Overview
Mechtech’s top-of-the-line MTJ-type jaw crushers are designed specifically for primary applications where resizing is the primary goal. They allow the material to be handled within the confines of your crushing plant. The jaw crusher must have a good and homogeneous feed level to perform optimally.
Salient Features
HYDRAULIC JACKS
Hydraulic jacks help in the CSS range which has a significant effect on product gradation, capacity, and power draw.
LARGE FEED ACCEPTANCE CAPABILITIES
The large feed enables crush both tough feed materials like rocks in quarry fields and hard materiallumps in the mineral industry effectively and economically.
HEAVY-DUTY WELDED FRAME DESIGN
The plate takes heavy impacts from the material and protects the swing jaw, shaft, and bearing during crushing. It also helps to direct material into the crushing chamber.
HIGH CAPACITY WITH A HIGH REDUCTION RATIO:
The jaw crusher's bulk density, crushability, and size distribution result in a high capacity and reduction ratio
OPTIMIZED NIP ANGLES
Jaw crushers have nip angles between 16–23°.A good nip angle means a high throughput capacity of the crusher.

FAQ
The MTJ jaw crusher is built to handle various feed material, but it has the following
limitations:
The top size should not exceed the 80% dimension of the width of the crusher .However,
occasionally the bigger feed size can be handle is the 3rd dimension is bigger and fed
diagonally into the crushing chamber.
Prior to entering the crushing chamber, fine material with a particle size equivalent to the
closed-side setting should be removed. Therefore, it will increase the crushing efficiency and
reduce the wear and tear on the jaw plates.
Our jaw crusher’s line includes: MTJ and DTJ series.
MTJ Series Jaw Crushers are grease lubricated crusher and DTJC Series Jaw Crushers are oil
lubricated crushers.
If the material is easily crushed and not excessively abrasive, single toggle jaw crushers can
be the best choice.
If the material is hard and abrasive in nature, double toggle jaw crusher (DTJC Series) can be
the best choice.
Determine the Jaw Crusher size for your application using the following information:
• A maximum material lump or largest size expected to be crushed
• Tons per hour rate needing to be crushed
• Desired size of discharge material needed
• Operating hours per day
Crushers can be customised based on your expectations. Working with a skilled material handling solutions partner like Mechtech is the best approach to locate the perfect crushers
for your specific operation. We assist you in finding the apt solutions to extract material,
break it down into usable output, and deliver it to market as economically and efficiently as
possible. The appropriate partner can assist you in developing a unique crushing circuit to
increase efficiency and improve your business.
