What is Diatomaceous earth ?

Diatomaceous earth contains a small amount of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 and organic matter. SiO2 generally accounts for more than 80%, up to 94%. The iron oxide content of high-quality diatomite is generally 1~1.5%, and the alumina content is 3~6%. The mineral composition of diatomite is mainly opal and its variants, followed by clay minerals – hydromica, kaolinite and mineral debris. Mineral debris includes quartz, feldspar, biotite and organic matter. The content of organic matter ranges from trace to more than 30%. The color of diatomite is white, off-white, gray and light taupe, etc. It has the properties of fineness, looseness, light weight, porous, water absorption and strong permeability.

The significance of high pressure large ball press machine

information about ball press machine Ball press machine is a key suppressing machine in the pellet technology complete equipment developed and designed on the principle of extrusion molding for powder material. Our company received the national patent of invention certificate of large ball press machine with patent No. ZL2007.1.0163951.4. Recently, the first GY2412 ball press machine has been successfully manufactured in our factory with diameter of press roll 2.4 meter and width 1.2 meter. The capacity of the machine can reach 50-100t/h according to different material. Our product is the largest high-pressure ball press machine of highest pressure and largest capacity featuring in advanced product design theory, rational structure, affordable forcing feeding, adjustable pressure, feeding intellectualization, ball production automation with inlaid rolling skin easy to exchange and maintain. The significance of ball press machine I t helps realize the lar...

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...
