Calcium carbonate with body weight will be one of most competitive mineral filler. because of heavy calcium carbonate with good abrasive body, inexpensive, easily dispersed in the polymer, a large amount filling, a small amount oil, it’s the choice principle in the rubber, plastics, paper industry.
The average particle size of calcium carbonate with body weight is one of the most important physical properties, in general, the average particle size of less than 2μm is fine level, 2-10μm is fine-grained level, more than 10μm is coarser.
Development of limestone powder products, change the mining resources advantages into economic advantages.
The production methods of calcium carbonate with body weight is divided dry and wet. mainly dry method. in the dry production, the selection of equipment Raymond mill, centrifugal mill, vibrating mill and jet mill. Powder products from Raymond mill is mainly coarser powder with 38-74μm, but by the production control and additional air classification device connected, can produce the intensity of 3μm products. vibrating mill can be used in wet or dry powder occasions, grinding media may need to use alloy or ceramic spheres, particle size is 3-80μm.
Regards the exploitation of new mines as the interests of whole society. overall planning the use of resources, coordination arrangements, the mine's production, supply and marketing a comprehensive balance in order to get the best investment returns and social benefits.
Choosing Jaw Crusher to Bring More Benefit
One of the more versatile of the mining crushers is a jaw crusher. A used jaw crusher can be used for quarried materials, sand and gravel and recycling projects. Also known as a toggle crusher, jaw crusher use two 'jaws', one fixed and the other moving, to move ore down a tapered chute so material is crushed progressively into smaller pieces. A weighted flywheel moves the shaft to create a motion that closes the gap at the bottom where the ore is crushed to pieces small enough to fit through the bottom. Used jaw crusher can be found in single or double toggle models.
Gyrator crusher are similar in design to jaw crusher, consisting of a concave surface and a conical head, with ore materials traveling downward between two surfaces that progressively crush the ore. Unlike jaw crushers, the inner cone of a gyrator crusher has a slight circular movement on the central vertical spindle that gyrates when the ore material is fed down the chute. This action causes the crushing by the closing of the gap between the mantle line mounted on the spindle and the fixed concave liners. Used gyrator crushers can be used for primary or secondary crushing but often such equipment is the primary crusher in a mine or ore processing plant.
Unlike jaw and gyratory crushers that use pressure to perform the crushing an impact crusher uses the force of impact to pulverize soft or non-abrasive mining ores such as coal, seeds and limestone. Used impact crushers are found in two models, horizontal shaft and vertical shaft. Most impact crushers feature a cage surrounding that has openings on the bottom, end or sides where the crushed material can escape when it has been smashed down to the appropriate size.
