The new Joy HRX 1000 is a hard rock sizer designed to push the envelope on where sizers can be successfully applied.

According to Komatsu, a high-capacity and compact package make the HRX 1000 a choice for hard rock underground or mobile applications. Utilizing Joy pick technology, the HRX 1000 is designed to cut through abrasive materials that traditional sizers cannot. Having been used in an installed base of more than 10,000 pick-utilizing machines, including feeder breakers, longwall shearers and continuous miners, Komatsu says Joy pick technology has evolved to deliver the productivity customers are looking for in a variety of environments.

With the introduction of the new HRX 1000, Komatsu expands its product offering of primary and secondary sizers.

“There are several different types of crushers, and each has its merits,” says Charles Anderson, director of crushing systems at Komatsu. “Sizers have been successful for many customers because they perform well where other types of crushers struggle. The HRX sizer is designed to crush harder, abrasive minerals, while providing all the benefits inherent to sizers: fines reduction and the ability to pass muddy, sticky material with no over-crushing.”

Komatsu says it recently entered into an agreement with Metso Outotec to provide sizers for its stationary and mobile crushing stations. The first project involved the installation of a Joy HRX 1000 on the Metso Outotec Lokotrack LT1510RC track plant. Komatsu says the sizer is crushing minerals used for cement production ranging from wet and sticky to hard rock.

“The first HRX 1000 sizer has been operating at a cement plant in Thailand and has been working well, crushing a variety of mineral feed to include grey, black and brown shale,  limestone, andesite and overburden, says Julius Mäkelä, vice president of mid-size and mobile crushers at Metso Outotec. “In Thailand, the feed can change from dry to saturated, and the HRX 1000 can deal with these variations, broadening the range of applications where sizer-based Metso Outotec Lokotrack mobile units can successfully be used.”
