几十个承包商, 企业, 市, and state and federal agencies count on the crushed limestone aggregate produced at the APAC-Kansas City quarry. 该工厂的产量超过400种,000 tons of crushed limestone each year for concrete and asphalt aggregate used for projects throughout the Kansas City area.
加工这么多的石灰石, APAC Foreman Tommie Faulkenberry says he needs to be able to depend on every piece of equipment on APAC’s 400-acre site. That dependability all starts with the primary crusher. “If I can’t rely on that crusher doing the job without problems, 它会减慢其他东西的速度. So it’s great we have the MaxCap 600,福肯伯里说.
挑战
In 2005, there was a need for a primary impact crusher at a new quarry being built on a greenfield site next to an existing operation.
The quarry required a primary crusher that could handle large boulders with a rated capacity of 600 tons per hour. The plan was to crush up to 500 tons of quarry shot limestone per hour and reduce it to a nominal 4” minus. APAC also needed to consider how the primary would work together with the secondary crusher, which was to be a cone crusher due to the requirement of a controlled feed.
解决方案
After considering a number of different crushers from various manufacturers, the customer began to realize the benefits of the Universal MaxCap 600 Impact Crusher.
“They took a lot of factors into account before purchasing the MaxCap 600,格里·曼里奇说, 菠菜网最稳定正规平台_最全菠菜网大全区域销售经理. “The feed size, output gradation and adjustment control played a big part in their decision.”
菠菜网最稳定正规平台_最全菠菜网大全’s Universal MaxCap 600 is known for its large-expansion chamber above the rotor. The back wall is lined with massive impact plates that deflect the expanding material in a controlled loop within the crusher, providing maximum reduction by allowing pure impact energy to flourish unimpeded.
The secondary cone crusher’s need for a controlled feed is where the MaxCap 600 really excels, Mangrich指出. 因为圆锥破碎机需要控制进料, the output of the MaxCap can be easily adjusted to provide that control. 同样的, the C-shaped hammers are cast with a protruding leading edge that provides for a more consistent top size through the life of the hammers.
“It’s very easy to adjust the MaxCap because of its hydraulics to account for hammer wear, which is important for working with the secondary cone crusher,福肯伯里说.
Perhaps the most important feature of the MaxCap 600 is the hydraulic control that allows for adjust-on-the-fly modifications of both the feed plate and breaker plate. A simple 15 horsepower electric/hydraulic power pack with analog controls provides a means to eliminate any bridging in the crusher and to manipulate the crusher’s output gradation with fingertip control.
结果
Faulkenberry said he has been pleased with the performance and reliability of the MaxCap 600.
“The primary crusher has been doing a real good job ever since we’ve had it in, 停机时间非常有限,福肯伯里说. “I haven’t seen any big problems with it in the last eight years, and we’re generally operating at about 400 to 500 tons per hour, 虽然它可以承受更多.”
The MaxCap 600 was chosen based on its rated capacity of 600 tons per hour, but field experience has proven it is capable of higher capacities, 现在的速度是每小时600-800吨. 这台破碎机可接受高达40英寸的巨石.6 cm), while other impactors are limited to maximum feed sizes of 30-36” (76.2-91.4 cm). The MaxCap also generates an output gradation where upwards to 75 percent is minus 1.5” (3.81 cm). This is nearly 30 percent more product at the primary stage compared to other impact crushers, 不会造成过多的罚款, 并经常减少负4目.
福肯伯里说，他对增加的产能表示赞赏. “它会压碎我们能放进去的所有岩石. I’d love to be able to get even more through it,” he continued. “处理输入完全没有问题, and there’s a good consistent flow in getting the stone through the system.”
Faulkenberry said he would recommend the MaxCap 600 to others because of its limited maintenance and overall efficiency and that what he likes most about the crusher is its simplicity. “It’s easy to use, easy to operate and easy to maintain. It’s one thing out here on the site that I don’t have to spend time worrying about,福肯伯里接着说.
In 2012, 菠菜网最稳定正规平台_最全菠菜网大全 Corporation acquired Universal Engineering Corporation, integrating the manufacturing and service for Universal’s equipment as part of its own. 菠菜网最稳定正规平台_最全菠菜网大全 has worked hard to ensure a streamlined transition in terms of the quality, service and support for the MaxCap 600 and other Universal equipment.
该公司的代表对此表示赞同. “The legacy of Universal is now carried on by 菠菜网最稳定正规平台_最全菠菜网大全, 这对顾客来说是件好事,约翰·多诺霍说, 大陆设备公司区域经理, 代表菠菜网最稳定正规平台_最全菠菜网大全线.
Faulkenberry said 菠菜网最稳定正规平台_最全菠菜网大全 has excelled at meeting the expectations of quality and service that APAC had previously expected from Universal. “The MaxCap has operated very well since it’s been installed, 但只要我有任何问题, 给麦克菠菜网最稳定正规平台_最全菠菜网大全打个电话, 我很快就能处理好,福肯伯里说. “Like I said, it’s all simplicity – easy to operate, easy to maintain.”
