The latest equipment solutions in crushing, breaking

Hazemag says its exclusive and unique computer-controlled hydraulic adjustment system for impact aprons (and third crushing path) brings about many exciting features. With the HAZtronic system, impactor performance can be optimized with recipes or pre-programmed apron settings. These settings further enhance product quality and consistency, the company says. The HAZtronic system also allows users to optimize the correct apron settings with varying material characteristics within a quarry. According to Hazemag, its hydraulic adjustment system features allow for quick gap adjustments, optimum control over product size, smoother crusher operation, tramp iron protection, reduced downtime and reduced operating costs.

Cone mantle designed to better direct feed 

Columbia Steel engineers realize that sometimes it’s small design improvements in wear parts that mean notable gains in crusher performance. By looking beyond the concept of basic gravity feeding, Columbia Steel says it developed a unique cone mantle intended to direct feed more efficiently. The design can produce a higher volume of crushed product by consistently drawing material into the cone crushing chamber, Columbia Steel says. The company applies this same performance-enhancing approach to jaw and gyratory crusher wear parts. Columbia Steel engineers design crushing surfaces to improve production and product sizing, while lowering discard weight and overall operating costs. Alloys are tailored to meet the level of impact and abrasion encountered by customer equipment, resulting in better overall plant performance.

Solutions for a variety of equipment

Okada America’s 15 TOP Series hydraulic breakers range in energy classes from 150 ft.-pounds to 15,000 ft.-pounds, providing solutions for skid-steers, compact excavators, track loaders, backhoes and excavators. A large-capacity accumulator reduces pressure spikes to protect the carrier hydraulic system. Nitrogen gas cushions the piston on the upstroke, eliminating the need for shock absorbers and increasing the piston downstroke force. Also, a central grease port allows the breakers to easily adapt to most auto-lube systems. And a long stroke design reduces shock loads and vibration that can cause machine stress and operator fatigue.

Jaw series features several model options

The Pioneer jaw crusher series can deliver up to 25 percent more tons per hour than comparable units on the market, according to Astec Industries. The heavy-duty flywheels offer reduced horsepower requirements, the company says, and the stroke delivers higher capacity and increased operations. Available in four models, Astec says the benefits of the Pioneer jaw crusher series will improve efficiency and increase profits.

Elevating manganese quality through manufacturing

According to Unified Screening & Crushing, what sets its manganese apart from others is that its quality starts with a process that originates at the foundry. Unified products are inspected four to five times during the actual manufacturing process – from the heating of the material to the pouring temperatures. The number on Unified’s manganese is tracked back to the foundry, with casting deliveries coming with a commitment from an ISO-qualified foundry.
