Tropical and subtropical mining areas have long rainy seasons, and continuous rainfall leads to high moisture and viscosity of raw ore and stone materials. Wet materials are easy to agglomerate and adhere to equipment inner walls, causing frequent blockage of crusher cavities, screen holes and conveying chutes. Seasonal blockage problems lead to production shutdowns, reduced output and unstable product quality, becoming a major seasonal bottleneck restricting mine annual profits.

Aggregate raw materials such as limestone and river pebble contain surface soil and weathered layers, which are more likely to stick and block in rainy days; metal ores such as iron ore and copper ore contain fine mud impurities, which will agglomerate after absorbing water, resulting in unsmooth material transportation and reduced crushing efficiency. Traditional production lines have no targeted anti-blockage design, unable to adapt to rainy season wet material processing.

SMP full set of rainy season anti-blockage production technology is tailored for wet material working conditions. It is equipped with material pre-drying and pre-screening devices to remove surface moisture and fine mud in advance; the optimized anti-blockage crushing cavity structure reduces material adhesion; the self-cleaning screen mesh and vibrating device avoid screen hole blockage; the sealed conveying system prevents material damp and agglomeration.

This systematic anti-blockage solution completely solves the production difficulties of wet and sticky materials in rainy seasons, ensures continuous and stable operation of aggregate and metal ore production lines in rainy weather, avoids seasonal production stagnation and order loss, and guarantees full-year stable output and profit of mining projects.
