Product advantage

IsaMill is a high-speed horizontal mixing mill for fine grinding and ultrafine grinding. The grinding fineness can reach -7 microns. The speed of the stirrer is as high as 1000r / min, mainly by cylinder, Rack, transmission, disc and product separator and other components. Electric drive box to drive the disc rotation, grinding disc stirring media and materials for continuous work, the product separator is the role of the media control in the mill and the successful discharge of qualified products. Compared with conventional ball mill and tower mill, love sand grinding lower power consumption, grinding more efficient. Love sand grinding is currently in the world some of the larger industrial and mining enterprises have been applied.

Centrifugal mill is also widely used as a grinding equipment, design forms are diversified, in the design, centrifugal mill and conventional ball mill, its grinding chamber around a fixed axis of rotation, and a certain Pre-determined frequency and amplitude for mechanical vibration, rather than for simple rotation around the axis. In this way, it is not limited by the critical rotational speed such as the cylinder mill, so that the given power and the volume of the mill are greatly reduced and the grinding efficiency is remarkably improved.

According to the cylinder (grinding pipe) placement, centrifugal grinding machine is divided into vertical and horizontal two, vertical and single tube (rotor) and three (planetary) centrifugal grinding machine. Their grinding principles, unlike conventional ball mill grinding, are grounded by means of centrifugal acceleration (not by gravity acceleration) to increase the grinding force of the ball, and this centrifugal acceleration is 10-15 of the acceleration of gravity Times, it is a high acceleration grinding method. But the bushing wear speed is a relatively large drawback of centrifugal grinding.


Product introduction

    In mineral processing production, only a handful of ore after crushing, screening, can be directly sent to the smelting and most ore have measures to 0.1-0.074 mm or even more fine grinding, make useful minerals to monomer dissociation, and after sorting can send to smelting, so grinding operation is an important process in mineral processing production, if there is no single mineral dissociation so would not have chosen to good taste fine powder.In our country beneficiation production grinding machine mainly used for grinding operations ball mill, rod mill and the grinding machine.In the building materials, chemical industry, electric power, ceramics and other industrial sectors in the widespread use of various types of grinding machine, such as tube mill for cement grinding fine raw material and clinker, ball mill used in thermal power plant coal mill as boiler fuel.

Grinding machine has several kinds of classification methods, one of the most useful classification method is divided according to different grinding media: the media is a metal ball for ball mill, medium is steel bar for rod mill, grinding ore itself as the medium as the mill, ore or gravel as medium for pebble mill.

According to the cylinder shape is cylindrical and conical grinding machine can be divided into two kinds.Cone mill produced at present, the domestic has very few, so in fact the main manufacturing cylindrical grinding machine, which include short cylinder and tube.Short cylindrical grinding machine barrel the ratio of length to diameter of less than 1, since the mill is belong to this type;Tube mill cylinder (hereinafter referred to as tube mill) the ratio of length to diameter greater than 2.Portland cement ball mill is belong to this type.

According to the row way ore grinding machine is mainly can be divided into 3 types: (1) the overflow type milling machine: by the row of ore grinding side hollow shaft neck free overflow;(2) lattice type milling machine: the grinding in the row of mines the grating pore eduction, then through a hollow shaft neck outflow;(3) of peripheral milling machine: through the row of ore grinding side shell surrounding the pore eduction.In addition, there is the open mouth rod mill low row ore way and dry wind when grinding ore.

Press cylinder transmission mode can be divided into gear transmission, friction drive and central drive around three, including the surrounding most used gear transmission way, the central transmission used for tube mill.

By way of cylinder bearing can be divided into bearing, roller bearing, bearing and roller bearing 3 kinds, including bearing the most general way, and then two only for short cylinder of ball mill and pebble mill.
