The recent CONEXPO show in Las Vegas saw McLanahan Corporation announce some key developments in its mining technology offerings covering primary and secondary crushing, filter presses and thickening. The company says it has “collaborated with customers to fully understand their needs when it comes to primary crushing and the new designs are the result of that research. In jaw crushers, McLanahan says it has engineered its new jaw crusher line to give producers “a higher performance primary crushing solution than has ever been available before. The result is a safer, simpler and smarter jaw crusher.” A new Deep Cone Thickener has been launched to “help producers reduce or eliminate the need for settling ponds and other structures”; while the new filter press design has been further improved.
In more detail, the new jaw crusher design includes safety lock pins and hydraulic assist for wear parts change-out makes maintenance safer. McLanahan engineers also designed a simpler way to adjust close-side settings and provide tramp iron relief. Hydraulic rams are isolated from crushing action, allowing longer life and full automation, while virtually eliminating toggle migration. The attack angle and crushing stroke pattern have been engineered to increase capacity up to 15% while minimising wear on the jaw dies.
The McLanahan cone crushers are capable of secondary, tertiary and quaternary crushing. Features include top-down maintenance; safe unblocking (no need to dig out when stalled; simply press a button to open and restart when fully opened); while hydraulic overload does not damage the machine within the travel of the cylinders. Simplicity is assured by design features such as all-roller bearing design; avoiding dilution of the finished product with poor shaped material; excellent particle shape potential; simple hydraulic controls; and easy manganese changes.
The new Deep Cone Thickener will help producers do more with their existing resources and meet challenges of limited land resources. Deep Cone Thickeners achieve the highest solids concentration possible through gravity separation. They reduce the settling pond footprint, making them safer for the environment and site personnel. With no full-time operator required and rarely being designed with moving parts, they are simpler for mineral processing operations. Producers with Deep Cone Thickeners also have a smarter operation because they have control over the dewatering process and have recycled water immediately available.
Finally with the new filter presses, McLanahan says it has made significant engineering and operational improvements. These improvements are all geared toward helping producers make their operations more efficient, while eliminating the need for costly settling ponds. They include eliminating settling ponds creates a safer situation at any processing facility. The dry, easy-to-handle byproduct of filter presses can be safely handled and disposed of, as opposed to massive amounts of water that settling ponds require. Operation is made simpler by few moving parts and that the filter press does not require a full-time operator. The McLanahan filter press line has also been engineered with a single hydraulic cylinder. “Adding a McLanahan filter press to an operation is smarter because it eliminates fines and wastewater management bottlenecks” says the company.
