Description

A high-efficient roller skin structure for roll crusher

Technical Field

The utility model belongs to the technical field of the roll shell of roll crusher, concretely relates to a high-efficient roll shell structure for roll crusher.

Background

The double-roller crusher is crusher equipment applied for hundreds of years, is famous because a main crushing part of the double-roller crusher consists of two rollers, has a simple structure, can perform medium and fine crushing on medium and hard and soft ores, and has the advantages of fine crushing granularity, high processing capacity, simplicity in operation, long service life, adjustability of discharging granularity and wide application range.

The double-roll crusher mainly adopts a triangular belt or a universal joint coupler to transmit and adjust a gap between two rolls, uses a spring or a hydraulic cylinder to control the pressure of the rolls, and utilizes the two rolls to extrude materials to crush. The material falls into between two rollers through the feed inlet, and the finished product falls down naturally after the pair roller extrusion breakage, when meetting the too hard or can not the broken material, the roller can rely on the effect of pneumatic cylinder or spring to let and let off automatically, makes the clearance between the two rollers increase, and the too hard or can not the broken material falls down naturally to this guarantees that the machine is not destroyed. The surface of current roller (roller skin) all is equipped with outside bellied lug for improve the crushing ability to the material, however, at actual broken in-process, often can meet the material jamming in the condition of space position between adjacent lug, perhaps can be because the material has certain viscosity, and lead to the material can't break away from the roller skin surface, when the roller skin is rotatory a week, can influence the crushing efficiency to the material, cause unnecessary time consumption.
