Coarse Material Washers

Effective Washing Of Natural And Crushed Materials

Coarse material washers are used to remove a limited amount of dirty material from a coarse aggregate. This material includes very water soluble slimes, silts, soft clay, and organic particles. They are often used as a final wash following a wet screen and are designed to scrub and clean gravel and crushed stone up to 75mm (3’’) in size. Both single and double spiral units are available depending on the capacity required.

Features

Capable of producing high capacities, coarse material washers deliver extreme productivity.

High efficiency single or dual drives result in low power requirement, thus reducing operating costs while increasing throughput.

Outboard LBA mnimizes or eliminates water and material contamination of the bearings due to seal wear.

Oil lubricated heavy duty gear box

Heavy duty steel plate construction provides years of operation

Available in both single and twin screw configurations.
High efficiency single or dual drives result in low power requirement, thus reducing operating costs while increasing throughput. A large capacity pool and adjustable speed control via sheave changes ensures a steady and consistent flow of fine aggregate products.

Features and Benefits

The high efficiency V belt drive assembly reduces power and maintenance requirements resulting in increased life and reduced operating costs.
– Remove dirty materials
– Oil lubricated heavy duty gear box
