Dewatering Screen and Hydrocyclon

A dewatering screen is an apparatus primarily used in mining, aggregate processing, and recycling industries for ridding water from sand, gravel, and other solid materials. This becomes necessary in removing water from a substance to reduce the moisture content so that it can be handled and transported with ease, processed further, or even possibly stored. It operates on high-frequency vibrations, which drive out the water from the screens, leaving the solid material at the surface of the screens. The material is conveyed along the vibrating screen deck and the expelled water separates away, leaving a drier, more manageable product in its wake. The ability of dewatering screens to perform moisture control is essential for the effectiveness of many industrial processes. Preparing sand for the production of concrete, or ore for further processing after mining, will require guaranteed moisture content of the material.

The bucket washer/dewaterer is specialized machinery used in agriculture, food processing, and recycling industries for cleaning and separating materials. It features a rotating drum or a series of buckets that dips in the water, agitating the materials to free them from dirt and debris, and lifts them out of the water for dewatering. These effectively wash the materials, dewater them for further processing or packaging. Bucket washers/dewaterers have gained prominence in the production of fruits, vegetables, nuts, and any other small, solid products that require washing effectively and drying prior to processing or resale to the consumer.

Filter press systems are equipment used in separating solids from liquids in various industrial processes. The system includes a series of filter plates arranged in a stack within a filter press unit. The plates are normally covered with filter cloth or filter medium that will allow the liquid component to pass through while holding back solid particles. During the process of filtration, a slurry or suspension is typically pumped into a filter press, where pressure is applied that squeezes the liquid component through the filter media, leaving solid particles trapped within the filter cakes. Afterwards, these cake solids are discharged from the filter plates, and the clarified liquid is discharged at the end of a filtration process to have efficient separation and dewatering of the solids from the liquid phase.

The Rake Thickener System is what equipment is commonly used in industries for thickening slurries or suspensions through separating them from solids by means of apparatus. Usually, it will have a tank or a basin where slurry shall be introduced, with a mechanism that provides movement similar to the rake arm or blade, which rotates slowly in the tank. The rake arm travels through the slurry, picking up settled solids from the bottom of the tank and moving them very slowly towards the center for removal. Continuous rotation of this rake arm facilitates the effective concentration of solid particles in slurry, finally separating a thickened underflow from a clarified liquid overflow.
