Abrasion Causes of Roller Shell for Double Roll Crusher

The roller shell of double roll crusher influenced by the material impact, self-weight and other combined forces, is easy to wear, and the roller shell abrasion will not only affect the work efficiency of roller crusher, also cause the harm to other roller crushing machine parts. Only the roller shell of double roller crusher is in good condition, the crusher can obtain the high production capacity. Due to the importance of roller crusher skin, we need to timely know the factors that cause the roller shell wear and do the corresponding adjustment when it is seriously worn.

The roller shell abrasion in double roller crusher is mainly related to the following factors:

1.The material is too hard and too big

Double roller crusher is suitable to coarsely and intermediately crush the nubby brittle material with the compressive strength no more than 150Mpa, and its feeding particle size is determined according to different equipment models. If the compressive strength, hardness and granularity of the material exceed the acceptable range of double roller crusher, it will cause the serious wear and tear on the roller shell.

2.The material of double roller crusher shell is inferior

The roller shells of roller crusher are directly in contact with material. If they are made of the undesirable materials without eligible abrasion resistance and toughness, there will be the serious wear on the roller shell, and the production efficiency of roller crusher will be reduced.

3.The roller shell material is not selected properly

The roller shells with different materials need be used to crush the different materials and have different crushing effect. For example, the grey cast iron roller shell is mostly installed in the roll crusher for ordinary and coarse crushing, mainly for crushing the argillaceous raw materials; The impact resistance of multi-alloy cast iron roller shell is poor, so it can be used to crush the low-hardness raw materials for the fineness check and plasticizing function; High chromium composite roller crusher skin, its outer layer is made of high chromium alloy and the inner layer is made of ductile iron, which is mainly installed in fine crushing double roll crusher. If the improper material is used to make roll shell, and then the roller shell is installed in the roller crusher, it will definitely increase the roll crusher shell wear, will not achieve the corresponding crushing effect, cause the waste of manpower and material resources.

4.The size and surface shape of the roller shell and crushing roller of roller crusher are not fit

Some unprofessional double roll crusher manufacturers do not pay attention to the specifications such as the size and shape when producing equipment and process the roller shell and roller together blindly, as the result, the roll crusher equipment cannot play its expected crushing effect, increasing the roller crusher shell wear. Or, when the user replaces the roller shell, it cannot be purchased according to the size or shape of the original equipment, the roller shell and roller are not matched, thus causing the serious wear on the roller shell of double roller crusher.

5.Uneven material feeding

If the feeding speed id too fast, it will increase the roll crusher load; If the feeding speed is too slow, which will cause the equipment to be idled. Both of two situations can cause the excessive wear and tear of the roll crusher shell.

The roller shell of HXJQ double roll crusher and toothed roll crusher is made of the anti-wear high manganese steel and Hongxing Machinery adopts the special technology to strengthen the working hardening layer of roll crusher skin to increase its density, hardness and wear-resisting property. In the selection of roll crusher skin, for crushing the materials with different hardness, we use the Mn13Cr2, Mn13Cr2MoNi, Mn18Cr2, Mn18Cr2MoNi and other materials to process the roller crusher skin, HXJQ technical personnel combine it with the corresponding roller in accordance with the specifications of the roller crusher skin, so as to have the perfect cooperation of the roll crusher parts, ensure the standard production of double roller crusher and meet customer's product quality requirements. If you have needs on stone crusher (jaw crusher, cone crusher, impact crusher, double roll crusher, hammer crusher, etc.), welcome your inquiry! We are always ready to cooperate with you.
