a•  Pollution handling capability; high effective sand out purification: over;

b•  Failure ratio of simple operated oscillating screen is low and its installation, operation and maintenance is convenient;

c•  Slag materials screened by advanced straight-line oscillation have a very good dewatering efficiency;

d•  Adjustable exciting force of oscillating screen, face and mesh size can make the system to have a good screening efficiency in all strata;

e•  Screening efficiency of oscillating screen is so high that a kind of all drillers can bore and feed in various strata;

f•  Energy saving efficiency is significant because the power factor of oscillating motor is high and power consumption is low;

g•  Low operation noise of oscillating screen is favorable to improve the working condition;

h•  Abrasion and corrosion resisting centrifugal mud pump (slag mortar pump) has the following advantages: advanced construction, highly level commonality, reliable operation, convenient assembly and dismount, simple maintenance etc. The thicker abrasion resisting parts and the balance-type support can make the pump to convey the strong corrosive and abrasive, high concentration slag mortar;

i•  The hydraulic cyclone with advanced construction parameter has an excellent mud and sand-sorting index. The corrosion and abrasion resisting and the lightweight of cyclone material can run in the worst condition without maintenance and has the following features: convenient operation and adjustment, economic and durable;

j•  The new fluid level automatic balancing device can not only hold the stable fluid level of mud reservoir, but also handle mud repeatedly in order to increase purification quality further;

k•  The unique recoil device can prevent mud reservoir from silting and flooding in order to run normally and long term;

l•  In the part of electric control, the logical control system of electric relay is adapted with simple wiring, strong capability of anti jamming and convenient maintenance.
