| MAGOX® BLOCK GRADES
PROMOTE UNIFORM BLOCK HARDENING Poured feed blocks---also known as molasses blocks, chemical blocks, reacted blocks, and liquid blocks---offer cattle feeders and dairymen the advantages of convenience, reduced feed wastage, weather resistance and controlled consumption while providing animals with a nutritionally balanced supplement. They require no energy intensive presses that are needed to make compressed blocks, which can be an advantage to the manufacturer. The end user does not require any special feeding or handling equipment, since self-setting blocks can be fed on a floor or on the ground. The manufacturing processes for most poured blocks on the market are covered by patents or are licensed to other feed companies. While many formula variations exist, most blocks marketed in the USA are one of three or four basic approaches. Some formulas are cooked or dehydrated while others require only mixing and pouring. Several of these block manufacturing technologies utilize magnesium oxide in the hardening process. However, not all magnesium oxides are effective for block hardening. Slowly reactive MgO sources can result in inadequate curing while unpredictable sources can result in undesirable variation in block hardness. Blocks that are too soft can lead to over-consumption. This can be a serious problem when the formula contains non-protein nitrogen, since gross over-consumption can lead to ammonia toxicity and even death. Blocks that are too hard may not permit adequate intake. The process ideally requires a finely ground magnesium oxide with a high and consistent rate of reactivity. MAGOX® 93 HR -325 AND MAGOX® 98 HR FULFILL THESE REQUIREMENTS. They are widely used in the United States as block hardening agents for self-setting blocks. MAGOX block grade products are produced only in multiple-hearth furnaces under carefully controlled temperatures which results in uniform reactivity that is needed for uniform block hardening. Every lot must meet high standards of reactivity and purity before shipment. Highly reactive magnesium oxide is subject to a gradual loss of activity when exposed to moisture. The exposed MgO surfaces gradually hydrate to form magnesium hydroxide. For this reason, MAGOX should be stored in dry conditions. It is recommended that products be used within six months for optimal activity and performance. MAGOX 93 HR -325 AND MAGOX 98 HR ARE ESPECIALLY DESIGNED FOR USE IN SELF-SETTING FEED BLOCKS. ©2007 by Premier Chemicals |
