Pros and Cons

Jaw Crushers are generally smaller in size in comparison to other crushers. Thus, they are ideal for smaller and tight spaces and can handle different types of material, including hard and soft ones. Still, the K-JC503 has several other advantages and disadvantages.

  • Simple Structure. The Komplet K-JC503 is a mobile mini crusher with a hydraulically adjustable 19″ x 10″ single toggle jaw crusher. It has a simple structure designed for ease of use, cost-effectiveness, and reliable operation. The jaw crusher features a moveable jaw, a large and deep opening that enables large feed, and a constant discharge opening width that produces uniform-sized particles.
  • Easy Mobility. The mini mobile jaw crusher is equipped with wireless remote control and rubber tracks, making it easy for the equipment to be mobile on-site while crushing and transporting recycled concrete.
  • Low Manufacturing. CostK-JC503 portable jaw crusher creates an opportunity to do more and save more money. Here’s due to the ability to crush and move crushed concrete from the site with this equipment. Thus, a contractor can save money on excavation and waste removal. In addition, with the Komplet K-JC503, one could easily convert the crushed waste to a byproduct that a contractor could repurpose onsite.
  • Small Crushing Ratio. The Komplet K-JC503, like all jaw crushers, has a smaller crushing ratio. However, unlike its counterpart, the K-JC 704, which has an output size of 3/4″ to 3-1/4″ at a rate of up to 90 tons per hour. K-JC503 can only give this output size at a rate of 30 or 34 US tons per hour.

Jaw Crusher Working Principle

These rock breakers have been around for nearly 200 years and are known as primary crushers. They are used almost exclusively for the first stage of crushing hard stones and demolishing construction sites. This is major because they can efficiently break down different types of material, including the hardest ones, into more manageable sizes for easy processing into recyclable materials.

Jaw Crushers use the compression style to break down materials. Typically, they have two crushing jaws – one is stationary, and the other isn’t. These crushing jaws produce the mechanical pressure for crushing these materials, with the stationery jaw holding the material in place while force is exerted on it. The moveable jaw moves around 250 to 400 times per minute to subject the material to compression.

These two crushing jaws mounted in a V-shaped alignment are where the materials are dropped off. It is called the crushing chamber. Here, the opening is similar to a ‘V’ with a wide opening down to the output gap responsible for the crushed output size. The crushed materials remain in the jaw until it can pass through the set gap.

User-friendly and Safe 

Jaw Crushers can handle different materials used in various industries, mining, quarrying, demolition sites, and chemical industries. Therefore, it is vital to discuss how dangerous improper handling of this equipment is. The Health and Safety Executive’s guidance for the safe operation of mobile jaw crushers reported that this equipment user might be at risk of exposure to being struck by materials ejected from the crusher, dust, noise, etc.

As such, despite the E-JC 503 being user-friendly, it is imperative to pay attention to safety guidelines to ensure it’s safe to use. Risks of using a mobile crusher are mostly dependent on the industry, but some of the common risks of operating a jaw crusher include:

  • Slips or falls.
  • Machinery guarding.
  • Poorly planned operation
  • Clearing blocked or stuck jaw crushers.
  • Whole body vibration.

Here are some simple tips to ensure a smooth and efficient operation.

  • Train and instruct the crushers driver.
  • Follow the manufacturer’s recommendation on loads and feed control.
  • Regular inspection and maintenance.
  • Wear a safety belt and glass at all times.
  • Always check or replace the machinery guard before use.
