Frame Construction Series Jaw Crusher

In the realm of crushing equipment, the Frame Construction Series Jaw Crusher stands out as a reliable and high - performance solution for primary crushing operations. This type of jaw crusher, with its unique frame construction, has been engineered to handle the toughest feed materials, making it a favorite in industries such as aggregate production, mining, recycling, and industrial minerals processing.

Pinned and Bolted, Non - Welded Frame Construction

1.Exceptional Durability

The core feature of the Frame Construction Series Jaw Crusher is its pinned and bolted, non - welded frame. This construction method offers several advantages over traditional welded frames. By using pins and bolts to assemble the frame components, the crusher can withstand high levels of stress and fatigue. Welded frames, over time, may develop cracks due to the continuous vibration and impact during the crushing process. In contrast, the non - welded design of these jaw crushers distributes stress more evenly, significantly reducing the risk of structural failure. For example, in a large - scale quarrying operation where the crusher is in continuous use, the non - welded frame ensures long - term reliability, minimizing unplanned downtime.

2. Easier Maintenance and Repairs

Another benefit of the pinned and bolted construction is the ease of maintenance and repairs. In case a particular frame component is damaged, it can be easily removed and replaced without having to worry about complex welding procedures. This modular design approach allows for quick and cost - effective repairs. For instance, if a side plate of the frame is worn out, technicians can simply unbolt the old plate and bolt on a new one. This not only saves time but also reduces maintenance costs, as it eliminates the need for specialized welding equipment and skilled welders.

3. Superior Fatigue Strength

All the frame components of the Frame Construction Series Jaw Crusher are casted using a specially developed alloy. This alloy is designed to have excellent fatigue strength, which is crucial for withstanding the repeated impact and vibration during the crushing process. The cellular, honeycomb - like structure within the frame further enhances its strength and durability. This unique structure, similar to that found in nature, provides additional support and reinforcement, ensuring that the crusher can operate under harsh conditions for extended periods.

High - Performance Crushing Capabilities

1. Aggressive Pitman Motion
The Frame Construction Series Jaw Crushers are equipped with an aggressive pitman motion. The kinematics of the movable jaw dies are carefully optimized to maximize the crushing performance. The stroke of the movable jaw is amplified from top to bottom, being at its longest in the lower parts of the cavity. This design principle has several advantages. Firstly, it increases the open area between the jaw dies, allowing the material to have more space to move and get out, which in turn boosts the capacity of the crusher. Secondly, it enables inter - particle crushing, where the materials being crushed collide with each other, further enhancing the reduction ratio. As a result, these crushers can efficiently break down large rocks into smaller, more manageable sizes.

2. Excellent Material Intake
These jaw crushers are designed with a larger feed opening, which significantly increases the material intake capability. This ensures that rocks can enter the crusher's cavity without any restrictions. Additionally, the steep nip angle of the crusher's cavity cross - section plays a crucial role. It decreases operating costs by reducing wear on the jaw dies. The steeper angle also speeds up the material flow down the cavity, contributing to higher production rates. For example, in a mining operation where large boulders need to be processed, the large feed opening and efficient material flow allow the crusher to handle the high - volume intake of raw materials effectively.

Wide Range of Applications

1. Aggregate Production

In the aggregate production industry, the Frame Construction Series Jaw Crusher is widely used as a primary crusher. It can process a variety of rocks such as limestone, granite, and basalt. The ability to produce consistent - sized aggregates is essential for applications like concrete production, road construction, and asphalt manufacturing. The crusher's high - capacity and efficient crushing capabilities ensure a steady supply of high - quality aggregates, meeting the demands of large - scale construction projects.

2. Mining Operations

For mining operations, whether it's surface mining or underground mining, these jaw crushers are ideal for primary crushing of ores. They can handle the toughest minerals, breaking them down into smaller pieces for further processing. In a gold mining operation, for example, the Frame Construction Series Jaw Crusher can initially crush the gold - bearing rocks, making it easier to extract the valuable minerals in subsequent processing stages.

Recycling Applications

In the recycling industry, especially for materials like concrete and asphalt, the Frame Construction Series Jaw Crusher plays a vital role. It can break down these recycled materials into reusable aggregates. This not only helps in reducing waste but also provides a cost - effective alternative to virgin materials. The crusher's ability to handle a wide range of feed materials, including those with impurities, makes it suitable for recycling applications.

Installation and Operational Advantages

Simple Installation

The modular design of the Frame Construction Series Jaw Crushers makes installation a breeze. They can be installed within a few days, minimizing on - site engineering and fabrication requirements. This is particularly beneficial for both new plants and when replacing old jaw crushers. The integral motor base, which is a standard feature in many models, reduces space requirements and allows for the use of standard flywheel guards, eliminating the need for local engineering and fitting. In some cases, the crusher can be transported in pieces, further simplifying the installation process, especially in remote or difficult - to - access locations.

Easy Operation and Maintenance

These jaw crushers are designed with the operator in mind. They are easy to operate, with intuitive controls that allow operators to adjust settings such as the discharge opening width. The components and parts that require regular renewal are engineered to be easily accessible. For example, the jaw dies, which are subject to wear, can be quickly replaced. Some models also come with optional features like automated lubrication systems, which further reduce maintenance efforts. This ease of operation and maintenance ensures that the crusher can be up and running with minimal downtime, maximizing productivity.

The Frame Construction Series Jaw Crusher, with its innovative pinned and bolted, non - welded frame construction, high - performance crushing capabilities, wide range of applications, and installation and operational advantages, is a top choice for industries that require reliable and efficient primary crushing equipment. Whether it's in aggregate production, mining, or recycling, these jaw crushers have proven their worth in thousands of installations worldwide, delivering maximum productivity at the lowest operating costs.
