if so equipped, and oil flow back into the oil tank 1.2. Check power draw on motor, tapered key for tightness, unusual noise, indications of wear, or undue strain on crusher parts 1.3.
A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is …
Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches). The material (throughs) from the second level of the screen bypasses the secondary crusher because it is sufficiently small for the last crushing step.
Crushers are widely used in mining, metallurgy, chemical and other industries. The emergence of crushers has solved the problem of material handling and greatly increased work efficiency. However, the noise problem of crushers has been plagued by enterprises. The noise not only affects the physical and mental health of …

A cone crusher has two sides: an open side and a closed side. As the material crushes, the particles that are small enough to fit through the open side fall through the space between the mantle and the concave. As the mantle gyrates, it creates a narrow point and a wide point.
The unsung hero of the entire machine, the motor is what drives the mantle and allows crushing to take place. These motors are incredibly powerful and capable of generating a massive amount of …
