IKOBearing iron alloy cage due to resistance“amplexation”Poor performance，Cant rotate at high speeds。The wear is sensitive and there“amplexation”At danger，Copper alloy cage should be used。Generally pressed cages are made of phosphor bronze，The cage is made of high strength brass。High strength brass has good wear characteristics，It can be cast or forged，The machining performance of the car is good，It is easy to produce high roughness pocket surface and guide surface。 Copper and steel are low friction pairs，And the copper is resistant to corrosion、Wear and chip drop are less，Made byIKOHigh reliability of bearing solid cage，This class
Working principle The material enters the crushing chamber from the hopper through the screw conveyor，It is cut and shredded by a high-speed rotating blade，The material is transported into the cyclone by the method of negative pressure air transport、Bag type dust collector，Discharge material to meet product requirements。 Main use Local host、Auxiliary engine、The electric control box consists of three parts。With wind selection、screenless、netless、Uniform particle size and other properties，The production process is continuous。The machine has reached the international advanced level，It is widely used in pharmaceuticals、Chemical engineering、Material crushing in food and other industries。 Technical parameter Model number

one、The effect of sawing Cut through metal materials with a saw blade（Or job）Or the operation of cutting grooves on the workpiece is called sawing。 Although the current various automation、Mechanized cutting equipment has been widely used，But hairsaw cutting is still common，It has convenience、Simple and flexible features，In single piece small batch production、Cutting irregular workpieces at temporary sites、notching、Dressing and other applications are widely used。Therefore, manual sawing is one of the basic operations that fitters need to master。 Sawing work scope includes： （1）Divide various materials and semi-supplies； （2）Saw off excess parts in the work

Precautions for using electric vehicles 1、Vehicle in operation，never“advance、retrogress”The direction switch is mistaken for the turn switch。Unless you need to slow down，Otherwise, do not press the brake pedal directly to the end。During the operation of the vehicle，When the battery is low（Can be through the electrical meter、Power failure lights and other alarm devices are obtained），Charge the battery as soon as possible，Prevent battery overdischarge。 2、In the use of electric vehicles, special attention should be paid to the timely charging of the battery and the correct maintenance of the battery。Pay attention to the method when charging the battery，It is necessary to store electricity
