What is a roller crusher? Roller crusher (also known as double-roller crusher, roller sand making machine) is a kind of mechanical equipment to achieve crushing through two oppositely rotating rollers to squeeze the material, mainly used for medium and fine crushing of medium-hardness materials (such as limestone, coal, pebbles, etc.), is widely used in the cement, metallurgy, chemical industry, electric power and building materials and other industries. 1. Core structure and working principle Basic structure Roller: the core working part, divided into fixed rollers and movable rollers, the surface can be designed as smooth or toothed (toothed roll crusher), the material should be wear-resistant. Adjustment device: Adjust the gap between the two rolls (0.5-50 mm) by wedge or shim to control the granularity of the material (e.g. if the wedge is moved up and the gap is increased, the material will become coarser). Driving system: double motor drive, through the triangle belt to drive the roller reverse rotation, some models are equipped with hydraulic spring overload protection device. Auxiliary components: support bearings, safety cover, iron removal device (to prevent damage to the roller by metal foreign objects). Working Principle The material falls into between the two rollers from the inlet,…
Roll Crusher High Humidity Material Solution Roll crusher is prone to sticking rollers, clogging, uneven discharging and other problems when dealing with viscous materials (such as clay, wet coal) or materials with high moisture content (moisture content >15%). The following are the specific operation techniques and optimisation solutions combined with industry practice: 1. Pre-treatment and feed control Moisture regulation and control Drying pre-treatment: For materials with moisture content > 20%, priority is given to drying equipment (such as drum dryer) to reduce the humidity to less than 15%. Mixing of wet and dry materials: Mix wet materials with dry materials (e.g. dry coal, limestone) in the ratio of 1:1~1:2 to reduce the overall viscosity. Heating assistance: add hot air device (temperature 80~120℃) at the feeding port to evaporate the surface moisture and reduce the adhesion. Optimisation of particle size and feed Pre-screening: Pre-screen the large materials (>300mm) to avoid jamming or roller gap extrusion splash. Uniform feeding: adopt frequency conversion feeder to control the flow rate, avoid instantaneous overloading and blockage (suggested feeding speed ≤ 80% of the rated value). 2. Equipment parameter adjustment Roll gap and pressure adjustment Expand the roller gap: for high viscous materials (such as plasticity…
