Embodiment Construction

[0018] The following figures further illustrate the present invention in conjunction with the accompanying drawings and embodiments.

[0019] figure 1 Among them, the movable roller 1 and the fixed roller 2 have different diameters, and the rollers have a frustum-shaped structure along the axial direction. Simultaneously both carry out differential movement. Photoelectric sensor 3 is installed on movable roller 1, and it is made up of light-emitting diode installed on one side of roller 1 and the phototransistor of the other side. The photoelectric sensor 3 is connected to the solenoid valve, the solenoid valve is connected to the flap hydraulic cylinder 5, the flap hydraulic cylinder 5 is connected to the flap 4, the flap 4 is located below the two roller gaps, and the rotation angle of the flap 4 ranges from 0 to 70 degrees , it is advisable to discharge smoothly from turnover plate 4 with waste material. Below the frame is a waste discharge port 6.

Abstract

The invention discloses a cement final grinding roller press with material grinding and waste discharging functions, and aims to solve the problems that the current cement final grinding roller press is complex in structure and relatively high in manufacturing and operation costs and the quality of a cement product is lowered because wastes are mixed in a product. The cement final grinding roller press disclosed by the invention has the advantages of reasonable structure, convenience in use, lower cost, capability of automatically discharging wastes and improving the quality of the cement product, and the like. The cement final grinding roller press structurally comprises two rollers which are arranged on a rack and shaped like a frustum along the axis direction, wherein one of the rollers is a movable roller, the other roller is a fixed roller, and the two rollers rotate at different speeds. The movable roller is pressurized through a hydraulic cylinder and used for squeezing and grinding materials. A waste discharging device is arranged below the two rollers.

Description

technical field [0001] The invention relates to equipment used in the cement industry, in particular to a roller press used in a cement final grinding system. Background technique [0002] Roller press is a kind of grinding equipment for brittle materials, suitable for grinding cement clinker, granular blast furnace slag, cement raw materials, gypsum, cement, quartz sand, iron ore, etc. It is crushed by high-pressure extrusion of two rollers with flat roller surfaces and relatively rotating rollers. As a mature high-efficiency and energy-saving product, the roller press has been widely used in the cement grinding industry and has achieved remarkable results. However, because the crystal shape of the material extruded by the roller press is flake or columnar, as cement final grinding equipment, the produced cement has the defects of large water demand and reduced concrete strength, so it is usually necessary to form a pre-processing equipment with a roller press. Grinding s...
