How to maintain the shredding machine working at high temperature during the hot summer. Any articles can not be exposed to the sun and it is our work shredder! Shredding machine in the processing of waste materials is not less equipment, motor is the primary base of equipment. If the motor is broken, then the equipment can not run normally, so to protect the motor part.

How to clean shredding mechanical and electrical machine shortcomings, the following manufacturers teach you a few small good method:

1. The motor department shall check whether the motor bearing is excessively worn or ill-equipped, which constitutes constant and rotor phase friction, causing surface damage of the iron core, which further constitutes a short circuit between silicon steel sheets, increasing the motor’s iron loss and making the motor’s temperature rise too high. Use a fine file and other things to remove burrs, eliminate silicon steel short joint, clean up after the coating of insulating paint, and heat drying.

2. Timely check that the connection between the motor core and the frame is loose when working at high temperature, and tighten the original locating screw. If the locating screw fails, the locating hole can be redrilled and tapped on the machine base to tighten the locating screw. Bearing defects maintenance shaft through the bearing support tumbling, is the heaviest some, is a brief wear parts.

With the development of scientific skills, the knowledge of metal breakage has also been greatly developed. Giant pellet metal selected by various different crushing methods, can be obtained a few microns of metal, with a variety of customary skills begged.

In the industry, the widely used metal crushing method is still mechanical crushing, mainly kneading, splitting, breaking, grinding and impact crushing. Non – mechanical force crushing has not been used in large industrial production.

Metal in the effect of external forces, the stress attack reached the ultimate strength, the metal is broken. Shredding mechanical force method has the following.

A crushing: the metal is placed between two kneaded surfaces. After applying the force, the metal is crushed due to the compressive stress reaching the compressive strength limit.

B: the metal is placed between a plane and a tooth. When the kneading force is applied, the tensile stress will occur in the metal. As the tensile stress reaches the limit of tensile strength, it will split along the direction of the effective force.

C fracture: the metal is placed between two yuan surfaces with teeth. When the bending stress reaches the bending strength limit of the material after the kneading force is applied, the metal is broken.

D impact crushing: metal is broken by the impact of high speed rotation. This method can be terminated in a number of ways. Since the application of force is instantaneous, the deformation cannot extend to all parts of the object, and only a considerable part of the stress occurs at the impact point, breaking along the internal microscopic crack. Therefore, the crushing effect of dynamic load is much larger than that of static load.

Grinding: the metal is placed between two relatively moving working surfaces, and the pressure and shear force are applied together. When the shear stress in the metal reaches its shear strength limit, the metal is broken.

In fact, all kinds of shredding machine in the process of crushing metal, are the result of several crushing methods. However, there must be one or two methods of application of force, and other crushing methods. Because the physical and mechanical properties of various metals are not the same, so the shredding machine force method should be consistent with the mechanical properties of metal, talent to achieve a good crushing effect. All kinds of hardness of metal choose impact crushing or cooperation to break more appropriate, such as grinding broken, machine wear serious; For brittle metals, it is more advantageous to choose chopping, bending and crushing. If the metal is damaged by grinding, the fine powder in the metal will increase. For the greater resistance and viscosity of the choice of metal grinding and chopping method is more appropriate.
