In the application of gypsum board

January 15, 2020 by zzgl5656  

In the application of gypsum board, it is necessary to choose the crusher equipment that conforms to the characteristics of gypsum stone, especially the development of gypsum board roller crusher model, realizing more efficient and energy-saving operation. Quartz board production process is used for preliminary roughing. Because of the high hardness of gypsum, it is necessary to choose the right equipment of roller crusher when processing. 

The selection of gypsum board production equipment will directly influence the investment of product quality and processing system. The selection is mainly based on the characteristics of the raw material of grinding stone crusher. Jihong machinery recommends the use of double-roll crusher, which is effective for crushing gypsum board and producing gypsum glass.

The advantages of the gypsumite crusher are as follows:

(1) The crushing ratio is large, the feed size is 100~220mm, and the particle size is less than 3mm, accounting for more than 90% (of which 30%~60% is powder).

(2) The energy utilization rate is high, and the unit output power consumption is 1.29KW. H/t.

(3) Matching with ball mill, it can increase the mill output by 30%~40%, and the power consumption of the system will decrease by 20%~30%.

properties and uses of limestone powder

January 14, 2020 by zzgl5656  

This becomes a zinc antimony pigment. Zinc antimony pigment is a commonly used high quality white pigment that can be used as a raw material for paints or paintings. For the purpose of these two uses of limestone, our factory designs the raymond mill for limestone processing, which is very simple in operation, can directly make the limestone micro-powder into a suitable size, and can provide great convenience for the production of barium sulfate liquid.

The main chemical component of limestone is barium sulfate, which belongs to sulfate minerals and is a very important non-metallic mineral raw material. Its chemical properties are stable, it is insoluble in water and hydrochloric acid, non-magnetic and toxic. Barium sulphate used in the industry often contains impurities and is dyed in various colors. Due to the chemical nature of its two series, it has a wide range of uses in the industry.

After the ceramic powder is micro-powder and processed, it can be used as a zinc enamel white pigment.It can be seen from the chemical properties of limestone that the main component of limestone is barium sulfate. After the limestone is ground into a limestone powder by raymond mill, the barium sulfate is heated, and the barium sulfate can be reduced to barium sulfide by using a reducing agent, and then mixed with zinc sulfate to obtain a mixture of barium sulfate and zinc sulfide.

Gypsum mining process

Then 0-2mm size to mixing tank, then flow to hydraulic box, hydraulic box can separator different size to shaking table, shaking table base the size to choose different deck. Most time after shaking table middle gypsum also use shaking table to separator again. Then improve the gypsum process recovery rate.Our factory have alluvial project in Africa. Pls see the blow picture, it for alluvial gypsum.In the picture is only have hydraulic boxand shaking table, because this gypsum mining all of size is for 0-2mm, so it all can directly to shaking table.

Have jaw crusher, ball mill, vibration screen, shaking table, magnetic separator. Every gypsum mining contentis not different, if have much iron, or some with magnetismmetal, it can use magnetic separator take it out, then can improve the gypsum recovery rate. If for stone can grinding first then to shaking table, If the size is for 0-2mm, is can directly to shaking table for test. Our city also have tesgypsumg company, After our machine tesgypsumg.

Every gypsum is different, so need make a test, then base this to make the best flow chat. Gypsum mining process machine install Our factory (SBM MINE MACHINE FACTORY) have engineer can go customer site to help customer install machine. Before the install, we can draw a layout. Base the layout drawing to build basics. Our engineer not just for install, also will teach how to use all of machine.

Advantages of Raymond mill

January 10, 2020 by zzgl5656  

(1) Edge effect

Due to the influence of the structure of Raymond mill and the wear of the two side baffle plates, many unbroken particles are transported out with the extruded material cake. The material escaped from the side makes the pressure of the extrusion roll line unevenly distributed.

(2) Vibration and blocking run

The main reason of roller vibration is that the feeding material is not uniform and the feeding particle size distribution is too wide. Too much feed will cause the phenomenon of blocking run.

(3) Wear and repair of the extrusion roll

Usually, the surface of the extruded roll is made by surfacing welding. Cracks and peeling of the roll surface often occur in this kind of structure during operation, and axle breaking accidents are more serious.

(4) Life of bearing

The force required for crushing materials of Raymond mill is provided by the hydraulic system, which can reach hundreds of thousands.

The Development of Sand Making Machine

December 30, 2019 by zzgl5656  

The sand making machine is a new type of brick making equipment designed and manufactured in accordance with the similar characteristics and market needs at home and abroad.In 1970s, our country introduced the eight-hole sand making machine abroad.It uses river sand and a small amount of fly ash and cement to suppress lime sand bricks.However, the rotation of the disc can only press one piece of brick at a time, and the output is low.

When the large amount of industrial waste fly ash is used, there is a stratification phenomenon in the lack of exhaust. It cannot meet the requirements of the national wall reform and not meet the national industrial policy at that time.In order to improve the output and make up for the disadvantage of easy delamination of the defective products, the domestic mechanical engineers have developed a crankshaft type double crank mechanical pressing machine with two blocks, three blocks or even four blocks.

Because of its special pre pressure buffer design and the adjustment of the depth of the material, it can be qualified for the national policy of industrial structure of the new wall material with large amount of fly ash as raw material.The equipment inherits the eight-hole turntable type brick press without the need of the bracket, the advantages of the direct palletizing, and the stability and reliability of the mechanical motion, and 15~17 times a minute to ensure the production and quality of the single equipment.

The Whole Process of Fine Grinding

December 30, 2019 by zzgl5656  

The ceramic material is ground to a specified particle size in aindustrial Raymond mill apparatus as a result of the impact of the mill body on impact collision and grinding. However, the grinding process of the ceramic raw material in the barrel of the Raymond mill for limestone is very complicated.

If a single material particle is used as a research object, it may repeatedly receive the impact collision stress and the grinding extrusion stress during the grinding process of the Raymond mill. This causes the existing or newly formed cracks present on the surface of the material particles to expand, thereby forcing the material to plastically deform or break.

When the material particles are continuously ground and crushed by a industrial Raymond mill, it is difficult to further grind a certain level of new particles. The main reason is that the cracks on the surface of the newly formed material particles are fine, and the minimum crushing stress required for the expansion of this fine crack is sharply increased. Even if the final crushing stress required to grind the finely divided ceramic raw material in the ceramic Raymond mill may increase to force the particles to plastically deform, it is not enough to crush the material, that is, the material particles are no longer finely ground and have been ground too fine.

Precautions for Barite Mill

December 25, 2019 by zzgl5656  

The barite mill is short for counter-roll crusher. The barite mill has the advantages of reliable operation, simple maintenance, low operation cost and adjustable size of discharging material. According to the number of rolls, it can be divided into two-roll crusher and four-roll crusher.

The tooth shape, size and arrangement on the roll surface can be changed with the nature of the material. It can crush medium-hard and soft ores. For example, in sulphuric acid plant, the barite millis usually used to crush pyrite once, so that the diameter of pyrite can reach 20-30 mm, and then enter the double-roll crusher for secondary crushing, so that the ore diameter can reach.

Under 5 mm, it meets the requirement of fluidized bed furnace. It can be widely used in the processing of brittle and tough materials in cement, metallurgy, chemical industry, electric power, coal and other industries.
