SAFE AND DURABLE OPERATION The screening process is just as important as the crushing itself. Screens are the heart of every rock processing plant. They are used to classify materials both in different stages of the crushing process and in final product separa tion.
C. Refer to Guideline for Safe Operation of Mobile Plant in Surface Mines and Quarries. 2.0 PRIMARY STOCKPILES A. Live stockpile accident are all too common. The limits of safe tipping areas change as material is loaded out, and operating rules
SCREENING The first unit operation generally encountered in wastewater treatment plants is screening. Screening removes larger materials and coarse solids from raw wastewater metals to prevent damage and clogging of downstream equipment, piping, and appurtenances. Two types of screening processes: Manual. Automated.

The efficiency of the screening operation depends of the spacing between screen bars: Fine screening, for a spacing under 10 mm; Medium screening, for spacing of 10 to 40 mm; Coarse screening, for spacing of over 40 mm; Usually the fine screening is preceded by a preliminary screening operation for purposes of protection.
A reliable and efficient mobile crushing plant is the sum of several factors working together smoothly. The ® C120 jaw crusher with its large feed opening provides excellent capacity even in the toughest applications. The hydraulic drive ensures trouble free operation and enables the crusher direction to be changed in case of blockage.
