Working condition of concrete mixing plant

<p>The dust cover of the PYFB-2127 type cone crusher is fixed on the supporting sleeve by 8 lock cylinder of &Phi;150mm. when the pressure reach 12 MPa, the coupling mechanism force can reach 170 tons. During the working process of the cone crusher <a href="http://www.smalldieselcrusher.com/diesel-jaw-crusher.html">mobile crusher price</a>, the lock cylinder and the insurance cylinder can be used to keep the adjusting sleeve, the supporting sheath and the engine base together to make the cone crusher at its normal working.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:<a href="http://www.smalldieselcrusher.com/army-mobile-jaw-crusher.html">mobile crusher plant</a>,<a href="http://www.daswellmixer.com/product/Concrete_Batching_Plant/20130927/19.html">concrete <a href="http://www.daswellchina.com/products/concrete-batchingplants/ready-mixed-concrete-mixing-plant.html">batching plant</a></a>s,<a href="http://www.daswellchina.com/products/concrete-mixers/diesel-concrete-mixer.html">concrete mixer</a>,blocking making machine,concrete pump,etc. <p> <p>The overload protection function of the PYFB-2127 type cone crusher is realized through the accumulator filled with nitrogen. The gas pressure in the accumulator is high than the oil pressure in the insurance cylinder. Thus, the oil cannot get into the accumulator in normal working. However, when the abnormal materials get into the cone crusher, the adjusting sleeve will be jacked up, with the adjusting sleeve going up, to push the oil in the upper cavity of the insurance cylinder to the accumulator. Then, the discharge port will be enlarged to eliminate the abnormal materials to realize the insurance of the machine. After the abnormal materials being eliminated, the gas pressure will be higher than the oil pressure, and the oil getting into the accumulator will be pressed into the hydro-cylinder again, resulting in the normal working condition of the crusher.</p>
