With the improvement of construction sand standard and the increasing shortage of natural sand resources, mechanism sand has become the main source of aggregate for modern engineering construction. Among many sand making equipment, roll crusher stands out with its unique structural design and high efficient crushing performance, especially in the sand particle shape control, grading optimisation and environmental protection and energy saving. This article will comprehensively analyse the core value of roll crusher from three aspects: technical principle, sand making effect and practical application cases. I. Principle of sand making technology of roll crusher The roller crusher consists of two rollers installed parallel to each other. And the surface of the rollers can be designed as toothed, grooved or glossy according to the demand. Its core working principle is the combination of ‘laminar crushing’ and ‘selective crushing’: 1. Squeeze Crushing: After the material enters the gap between two rollers, it will be squeezed and crushed through the relative rotation of the rollers, and the crushing force can be precisely controlled by adjusting the roller distance; 2. Shear grinding: the texture of the roller surface produces shear effect on the material, reducing the phenomenon of over-crushing; 3. Self-cleaning design: non-crushed materials…

What Are The Conditions That Roll Crushers Need To Replace Roll Skins? Roller crusher wear parts roll skin replacement standards need to be integrated wear level, equipment operating status and production results and other aspects of judgement, the specific criteria are as follows: Roller skin wear degree 1. Thickness reduction: when the roll skin wear reaches 20%-30% of the original thickness, it needs to be replaced. For example, the original thickness of 100mm roller skin, the remaining thickness of less than 70-80mm should be considered for replacement. Some manufacturers recommend measuring the remaining thickness below the minimum allowable value (such as 60mm) need to be scrapped. 2. Surface damage: If the surface of the roll skin has obvious depression, cracks, flaking or hardened layer off, it should be replaced in time. Such damage will lead to uneven crushing of materials and accelerate the wear of equipment. Decrease in production efficiency and quality of roll crusher 1. Decrease in crushing effect: If the particle size of the material is uneven, dust increases or the output decreases significantly (e.g. the output decreases by more than 20%), it indicates that the roll skin is worn out seriously and needs to be replaced. 2….
