How To Assure The Sureness And Regualting Discharge Of The Jaw Crusher ?

Jaw Crusher thrust plate is also known as toggle, in addition to transmit power to move jaw plate back and forth, but also has a security role as insurance, to change its length can also play a role in regulating discharge mouth.
When there is material that can not be crushed into cavity (eg, iron balls, iron, etc.), in order to protect equipment from damage, the back thrust plate is used as insurance unit of crusher. The back thrust plate is usually with cast iron cast as a whole, open a slot or a number of holes as cross-section to reduce its intensity; it can also cast with two parts, and then use screws to connect together to form a combination thrust plate. When things can not be broken into the crushing chamber, the equipment overload, large broken power passed to the thrust plate, then thrust plate to break or cause a combination thrust plate screws cut, the machine stopped working, so it plays a role of insurance

As constant wear and tear of tooth plate, discharge mouth gradually become larger, the output production become bigger and thicker, in order to obtain a qualified product size, need to periodically adjust the discharge mouth size. Discharging opening adjustment methods are mainly the following two:
(1) gasket adjustment, that is after the thrust bearing plate between the posterior wall of the back seat and put a rack pads, change pads or change the number of its thickness, we can achieve the purpose of regulating discharge mouth. This method is compact, adjustable, reliable, large, large or middle size jaw crusher use this adjustment way.
(2) wedge adjustment, the thrust plate is placed between the two rear seat and rack wedge adjustment, which is suitable for small jaw crusher.




Reducing dust and noise from wet grinding to protect the environment


Environmental problem of ultra-fine grinding is dust and noise pollution during wet grinding.

Dust problem in the ultra-fine grinding in the dry, more or less dust problems, feeding port, discharge port and the fan seal, due to fine particle size, the dust can easily fly from place to seal well. Solution approach is to maximize the use of negative pressure system, with a good seal and fine grading equipment, crushing equipment, if necessary, installation of dust removal system in the crushing plant to ensure clean production workshop, which pigments, dyes, fiber and toxic powder Powder is extremely important.

Ultra-fine grinding equipment, there are some vibration and noise, especially for vibration mill, ball mill, the noise up to 120dB, if necessary, set the isolation tank or a special isolation room, isolating powder equipment has now developed a number of ultra low-noise grinding equipment, such as the tower mill, mixing mill, etc. can be given priority, but the ultra-fine grinding bad environment, not the same requirements in different industries, mining, refractories, coal industry and other industries, the relatively poor condition and In the pharmaceutical and food industries need to clean. In any case, noise reduction is imperative.

Wet ultrafine grinding, no matter what kind of technology, especially the fine ceramics, powder metallurgy, inorganic non-metallic materials industry, the application of water, oil or alcohol can be recycled, which requires the dehydration of water or To filter the oil, in the case of raw materials to ensure no contamination can cycle applications.
