适用矿山、煤碳、洗煤厂、炼焦厂、发电厂、化工厂及科研院校试验室进行煤、铝土等物料粉碎制样，替代手工磨样。自动除尘、无污染、适用室内作业。本产品由原地矿部唯一指定企业生产，执行行业标准。

Laboratory Sealed Disk Crusher and Vertical Pulverizer are applicable to comminution of coal, bauxite and other materials in labs of mine, coal preparation plant, coking plant, power plant, chemical plant, research institute and institutions of higher learning for making samples instead of grinding samples manually. They are suitable to be operated indoors with automatic removal of dust and no pollutions produced. The products are produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

本机器主要是由机体、底座、主轴、动磨盘、固定磨盘、端盖上盖及料斗等构成。经三角带将动力传给皮带轮带动主轴旋转，使动磨盘固定磨盘相对运动，从而使试样粉碎。出料粒度可通过手轮，主轴等调整磨盘间隙达到控制粒度的目的。

This machine is mainly composed of body, base, main shaft, dynamic  grinding disk, stationary grinding disk, upper end cover and hopper. It  transmits the power through the V-belt to be pulley which then drives the  rotation of the main shaft, to allow relative motion between the dynamic  grinding disk and the stationary grinding disk and further to crush samples.  The granule sizes of discharging materials can be controlled when the gap  between the grinding disks is adjusted through hand wheel, main shaft, etc.

机体安装于底座之上，它的传动部分有传动轴、轴承、动磨盘、皮带轮组成，工作室由端盖、调节轴、固定磨盘、动磨盘，进料口组成。

The machine body is installed above the base. Its transmission  part consists of transmission shaft, bearing, dynamic grinding disk, and belt  pulley while the working chamber consists of end cover, regulating shaft,  stationary grinding disk, dynamic grinding disk, and feed inlet.

物料粉碎在工作室内进行，物料从端盖上方的进料口加入，进入两磨盘中间，由于挤压作用使试样粉碎，粉碎后试样从两磨盘中间的间隙内流出，落到下面的料斗中。

Materials are crushed in the working chamber. Materials are added  from the feed inlet on the top of the end cover and go into the middle of two  grinding disks. Under the squeezing action, the samples are crushed. The  crushed samples flow out from the gap in the middle of two grinding disks and  fall onto the hopper below.

调节机构的原理是：旋转手轮，使用权调节轴前进或后退，从而调节了两磨盘的间隙，调节了物料的粒度。

he working principle  of regulating machanism: Turn the hand wheel to move the regulating shaft  forward or backward, so as to adjust the gap between two grinding disks and the  granule size of materials.
