(3) sand will be transported to the hopper by loader car, then after measuring be transported to wet ball miller for milling by the belt conveyor,milled to mortar and be transported to storage tank stand-by through beating pool.
As mentioned above, the grinding machine is of vertical structure.The grinding device and powder separation device are relatively compacted as a whole.The ball mill is of the horizontal structure, powder separation device needs to be matched exclusively.Its structure is relatively loose.In addition, the length of the ball mill grinding cylinder is adjusted to meet the discharge size requirements.
According to the curves shown in figure 1 characteristics can be seen.The noise signal is ball mill can reflect the quantity of materials.In the ball speed constant, the ball is a certain period, by measuring the grinding machine, the noise signal can be directly within the ball mill detection of materials.Therefore, the stability of the grinding machine for shoes.Control air purging, make their relationship, it can control the equilibrium of the grinding mill.
The cylinder of the ball mill is a barrelor a cone.And the ratio of the length to the diameter of the cylinder issmall, and in most cases the ratio is only slightly larger than 1, and the floorarea is small, too.
Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball.
The discharging fineness of the material milled by ball mill is between 0.074-0.4mm, and that of the material milled by rod mill is between 0.833-0.147mm.
It can be divided into two types of ballmills according to the discharging ways, overflow discharge ball mill, and gratedischarge ball mill.

Until now, we have formed a whole production chain with main products: crushing machinery, grinding machinery, and auxiliary products: vibrating screen, vibrating feeding machine and other associated equipments.Products cover more than twenty models of four major series: mill series, crushing series, sand making series and ore dressing series.Advanced technology content, high reliability, low operation and maintenance cost have enabled our ball mill and dryer machine products to take the leading position in the field.Hongxing brand is the chinese famous brand.Reliable and stable quality is the key to success; our products are well known at home and abroad.Now we have tens of thousands of users throughout china and more than 30 world markets, such as: south africa, middle east, india, philippine, western europe, southeastern asia.
There are many factors that affect the price of the ball mill and grinder, such as capacity, production process, raw materials of the milling machine, manufacturers and so on.As we all know, the larger demand for production, the bigger of the milling machine, and the more investment.
In recent years, the world coal resource strains thus stimulate a coal mining rush and spur the coal mining machinery manufacturing industry.Meanwhile, coal mining technique develops from blasting, half-mechanized, fully-mechanized gradually to electrified, automatic and numerical control mining methods.Thus, the high and new technology and ball mill equipment become the international competition focus.
