The high-grade fossil limestone or nummulitic limestone deposits of Assam are geologically known as Sylhet limestone as these belong to that groups of rocks. The limestone deposits are confined in areas of Garo hills, united Khasi and Jaintia hills, Cachar hills and Mikir hills. One of the largest outcrops of limestone is at the foot of the Khasi hills. Vast deposits of high-grade limestone are best observed in the Jowai area. Lime stones of the Khasi and Jaintia hills can be used for manufacture of cement and for lime-burning purposes. It can be used in chemical industries and for metallurgical purposes. The limestone deposits of the state offer vast scope for developing innumerable industries where limestone is required.

Limestone occurrence in Assam are confined to North Cachar Hills and Karbi Anglong districts. The Sylhet limestones continue into the North Cachar Hills across the Kharkor and Kopili rivers. They are found to cover an extensive area near Garampani to The north-east of the confluence of the two rivers. In Karbi Anglong, the principal occurrences are Silbheta-Meyong Disa,Chopung Hills,Jarapagaon,Koilajan Bar Harihajan and Doigrung. Of these the first two are rather high in iron even though the reserves are large;reserves in Silbheta-Meyong Disa are 38 million tonnes,in Chopang Hills 17 million tonnes and in Jarapagaon 6.5 million tonnes. The total reserves between Koilajan and Kidimithapa are of the order of 81 million tonnes of which 43 million tonnes are reckoned as being high in silica.

The State Directorate of Geology and Mining has proved that 3 million tonnes of these limestones are of cement grade. Average composition of the samples analysed gave,Ca0 47.20 per cent and Mg0 1.30 per cent. Silica varies between 8 and 12 per cent and alumina and ferric oxide 1 and 3 per cent and 2 and 4 per cent respectively. In Bar Harihajan of Karbi Anglong district,about 4.5 million tonnes are likely to be available at Saini Langso,Chota Harihajan and Disai Nala analysing. Exposures of limestones are known along the Doigrung river 19 kms. south of Golaghat but the quantity of reserves have not been estimated. One available analysis estimates CaCo3 72-90 per cent,MgCo3 7.33 per cent,Mg0+Al203 +Fe203 9.0 per cent and Insolubes 10.70 per cent.

Cement Manufacture constitutes the most important use of limestone. Next in order of importance is its use as a fluxing agent in the metallurgical industry. Other uses, apart from lime for building mortar,are in the manufacture of various chemicals,glass,refining of sugar,oil and as a filler.

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.
