JS1000 twin shaft compulsory concrete mixer electrical system: electrical control circuit has a circuit breaker, thermal relay, with short circuit protection, overload protection function. All controls and indicators are arranged on the control box door, and a door, outside button has a protective door. Distribution box of the electrical component mounting board in the electrical installation, safe, reliable, easy operation and maintenance. The total electric power supply is AC380V three-phase five-wire (or three-phase four-wire) power supply voltage tolerance ± 10%, otherwise prohibited. Control power to AC220V. Surface temperature of the motor ￡ 60 ° C, the charged portion of the shell insulation 30.5MW. Compulsory concrete mixer, including the mixing tube, stirring cylinder equipped with a stirring shaft concrete mixer, agitator shaft at both ends of the mixing tube at the wall of the installation of a side arm with a stirring shaft end for cleaning the wall, on both sides between the arms both sides of the midpoint of the installation of a set of spiral arrangement of mixing arm, two mixing arms arranged in the axial direction from the both ends of the arms to the arm in the direction of rotation of the arrangement were made from the end of the arm to the arm, each of the top arms are fixed stirring with a stirring blade, arranged on both sides of the arms are behind the rotational direction end of the arm on the same side of the mixing arm. The utility model side arm in the rotation direction of the overall layout of the stirring arm positions retreat to behind the end of the arm on the same side of the mixing arm set, so that when the actual work, the smaller side arm working resistance, and the mixing tube Cutting between 250 without cement mixer, so to improve the durability of the side arm, stirring shaft drive force required cement mixer 350 is reduced, and therefore low-power motors may be fitted, to reduce the manufacturing cost, power consumption is reduced accordingly. 350 cement mixer, Lei machinery (online consultation), cement mixers are provided by Lei Machinery Co., Ltd. Zhengzhou. Zhengzhou Lei Machinery Co., Ltd. (www.hnzljx.net) (www.hnzljx.net) is a leader in Zhengzhou, crushing grinding equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum Limits to meet customer needs. In Lei machinery leadership with the staff warmly welcome all inquiries negotiations to create the better future Lei machinery.
