How many ways to improve the seal of the grinding head of a hematite ball mill?

There are several ways to improve the sealing of the grinding head of the hematite ball mill: 1. A 200mm long spiral cylinder is added at the outer end of the feeding screw cylinder, the spiral blades are welded on site, and the extension section is connected with the mill together with the original spiral cylinder with screws; 2. Add a felt positioning ring at the outer end of the extension section, install the industrial felt after splitting, one side is coated with butter, and the ring is connected with the 200mm spiral cylinder of the extension section with a countersunk screw; 3. Set up a friction sealing ring at the outer end of the felt, put it on the feed hopper, make and weld two stop rods on the spot, so that it can not rotate, and use a number of springs to resist it later, and the spring seat is welded together with the feed hopper, so that the end face of the retaining ring is always attached to the felt, and is not affected by the wear of the felt part. There should be a gap of 5mm between the sealing ring and the outer diameter of the feed hopper cylinder, this gap is blocked with cotton dipped in butter, and a pressing plate is added to the retaining ring, which is tightened with a screw and the sealing ring.

When installing the feed hopper, pay attention to the installation position to retreat 200mm and let go of the length of the extended section spiral cylinder.

When the mineral enters the ball mill for grinding operation to produce overgrinding, the bond force of the ore particles itself is greater than its own inertial force, so that the beneficiation process becomes useless, and the consequence is the reduction of concentrate grade and the reduction of metal rate, the reason for the existence of this phenomenon, mainly the following factors. (1) Single grinding equipment. China's grinding equipment has a single variety, and the concentrator can only choose from only a few types on the current market, which is nothing more than self-grinding, ball milling, and rod grinding.

Self-grinding is favored by mineral processing workers for its strong selective grinding effect, but the existence of its refractory particles has caused a great obstacle to its popularization and application. This is because the crushing system for processing refractory particles has very strict restrictions on the entry of ironware, and it is difficult to remove non-ferromagnetic metals, and it is difficult to separate ferromagnetic metals from magnetic minerals, so it is difficult for the stubborn stone crushing system to operate, so that the production capacity of the ball mill cannot be improved, and the production requirements of mineral processing cannot be met, which limits the popularization and application of the self-grinding machine in the magnetite mine. Precise iron removal device and stubborn stone crushing system to relax the restrictions on iron tools are the direction of future research.
