Types of jaw crushers

The jaw crusher, also known as the tiger mouth, is one of the main crushing equipment in industrial and mining production. It is mainly used to crush various ores and large block materials into medium-sized and small pieces.

According to the structural form and working principle, there are many types of jaw crushers, such as double cavity jaw crushers, single toggle jaw crushers, and compound pendulum jaw crushers.

• Double Cavity Jaw Crusher: The crushing work of the double-cavity jaw crusher is realized by two jaw plates: moving jaw and static jaw. The static jaw forms a crusher box with an elbow plate. The materials are crushed and discharged through the weight of the material. The double-cavity jaw crusher has a higher output than the single-cavity jaw crusher.
• Single Toggle Jaw Crusher: Single toggle jaw crushers feature a swing design at the upper part of the moving jaw. It is more lightweight and simpler than its counterpart and is still widely used in various industries. Single toggle jaw crushers are used for soft and mid-hard rocks and ores; double toggle jaw crushers are used for hard rocks and ores.
• Compound Pendulum Jaw Crusher: The compound pendulum jaw crusher has the same functions as the simple pendulum jaw crusher, but its application areas are wider. The jaw crushers for sale are mostly compound pendulum jaw crushers.

Specifications and Maintenance

Specifications of Jaw Crusher PPT Presentations images may vary based on the type and model of the jaw crusher.

• Capacity: The capacity of a jaw crusher is often referred to as the amount of material the machine can break in an hour. The capacity is usually represented in tonnes per hour. According to available data, small jaw crushers have an average capacity of 1-5 tonnes per hour. Large models can break up to 700-800 tonnes per hour.
• Dimensions: Jaw crushers vary in their lengths and widths depending on the model. For instance, small jaw crushers can measure 24 x 36 inches or 20 x 30 inches, while large models can measure 42 x 48 inches. The dimension of the jaw crusher determines the space it occupies in a mining site.
• Power: The jaw crusher's power is in kilowatts or horsepower. It is the amount of energy needed to crush the stones or ore. Some crushers require as little as 15 kW, while larger ones require as much as 200 kW or more. The motor's power determines the crushing ability of the machine.
• Weight: A jaw crusher can weigh anything from 2,000 kg to over 50,000 kg, depending on its size and build. The heavy-duty construction ensures the machine can withstand the intense pressure of crushing rock.

Maintenance

Regular maintenance of a jaw crusher is crucial for its optimal performance, longevity, and safety. Here are some maintenance tips for jaw crushers;

• Regular lubrication: Ensure all lubrication points are oiled at the right time, as specified by the manufacturer's manual. Use grease and lubricating oil that are free of impurities and dirt.
• Lubrication analysis: Periodically sample the lubricating oil and analyze it for any abnormal wear signs. This can help identify potential issues.
• Safety inspection: Ensure protection and safety devices such as the guards, shut-off switches, interlocks, and emergency stops, are in good condition and working as they should.
• Regular cleaning: Remove any debris stuck to the jaw plate. Clean the frame, cross-beams, and other components of the crusher regularly to improve airflow and reduce the risk of fire.

Usage scenarios of jaw crushers

The main purpose of a jaw stone crusher is to crush huge stones into smaller pieces for further usage. With this focus, one might think that the usage scenarios for this machine are very few. But the truth is that the heavy-duty machine is used in many industries and sectors, both directly and indirectly.

While crushing stones remains the main purpose, the small stone pieces are also used in various applications in different industries. This makes the application of small stone crushers vast and varied. Here are some usage scenarios for jaw crushers and the smaller stone crushers that work with them.

• Mining Industry

  In the mining industry, jaw crushers have been the most popular crushers for a long time. Their main purpose is to break down huge and massive ores to finer and smaller pieces for further processing and extraction of valuable minerals.

• Construction Industry

  In the construction industry, stone crushers play a very important role. The crushers break down granite, limestone, and other massive rocks into smaller pieces. These stone pieces are then used in different construction applications, such as making concrete.

• Landscaping and Gardening

  Jaw crushers, along with other types of stone crushers, are used to create small stone chips and pebbles. These decorative pieces are mainly used in landscaping and gardening projects. They are also used to make walkways and garden paths.

• Agricultural Sector

  Agricultural sectors also indirectly benefit from minimizing jaw crushers. The small stone pieces produced are used to improve drainage systems in farms. They are also used to prevent soil erosion.

• Cement Manufacturing

  Cement manufacturing companies also benefit from mini jaw crushers. That's because limestone and other hard rock materials are the main raw products for manufacturing cement. After being crushed into smaller chips by the crushers, the limestone will be ground further to produce the fine cement powder.

How to choose jaw crusher PPT

Consider the following factors when choosing the jaw crusher for sale for a previous presentation or future purchases:

• Demand analysis

  Perform a demand analysis and determine the desired capacity, feeding size, discharge size, and crushing material. Note the required capacity in tons per hour (TPH) and the maximum and minimum sizes of the materials that will be fed and crushed by the machine.

• Design and Build Quality

  Examine the design and build quality of the jaw crusher. An excellent rugged design will minimize the effects of fatigue and wear and prolong the service life of the crusher.

  An adjustable mechanism enables operators to fine-tune the setting of the jaw crushers to achieve the desired particle size. Look for a crusher with a quick and easy adjustment mechanism.

  Choose a jaw crusher made of wear-resistant and robust materials, such as high-manganese steel. Easy-to-replace parts include the jaw plates, bearings, and bolts.

• Technology and Automation

  Confirm that the machine has automation features to increase operational efficiency. It may include remote monitoring, automated controls, and performance optimization.

• Safety Features

  Finally, choose a jaw crusher with numerous safety features and accident protections. It may include overload protection, emergency stop buttons, and safety guards.

FAQ

Q1: What is the principle of a jaw crusher?

A1: The working principle of the jaw crusher is based on a double-toggle mechanism. It uses two jaw sets for crushing materials. The jaw crusher crushes materials through the movement of the movable jaw forming a vertical process. The jaws are fixed to the mainframe and work to crush the materials between them.

Q2: What is the definition of a jaw crusher?

A2: A jaw crusher is a machine that breaks material using a motion comprising two curved surfaces. It is used in the mining and construction industries to assist in reducing large stones into smaller pieces. The equipment consists of two main parts; the jaws and the crusher.

Q3: What are the different types of jaw crushers?

A3: The jaw crushers are available in two models: single toggle and double toggle. The double toggle and single toggle jaw crusher ppt look and work differently. The most common jaw crusher, which has been discussed above, is the single toggle type. It features a movable jaw that works in a swing motion to break down stones. The jaw is linked to an eccentric shaft that allows it to move when the shaft rotates. The double toggle jaw crusher has two toggle plates that support the moving sections. They include one moving jaw and a fixed jaw pair. The double toggle jaw crusher is larger, more complex, and more expensive than the single toggle type.
