The double roll crusher is suitable for crushing hard, hard, and soft materials with a tensile strength below 300Mpa and a moisture content below 35, and for crushing work. Double roller crushers can be widely used in fields such as mining, thermal power plants, concrete, porcelain, metallurgical industry, chemical plants, decorative building materials, etc. The equipment of the double roll crusher manufacturer has the characteristics of extremely low application and maintenance costs, reliable characteristics, low smoke and dust, and poor sound quality.

Double toothed roller crusher, also known as 2PGC crusher, belongs to the category of double roller crusher. The roller surface can be divided into large and small toothed rollers. The double toothed roller crusher can be adjusted and manufactured according to the necessary specifications of raw materials, suitable for ductile and soft raw materials. The double toothed roll crusher is suitable for pelletizing, coal, concrete, aluminosilicate, Laminated glass, porcelain and other fields. The double toothed roll crusher is suitable for crushing ductile raw materials with medium strength and below. It is mainly used for the crushing of iron ore.

The twin roll crusher is equipped with two rollers. According to the particle size distribution required by the customer, the roller surface is divided into two types: flat roller surface and spray welded roller surface. If the tensile strength of raw materials exceeds 200Mpa, the intensified model can be selected.

The flat roll surface model of the twin roll crusher is applicable to the crushing work where the feed particle size distribution is less than 80mm and the finished product particle size distribution is specified as 50 meshes -20mm. For example, using river pebbles and urban garbage to make sand manually; Crushed copper ore and artificial quartz stone in the coal industry: raw materials for crushing in the porcelain industry, glass crushed coke and quicklime powder in the industry; Coal powder for coking and crushing; Crushing various raw materials in the chemical manufacturing industry; Or a crushing site similar to the above. The spray welding roll surface model is applicable to the work of medium crushing with the feed particle size distribution of less than 110Mm and the finished product particle size distribution of 3-30mm. Pre crushing of light burned dolomite, dolomite, and polymer materials in front of ball mills in coal enterprises: pre crushing of coal before grinding in the coal water slurry field, pre crushing of slag, iron ore sand, and ferrosilicon ore before grinding in the copper mine field: crushing various types of iron ore in brick and tile factories to make environmentally friendly bricks; crushing of electric coal in power plants; Or a crushing site similar to the above.

Principle of Double Toothed Roller Crusher

The double toothed roll crusher uses two aluminum alloy rollers with high toughness and wear resistance, and the high extrusion working pressure caused by the relative rotation is used to crush the raw materials. After the raw materials enter the gap between the two rollers (V-shaped crushing chamber), they are subject to the extrusion working pressure and shear stress effect of the relative rotation of the two rollers. Under the extrusion, cutting and meshing, the materials are crushed into the necessary particle size distribution and then discharged from the row mouth below the equipment.
