The SEPOR Mini-Jaw Crusher is suitable for crushing small quantities of rock and other friable material, ranging in hardness from hard quartz to relatively soft claystone. It is available with a variety of wear surfaces:

Hardened steel alloy plates for users not concerned with iron contamination and 85% Alumina (Ceramic) for those who can not tolerate iron contamination.

A tungsten carbide model is also available, which is the hardest material of the three. The tungsten carbide contains 6% cobalt as a binder.

All jaw plates types are interchangeable.

The feed opening is 2″ x 2″ with a maximum feed partical size of -1″ material. About 1/3 lb. per minute (20 pounds per hour) can be crushed to -1/8″ depending on the nature of the feed material. The size of the crushed product is adjustable by turning the handwheel, which adjusts the gap at the bottom of the jaws. The jaw opening range is from 1/4″ to 1/16″. However, the finer the crushed product, the lower the throughput.

A stainless steel tray collects the crushed sample. If cross sample contamination is of paramount importance, each sample may be caught on separate trays.
