In March 2021, HAZEMAG received an order from for the delivery of a HAZEMAG Roller Screen HRS 2665 and a Center Sizer HCS 0830. With its unique and sometimes problematic characteristics, mined phosphate with clay inclusions will be processed by Hazemag knowhow and technology.
The Roller Screen will be fed with a feed size of up to 660 mm at a feed rate of 2,220 t/h and scalps the material at 50 on the first 3 decks and 125 mm at the 4th deck. The HAZEMAG Roller Screen with a width of 2.6 m and an overall shaft center distance of 6.5 m is equipped with Chain-Link-System, 3 Tier form-fit bows and a special scraper system on all 20 solid core shafts.
The steps in between individual modules improve the screen efficiency as it increases the material movement.
The Chain-Link-System reduces the stress into the drive system and eliminates the need for chain tensioning. The special scraper system is adjustable, and the replaceable scraper blades are made of carbide metal, which allows for handling of sticky material.
The Center Sizer with a roll diameter of 800 mm and a roll length of 3 meters, is designed for 757 t/h.
The HAZEMAG Center Sizer 0830 is equipped with intelligent crushing tools as well as adjustable and exchangeable scrapers. These special HAZEMAG design features allow for handling of sticky material.
The feed material is crushed from 150 mm to < 50 mm without any restriction.
In addition, the sizer is equipped with a roll locking device and a track roll lifting device.
With the roll locking device all HAZEMAG crushing rolls can be fixed in position for safe maintenance. This roll locking device is integrated into the crusher interlocking system. The track roll lifting device is a system that easily permits and transports the sizer out from under the feed hopper; thus, permitting full access to the sizer and its internal parts.
