Limestone is graded according to nominal size; smaller numbers indicate a larger particle size, and bigger numbers indicate smaller stone. Sizes larger then 4 to 6 are denoted by names like Rip-Rap and Gabion stone. Crusher Run products contain all sizes smaller than their name specifies; 1-1/2 inch Crusher Run has a maximum size of 1-1/2 and about 35% smaller than . Sizes smaller than are referred to by the number of openings per inch that they will pass thru; a size is a #4, a 1/40th is a #40 and a 1/200th is a #200. AASHTO, the American Association of State Highway and Transportation Officials, specifies many standard sizes of crushed stone used by many state DOTs. They are specified by numbers, such as #1, #2, #57, #9, etc. but are very different from screen size specifications openings per inch mentioned above. Typical uses for AASHTO sizes are: #1, #2, #3, #4; Used around construction sites, logging sites, farms, and muddy areas as a base course for roads. These sizes do not grade smoothly, and may be difficult to walk on. A smaller size is typically used to finish the top surface. #57, #67, #7; Used in concrete and asphalt, septic and drain fields, under concrete slabs, and for backfilling free draining, non compacted applications like basement walls. #8 and #9; Used for surface treating asphalt roads, abrasives during snow and ice in winter, pipe bedding, and to provide a smooth surface. Not as stable as larger sizes. Manufactured Sand ; Smallest available, it is crushed sand rather than naturally occurring like in a river or at a beach. Two kinds are available, the C33 Specification is for concrete and asphalt, and the non spec sand is for bedding, agricultural use and fine grading. Crusher Run, #, 1-1/2, and ; All contain a top size as indicated, down to very fine sizes. When properly compacted, these materials provide a smooth, dense, durable surface. These sizes are used principally as road surfaces and shoulders and finished grade construction surfaces. Rip-Rap and Gabion; Used for slope protection and landscaping, sizes up to 36 Coarse Ground Agricultural Lime; Air classified, 85% min CaCo3 Equivalent

aggregate crushing plant-high safety high efficiency stable performance

As a result of the great development of the basic construction and the reconstruction of the towns and the rapid rise of the high-rise buildings, the old-style buildings die out, and the waste of the construction wastes is directly buried without treatment, Then it will cause long-lasting harm to our living environment. Crusher plant can deal with construction wastes well.

Our company, a professional construction machinery manufacturer in China, provides top quality crushing plant, asphalt plant, concrete batching plant for sale. If you are interested, just contact with us now!

Compared with the mobile crushing plant, the stationary crushing screen plant has no tires. In view of the present situation of construction waste treatment in our country, crushing plant has strong advantages, but with the increasing maturity of construction waste disposal market, it will slowly be transformed into fixed crushing plant, that is to say, mobile crushing station is transitional equipment, and slowly will be converted into fixed type.

It is mainly used for fields like metallurgical, chemical, building material, hydro-power that needs material processing, especially for highway, railway, hydro-power with the operation of mobile stone. Customers can choose multiple configuration according to types of raw material, size and finished material requirements.

Mobile crusher plant can not only reduce the cost of transportation, but also cooperate with brick making machine to make the raw material into finished products at one time. With the increasing market demand, various types of crushing plant are needed, such as jaw mobile crushing plant, tire mobile crushing plant and other types. These plants can produce product with high quality, high crushing ratio, reliable performance.

Vibration feeder takes eccentric shaft as excitation source, gear transmission, low noise, stable operation, long life, and it can screen fine material in advance to make crusher more efficient. Adjust the gap grid design to prevent material blockage. Customers can selectively install speed-regulating motor, easy to control the feed quantity, no need for frequent start-up of the motor.

Circular vibrating screen is a kind of screening machine, which mainly produces centrifugal inertia force (excitation force) with radial variation because of the unbalanced rotation of the vibrating wheel of the exciter. Itdrives the screen box and makes the screen vibrate. The trajectory of the screen frame is elliptical. The material on the screen is thrown up by the upward movement of the screen surface, and then falls back to the screen surface after a distance. In this way, the screening is completed in the process of moving from the feed end to the discharge end. The amplitude of the vibrating screen can be adjusted by changing the weight and position of the counterweight.

As far as the counterattack crusher is concerned, the rotor rotates at high speed under the drive of the motor while working, and the material entered from the feed port is hit by the plate hammer on the rotor, which is broken by the high speed impact of the plate hammer; the broken material is hit back on the liner and broken again; later, it is discharged from the outlet. Adjusting the gap between counterattack frame and rotor frame can change the particle size and shape of material.

The material is uniformly transported into the crusher through the feeder, and after the crusher is initially broken, the closed circuit system is formed by the circular vibrating screen to realize the cyclic crushing of the material, and the material in accordance with the grain size requirements is output by the conveyor, so as to achieve the production purpose.

Before the operation, check whether the supporting equipment can run normally, such as crusher, feeder, and so on, whether the connection of these supporting equipment is loose or falling off, and whether the transmission device is abnormal. Especially the crusher, ensure that there is no residual materials in the crusher. In addition, because the working environment of the stone crushing plant is complex, the tire of the mobile crushing station is a vulnerable part, the user should also check whether the tires can work normally before carrying out the operation, so as to ensure the overall performance and normal operation.

The circuit problem of the whole machine in the operation process is a problem that the user needs to pay attention to. If there are special noises, odors or sparks in the working process, stop the operation immediately, maintain in time and never work by force. Otherwise, the whole equipment and motor may be damaged, and it is easy to cause inestimable losses to the user.

Before the stop of the crushing plant, the user must ensure that all the equipment can stop after all the materials are discharged. After the mobile crusher stops, the user should also check the circuit of the equipment, the supporting equipment and lubrication in time. For any abnormal condition, repair and maintain in time. In addition, due to the complexity of the working environment of the aggregate crushing plant, users need to clean and maintain the equipment in time after operation.
