hammer crusher vs jaw crusher | which is better (7 tips) | m&c

Hammer crusher and jaw crusher are common crushing equipment in the mine/building materials industry. They have large feed inlet and high crushing efficiency and are mainly used for coarse crushing of various ore materials. But they are different in many parts, which is better? Table of Contents 1. Different Appearance and Working Principle2. Different for Applicable Materials3. Different Discharging Adjustment Methods4. Different Structure and Wearing Parts5. Different Configuration of Production Line6. Different Application of Aggregate Line7. Which is Better, Hammer Crusher or Jaw Crusher

The appearance and working principle of the 2 crushers are different. The jaw crusher is of the curved dynamic extrusion type, and the materials are crushed in the crushing cavity composed of the moving jaw and the fixed jaw. The hammer crusher is mainly broken by the impact, shear and tear of the rotating hammer head, the mutual impact between materials and the counterattack of the lining plate.

Hammer crusher is mainly used to crush ores with low hardness, and its compressive strength is generally lower than 200Mpa, such as limestone, bluestone, coal gangue, etc. When crushing hard materials, the hammer head is seriously worn and the cost of frequent replacement is high.

The adjustment of the discharging granularity of the hammer crusher is realized by changing the bottom sieve plate. There are three adjustment modes of jaw crusher: base plate adjustment, wedge adjustment and hydraulic cylinder.

Hammer Crusher is rarely used in aggregate production line. Although the process is simple, the yield is low, it is easy to be over crushed, and there are many powdery materials. Moreover, the finished aggregate may have microcracks, low compressive strength, which will affect the quality of aggregate, sales and price. Therefore, it is often used as auxiliary sand making machine.

The main advantage of hammer crusher is that the ore with low hardness can be formed in one time. For the production line with output < 300t/h, a single hammer crusher can replace a jaw crusehr + a impact crusehr.

The main advantages of jaw crusehr are simple structure, convenient maintenance, high wear resistance, high cost performance, suitable for all kinds of hard ores. However, due to the high content of needle and flake aggregates in the discharge, it is necessary to cooperate with impact crusher for shaping.

Leading supplier of high alloy castings and forgings. There are 4 companies with sales of more than 100 million yuan, across the 4 major areas of wear resistance, heat resistance, corrosion resistance, and machinery

Forging crusher hammer head is suitable for crushing cobblestone, coal gangue, limestone, etc. Forging crusher hammer head uses high-quality train wheel steel (material 65Mn, good impact resistance, strong toughness, good abrasion resistance, not easy to break). The metal blank is repeatedly forged using forging machinery to deform it to obtain certain mechanical properties. A certain shape and size, after a special quenching and heat treatment method, to ensure that the working area of the hammer head has high hardness and high wear resistance. Forging can eliminate defects such as as-cast looseness caused by metal in the smelting process and optimize the microstructure. At the same time, the mechanical properties of forgings are generally better than those of castings because the complete metal streamline is preserved. Forged hammer heads are popular with customers because of their low price, economy and durability.

Alloyed high-manganese steel wear-resistant hammer head with reliable quality and three times the wear resistance of traditional high-manganese steel. This crusher hammer head is widely used in large limestone crushers supported by domestic dry-dried cement production lines.

Mn13, Mn13Cr2 and Mn18Cr2. Suitable for large and medium-sized crusher tooth plate, mortar wall, crushing wall and large excavator bucket teeth and other strong impact conditions. Can also be used as ball mill, semi-self-grinding machine, self-grinding liner.

With the continuous development of wear-resistant materials, high manganese steel has gradually become unsuitable for the development of modern foundry industry. Replaced by chrome molybdenum alloy steel, high chromium cast iron and nickel hard cast iron. However, the high toughness of high manganese steel is unmatched by other wear-resistant materials.

The hammer head of high manganese steel crusher has good toughness, good processability and low price. Its main feature is that under the action of large impact or contact stress, the surface layer will rapidly undergo work hardening, and its work hardening index is higher than other materials. 5 7 times, the wear resistance has been greatly improved. However, the high manganese steel crusher hammer head has higher requirements for the overall performance of the crusher. If the physical impact force is insufficient or the contact stress is small in actual work, the surface cannot be rapidly processed and hardened, so that it cannot exert its wear resistance. Sex. Therefore, we hope that the majority of customers should choose according to the actual parameters of the equipment before use, and if necessary, can modify the equipment to make the most of its economic benefits.

High hammer alloy crusher has excellent hardness and is a high-quality wear-resistant material. It has been widely used in fine crushers (third-generation sand making machines) and impact crushers with supporting hammer frames, but high chromium alloy toughness. Poor, easy to break without hammer support. High chrome composite hammer head, that is, high manganese steel is used for the hammer handle, and high chromium alloy is used for the hammer head working area. The two are combined to make the hammer head have high hardness and the hammer shank has high toughness. The respective advantages of the materials overcome the shortcomings of a single material and meet the requirements for the performance of the hammer head. Particularly suitable for crushing high hardness materials, such as quartz stone and basalt. But its manufacturing process is complicated, the process requirements are strict, and the price is high.

Compared with other materials, the cemented carbide hammer head has higher hardness, flexural strength and impact, thermal fatigue resistance, good thermal hardness, low cost, etc., and solves the cracks, desoldering, Collapse, drop blocks, etc.
