Ring die pellet mill as one of the most important parts, it is good or bad can be said to directly determine the function and life of the machine. In the purchase, we can determine how its performance and service life of the length of it. Let us look at what factors determine it:. A wear: Most ring mold damage is due to wear. Die back caused by the use of increasing surface wear and die orifice, its wear resistance as its surface hardness, microstructure and chemical composition vary. It is mainly made of a material and heat treatment method is determined; B corrosion resistance: certain additions under high temperature and high pressure can cause pitting, corrosion thereby stamper material. Corrosion is the most critical factor affecting the performance of the die, high carbon, high chromium die has the best corrosion resistance; C Toughness: die during granulation under tremendous impact, can cause die timely damage; over working hours also cause fatigue damage die. Material selection stamper, heat treatment methods, the opening ratio is an important factor affecting toughness. The relationship between the three: A wear resistance and toughness: improving hardness can enhance the wear resistance of the die, but will reduce the toughness of the stamper, to increase its brittleness, and therefore must be limited to maintain the hardness of the stamper using the Structurally minimum required level B. abrasion, corrosion resistance and toughness: metal structure and poor corrosion resistance difference stamper reduces wear resistance, impact resistance is poor stamper, relatively easy to crack C. toughness and opening rate: the rate of increase may lead die openings easy to crack D. Therefore: To compromise use of these factors to select the ring mold. Ring die pellet mill Changzhou, Changzhou particle machine accessories www.rtjxjg.com
