Jaw Plate

Use of the product:

Supporting the use of the Star jaw crusher, it is suitable for mining, construction, water conservancy and other fields. It is suitable for the crushing of all kinds of medium and hard materials, and helps the processing and production of sand, ore, etc.

Application scenario：

The jaw plate is a core wear-resistant consumable part of the jaw crusher. It is commonly used in various production lines of mine gravel, sand and stone aggregates and metallurgical building materials. It is a key accessory for direct crushing of stone in the coarse crushing link.

The jaw plate is fixed on the moving jaw and the fixed jaw respectively, and granite, basalt, river pebble, iron ore and other hard stones are crushed by recirrative extrusion. Its wear resistance directly determines the crushing capacity and discharge specifications, and is also related to the daily consumable expenses of the equipment.

The first coarse crushing process of the sand and stone production line will use the jaw plate. Large pieces of raw stone and blasting stone will be extruded and crushed into medium-sized aggregates, and the suitable raw materials will be transported to the rear cone crusher and counter-breaker to ensure the continuous and stable production of the whole production line.

Whether it is a large open-pit mine, cement plant, or highway water conservancy infrastructure project, it cannot be separated from it. It can withstand high-intensity impact and long-term high-wear continuous operation. It is also the core accessory with the fastest jaw breakage consumption and the most frequent replacement.

FAQ：

Q：What is a jawboard? What role does it play in PE and PEX jaw rupture?

A：The jaw plate is also called the tooth plate, which is divided into fixed jaw plate and the moveable jaw plate, which is the wear-resistant accessory with the fastest damage to the jaw. The two jaw plates form a crushing cavity relative to each other. When the equipment is running, the moving jaw swings back and forth, and the stone is squeezed and split between the two tooth plates to complete the crushing. At the same time, it can protect the equipment rack and prevent the stone from directly wearing the fuselage. The wear resistance of the jaw plate directly affects the output of crushed stone, the size of the discharge and the cost of using the whole machine.

Q：Which crusher models are suitable for the jaw plate?

A：PE and PEX coarse jaw breaks on the market, and EC and JC imported replicas can all be matched, covering all specifications of coarse and medium. The styles are divided into standard tooth plate, deep cavity coarse tooth plate, fine tooth fine plate, which can be purchased in pieces, and the whole set can be shipped.

Q：Is the wear speed of the fixed jaw plate the same as that of the moving jaw plate? Do you need to replace it as a set?

A：The moving jaw plate continues to swing back and forth, and the friction impact of the stone is more frequent, and the wear will be faster than the fixed jaw plate. If it is a small and medium-sized stone farm and intermittent production, it is enough to replace which piece with serious wear separately; if it is a large-scale mine that does not stop working 24 hours a day, it is recommended to replace two sets synchronously. The crushing gap is uniform and stable, and the output particle size will not be large and small.

Q：What are the two mainstream wear-resistant materials of jaw plate, and what are the differences in applicable working conditions?

A：1. Mn13Cr2 standard high-manganese steel: good toughness and high cost performance, suitable for limestone, construction waste, bluestone and other medium-soft and low-wear materials, the first choice of small and medium-sized sand and stone factories; 2. Mn18Cr2 ultra-high manganese chromium alloy steel: stronger processing hardening performance, the surface hardness is greatly improved after impact, impact resistance, strong wear resistance, dedicated to granite, basalt, iron ore and other high-hard ores, the service life is more than 30% higher than that of Mn13Cr2.

Q：What are the quality advantages of the original jaw plate compared with ordinary castings on the market?

A：Intermediate frequency smelting integrated precision casting, complete water toughness heat treatment eliminates casting internal stress, no pores, sand holes, crack defects; tooth shape, tooth depth design fits the crushing mechanics, and the crushing efficiency is higher; the size tolerance is accurate, and there is no gap with the jaw frame, there will be no loosening, unilateral accelerated wear, and the wear resistance and anti-cracking performance is far superior Low-quality coarse castings.

Q：Do you support non-standard and old model special jaw plate customisation?

A：It supports drawing, sample and 3D modelling customisation, and can produce thickened wear-resistant models, deep cavity coarse crushed tooth plates, fine teeth fine jaw plates, imported old models for transformation special jaw plates, and the size accurately matches the equipment installation position.
