Recently, a customer from Guizhou customers bought a ZSJ-series crusher for the production of high quality M-sand, which is not a single case in that province. It is reported that the project uses limestone as raw material for sand making, with an output of 180-250 tons per hour. Finished product sand is mainly used in the construction field. Due to its excellent graininess and reasonable particle gradation, the final products have quite sound sales.

ZSJ fine crusher is especially suitable for the shaping and crushing operation of moderate hardness rock such as limestone. With maximum feed size of 250mm, it can produce the common types of crushed sand for construction including 3.3mm, 4.75mm and 5mm, etc. As to the structure, it is mainly composed of the body, crushing plate, rotor, pendulum, rotary drive, sieve plate and other components. In operation, the two rotors are operated under the driving of two or four low-voltage motors. At this time, the limestone raw materials satisfying the size requirements of the sand making machine enter the crushing chamber through the feed inlet and are hit by high-speed hammerheads; then the stones will hit each other after obtaining dynamic energy. Through repeated collision, the crushed sand is produced with particle size between 0 and 10mm.

Based on the above introduction for working principle, it is not difficult to find that the ZSJ fine crusher uses hammers to crush the material, so it belongs to typical hammer crusher. Its advantages are mainly as follows:

1. During the operation process, the stone materials contact less with working parts of the machine the less direct contact, which effectively reduces the hammer wear, at the same time, through the hit of hammers, impact of counterattack and mutual collision of the materials, the limestone can be fully crushed, so the grain size of M-sand can be optimized to the greatest extent.

2.Compared to other crusher, hammer mill has simpler structure. It means that it is very convenient to carry out installation, maintenance or replacement of parts in the later stage, greatly saving customer’s time and money costs.

3. Hammers are made from chromium alloy, the most advanced technology and wear-resistant metal parts, which prolongs the service life of the crusher machine by more than 20%.

4. In addition to large output and crushing ratio, ZSJ fine crusher consumes 30% less power for the same output compared to impact crusher, the common type in the market.

5. Manpower is not required for the operation equipment. Featured by high degree of automation and low noise, it has won much praise from users.

The ZSJ crusher manufactured by Zhongyu Dingli is typical hammer mill. With the hourly output from 20 to 280 ton, it is mainly for the shaping the stone with middle hardness and producing crushed sand. If you have any interest, please do not hesitate to contact us for more detailed information.
