Raymond mill is used for grinding the barite, limestone, kaolin, ceramics, and slags in the trades of mining, metallurgical industry, chemical engineering industry.
Grid type ball mill is mainly consists of cylinder, feeder, discharging device, rotating assembly, bearing and lubrication system. The grid plate has the function of isolation, which can significantly enhance the impact force of the steel ball. Therefore, the material will be fully ground with intense impact.

Crushing of highly abrasives materials, such as aluminum oxide, ferrosilicon, abrasives, glass etc.
Further features of the inventionprovide for the housing to be rotatable in unison with the beaters of the crusher, for the passages to be defined by two spaced plates interconnected by a plurality of outwardly extending vanes, for the vanes to extend in a radial direction, and for the housing to comprise an inlet duct secured to the upper plate and terminating a short distance below this plate.
HX-09 and HX-10 silica straight through impact sand making machines are small in size, simple in structure, convenient for installation and daily maintenance.
In some cases, you can reduce downtime by custom designing certain aspects of the plant. "For example, I had Grasan engineer the crushing and screening plants with quick-disconnect pins instead of bolts for almost anything we have to dismantle or take off for over-the-road travel," says Weber. "That saves a lot of time and hassle. It takes longer to work with bolts. The threads get worn after a while so the bolts need to be replaced, and it's easy to lose a nut or washer. The pins are quick, simple and chained to the equipment so you won't lose them."
Roll crushers are rugged, dependable machines, but not as productive as cone crushers with respect to volume. However, roll crushers provide very close product distribution and are excellent for chip stone, particularly when looking to avoid fines.
The cartridge is rotationally locked to the drum and hence the crusher frame via an upper flange bolted to the annular neck and a lower retaining ring bolted to the annular skirt. Conventionally, the retaining ring is formed by two tapered steel rings having opposed wedging surfaces fitted back-to-back about the main shaft. As one of the wedges is clamped against the skirt by the bolts, the opposite wedge is forced against the outside surface of the bearing cartridge to rotationally lock the cartridge within the drum. However, such conventional arrangements are disadvantageous for a number of reasons. In particular, over tightening of the retaining ring bolts forces the ring radially inward against the cartridge to an extent that the running clearance of the internal bearings is reduced. Additionally, existing retaining rings typically seize at the cartridge and/or the skirt making maintenance of the lower drive components of the crusher difficult. Furthermore, conventional bearing cartridges are difficult and inconvenient to install and remove at the crusher frame given the restricted access at the lower internal region of the crusher. The installation of a multi-component retaining ring is often problematic and increases the operational downtime of the crusher. Accordingly, what is required is a bearing cartridge and a retaining ring that addresses these problems.
There some individual crushers used for specified material, as an example of these machines we have:
Before carving a new piece of marble to fill a gap, team members first fashion a . that those early plates could grind to a precision of one-twentieth of a millimeter. . These were set into holes cut in the center of each drum; when one drum was.
The second maize milling technology is used in roller mills where the maize undergoes a series of pre-processing stages which include cleaning, tempering, de-germing, sifting, reduction, etc. These mills yield a number of maize products for various food preparations. The composition of some of these products and the milling yields are shown in table IV.2. The range of products generally varies from one mill to another depending on market requirements. The extraction rate of the dry milled products is approximately 80 per cent. In general, the majority of the output comprises prime quality grits or meals with a fat content of less than 1.0 per cent. A small proportion of the output is made up of lower quality fines or flour with a fat content of 1.0 to 2.0 per cent. The by-products (i.e. the germ and bran) make up the remaining 20 per cent of the grain input. The germ is generally further processed for the extraction of oil while the bran is used for animal feed.
